Royal purple

[philbillyvette]

Anyone using Royal Purple in the LS1? PROs and CONS? Is it worth the .50 more per quart than the Mobil 1 5W/30. Getting close to doing an oil change on my C5 and just curious.

I used Royal Purple in my LS1.It is big$$$Did I notice a change-no.The oil appeared thiner than Mobil 1.I'm just going to use Mobil 1 and be done with it their is no real reason to try different brands-for what reason?Just keep it full and clean.

I kinda of consider it a waste of money .But in my case I don't drive very hard and I believe thats the case for the majority of owners.I've never had an engine fail because of lubrication using Mobil 1.

But if it makes a person feel really good ,why not

I agree vette boy!Just use Mobil1 and be done.Two BIG corvette debates-oil brands and wax brands go figure.:cool

Be it Mobil 1, Royal Purple or other synthetic oil, you are better over the long haul to use a 10W30 rather than a 5W30.

OK I may be setting myself up, but isn't 5W30 recommended by GM? Would you mind explaining the 10W30?

Thanks

Thanks Hib, never gave it much thought before.

Thanks for all the input on this subject. I will go with the Mobil 1, and will take into consideration the 10W30 over the 5W30 for the longevity issues.

Royal Purple 5/20

A local major auto chain advised me that 5/20 was best for the heat of Phoenix. I am beginning to doubt this. Any thoughts?

I don't think I'd do 5w20 in Arizona......10w30 would be a better choice I think.

DO NOT use a 5W20 in an LS1...especially in very hot weather.

My choice in oil is Gibbs Driven LS30 5W30. It's a premium synthetic and a step above Mobil 1.

When Gibbs lost his Shell sponsorship, camshaft failures increased.
