I have used this oil for many years and I have never had problems with my engine internally and it has passed a million miles.

I used it in a 7.3 for years ... and now in a 3.0 ... no problems, no consumption issues ... works well in motorcycle engines too.

Great oil for heavy equipment, it's my favorite brand. WalMart has sales periodically, so it makes a great oil a great deal!

[This review was collected as part of a promotion.] For a semi synthetic, WM have the best price on a quality oil.

The contain is my biggest issue, most gallon jugs are standard sized and fit the opening on the engine, these don't, which causes spillage.

[This review was collected as part of a promotion.] Very good oil at a very good price for our fleet.

[This review was collected as part of a promotion.] Its the Beat product for my truck and you can't beat the price..

This is the only oil I will use in my diesel engine. My engine has 390000 miles on it and still going strong with the help of this quality oil
