This type of oil is required for my diesel engine. There are other brands available, but this is a top name brand and it's readily available at many places. Walmart and Tractor Supply usually have the best prices for this brand.

I bought this 5w40 oil for my motorcycle. It's one of the best synthetic motor oils that I've ever used!!! Runs smooth and is especially ideal for cold winter starts. Would recommend buying this oil over Mobil 1 0w40.

I've been using this oil in all of my vehicles for years and recommend it highly. Currently, I'm driving a 2016 Ram 3500 with 120K miles and it runs like a champ.

[This review was collected as part of a promotion.] Recently began using this product for my vehicle since it significantly improves the engine. The discount Walmart provided was exceptionally amazing since it is pricey.

Great price!
