I had an interesting conversation at my dealer today. I brought my 2004 Sebring conv. in at 6,000 miles for its second oil change. (Quaker State, synthetic) I told the service writer that I never have used syntheticbefore but I heard it may give the 2.7 engine a better chance at long life. The service writer said, "Yeah, it helps but don't plan on keeping the car past the warantee period, not with the 2.7 engine"
Gives you a lot of confidence, doesn't it?
