Cause the nearest dealer is 45 min away. BTW, I keep all my receipts & I write the mileage down on the receipts.

 

Actually, they remove oil pan and do inspection. They only replace engine if sezied. They did a clean out on the crankcase. new gaskets , ect.. and your warrenty goes to 8 yrs with unlimited milage. You recive a list of acceptable motor oils and the intervals to keep under warrenty,, and by the way wehn I purchased car new I also purchased the extended warrenty.. what a joke that is.......[:@]

 

The dealers use Castrol Syntec 5W-40. It is just as good as Mobil 1 0W-40.
