The OIL thread.

[Durtie]

What kind of car and mileage? there's really no way to tell you a solid answer without a tests, i can make an assumption... but the only way to know is a test. Lets say you had a 2010 Honda accord.... it would be safe to assume your Honda engine is running pristine and not leaking any coolant or fuel into your oil, knowing that your oil is not contaminated, i could confidently say yes, your amsoil would go 10k miles easily. Flip that script and use a 98 Cavalier as your example vehicle.... fuel could pass the rings, may have a small coolant leak ect ect that can contaminate the oil. These are all things that a $35 UOA can tell you in specific detail. Based on the information you got back from the UOA, you could then decide what oil is best for you. Lets say your car had elevated fuel levels in the oil shortening it's lifespan, then you might decide that a cheaper oil and more frequent changes was a better route for you.

I have a 2000 Toyota Celica GTS. It runs great, no leaks. 112000 miles on it. I drive my Talon around every where so I only put about 3000 miles on it in those ten months just joy riding. So I guess I'm good. I'll do more research next time just in case.

"Leaks" wont be something you can see. I'm talking about fuel seeping past rings, pinholes in gaskets allowing small amounts of water into the oil. The outside of your engine could be spotless. My guess is that you're just fine goin 5-7k on a 00 celica, if you want to know for sure, test is the only way.
