Mobil 1 vs Castrol Edge (8 x better)?
 

I watched the video that was an ad banner here on the forum website. 8X better is what I would say a big improvement. What do you guys think? :bigears

I watched it with an open mind and they did a good job beating down Mobil 1.

http://www.castroledgeusa.com/?utm_s...n=Castrol_EDGE

Wake up Corvette owners. The only reason GM, and others, "recommend" Mobil One is because they get paid to do so. I use Castrol SynTech in all my engines from cars to boats to motorcycles to lawn mowers.

I buy the really cheap stuff that nobody recommends. Generic oil in a white can with black lettering.

Look, oil, just like soap, is pretty much a commodity item. Companies all have to figure out how to convince you to buy there oil over the others.

I believe that is why there are standards that a mfg'er has and if an oil is tested (properly) and meets/exceeds the standard then it will do.

I used Pennzoil in my 87 T-bird turbo when I had that car, got up to 192K miles, no turbo problems or any other engine problems. Just changed the oil regularly and made sure I did all the regular fluid flushes. Sold it in running condition, stock turbo and all.

Who keeps paying people to diss Mobile 1 ?

A buddy and I were looking to distribute AMSoil synthetic oil when it first got started.

There is ABSOLUTELY a difference between dino blends and synth blends.

After 2-3k miles, most dino oils have degraded to the point of change. Without exception, every single one we tested degraded similarly.

Now the synthetics are not always as advertised. AMSoils pitch was the 15k mile oil change.

We had it tested and at 8k miles most of the esters were still in tact and no noticeable dillusion was noted. At 10k miles the oil was trash, roughly 10% of esters left. Time for an oil change.

But in debunking their claim we learned so much more about oils, synthetic or otherwise.

Having tested just about any oil you can think of now my reccomendations will always be:

Dino Oil: Castrol GTX

Synthetics: Redline, Royal Purple or Mobil 1.

Take in consideration this Castrol oil you are talking about wasn't out yet but anyone can follow the same process we did and have it tested to see for yourself. Don't take my word for it or anyone else's for that matter. Run Mobil 1 through the car and send a sample in 3k mile increments. Switch to 1k mile increments over 8k and 500 mile increments over 10k if it is still useable at this point. Then repeat the steps for this new Castrol synthetic blend.

These folks provide excellent third party testing. We used them for our analysis.

:rofl::rofl: Exxon Mobil is much much more than a "Oil Supplier" to GM. There business partnership extends to product development with such things as the GM oil life monitor system. Bash Mobil 1 all you want and better yet use what you want. I'll continue to use a PROVEN winner that doesn't have to use misleading performance claims.

See above.

Verify all claims yourself. And don't tell them not to use it damet!!! lol

<--Stockholder. :flag:

Good info.. makes sense.. Base stock in synthetics vary..
Mobil-1 is a good choice especially considering the price compared to RL. It's also readily available.. I would use RL oil if I tracked my car often.. M1 otherwise.

:iagree:
Based on the experience others are having, using Mobil 1 will allow my engine to be worn out after only 200,000 miles. Bummer. :D

Castrol is the company that, in a way, took the synthetic base stocks out of synthetic motor oil. Castrol Syntech is a hydroisomerized petroleum product, a so-called Group III oil, that isn't truly synthetic like oils based on Polyalphaolefin or Polyol Ester. In the late 1990s Castrol marketed Syntech as a synthetic oil anyway, because it could equal some of the specs of true synthetics. As I understand it, Mobil challenged Castrol in a BBB-arbitrated forum over this twisting of the term synthetic, but Castrol won, and now many (most?) mid-line synthetic oils are Group III-based. Perhaps there's not much difference in actual use (I don't know for sure), but why pay the same price for a product that arguably isn't as good? Why support the company that had enough contempt for consumers to think we couldn't tell the difference and should pay the same price for a cheaper solution?

If you really want to know what's in your oil, like I do, stick with Amsoil or Redline. At least they're transparent about their oil formulations. As for Edge being 8x better than M1, that's measured by what the high-tech world calls a micro-benchmark. It's sort of like buying a car based on the 0-60 time.

:iagree: This is why Syntec does not have the GM 4718M approval on the bottle.....:thumbs:

:iagree:
I used nothing but Syntec for years, Now I use the Edge, I like it so far!:thumbs:

I have never had any issues using Mobil 1 in my C5 or C6.

What evidence do you have that Mobil pays GM to use their oil?

