Just curious.... I seam to have a reoccurring issue that is either Oil or cam related. I'm not quite ready to let the cat of the bag on this until I get some CSi reports back on the parts.

any input from past users of royal purple would be great.

I don't happen to use RP oils because they refuse to specify the HTHS number. This is exactly the number on needs to judge if any particular motor oil is acceptable for track use (i.e. when really hot).

bowtiguy

Interesting. MFG of said part suspects oil issues. when I told him that I used RP, he replied.... which is great because I have it in my tranny and rear end too.

no gauling of related parts that come into contact with this part, so the search is on.

I was going to put Royal Purple in my tranny. Heard it was the best thing next to sliced bread....

Sorry about your issues. To me it is another example of the "boutique" oils that are more hype than substance. There is absolutely nothing wrong with the factory fill Mobil 1 5W 30. Why spend more money and risk problems. I don't like it in trannys or rear ends either.

Good luck with your car

I have always had good luck with RP. I did however switch to all Amsoil fluids in my Hummer. I may switch over to Amsoil in the Z this summer as well and see if I can tell a difference.

Good luck, I guess all those auto manufacturers don't know anything.

Well don't leave us in suspense man, tell us what happened.

Did your motor pop?

RP as a "boutique" oil advertises well and has many fans, but didn't compare well to the other fluids in these tests (even if you discount the AMSOIL these are still interesting reads):
AMSOIL Motorcycle Oil “White Paper” (1 MB pdf file)
AMSOIL Gear Lube “White Paper” (2 MB pdf file)

Neither are engine oil (or tranny fluid for the poster above), but I suspect the results would be similar.

I'm leaning towards Joe Gibbs ( which I use for break in oil), Mobile 1, or Redline. Quite honestly, I figured they were all the same one way or the other. Mobile 1 definately cheaper than RP. I actually thought it was just internet forum blah blah blah....initially.

(Edit: new information) Motor did not pop....Its just fine. Just getting premature wear on valvetrane. I'm waiting for a reply on the parts from the MFG before I share my experiences with everyone. I've talked with the supplier of the heads/cam, my engine builder and the rocker company.

My goal is some evidence based research that others ( including me) can benifit from. I've been the guinea <sp> pig on several aftermarket LS7 products on my past motor and I'm hoping others do not have to go through the same.

I don't want to come off as a finger pointer by jumping to conclusions. I just want a product combination that is reliable for a 80% street 20% track LS7 making 57x/53x at the wheels.That maintenance is a bit too excesive for a hydraulic roller motor IMHO.

when I have more info I'll make a more complete post.

In the meantime I'm riding my titanium IBIS road bike to and from work 26 miles round trip. I needed to work off the beer gut anyhow.

I talked to "Bob the Oil Guy" last year and he said RP was fine in the trans and diff, but he would never recommend it in the motor.

Why?

bowtiguy

Oil does not seem to be the cause according to the Rocker MFG. I'm having some valve train parts tested on monday while my heads are at the machine shop getting a once over before they go back on.

yes my friends its down to the short block.

Good news is I caught it before anything major happened. magnet on the Peterson oil tank and drysump lines came up clean. Filter caught it all.

I do have one thing to say. I would NEVER do a C6Z cam swap for 50-60 Hp. you people are crazy

Mine had to come out, pic's to follow soon.

vetteship

GM already did the R&D, I use what they recommend. Good luck with solving your issue.

Chit, that just great, I just switched over to the Royal Purple 2 weeks ago in my engine. Now I feel like I should switch back to Mobil 1 and leave well enough alone!

Uncle Meat

RP is a little too gimmicky for me. Getting owned by BP in that advertising lawsuit was the nail in the coffin. I wouldn't run RP in my lawnmower.

I spent big bucks to get RPM L-5 trans and diff...they told me to use RP in both, so that's what I've done, assuming they should know what they're talking about. However, I still run M1 in the engine.

Cheers, Paul.

Sounds like you're definitely approaching this the right way; step by step.

Keep us posted on what you learn.

Sorry to see you have to go thru this. In the end, perhaps we'll all benefit by having more knowledge.

bowtiguy

Thats the goal. I stopped pointing fingers a long time ago. My goal is to figure out why things went south and make sure it doesn't happen again. If I can help some fellow CF members out in the process, all the better.
