Shell Rotella T6 Full Synthetic 5W-40 Diesel Engine Oil, 1 Quart

Best oil made for diesel engines and at an affordable price.

I love this product for my diesel vehicle. It is of good quality.

This fits perfectly in my trunk for when I need to top off during the 5k miles between each oil change for my BMW e61. I use to carry around the gallon size jug of oil. This is much more convientient. Only have to top off twice every 5k miles. Couldnt find it anywhere but I found the quart size! Makes life so much easier.

I have been running T6 in my Kawasaki touring bike for over 45'000 miles and does it ever work great. My engine runs very hot and there have been no oil breakdown and no clutch slippage even pulling my touring trailer. The price sure beats the ten dollar a quart "motorcycle oils". It has the JASO MA rating that Kawasaki requires

I have been using this oil in my 1998 Honda F6 Valkyrie Tourer for 6 years now, and have had no issues with clutch operation. Even at full throttle with the big 6 cylinder engine, no clutch slippage. Also, the notorious Valkyrie top gear whine was a lot quieter immediately after the first oil change. It's also priced a lot cheaper than the competing oils, a nice added bonus. I don't hesitate to change the oil when I should, when the price is about half of other high end or OEM oils. It's available at many local retailers, so, it's easy to obtain. I wish it was available in other weights like 5W20. I would use it my 2010 F150 5.4L if I could, because it's really not that much more expensive than conventional oil.

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 have a 2016 F250 with the 6.7L Diesel motor and I use Rotella T6 every 6K miles. I use the truck to tow a two horse trailer and it never has any issue with getting hot or excessive fuel consumption. At the oil change interval I inspect the oil coming out of the oil pan and it still has a good viscosity to it as well as it doesn't smell burnt. I will continue to use this oil until I either get a new truck or the tires fall of this one!

Okay folks, I have a 1990 miata. Bad lifter tick like baaaaaaaaaaad lifter tick. It was ticking louder than the clock did in high school when it was the end of the day and you just wanted to go home so you were aimlessly starring at it waiting for it to hit 60. ANYWAYS, i did an oil change on it and used this, cause everyone in the Miata community swears by it. After it was all said and done I went on a little cruise and oh my god. It's gone. No more ticking nothing. And I swear my little Miata is running better than it ever has before. A1 stuff man

Anyone with a Ford 6.0 PowerStroke who lives in a climate where it gets below freezing knows the engine makes knocking noises and is loud & unresponsive when the engine is started in cold weather if the block heater has not been plugged in. With synthetic Rotella T6, though, the engine is much quieter, and does not require as much warm-up time as compared to using conventional oil. Even if one uses a block heater at home, most people don't have that luxury to keep their truck plugged in while at work. It sure makes the drive home quieter and faster, not having to let the engine warm up as much before hitting the road

I have a Kawasaki 1500, model year 2000. I switched to this oil because someone with a similar motorcycle tried it and liked it. Major reason for me switching to this is because it was a full synthetic and very reasonably priced compared to other full synthetic motorcycle oils. I've put on 2000 miles since my oil change and I have started to notice severe clutch slippage. At first it was barely noticeable but as of right now, I have a hard time getting on the interstate without it slipping. Now, whether it is due to the recent oil change or some other Factor, I'm not sure if I would recommend this oil for anyone to use in a wet clutch motorcycle or not.