The fact of the matter is the consumer does not have enough data to make an intelligent decision about what oil to use. The oil spec that a car manufacturer suggests meets the requirement for the needs of that engine. Things like gasket material, aluminum or alloys vs. steel engine components, RPM range, bearing clearances and size, tolerances between parts, operating temps, thermal expansion of engine components, etc. Just because an oil manufacturer says it is 8X better in one catagory that doesn't mean it is a better oil for your application. Use any oil that meets the spec suggested by the manufacturer and you will be fine. The guys with the lab coats have all of the data, you don't.

after watching several teams put Mobil 1 in the Indy Cars at Texas Motorspeedway, I figured it was good enough for my Corvette

Mobil 1 is also the standard with NASCAR.

Let me see if I understand you correctly. If a car is sponsored by Valvoline, or Quaker State, or Pennzoil etc, they dump their oil out of their containers and put in Mobil 1 in their containers so the public, and their sponsors don't know the truth about which oil they are using.

Sure they do. If they do that bit of trickery, how do you know that when a car is sponsored by Mobil1, they don't dump their oil and fill their Mobil1 containers with a competitor's oil.

And several teams used Castrol, maybe some used Shell, etc. Give me a break.

Never had any car engine fail due to the selection of the oil used, in over 40 years of owning and driving cars.

Not saying that you should use vegetable oil, just sayin' . . . .

inb4someonesaystocheckoutbobistheoilguy

I feel a huge sense of security putting in the car what is labeled on the oil cap.

I am quite sure we will see a nuclear meltdown if anything else is used.

If it meets GM 4718M, it's good enough for my C6.
I generally use Mobil 1 in my C6 and my E320, but if I see a good buy on another approved oil I don't mind using it.

I'm sure all the oils are good, but I have never heard of a vette engine blowing up because it used Mobile 1.

Hard to argue with your logic. It's not like you can actually see the difference between oils

Truth of the matter is, as soon as Wal-mart's super cheap Super Tech synthetic shows up on the shelves being 4718M certified, it's just as good as M1 or Castrol or Amsoil. And it meets the powertrain and emissions warranties.

4718M is all that matters to me. nothing less. one thing that 4718M takes in consideration is heat. dyno oils cannot handle it. 4718M can.

I watched it with an open mind and they did a good job beating down Mobil 1.

<snip>

I have 500,000+ miles in Corvettes using Mobil 1. Two of my former four Corvettes (C4s), each with nearly 200,000 miles on them when I sold them, now have in excess of 300,000 miles each. One is living happily in Austin, Texas, the other in Paris, Texas.

Can you imagine? Had I used Castrol those same Vettes would last about 1.6 million miles. Why oh why didn't I use Castrol? :willy:

I have always used Mobil 1 5W-30 as recommended by the manufacturer. However the 5 qt Mobil 1 at $22.00 in Walmart always seems to be out of stock so I am about to try the new Mobil 1 AFE (Advanced Fuel Economy), that comes in 0W-30 viscosity. The Mobil 1 website and the bottle both say that it is 4718M certified and meets or exceeds that standard. The $10 coupon for Mobil 1 is no longer available but there is a $10 rebate on the www.mobiloil.com website available after you take the quiz to see how much they say that you will save per year by switching to the new AFE oil.

[QUOTE=4thC4at60;1571154415]Damn, I hate it when that happens !!!!!! :cheers: :willy:

:iagree::iagree::iagree:

I'm with ya Fred.

0w-30 is the way to go. Same high temp protection as 5w-30 but faster start up lubrication where most wear takes place. Even in say, Miami Beach.

I'll go out on a limb and say before too long 0w-30 will be the factory fill and recommended oil in Vettes.

GM could deny a warranty claim if you are not using at oil that is both 4718M and 5W-30. They've been getting pretty picky about warranty issues recently and who wants to spend the money to fight it out in court.
If you're not under warranty, 'nuther story.

:thumbs:

I like the way Mobil 1 looks. :D

synthetic
 

At what mileage should it be safe to start using synthetics. The rings need to be seated.I have been told??
:cheers:

You can use it from day one, and GM tends to agree since that's been the factory fill in all Vettes since 1992. Rings will still seat perfectly fine even if synthetic oil is used for the initial fill.

