Synthetic oil switch from regular at 50K
>> we doubt the dealer has used the exact same oil every change.
I want to switch to synthetic at 50K and change it myself now. Anyone think it's a bad idea? wear patterns? horror stories? risk of leaks at seals? I know I should have done it when still under warranty.. .
I drive the LS1 2002 TA pretty hard. This might make it better.
I appreciate the input. Goodbye Dealer !!!!
