Great oil - best price I have found

I use this Rotella T6 in all my cars with synthetic requirement for oil. Its low weight and high viscosity - good stuff. Holds up well in my 350HP turbo application and also lasts the 7,500mi interval for my non-turbo car. I have even started trying in my motorcycle and so far seems good.

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.

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 better detergent packs than gas oil does. I want my van to run as long as possible. I am one of those people that drives a vehicle until the wheels fall off, so they say. Ive used other brands before and they have worked well, however, since changing to Rotella T6, my van has more power and response than I ever remember it having. Rotella and other Shell products will be my only brand now. Stocked up on quite a bit of Rotella in all its major types, T4, T5, T6.

Top of the line oil

Love this oil in my ATV. Turns smooth as silk. Some may question, why it's a diesel oil. Why you putting that in a quad. Trust me its JASO certified. Which is why I use it. Check it out and read up on all the reviews. YouTube has alot on this oil for motorcycle oil. I highly recommend

Great oil. Timing chain rattle on cold start gone.

I live in South Florida. I had a timing chain rattle on my Mercedes diesel OM642 on cold startup with the recommended 0W-40 Mobile 1. Mobile 1 did not have 5W-40 for Mercedes diesel so I decided to go with this oil. My rattle is completely gone. The only downfall is I have to change it at 5k vs 10k. I am okay with that since the motor seems to be running smoother.

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!

Great for Motorcycles!

Just bought a 2002 Kawasaki Concours motorcycle and the previous owner swears by this oil. Did some extensive research and online Concours forums questioning, this is THE stuff for improved cold starts, better shifting, and overall performance. Try buying full synthetic from motorcycle shop for anywhere near what Walmart is charging for this oil!

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 wear.

Best Diesel oil ever

Rotella t is one of the best diesel oils ever. And Walmart has the best prices on it AND they will deliver it to the house? Critical for someone like me who has disabilities. Walmart's delivery service is more than a convenience, it is a lifeline for those with disabilities.

T-6

Synthetic oil is always best for you vehicle. The Rotella T-6 has finally been added to Fords approved list of oils. In 2017 many vehicle manufacturers changed acceptable rating for approved oils and after much debate over the matter T-6 was added to Fords list.
