This is what you want to use in a 6.0 Ford or any other diesel for that matter. Very good for cold weather use.

[This review was collected as part of a promotion.] This oil was available and less expensive then my wholesale supplier.

I have used rotella since the 1980s . Now it’s full synthetic and got a 500000 mile protection on it

Currently the best value for your money. Keeps that 500,000 shell diesel engine warranty up to date.

You cant goYou cant go wrong with us full synthetic oil and especially for the price theyre selling it at.

Great oil for lower temperatures. The only oil I trust with extended drain intervals on my 6.7 cummins. 513k miles, all original motor.

Best oil out there for a diesel engine. I have used it since it came on the market and have had zero complaints.

This oil is generally hard to find and, at times very expensive. Seems its always in stock when i need it at a great price.
