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.

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.

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

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.

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

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.

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

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
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!

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.

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.
