from regular old fashioned dino oil to a fully synthetic oil. yesterday i did my oil (700 miles overdue...oops) and switched from mobile 1 5000 to the valvoline fully synthetic stuff with the lucas oil stabilizer. that lucas stuff seems to have nearly stopped any seepage i had before, wouldnt notice the difference while driving though haha. anyways, it just made me feel better knowing i gave my baby the best!

 

Good for you.[sm=smiley20.gif]

 

Correct me if I'm wrong, but isn't Mobil 1 a full synthetic oil? I hope so anyway, because I've always used Mobil 1 and changed it at the intervals usually set for synthetic oil.

Yes, doesnt say if it fully syn or not. Although i guess if it were a blend it would say "synthetic blend"
