JoeFromPA Posted July 18, 2008 Share Posted July 18, 2008 Andreu - I'll try to give you the straight of it: Synthetic oils have very small, uniform molecules. This allows them to flow faster and fit through smaller spaces better than "natural" (or dino) oil, which tends to be heterogenuos and have larger and smaller oil molecules. The effect of this is that if you HAVE a leak, synthetic will tend to leak out faster than dino oil. If you don't have a leak, you will reap the benefits of synthetic oil. If you switch to synthetic and suddenly notice a leak, it's because you already had a bad seal and the synthetic oil allowed more to leak out. Hope that helps.

f1anatic Posted July 18, 2008 Share Posted July 18, 2008 I think you should search the site a bit as there are many threads on the subject. And I think you should use synthetic. Link to comment Share on other sites More sharing options...

SilverLeg Posted July 18, 2008 Share Posted July 18, 2008 Sometimes synthetic oil causes leaks, which then can effect the intercooler....which should never be cleaned with soap Link to comment Share on other sites More sharing options...

alain_desforges Posted July 18, 2008 Share Posted July 18, 2008 Synthetic oils were invented with the advent of the turbine engine. Regular (dino) oils couldn't handle the high operating temperatures and would break down, hence the need for a better, longer lasting oil... nuff said....

I took my car for an oil change the other week and the dude said the computer says to only use synthetic for the GT. I think he was just trying to convince me to spend more money If you don't vote Trump, out, you're a bigot who hates america. Link to comment Share on other sites More sharing options...

DrCloud Posted July 18, 2008 Share Posted July 18, 2008 I took my car for an oil change the other week and the dude said the computer says to only use synthetic for the GT. When I picked up my LGT.B from the dealer, their service advisor told me, in no uncertain terms, that Mobil 1 would "melt my engine." (Truly, he said that.) Actually, he did me a favor: now I know never, ever to go back there for anything service-related. But I guess that's consistent with Mobil 1's being the devil, at least...

Synthetic oil has a better viscosity range than dino oil making it more flexible. The big problem with oil selection is not the oil itself but the people selecting the wrong grade and quality of oil for their vehicles and then blaming the oil.
