I want to start using it in my 2000 F350 Diesel. I was just wondering which one is the best and the price of each.

If you use Mobil get Delvac 1 or Mobil 1 Truck & SUV. Mobil 1 isn't formulated for diesel application. Use an oil with CH-4 or CI-4 rating. I use Rotella T Synthetic. Wal Mart carries a good selection of oils, including Shell and Mobil products, at good prices. They also carry Motorcraft oil filters.

I was told to use the 10-40 grade oil. I used the Rotella regular in my new van with 6.0 for the first oil change. When I called the dealership and was told how much they wanted, I did it myself. A little over $40. with filter. They wanted $89.95 + tax. Yeh, Right.

The Rotella syn 10w40 will be just fine. Has been used by many heavy hualers for years.

I ran Mobil Delvac1 synthetic in my tractor. Cat 3406E 475 hp. Gained about 8% fuel economy, extended the drain intervals to nearly 100,000 miles, and used less oil in the meantime.

FYI-I haven't been able to find anything to the contrary, but Rotella 10w-40 synthetic is a synthetic blend motor oil not a full synthetic. Rotella T Full Synthetic 5w-40, in the blue jug, is the one to use.
