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.

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...

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!

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

Recommended oil for my 08 F250 Diesel. Seems to run smoother

Great Oil

Use Rotella in all my vehicles! Toyota Echo now has over 347 thousand miles and going strong!

Works great in my motorcycle!

I have been using this oil in my 1998 Honda F6 Valkyrie Tourer for 6 years now, and have had no issues with clutch operation. Even at full throttle with the big 6 cylinder engine, no clutch slippage. Also, the notorious Valkyrie top gear whine was a lot quieter immediately after the first oil change. It's also priced a lot cheaper than the competing oils, a nice added bonus. I don't hesitate to change the oil when I should, when the price is about half of other high end or OEM oils. It's ...

Use in everything!

I use Rotella T6 in almost everything I own and have owned in the past. Its in my Toyota 4Runner, Its in my sons Kawasaki KX65 two-stroke, Its in my my Honda CRF450R, and also my CRF150R, Its in my lawnmower, and Its in my 4-stroke weed eater. It also does not cause any clutch slippage in wet clutches. I don't use it in my Tundra and Honda Odyssey because its not the right viscosity but I wish I could. I've used T6 exclusively for years in all my engines and never had a problem or any signs of w...

My F250 6.0 loves this oil!

Great running from an idle to pulling this oil has my 6.0 smiling all the time!

Great oil

I have 345000 on my 2001 Jetta and have been using rotella T6 sense I have owned it with 20000
