I have used this in both my 1997 f250 7.3 and my 2005 f250 6.0 with no adverse issues at all. Best level of oil for the price before you start considering the Amsoils and Redlines that cost double. As long as your sticking to a routine schedule of changing the oil and filter, the Shell T6 will do more than its part in taking care of your engine and its internals. If your trying to go over 10k miles in between oil changes step up to the top of the line oils and pay the premium, but thats on you. Use genuine Ford filters with this and your golden. But i cant stress this enough, stick to routine maintenance intervals for your truck and they will last you hundreds of thousands of miles. Also always compare between walmart and amazon cause they go back and forth in who has the cheaper prices.

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 a bypass oil filter (installed at 10,000 mile oil change) which gives my T6 the absolute best filtration. Engine has run great and, at 93k still sounds as new. Don’t even think twice about using T6 in your diesel. Everybody has their pet brand. For me it’s shell T6.

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.

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!

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 change oil every 5-6000 km. If your looking for the best fluids to run in your diesel pick up this is it.

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!

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.

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.

Ive bought countless gallons of this oil for my 2 motorcycles. I run this oil in a 1994 Ninja ZX6E, 2012 KLX250S. Both run flawless. It provides amazing wet clutch shifting. My ZX6E when I bought it had Mobil 1 10W-40 in it before and my 2nd gear often slipped a lot. I was worried big time I bought a junker. Swapped out the oil with some Rotella and well 2 years later that slipping never occured again. Ive completely forgotten that ever happened now and its been a strong runner ever since. Solid oil that constantly impresses me in all my bikes. I recently had a valve adjustment done on that ZX6E and the mechanics were very impressed with the cleanliness of the motor. Keep in mind that motor is 20yrs old and has had 75,000 miles on it. Thats not a lot for a motor but few bikes ever see that number. With Rotella I easily have a 100,000+ mile motorcycle on my hands. Im sticking with Rotella as long as I ride motorcycles and ya of course the price keeps me coming back for more and more. If you ride a motorcycle..... and I mean any motorcycle currently on the market you owe it to your bike and wallet to buy this very hard proven oil.

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!
