The only issue we found with this was that it only comes in one size at the store. We needed one extra quart and had to get another whole one this size.

Great oil for turbo gasoline cars as well!

Rotella T6 may be listed as diesel oil, however, it is good stuff and runs great in turbo Subaru applications. I have used it for years in WRXs and STis. Always looks pretty good after 3.5k of spirited driving.

Great buy

Price is way lower than any other store plus free shipping to ure home is a great way to get the products instead of heading to the store and find out that product is not available in shelves

Best oil...BEST value at WALMART!!!

This oil was recently added to the approved list for RAM Ecodiesel. It is half the price of their previously approved oils. Order it for pickup on Walmart.com to save an additional $3 on 3 gallons. Shell and Walmart, thanks for taking care of us!

Rotella Synthetic is very good for the price.

I use the product in my F-150 gas engine truck and am very pleased. Don't let the "Diesel Engine" on the front fool you, my auto care specialist said it works fine in gasoline engines as well.

great performing synthetic diesel oil

I like the fact that Walmart stocks Rotella T6 5w40. I really like the performance of this full synthetic oil for my Ford F350. I would like to see better cost savings if possible but overall satisfied by offering.

[This review was collected as part of a promotion.] Using product for many years-exceeds specs of oil used by Ford dealers when doing oil changes. Consistently rated in top 1 or 2 reasonably priced oils for diesel engines.

in different applications, both petrol and diesel, this oil provides turbocharged engines with sufficient protection. has that trademark shell smell, but that's alright.
