would you believe - None! The first owner ran nothing but Amsoil and sent the oil out to get checked periodically for particles. I put the last 20,000 on the motor from 7/06 - today. The previous owner put 10,000 from 2000 7/06 and the other 250,000 was put on by owner number 1.
Gear #2 did go last year so I switched to an LT85.
I am running Mobil one so hopefully I can keep the motor going.
What is the typically expectation on these (3.9L) for mileage?
