Excellent Clean Formula oil as full synthetic with xtra vitamins for hard working engines! Great in a wide variety of applications from year round small engines to turbo diesel tractors and trucks. Helps aid in easy starting with solid protection at higher temps and loads. Consult your manufacturer before using in place of any recommended oils.

One of the gallons of oil had been damaged and leaked oil soaking the shipping box. The box was then left on my front porch. There are now oil stains on the porch. The box had obviously been treated with very little care. The delivery person should have certainly known not to put a leaking box containing oil on a customers porch. At the very least the damaged gallon container of oil needs to be replaced.

[This review was collected as part of a promotion.] Excellent product and your on-line price is very good. You should carry the single quarts too. This product has a strong following among the automotive crowd and it's often in short supply in your stores. Stock more and you'll sell more.

I like this oil because I don't have any oil consumption issues. It is the recommended oil for my diesel pickup (10.5 quarts). I change it and filter myself at approximately every 8,500 to 8,800 miles (10K recommended by Ram). About .5 quart is missing when it is changed with the filter. This has been consistent since it was new. No leaks are apparent. Currently have 80K miles on the engine.

Motorcycle is a Honda ST1300 with 13000 miles on it. Have used the Rotella Synthetic, ostensibly advertised for diesel engines, but without the "high efficiency" additives, it works very well with my motorcycle. Clutch is just as good as new, and the engine uses no oil. To boot, the container has four quarts in it, and that just fills the ST. The Amsoil salesman stated that there is now no zirconium in Rotella T synthetic, but in my opinion there is a limit to the addition of trace elements to motor oil, and since the synthetic is a superior lubricant that will not carmelize, it is plenty adequate for everything except maybe flat out racing.

After reading several reviews regarding using this oil in my motorcycle, I'm glad I purchased this product. Rotella T6 is rated for motorcycles, and is an unknown gem for everyone who wants to run a full synthetic in their motorcycle and don't want to pay some of the sky high prices for full synthetics. Great buy, will be using this product in the future.

Shell Rotella T6 is the best heavy duty oil on the market. Price point for superior protection attracted my attention back in 2015. I have been through three 6.6L Duramax vehicles since and not one issue with engine wear. From extreme heat to Midwest winters this oil constantly performs.

This is the least expensive synthetic oil available that meets the specs for my metric bike (2012 Kawasaki Concours). I just started using Rotella T6 about 2300 miles ago due to not being able to find any specifically marketed synthetic bike oil for less than $10/qt. Apparently lots of folks have been using this oil as a substitute cycle oil for years with mixed results across the board from 'It's awesome' to 'It destroyed my engine/clutch'. My experience so far has been great with no noticeable difference between using this oil and using Valvoline 4T Stroke full synthetic. The shifting just after the change is smooth then becomes a little notchy after about 400 miles just like the Valvoline had in the past (the bike has exhibited this since new, now approaching 40k miles with 11 oil changes and the original clutch still chugging away). Sam's was selling this 3 gallon case for $forty-six seventy when taking off $fifteen for a special they had. At only $three eighty nine a quart I was in for enough to outlast this bikes foreseeable service with me.

And if you take advantage of the oils ability to take care of your engine for extended oil change periods, it is the most economical. Buy oil filters designed specifically for synthetic oil and extended oil change periods and you can safely change oil every 10,000 miles. If you install a bypass oil filter in addition to your regular spin on filter you can extend your oil change periods even further. On my truck and car I change the element in my bypass filter every 5000 miles. I change my spin on filter every 10,000 miles. I also send a small sample of my oil to an oil testing lab at regular intervals to determine if I need to change oil and to determine the health of my engine. I have purposely not endorsed any products other than this oil so you can do your own research.

i know this is oil for diesel engines, but a lot of owners with turbo gasoline cars such as Subaru WRX and STi's use it for their cars. I picked it up because I drive a Nissan 300ZX and fellow 300ZX drivers on forums were recommending this oil over Royal Purple, AMSoil, Mobil1, and all other full synthetic oil. I tried it out because Royal Purple was burning to quickly and after driving a while, my oil dipstick still shows clean oil on it!