I love these oil threads! :D

:iagree:

We havent had a really good squeaking top or Z-51 badge thread in a while either.....:lurk:

I like badges....:D

The Mobil 1 bottles I have read recently do not say they meet the GM 4718M spec, while Castol EDGE, Valvoline Synpower, and Quaker State synthetic do list the spec.
Castrol and Valvoline both claim they provide better wear protection than Mobil 1, and technically Mobil 1 does not even pass the wear test.

Do you guys rebuild your engines after every race too?

Nothing wrong with Mobil 1 but I would never base a decision on what a race team with a relatively unlimited racing budget (compared to a weekend racer) advertises and/or puts in their race cars.

That's a good point. Neither have I. And, my 1994 F-250 went 357k miles before I sold it, and the engine was still very soild with zero oil consumption. (Really wish I still had that ol'rust beater, too!);)

I run Mobil 1 in my vette. I ran Castrol in my track car. I've had no issues with either. In the end, my personal opinion is that in either case we are all gonna be just fine. :D

(But you know what they say about oninions:rofl: )

At one time, only the "regular" M1 in 5W-30 and 10W-30 were approved. The approved list has expanded somewhat but still does not include many of the M1 formulations. They might actually meet the spec but are not listed that way.
Also, I have heard that GM4718M is mostly related to high temperature stability, not wear protection. Can anyone check that?

But as 4thC4at60 posted above, using something better than M1 could keep your engine from being worn out after only 300,000 miles.

I agree if it meets 4718M then it works. But which 4718M to choose? That's personal preference. I'd rather support BP or Shell than ExxonMobil but that is based on some choices (like ExxonMobil not using Double Hull Oil Ships) and other factors.

It's like using Shell, BP, or ExxonMobil Gas.

So my engine will go 1,600,000 miles with the Castrol instead of the 200,000 with Mobil One...:D

What exactly do they say about oninions ????? :rofl:

That's why GM started putting synthetic in Vettes in the first place. I believe M1 was the only synthetic on the market at the time.

I use whatever is onsale. Just so happened to be Mobil 1 last time. 5qt + filter for $19.99, can't beat that anywhere. :thumbs::thumbs::thumbs:

What the... I just paid 45+

Its the California rip off special. Everything costs more out here...

All these oils comparing themselves to Mobil 1 reminds me of all the car owners that like to say their car is faster than a Corvette. :rofl:

Nothing like being so good that you're the yardstick for everyone else.

I would never go as far as saying Mobil 1 is the "yardstick" that others measure up to. Their marketing department has done a fantastic job in making the world believe they are the best synthetic oil out there, but they really aren't.

It's a good oil, but it's far from being the best.

Meh....It did 8 times better in an obscure "wear" test...It doesn't mean it is 8 times better oil imo........I mean it probably more like the 8 times equal the difference between a million and a million one...

I mean really....how good can a oil be when a midget runs around smacking you on the bass with a DIPSTICK Jimmy...;) trying to sell the product.

:iagree: It's all advertising hyp and I'd like to smack that phony Scotsman with a real big stick. :smash: :crazy: :yesnod:

Then why do the other oil companies compare their products to Mobil !??

It was one of the first, if not the first, fully synthetic oil. So obviously it will draw comparisions as it was the "standard" to which all others made their product to.

Because those oil companies know that thanks to Mobil 1's many years in the business, and fantastic saturation of the market, that the driving public perceives them as being the best. Nobody has a higher market share than Mobil 1 worldwide, nobody is even close. So that's why other oil companies are doing this.

not all engine oils are created equal
 

I lived in B.C. and know one of the NASCAR engine builders.
The fact is all nascar teams use Mobil 1 in their engines no matter what their sponsors are.
Castol GTX is the best dinosaurs engine oil, Castol Syntec is NOT synthetic. Mobil 1 is. Think what you want, the fact is Mobil 1 is way better protection is you engine no matter what it's in.
This is not an opinion. It is fact!

No matter what, change your oil once a year at a minimum.

Above for the garage queens.

And, if you haven't, read the oil section in the manual.

:hide:

Sorry you are wrong about ExxonMobil not using double hull ships.That starting changing years ago Just sayin

:iagree::iagree::iagree:

Since were talking oil, does anyone have any experience with the Pennzoil Ultra oil? Now that my GM certified free oil changes are up, I'm switching to Ultra. I've always had great results with Pennzoil in my other cars.

Hello everyone new to the forum,not even sure if I'm doing this right.
It appears there are a lot of knowable people on here.
No one has mention the Hi-Mileage oil that contains more zinc.Since it has more zinc would it be better to use in a Vette regardless of mileage?

