Ratings & Reviews for Rotella Shell 5W40 Syn Gal Diesel Motor Oil - 1 Gallon - For High Mileage & Diesel Engines

Diesel loves it

Good

Great motorcycle oil.

I have ran this for years in my Honda Goldwing. Makes transmission shift smoother than Honda brand oil.

Best in the Business

Shell Rotella T6 is the best heavy duty oil on the market. Price point for superior protection attracted my attention back in 2015. I have been through three 6.6L Duramax vehicles since and not one issue with engine wear. From extreme heat to Midwest winters this oil constantly performs.

The Very Best!

I am using this in my new John Deere tractor. It flows well in winter making cold starts easy. It’s is resistant to thermal breakdown as I have had this oil in my tractor long enough to see oil consumption is virtually non existent. You spend. Lot of money for a diesel so you want to make darn sure it hold up to hard use can throw at it; even with that, the oil has not changed color. Durability and longevity is what I want in my investment and Rotella will take me there!

Only diesel oil I use!

Always use Shell T6

Oil is oil

Oil is oil the older your car I say use higher viscosity

superman oil!!

how do i keep adding stars..its stops me at 5. I discovered t6 10w30 in desperate attempt to keep it running as a gasoline engine. not only did it keep it running it revived it reswelling gaskets and getting a superiors oil too the top of heads that completely stopped all lifter ticking, smoothed out rough running vibration, from regular oils, increased fuel economy and increased performance in a engine had i put conventional 10w30 was certainly doomed to die without T6. So when i bought my my t...

t6 15-40 shearing the oil short time

i have buying t6 full synth 15-40 for my two powerstroke 05 ford 6.0 diesel and 08 ford 6.4 diesel in my 6.0 engine i change every 2000 and at the most 3000 miles and because after 1000 the shearing is very noticable at 500 miles its completely black i now the 6liter are hard on oil but i have spent well in the thousands in oil changes just year rotella t6 nothing else

Works in my Kawasaki Versys

Did some research, and found out that the T6 15-W40 oil has all the necessary certifications to be used in a motorcycle, even with a wet clutch. This oil is a quarter as expensive as the Castrol or Motul oils I was running before, and at least around 2k miles in, it seems to run just as well.

Mileage on 2004 GMC ENVOY XUV

I have been running T6 Rotella in my Envoy, this vehicle has 343000 miles on it now and continues to run very well.

Use it in everything from Escalade, Mower, Q7

This stuff is excellent. I add this to all my vehicles, my Escalade, X5, Q7, Explorer, Silverado... on my German cars I add Ceratec. Per oil analysis, it does excellent.

Lives up to the claims✅

I’ve legit been using this oil in my trucks since 2013 and haven’t touched anything else since. This oil has saved me much money and kept my trucks from being placed out of service due to engine and turbo issues.

Love it

I run it in my drag truck, Holds up to the heat and RPS for the whole season.

Problom solver

I use T6 5W-40 for all non catalyst engines from small engines to tractors and older gas trucks. I live in ND where the temps range from -30F to 100F in a season and this oil has performed excellent in both gas and diesels. The only thing that sucks is the ZDDP will smoke o2 sensors in newer vehicles so I quit using it there. Nice to have one oil do the job of three.

Best for my DURAMAX

I have well over a 100,000 miles on my 2017 GMC L5P , it does not burn a drop and don’t have to change as often, no issues what do ever

Great oil at a great price.

Great oil at a great price. I’ve used this for years in my diesel as well as my gas engines.

Great Product

I have been using ROTELLA Full Synthetic for 10 years in my Honda ST1300. I Change it every fall when putting the bike away for the winter. I have 180000 km on the bike. It does not burn a drop of oil. This bike is not a stranger to the far side of the speedometer.

ONLY OIL I WILL USE

I USE THIS IN MY 2000 CATERPILLAR 6NZ, AVG ABOUT 5.9 MPG. I ALSO USE THIS IN MY FORD 6.0 POWER STROKE, MY HONDA VTX 1800 STREET BIKE AND KAWASAKI BRUTE FORCE 750 SINCE IT HAS THE JSOMA RATING.
