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

T6 15w40 full Synthetic

I live in a cold climate at or above 15 degrees, I just did a oil change on my 05 F350 6.0L powerstroke 90KM, works good but takes 30 mins for oil to heat up with engine heater

Used in 1997 7.3L Powerstroke or 23 years

I have been using Rotella in my 1997 Ford F-250 since I bought the truck new in 1997. I switched from T-4 to T-6 a few years ago and only use about 4 oz of oil between changes every 5000 miles. The truck starts much easier in cold weather. I have 178,000 miles on the truck and I have no oil leaks.

Oil for tractor

Been using this Rotella oil for over 10 years. Had good luck with it in my diesel tractor. Very disappointed at Lowe's in Olive Branch on their price. It was set at one price on the shelf, when I got home and looked at the ticket, I was charges with better grade Rotella oil. About $3.00+ more. Did not go back to get it corrected, I live about 30-45 minutes from store. Makes you wonder how many other items are priced on the shelf different that what check out is charging you. Keep you eye on th...

Best oil for my custom 1991 Volvo 740 turbo

I've been using shell rotella t6 5w40 for about a year now and this oil is awesome! Run it in my 1994 jeep grand Cherokee 4.0l and my 1991 Volvo 740 turbo and the engines love it they run alot smoother and quieter and shell rotella t6 5w40 is my first choice for my vehicles for the protection of the internal parts of my engines and to keep them running strong and running long!

Clean

I have 146000 on my f350 recently replaced all the injectors, when we pulled the valve covers off I was impressed they looked like new no sludge or anything. I remember 40 years ago my father in law told me to use shell Rotella if you want a clean engine. He was right.

Harley Davidson 2018 Road Glide

I used to run this oil in my Victory Cross Country, but I did feel the clutch slipping from time to time. Like most Harley guy's, I was very finicky with how I maintain my bike. I purchased an S&S 124CI kit for my Road Glide and was waiting for the parts to arrive. I still needed to ride until then, but my bike needed an oil change so I took the chance because I knew how well my Victory ran with it, plus I was just trying to be cheap since I had to dump the oil anyway for the new motor build and...

Off-Label use in Gasoline engine

In 2002, I purchased a new Volkswagen GTI with a 200 hp 2.8 liter V6 engine. The manual advised the use of 5W-30, but preferred 5W-40. I did not live near a metro area and the only 5W-40 I could find was Rotella T. I have used this oil ever since and never had an oil related problem. The engine does not use oil, so I never have to top up between 5000 mile oil changes. I had to change the valve cover gasket recently and was pleased to find no shellacking inside the head or valve cover. What resid...

2009 Yamaha R1 crossplane engine oil

Started using this in my 09 R1 after only running Yamalube since day one. The bike runs great. No issues with the clutch. Great price vs Yamalube. Plan to keep using Rotella T6.

Awesome oil

Use in my 2008 f150 had a cam phazer bad i mean bad so bad engine would stall. put 0w40 in disappered. Gone. Run up to 16000k between changes.

2004 Suburban Running Great

My oil pressure is sitting back up where I like it and reduced engine noise especially on cold starts. Engine sounds much better over all.

Best 5W-30 oil currently available!

I use this oil in my car's GDI engine and I know several people who love using it in their high performance Subaru engines like that of the STi, WRX, and Forester XT. It just doesn't shear like other 5W-30 oils often do. I am very happy that Shell offers this product but it is very difficult to find in stores and usually online retailers offer it at a more premium price. I hope it is made more commonly available in the future!

Best of the best

Iv ran a few different oils in my race bikes and ever since the switch from A recommendation from my father that has a gold wing with 90,000 miles no issues my race engines show very very minimal wear and tear in between seasons

Best bang for your Motorcycle Buck.

Used T6 in my 2007 FZ1 since I bought it used about four years ago. I rev this bike to the Max, never had a single engine problem, doesn't run hot, uses zero oil in between changes. I understand that it shears easily in a wet clutch situation (as do many oils) so I change it as I reach about 1k or 1.2k miles that way the engine always gets fresh oil. It's cheap and not that hard to change oil and filter. I only ride for fun so I change it maybe a couple of times a year.

Good Oil

I have been using the Rotella T4 15w40 in my Honda Goldwing GL1100 for a number of years. Smooth transmission and no clutch slip. 82000 miles done and no problems. The T4 along with T6 is JASO MA2 compliant.

Trusted for all of my engines.

I use Rotella T6 in everything. Currently running in my John Deere 180 with a Kawasaki motor, Kubota BX2370 tractor, Ford Explorer 4x4 mud truck, Chevrolet 5.3, and even a 2017 Subaru Legacy! Can't beat the performance.

Excellent Motor Oil for ALL My Vehicles

This is a truly excellent oil that has the ratings and approvals for all my vehicles, gasoline, diesel, air and liquid cooled. Rotella T6 is the only oil I buy for my cars, trucks, tractors, ATV's, UTV's, ZTR's, gasoline and diesel powered generators, a power washer, log splitter and other small gasoline, air cooled engines, basically everything except 2-stroke gasoline engines. I love only having to buy one engine oil.

Great Oil for my 2002 Ford Super Duty with the 7.3

I think that this one of the best oils on the market for trucks like mine as well as all of the new ones being built today. Why should we not use all of the newer oils to make our older Diesels last longer, if they help the new trucks, they should really help our older trucks that have some age on them and are still being used every day, for work, pleasure driving an just to have around. Mine has 268000 miles on it and I hope to put a Million Miles on it, if I live that long.

I use this for everything but my truck

This is my go to oil for everything besides my daily driver. I use it on my motorcycle, ATV, and lawn tractor. Great product and generally the price is reasonable.

Perfect oil

I use in everything from my ecodiesel to motorcycles
