Royal Purple Street Synthetic Motor Oil - SAE 15w40, Quart Bottle, Pack of 12 Review
For the discount price I bought it at (.00) it was cheaper than buying 5 gallon containers, but not as convenient to fill my 12 quart diesel system. Seems to help truck run cooler and better performance than normal oil.
