Best Oil on the Market
Would RecommendI have used Quaker State Motor Oil since I started driving my first car that I still have 1969 Chevelle SS396. I started driving in 1979. I used Quaker State because it was Refined from Pennsylvana Grade Crude Oil. I have a 2014 Chevrolet Silverado 1500 5.3L V-8. And it gets Quaker State. I still have 4 cans Full of Penn Grade Quaker State Oil that I have saved over the 36 yrs that I have been driving. Thank You Quaker State for making such a fine product to protect my engines.

Would RecommendI have used Quaker State for decades in both old and brand new vehicles, 4 cylinder and 8 cylinder vehicles. I also use it in my lawn mower. By changing my own oil regularly I am confident that this product extends the life of my investments.

Would RecommendI change oil every 3,000 miles in 3 vehicles, this product has always worked great. One car is about to hit 400,000 miles and I have only used QS. No internal engine repairs ever!
