This oil works hard to protect my 24-year-old 7.3 liter Ford diesel. Almost 350,000 miles and still going strong.

This is one of the best oils you can run in a power stroke. The one gallon containers make filling the engine easy.

[This review was collected as part of a promotion.] I have always used this oil for my diesel truck. I will use it again.

[This review was collected as part of a promotion.] Hard to rate when shipment is delayed and no reason or expected ship date is provided.

First make sure you are ordering it directly from wally, avoid issues. Great on my 2.0l turbocharged GTI @110,000 miles.

In my opinion this oil is the best quality oil. Been putting that in my truck and it runs so smooth.
