trying it for the 1st time, its the least expensive place to buy it from ,belive me I did my homework. Thanks

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.

Hard to rate it while its in the jug. Other reviewers love it. So I give it a three , we will se how it works in my duramax 6.6

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

I buy this diesel oil for old flat tappet gasoline engines. Diesel oil still has zinc and other additives that old gas engines need.

Great oil at great price. Use it in the tractors and with lesser cost tend to change it out more frequently.

Good product for a good price Glad my Sam’s started stocking this was having to drive 50 miles to a club that stocked it

I use this oil in about 4 diesel engines and have not had any problems. And a lot cheaper then the other oils.
