My husband has been using this oil on our Ford F350 for a while now and it’s the only one he likes. The engine runs smooth and quiet every time. We’ve had no issues at all and the quality is consistent. Definitely our go-to oil.

Been putting this in my 2020 F-350 6.7 diesel and it has been great! I tow most days for work so I knew I needed something heavy duty and the truck runs nice and smooth on this oil!

This is the least expensive synthetic oil available that meets the specs for my metric bike (2012 Kawasaki Concours). I just started using Rotella T6 about 2300 miles ago due to not being able to find any specifically marketed synthetic bike oil for less than $10/qt. Apparently lots of folks have been using this oil as a substitute cycle oil for years with mixed results across the board from 'It's awesome' to 'It destroyed my engine/clutch'. My experience so far has been great with no noticeable difference between using this oil and using Valvoline 4T Stroke full synthetic. The shifting just after the change is smooth then becomes a little notchy after about 400 miles just like the Valvoline had in the past (the bike has exhibited this since new, now approaching 40k miles with 11 oil changes and the original clutch still chugging away). Sam's was selling this 3 gallon case for $forty-six seventy when taking off $fifteen for a special they had. At only $three eighty nine a quart I was in for enough to outlast this bikes foreseeable service with me.

t This oil stays clear and clean in my 2012 Ram 2500 6.7l diesel longer than most other brands. My Ram has over 300k miles and still runs great. I change my oil every 5-6k miles along with the fuel filter and could surely could go longer between changes based on the way the oil looks.

Good oil for a Cummins engine.

Best price for this product

The price went up from 3 months ago. That was not good!

It was exactly what I was looking for at a great price.

Excellent quality for our F-350 6.0L

Best oil for heavy duty trucks that put in many miles , drive 10000 miles a month with my F250
