Ratings & Reviews for Shell Rotella Rotella T6 15W40 Synthetic Diesel Engine Oil 1 Gallon

great product at a decent price

I have been using this oil in my cars for 30 years.

Good For The Long Haul

I have been using Rotella T in my Goldwing motorcycle since it was new in 1995. 225,000 miles later, no clutch problems, and my bike uses 4 oz of oil every 10,000 - 12,000 miles, when it is due for a fresh batch. I change it once a year, whether it needs it or not! Good Stuff, wish they made it in correct weights for my car and pickup. I settle for Pennzoil Ultra Full Synthetic in them, but always wish for Rotella Synthetics! I also use Rotella T in lawn, snow, and garden equipment, where heavy ...

Not sure why Ford doesn't want this in the 6.7

On my second oil change with T6, not sure why Ford doesn't recommend it for their 6.7 diesel motors. The engine absolutely runs quieter than using MotorCraft or T5. Excellent product in my opinion.

Just a great motor oil

I bought a 2003 Silverado and put in QS AD 5W-30 in it. I change the oil every fall before winter, and each time the oil comes out clean and the truck runs as quiet as my 2012 Cadillac CTS. Just an outstanding product.

Use in all my vehicles

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)

Excellent all-around oil for heavy-duty use

We run it in gasoline-powered endurance race cars now. Same protection as Mobil1 0-40 we used to run, but way cheaper and more available. Once had a car come in with a badly warped head, no coolant, and boiling oil (coolant hose burst and the driver didn't notice) - over 10 minutes out on track without coolant! Still kept the rods in, no hard parts got damaged. Highly recommended! I use it in street diesels and my motorcycles, too - also works great there.

Best Oil I have used

I've been using this oil in my 2010 Genesis Coupe 2.0T for almost 2 years now. Love it! Wouldn't use anything else in it.

Motorcycle oil?

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

Great quality

I bought to do the oil tune up on my vehicle and it's proves to give my truck great engine performance.

Running T-6 for years

My duramax and I have been extremely happy with T-6. Starts great in winter, even when -30. Made mistake of using oil a friend gave to me, truck didn't like it when temps went below freezing, started hard. Won't deviate again.

5W-40 T6 is amazing

My Eco-Diesel Ram runs great with this product, it's slightly expensive but for a good reason. Including the fact that I get rewarded for using the product.

Durability is important to me

100,000,plus miles 1999 caddy,doesn't burn a drop!

Always has been a great product.

I always use Quaker State and will keep doing so. My truck has 194,000 on it and it's running great and I believe it's because I maintain my Truck on a regular basis.

Quality and Quacker start with the same letters

Have always used Quaker State for my older vehicles because that is all i drive

used this oil in many car I own without any problems

Classic Quality Motor Oil

I`ve used Quaker State Advanced Durability motor oil for years. It has always been my choice whenever I have changed my own oil, and also when I have gone to professional automotive services. Quaker State has never let me down with providing maximum engine protection against untimely wear. I have one vehicle that is approaching 300,000 miles for which I use the High Mileage blend. It`s all the quality you will ever need in a motor oil at a price you can afford.

It works!

I use this and I am so happy with the performance and the noticably difference of this oil! It's worth it to use this!

Topped off with it

Once I roped off with Quaker state and it worked just as well as the Castro thx I had in the truck. Was a long time ago and don't have the truck anymore.

Best Oil!

I got my first car back in 2004. I chose Quaker State because the commercial on TV stated that Quaker State was proven tough against failure and breakdown. I was sold. I have been using Q.S. ever since in all my cars. I still own them and are still on the road today! I will be loyal and use Quaker State for Life. Just like Quaker State has been loyal for my engine! Thank you for a great product!!