Didn't skim through all four pages of this thread, so if this is a dupe I apologize.

I subscribe to industry periodical Lube Report. This is the intro to an article from their most recent report:

"The National Advertising Division urged BP Lubricants USA to rescind a recent commercial that compares BP’s Castrol Edge motor oil to ExxonMobil’s Mobil 1 motor oil, claiming it falsely disparages ExxonMobil and lacks consumer relevance."
:cheers:

I have seen serious testing done on gear oil, (not engine oil) where Royal Purple and Redline synthetics both did worse than Castrol dino (which was the best of the dino oils) and were nowhere near as good as Amsoil, Mobil 1, or Castrol Syntec.

There was a Camaro club that did a test and sent oil off for analysis ever 3000 miles on one of their cars and got 15k miles with Amsoil, and 12K miles with Mobil 1 before the oil tested below requirements. They did have to add a quart over the 12k with Mobil 1 and 2 1/2 quarts with Amsoil. They were not sure why they needed to add oil more often with Amsoil than Mobil 1 in the same car, but felt that was why Amsoil lasted longer.

I also am acquainted with a few motorcycle racers. One who swears by Amsoil but admits it does burn off faster than other oils and actually had one bike that for some reason would burn all the Amsoil out in one race but ran fine on other oils.

To me Amsoil is too expensive and hard to get easily, I stick to Mobil 1 (buy it at Costco) but would have no reservations using Syntec if Mobil 1 was not available.

GM's current recommendation is DEXOS Certified for my 2013. Mobil 1 is DEXOS certified.

BobD

A good job of beating down Mobil 1? How so? I watched it twice, and IMHO, there is little substance to it. How was it tested? What were the testing protocols? It's nothing more than a manufacturers claim against a formidable competitor. If a person for example, uses Mobil 1, and has never had an oil related issue with their vehicle, how do you improve upon that?

5 YEAR OLD THREAD

that automan_1954 decided to resurrect.


Oil threads seem to run constatnly on this site. It sure would be fun if we brought them all up to the front page...

:beatdeadhorse:

Has anyone ever heard of an oil related failure when the filter wasn't clogged up and the oil was clean? Ever?

A few years ago the EPA had oil company's that sell oil for daily drivers to reduce the zinc & some other addictive from their oils ( Not Racing Oils) Mobil 1 Extended Performance 5w-30 has more zinc then regular Mobil 1.Zinc gives you better wear protection,but they said that zinc burns up the Cats??.That oil engineer from Houston should chime in on the thread..He said on the last thread that lasted about a week that The Mobil 1 that comes with the vettes is good as a DD.If you race it then you might want to use a oil with more zinc...:cheers:

I use the Mobil 1 extended performance as it is also Dexos recommended by GM. Should I fear my cats going bad much earlier than they should..?

As most Corvette owners do not put on 10k per year have you tested the various oils from a time stand point (6mths, 1yr, etc)?

I knew a guy that had a 1993 z71 chevy PU truck with a V8 and he had 240,000 miles on it before he sold it!
The oil he used was Walmart oil SuperTech..im convinced that oil is oil!

Mobil ! is a very good oil ,I have taken several cars apart after 200k with no visible wear (I repair cars for a living)..there was a test a couple years ago rating oil on metal wear ,at that time I think mobil 1 was 5th if I remember correctly , Valvoline durablend was 2nd royal purple was first...

Back in the mid 90's Consumer reports did a very extensive test of motor oils in a fleet of NY taxis w GM 3.8 engines. I think it was 60k miles. Mic'd engines at beginning and end. Conclusions were that any oil with the sase stamp on it delivered equivalent performance regardless of price and changing oil at less than mfg recommended intervals was a waste of money(as were most additives) and earth's resources. I started doing that then and when GM came out with oil life monitoring systems started following it's recommendation and using Mobil 1. Had a 2004 Silverado with over 200k on it and running like new when I sold it. I don't think that I will go with the long oil change intervals on my recently acquired GS but that is just because I baby it.

GM uses Mobil 1 because it's the best oil available everywhere in the world.

If you want additional protection with a oil that has more zinc use Mobil 1 0-40. This is what I use..

