Hey everyone,

So my car was at about 14K and i needed an oil change so i decided that I wanted to do synthetic. I took it to the dealership and to my surprise they actually had Mobile 1 as their synthetic. (Mobile 1 is by far the best synthetic oil out there).
Anyway, I have a quick question. I know that synthetic oil lasts longer than normal oil because it doesnt break down nearly as fast. But am i correct when I guess that the oil still needs to be changed around 3000 or so because the oil can still get DIRTY? Thanks everyone in advance for your info.

:multiples :dj: <---- its like a friggin party in my thread, thats badass

BUZZZZZZZZZZZZZZZ Wrong

Mobile 1 is not the best, if you want a true synthetic then go with Amsoil.

Synthetic change intervals can be prolonged. I change mine at 5,000 miles

Synthetic is not advised for high mileage vehicles, which, clean out the gunk deposited by dino oil and can develop new leaks. Its not that synthetic makes the leaks, just cleans out the sludge and can go into areas regular oils cannot.

Great. there goes that idea. LOL so what do you recommend for an older engine?

Im not saying that you cant use synthetic, just be prepared of the possibility of new leaks. If you want to go the old route, just regular 3k oil changes and normal interval maintenance.

Oh, I think I understand what you were saying about the syn going places oil can't. A place that would normally not leak normal oil may leak syn due to it is made to go places that normal oil can't. Smaller molecules and such right? That might explain why my engine is leaking oil all over the place. It is basically being fixed now but I think I will stick with the normal oil from now on. Any preferences you recommend?

Not smaller molecules, just more uniform and equal in size. As far with preferences, its dependent on the person. Some swear on Castrol GTX and others penzoil. Just make sure it follows API (american petroleum institute) guidelines in regards to detergents, etc.

So what harm is there if you go back to regular from synthetic?

Set aside from losing the benefits of synthetic oil, nothing.
