good deal, good quality

great price

Been using for years in Motorcycle, gas and diesel motors. First used for my motorcycle then started using in everything else to keep it simple. Seems a waste for diesel w/ 3 mos. oil changes low hour tractor. I believe it is a highly engineered lubricant available in some form, throughout the world. (almost)

Great Stuff

These work great on Subaru, I used them on turbo and non turbo, it stopped eating oil. Highly recommend.

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.

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

Been using Rotella synthetic for years used in cars trucks and motorcycles since new 87 kawasaki concours 1000 60,000 miles + 93 Pontiac Bonneville into 130,000 Yamaha V-Max 19,000 miles, 2009 Chevrolet Avalanche 202,000 miles, also used it in Kaw.Concours 1400 and Piaggio BV250 Scooter, ULTIMATE PROTECTION!!!

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 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.

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!!

I do my own oil changes and have been trying to find a better way to purchase the oil I needed for my truck, this is perfect, price is better than you can get anywhere, even for the 2.5 gallon container, and shipped to my door within a few days of ordering. I highly recommend shell Rotella, I have been using it for years in my old 7.3l power stroke and now getting this new t6 blend for my 6.7l powerstroke

Rotella T6 5w-40 was my go to oil for all my diesel trucks and farm equipment. Sadly it's no where to be found and I have winter maintenance to perform on equipment before spring tilling and planting. Emailed Shell for assistance and heard nothing in 60+ days. So forced to go with another brand which may now have to become my new standard. It's a shame.

I used this oil in my 2009 sprinter van . It provide excellent protection to this Mercedes engine which is equipped with DPF.

Great oil for almost any engine. I run it in my truck, tractor, motorcycle, lawnmower, and generator. One bottle to fill them all, makes my life easier.

I have been using Rotella T6 5W40 in all my motors car, truck,tractor, motorcycle, lawnmower, generator and all small engines. never had a problem my Yamaha 1600 Roadstar also runs much cooler

I switched to Rotella 2 years ago and the results are clearly visible. Used in motocross bikes clutches last longer and trans gears show much less wear. Really good product.

Just upgraded from using the T4 to the T6. want a lil better quality in my engine

This is a great product but can't seem to find it.

I bought this for first time best oil I have got yet

I have been using Rotella-T6 in the 5W/40 weight in my turbocharged SAABs equipped with the 2.3 liter engine for over 10 years. Used Oil Analysis performed at up to 300K miles show effectively zero engine wear.

Really easy to find at a great price. Awesome rebate. I can run longer oil change intervals. Flows better in my cold climate. Would not use anything else in my duramax. Very happy!