Depends on how limited the scope of your question is. Many Vette owner's track their cars. In my first season racing in the SCCA T1 class in 2003 with my stock LS6, I seized piston rod bearings #3, and 4. Oil and filter both had well under 500 miles on them. That prompted me to educate myself about oil. I switched from Mobil 1 to AMSOIL and haven't lost an engine to an oil related failure since. On the street - much less severe usage. :cheers:

Since I have not been to this oil thread here goes............. My 1998 Camaro Z28 now has 320,000 miles on it with Mobil1 at every oil change and still runs Great! :thumbs: In your car you can put whatever you want it's your car but for me it's Mobil1. People saying that Mobil1 is crap are just Stupid people. :thumbs: ANY oil changed at the PROPER intervals will be good. :cheers: It's like everything else in life, just depends on your taste.

That is what i use.I have a cam,tune & headers,but i don't have those factory cats..I would not worry about your cats.The EPA is full of it sometimes..:thumbs:

Thanks CN......!!..........:thumbs:

No Sir: All of the Nascar teams Do Not use Mobil 1!! They will not say what they use (Secret).They use very thin oil,All depends on the temp at the track they are ruining at and the distant of the race.Tony Stewart just blew his engine & he runs for Mobil 1??:cheers:

Yes Zinc is bad for Cats. Extra zinc helps reduce wear on metal to metal sliding surfaces so some people recommend in old school flat tappet cam engines.

Seeing as virtually all newer engines have roller rockers and modern oils are much better at protecting roller and ball bearing surfaces than older oils, on modern cars the extra zinc is not critical. And ZDP burns to ash which is not good for the life of the oil as it causes oxidation.

"The new API SM oils contain about the same percentage of ZDP as the oils that solved the camshaft scuffing and wear issues back in the 1950s. They do contain less ZDP than the oils that solved the oil thickening issues in the 1960s, but that is because they now contain high levels of ash less antioxidants that were not commercially available in the 1960s." Bob Olree of GMPT Fuels and lubes posted on Bob's the oil guy forum.

"The big issue is when breaking a flat tappet engine in, so if you are rebuilding an older engine you really need to use something like a racing oil where there’s a higher level of phosphorous in it. And racing oils, can still be the 1,200 parts-per-million and get a good break in on the engine. After that they will run fine at the current 800 parts-per-million." Tom Smith - technical director of Valvoline from Motor Trend interview.

:iagree::thumbs:

Nothing like digging up a 5 year old thread.

The Idea that oil needs more zinc is left over from issues in technology 60 years ago. That means a 5 year old oil thread is pretty current. :D

:iagree:

:iagree:
S -

i just started using edge in my ford im. No problems yet. i just want to put the best oil I can in. I'm still trying to figure out if they are both just as good or if one is better and why..

Motor oil is one of the most heated topics.

This thread is almost 8 yr old... :toetap::toetap::toetap:

Put a fork in this - I think it is overcooked.

Castrol Edge vs. Mobil 1
 

Interesting Posts. I would like to use the best, but only if it is clearly better than Mobil 1. Bought a C4 1995 Vette in pristine condition last month. Previous owner, one owner, ONLY used Mobil 1 10-30...64,000 miles, and Carfax shows only 7,000 miles in last 9 years. Valve covers and heads look CLEAN, no varnish, gronk, crud, hardened crap...they look brand new, valve springs, guides, cover insides where they drip, after key is shot off. Can Castrol Edge do this? Just tell me.

Some of the research I read, I cannot use, as I will be changing every 2 months or 2000 miles, and the filter every 4 months or 4000 miles. We are talking $12 a month for Mobil 1 and $14 a month for Castrol Edge Titanium. Walmart prices. I can crawl under the car 6 times a year and cover THAT cost.

How an oil is at 10,000 miles means nothing to me. I would never BE in that scenario.

Also, does Titanium electroplate the catalytic converter like the Zinc additives? Leaded gas did the same thing in 1975 in one tankful. Nightmare.

Bottom line. Is Castrol Edge gonna(1) keep those valve covers clean, (2)not wreck my cat, and yet(3) have less wear than Mobil 1 ?????? It is only $5 more for 5qts at Walmart.

Like waxes, oil companies don't have any big secrets. Everything is knowable. If company "A" has a superior item, everyone else will analyze it and try to copy it.

Brand "X" may be better than brand "Y" at something, but will sacrifice something elsewhere. There is no free lunch.

As for keeping an engine innards clean, the brand of oil doesn't really matter. What does matter is avoiding short trips and always bringing the engine up to operating temp. And if not, then one should change the oil more often than would otherwise be necessary.
