Product is as advertised

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.

Rotella T for motorcycles with wet clutches

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.

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.

The best choice for me and my Ford 150 powerstroke

I own a 2018 Ford 150 Diesel 3.0. Meets all the requirements (CK-4, and more) by the manufacturer to keep it under warranty. I use the 5w-40 because it is recommended in the owners manual if using bio-diesel or under harsh conditions. Use the ford filter from ROCKAUTO, Good price if you buy 6 . Shipping adds $1 to each. Well worth it. Walmart does not carry the filter for this engine. Always great results with Shell Rotella. Chevron DELO did not have the correct amount of additives needed based on my research from the ford spec sheet when I started to change the oil myself. Maybe it does now... I never looked back at it. Staying with the same thing going forward.

One of the best diesel oils for the old

This oil can't be beat for both value and how it handles the old school and new school diesels. Has all the right ingredients to handle my old 12v cummins with ease. Being a 5-40, much better in the winter months compared to the older school 15-40. I get zero burn off and this stuff just works. Highly recommend and have a friend that works in the R

[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.

Great for cycles!

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.

Great for hot weather and for hard working engines

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.

It’s disappointing that an expensive delivery such as this is essentially left by the road side. This particular Fedex driver recommended I get a drop box, so I did. She still dumps the packages right next to it. Fedex isn’t putting Walmart in a favorable light.
