Quaker State Ultimate Durability SAE 10W-30 Full Synthetic motor oil contains the most powerful formulation in the Quaker State portfolio. This product offers superior resistance to thermal and viscosity breakdown compared to Quaker State Advanced Durability Motor Oil. As the engine temperature increases, the heat-activated shear stable viscosity modifiers work to maintain oil film thickness that is necessary to prevent engine parts from metal-on-metal contact which helps extend engine life*. This motor oil maintains its viscosity from start to finish, which means it stays in the grade specified by the car manufacturer throughout the recommended oil drain interval. The product also contains special detergents and dispersant additives that are designed to neutralize the harmful acids generated by the combustion process. This helps prevent the formation of sludge and deposits from forming on crucial engine parts. These properties of Quaker State Ultimate Durability full synthetic motor oil make it reliable and suitable for use in high performance vehicles such as sport cars, SUVs, trucks and minivans. It is compatible with biofuels, ranging from E10 to E85 and suitable for hybrid vehicles. *Compared to Industry standard Seq IVA engine test

I use the Ultimate Durability full synthetic in my Ram 1500 and my wife's Kia. Both engines are at their quietest when I use Quaker State. I have tried many different oils in the past, but I find QSUD to be the best. I used QS dino oil for years, but with the great price on synthetic it's a no brainer to switch. Keep up the good work !

I purchased my 2015 Ram 1500 3.6L new and got 8 oil changes with it and I noticed upon close to oil change the valves was making noise and when I did it myself with Quaker state full synthetic upon close to oil change NO VALVE noises and I noticed upon changing the oil I put in is a lot cleaner when changing.Now I don’t know if they were using proper oil I paid for at the dealership but my oil changes makes it run a lot better and gas mileage increased by 1.2 miles per gallon .
We have been using Quaker state full synthetic oil for over 10 years and it's the best bang for your buck synthetic oil out there. we use it in all 4 of our vehicles and small engines as well. Thanks Quaker State for making a great oil.
..bought a new mx5 Miata last year. After 3 thousand miles, I changed the oil with Mobil 1. Every morning upon starting the car, there would be a 1-2 second harsh metal on metal sound which just would immediately go away but didn't seem very promising for a new car. I dumped the oil and put in the Ultimate Durability and darn it instantly it stopped! Now, even after a week or two of not driving the car, it starts with the smoothest most refined sound coming from the motor. I'm sold on this oil.
I have used Quaker State oils in my Cadillac and my Chevrolet exclusively, and could not be happier. Even though my Cadillac is in storage, she fires right up, every time. Purrs like a kitten too! My Chevrolet sees weather from 105 degree summer heat to frigid 33 below cold snaps, and that doesn't phase him. Thanks to Quaker State, I know my Silverado will start the first time, every time. He runs like a race car too! I send oil samples to Blackstone for wear analysis, and every one comes back passing with flying colors! Quaker State fan FOR LIFE!
