ANST will not reply to my inquiries in regards to a missing item they sold me.

It is oil. Motor oil. It works and was delivered on time.

[This review was collected as part of a promotion.] Solid, lowercosting without sacrificing price!

Good product, I use it frequently.

other than took a week longer to arrive got a better deal then anywhere in my town

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

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've been using Rotella T4 for a long time in my semi truck engine. Newer had any problems. When you change the oil in the engine you can tell that it's Rotella, because it has specific scent no other oil has. Great product.

I use this oil in several vehicles, especially my older ones. It has more zinc than the newer oils which is needed for flat tappet engines. You also can't beat the price if you use a lot of oil.
