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

Zero problems with this oil!

I've used the Rotella T6 5w-40 for years and years in motorcycles with wet clutches, trucks, and tractors and had no problems. Most notably I've used it in: 2004 Honda Shadow Sabre 1100 (wet clutch) and put 30k+ miles on it and I used it in my 2011 F-150 for it's entire life (bought new). The F-150 is impressive because it had the 3.5L Ecoboost, the first year of that engine, and I put over 218k miles on it with nothing done to the engine except oil changes and spark plug changes. I also use ...

Marine diesel switch to T6

I have a 17 year old Volvo TAMD41P-A diesel in my 31' recreational trawler. Prior engine oils for the prior owner (11 years) and me have been 15-40 dino oils, until I switched to full synthetic engine oil, also 15-40. Operating temperature dropped 5 degrees at standard cruising RPM of 1800 to 2200 (only one of two thermostats in place most of that time), the engine runs quieter and more smoothly. Based on research I have found, I know that my engine is running cleaner, with other attributes o...

Can't use what you can't find

Been trying for months to get moreT6. Luckily I had enough for my last oil change but I like keeping it on hand. I can not find why and when the shortage will end. Next change I will be looking for other brands

almost 100 mi round trip

I had to travel 50miles 1 way for the VERY LAST GALLON of T6 in my area of Western Pa.

Ram 3500

Bought my 2011 Ram 3500 Cummins 6.7 in 2012 with 300 test miles on it. Put Shell Rotella T6 in it right away and have run nothing else. Great oil, but hard to find right now.

Tired of the supply chain issue and not getting th

Have been running T-6 5W40 since 2011. Never had an issue getting the oil. Now I have had my first oil change in my 6.7 PSD and had to use Mobil Diesel oil. 5,000 miles in and can hear a difference in the sound of the engine. So, shell when I get my oil sample back will you still honor your engine warrant since I was not able to get your oil ? Yes seriously I miss your oil and hurry the heck up and get t-6 to us!!

Can’t find it.

Would be great if a person could find it in a store.

Daily.

I use it for the drift car but as of lately there’s been a shortage and I don’t wanna change oils. Can we fix this. It’s the only oil I use.

Excellent Oil

After hearing and reading rave reviews on this oil, and reading posts about it on oil-focused sites and forums, I thought I would give it a try. Im running it in my 04 Grand Caravan with the 3.3L V6. Running a half-and-half mix of 5w-40 and 15w-40. Let me say this, my van has never ran so well just by changing the brand and type of oil I am using. It currently has 209k on it and runs like a top. I switched to diesel oil because it has a higher film strength, better wear packs, and bette...

No oil!!!

There is no oil! It cannot be bought! Why? When will the oil be available? When????

Stock 2005 Subaru STi

Ive been using this oil on my Subaru for over 10years now. Currently mileage @230k miles There has been a shortage recently of T6, And I may need to use an alternative 1/2022

I run this in everything I own

Great product for cheap. I run it in a 2001 twin turbo Audi V6 - 170K miles change at 10K miles, 2002 Nissan Pathfinder - 180K miles - changed at 5K miles, BMW R1200GSA motorcycle - 133K miles - changed at 4K miles. This oils exceeds all manufacturer's specifications, never had any issues. Last time I opened the valve covers on the bike it looked brand new in there at over 100K miles

I run this in EVERYTHING.

In my motorcycle - 2015 BMWR1200GSA - for over 80,000miles In my 2001 Nissan Pahfinder with VQ35 engine. In my Honda scooter (not that the scooter cares what oil it gets) 6.0 Powestroke diesels love this stuff. (I used to be a diesel mechanic)

Trust this oil.

I trust it. I use it both in my BMW motorcycle where it protects in temps up to 117F a few weeks ago, as well in sub-freezing temperature in my Subaru with a turbocharged engine. Those first few seconds at engine startup are critical.

The amount of wear on my Corolla engine was so low

I ran this oil in my Toyota Corolla for 10,000 miles, and had it tested by Blackstone Labs, and the amount of wear in those 10,000 miles was so low that it almost could not be measured, and Blackstone said that the oil was still pristine, and that I could easily run it for another 5,000 miles.

Give me synthetic or, give me nothing!

I have a 05’ Chevy D max since new. Dino oil that came with it for the 10,000 break in and changed it with T6 ever since. C’mon, you cannot see what is happening inside you engine unless you break it down. The premise of using a good quality synthetic motor oil is based on the comfort that you WON’T have to break it down because you know that oil is making sure your engine is getting lubed. Diesel engines are quite expensive so putting the best oil in equates to as little wear as possible. I use...
