Not a full gallon. These jugs are short. We had to use additional jugs to fill truck. Not sure why. Multiple boxes checked and same thing in all.

What's there to say I use Rotella for my diesel truck. They had it on sale and delivered it free and quick.

Ordering was easy and delivery was prompt with the cases in good shape (and best of all the delivery was free!).

Been using this product in my 7.3 diesel for 250,000 miles. Engine is still toght and does not produce excess smoke.

Great transaction. Very good & very easy to do business with. It would be better if shipped on a pallet for ease of unloading.

I have used Rotella in our large trucks and farm tractors for many years. The product delivers on quality and price was great too.

We have been using this oil in our Cummins diesels for the last 15 years and this the best price we have found .

I use this oil, they had it online but not in the store, I bought it. Took a while to get here so order well before you need it.

I drive a 1993 Dodge D250 with way over 300,000 miles. Engine is working as well as it did when new. Starts in 1-2 seconds.

Rotella T4 for heavy duty semi truck. I personally love this oil for my engine. The price for it could be less, but the world that we are living in today.
