I am gettting my tune up next Saturday and I was speaking with Kennginn on what to get. I made a suggestion on getting some synthetic oil and he said no, get the high mileage oil. I didnt think it was a problem geting synthetic but he mention, by me having high mileage and not knowing how the car was cared for, you might want to start with high mileage. I said ok. But I love synthetic. I don't want to be hard headed or anything but whats your facts?

I run Valvoline Max Life in the LSS. It seems good and doesn't tarnish at all.

most definatally do not run synthetic in that motor, it most likely will start leaking, i know mine did at 153K. With yours I would run 10w30 Valvoline or equivilant. Non synthetic oil will take good care of your motor if you change it regularly. I used Quaker state in mine actually, no problems till i changed over to mobil 1 higher mileage. That stuff is to expensive to leak out all over! lol.

ok, since you mentioned mobil one, and i am used to that stuff, thats what I will use.

Hes telling you not to run Mobil 1 because it is synthetic ... synthetic oill in a high MI. car can sometimes, but not always leak out of the gaskets and he doesnt whant you to waste your money

oops. i will check out the quaker state then.

If the car has had synthetic its whole life, then it would be fine, I would think. Other than that, maybe switch to high milage oil.

My GP used synthetic for it'* whole 90,000 mile life. It still uses it with no leaks.

You are better off with the cheapest 10W30 you can find, assuming you change it more often than necessary - at least every 2500 miles or so. Better not to use full synthetic on any higher mileage car you could use a synthetic blend though (often marketed toward higher milage cars).

synthetic blend won't leak?

i have a freind who bought a honda accord with 295k and when he bought he started use sythentic and he has no problems with the motor leaking or burning any oil now its got 308k and still going strong? you can stereotype that every motor is going to leak or whatever if changed over to sythentic heres a example that nothing happened??

i run Vavoline MAx life 10-30
second choice is castrol gtx
