Working on 1,000,000 miles. 2 more years.

Forgot to mention, a lot of oil changes (Valvoline PB2000 only), filters, light bulbs and wiper blades. Engine, Trans and rear end are treated every 4 oil change with MotorKote. Look it up, it's an unbelievable hyper lubricant.

That's incredible. What do you do to put that many miles on it? What's your oil change interval?
