My diesel likes it year round

This diesel oil has the Ford spec required for my vehicle. Full synthetic.

This oil is terrific for a wide variety of engines and conditions.

works well for my 1992 mazda miata

I trust no other oil for my 04 Dodge Cummins. 280,000 miles strong!

Most diesel truck owners soon to go for this oil. Walmart has a good price! The free delivery is nice!

[This review was collected as part of a promotion.] It was exactly what I was looking for at a great price.

This is the only oil I use for my F250. It's got high heat tolerance and resistance to shearing. Sam's Club also has the best price.

[This review was collected as part of a promotion.] The price went up from 3 months ago. That was not good!

Would be nice to have a five quart jug not a four quart because I have to buy an extra quart instead of only having to buy the gallon size. Make a gallon and one quart size would make it so easier on everybody
