Ratings & Reviews for Shell Rotella Rotella T6 15W40 Synthetic Diesel Engine Oil 1 Gallon

Works great in pretty much any engine!

I love Rotella T6 5w40! We put it in all of our cars and since it meets JASO-MA ratings, we put it in all of our ATV's as well!

Just upgraded from using the T4 to the T6. want a lil better quality in my engine

Great oil

I switched to Rotella 2 years ago and the results are clearly visible. Used in motocross bikes clutches last longer and trans gears show much less wear. Really good product.

Great oil

I have used Quaker State in my vehicles for over 40 years. Never had any problems with using it putting hundreds of thousands of miles on different vehicles

The best

I have been running shell oil since I bought my duramax in 2002, the truck has been used for construction in northern Alberta in the oilfield it’s entire life. Big trailers, -30C morning starts, working lots of hours , Shell’s fluids have never let me down. The truck has 800000 km- 12000 engine hours on it and the engine runs as good as it did the day I drove it off the lot. Doesn’t use any oil at all from oil change to oil change. I Switched to t6 at 400000km and run the 5w40 year round. I chan...

Only oil I use

Always keeps my cars running great... 5 cars in the family, only oil I will ever use.

5 Stars!!!

This is the only oil I will use in my 2014 GMC 2500 Diesel! We pull a 37ft 5th wheel and this make one less thing to ever worry about!

ADVANCE DURABILITY 5W 20 AND 10W 40

I BOUGHT TU VISCOSITY GRADES AND I NEED TO KNOW IF THESE OIL ARE MINERAL OILS, BLEND SYNTHETIC OILS AND FULL SYNTHETIC OILS. CAN YOU GIVE ME A ANSWER?

Awesome in my 2011 Subaru WRX

My turbo loves this stuff. It blows unleaded synthetics out of the water.

Works great in Ram 1500 Diesel

I have been using this in my 3.0L EcoDiesel since the first oil change; better oil pressure than the OEM oil, and Chrysler has since made this the recommended oil for that engine. 10K mile oil change intervals, doesn't use a drop. Starts fine in cold weather too (only down to -10F here in Texas...). PS: I cannot imagine why someone would use a Diesel oil in a motorcycle.

Very Good oil

Been using in my VW Touareg since I bought it. One a few oils VW approves of. Not any issues.

Best Diesel Oil

I've used this in my Duramax pickup since 2004. I has helped keep my engine like new. I bought a V-4 Honda motorcycle four years ago and was pleased that the ST Owners forum recommended this same oil. After 50,000 miles in less than four years my ST performs like new.

Worth the switch to full synthetic

I have a 2009 Silverado 3500HD. This is the first time I've used Full Synthetic during an oil change. The Duramax loves it.

Keeps my engines running

I run Rotella T6 5w-40 in my 2011 Ram 2500 Cummins, and in my 2002 Audi A4 1.8t. The 1.8t is notorious for sludge issues, but Rotella has kept mine clean as can be.

Excellent

I use it in everything including a VW diesel that is only supposed to use Castrol. I haven't had any engine problems in this car for over 200,000 km.

Excellent MPG and great protection

I use it on my 2015 Eco-diesel with 84,000 miles. The oil gives me excellent MPG, I've gotten almost 34mpg on the highway 28-29 on the street. But the best part is getting money back and earning points!

Fantastic old friend

Been using Rotella synthetic for years used in cars trucks and motorcycles since new 87 kawasaki concours 1000 60,000 miles + 93 Pontiac Bonneville into 130,000 Yamaha V-Max 19,000 miles, 2009 Chevrolet Avalanche 202,000 miles, also used it in Kaw.Concours 1400 and Piaggio BV250 Scooter, ULTIMATE PROTECTION!!!

Rotella T6 F-250
