Mobil Super High Mileage Synthetic Blend Motor Oil 5W-30, 1 Quart

I'm the second owner but Mobil 1 was used since day one. Purchased it in '05 with 100,000 on it. Just turned 300,000. Only major engine repair was an intake manifold at 150,000. Usual plugs, coils, brakes and other maintenance items. Original motor and tranny. Oil changes at regular intervals around 5-7000 miles. This is my personal & work vehicle that I use every day. Tow my boat or my dump trailer with ease. I feel that Mobil 1 played a large part in expanding the life of this engine. Even my mechanic can't believe that it just keeps going. Thanks for a great product.

Have been using this oil for a year now in a 1997 Ford F250 service truck I puchased at auction. The truck is a former county service vehicle with the 4.6 V8 that had 128000 miles when purchased and has had a hard life. The county garage uses conventional oil in it's older vehicles, so I wanted to stay with a conventional oil, but use something with a little more protection. This oil seemed perfect for the job. I've put 12000 miles on it so far using only this oil. The oil consumption has been very acceptable considering the age and miles already on the truck. Even in the winter at 10 below zero, the oil pressure comes up quickly on a cold start. I generally change oil at around 5000 miles. The old oil looks good and feels right, with no burnt smell. I could probably safely up my miles between changes. So far this oil has been working very well for me.
