My wife and I are boaters and each fall we change the oil in our Diesel engines and the generator. Each year we need 10 gallons and purchasing 4 of these and having the delivered to the store made it very easy for us. Thanks Walmart

I've used Rotella T4 15-40 in my 1300cc liquid cooled motorcycle for years because of its heat hadling capabilities and wear resistance. Very pleased with the results and does not compromise the clutch action.

Been using in my tractor trailers for over 40 years and over 5 million miles. Never had an oil related failure. There are newer and more expensive oils o in t there, but it’s hard to argue with success…

Who picked the 2.5 gallon container size... obviously they don’t change their own oil. My truck requires 13 quarts... normally 3 gallons and 1 quart. Stupid

Use this in my '06 Duramax LBZ/ my air cooled 4 stroke engines(lawnmowers/generators), and all of my 4 stroke dirt bikes. Superior to any non-synthetic oil I have ever used. Recommended to all my friends/acquaintances.

This is the only oil I have run in my 2001 Ford F-250 Superduty 7.3 diesel. I now have 248K miles on it and it runs like it was new. I would never try any other oil..

I have been using Shell Rotella 15w-40 for my diesels for about 10 years now, and I am very satisfied with the performance of this oil. I have had no problems with it at all!

It's a good buy!

Good price
