Quaker State Motor Oil, 10W-40, 1 Quart

I have been using Quaker state oils for 47 years.I never had a motor issue.I have 4 cases on hand for further use.This is the first time I ever wrote a review but wanted to let you know how pleased I am with this product. THANKS

I've been using Quaker State since I've been driving. {over 50 years} Always has given me great service with no mechanical failures.

I am 53 years old and have using Quaker State in my vehicles since my 1st car at age 16. My uncle started me using it then and i've never had reason to stop. Never have i had any problems what-so-ever and will continue to be a lifetime user. [This review was collected as part of a promotion.]

Have been using another quality brand, but changed over to Quaker Full Synthetic a couple of months ago. as my Cadillac uses 8 qts. The engine has had tiny lifter noises which come with the newest Gen Northstar Engine. I put on 5,000 miles a month and change oil. Now at 6,800 miles the noises are gone. I have 7 vehicles and will use QS in everything. DEXOS has been added which smooths the cylinder walls for more power and the rotating parts for less noise.

I drive 40,000 miles a year for my job and have used Quaker State conventional oil for the last 22 years. I usually put 250-300,000 miles on a car before I sell it. Quaker State has been a reliable oil and wouldn't use any thing else. Oil change intervals are 5,000 miles. I have never had any seal or gasket leaks when using Quaker State.

I 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.

I have used Quaker for most of my life. I have an older Volvo now and previously. My GLT VOLVO had lasted with over 435,000 miles w/o any major repairs. I attribute this to the Quaker State oil that I used in it. I will continue to use Quaker State oil for my S90. Thanks Quaker State!

Ive been using quaker state in every single toyota that ive owned and have never had an issue what so ever! I swear by the stuff and would highly recommend this product to everyone owning a engine.. Sincerely a very satisfied customer! Joe legendre [This review was collected as part of a promotion.]

I tried QS in the past on my 98 Corolla, and I didnt like the results. I found I was burning oil faster with QS than other brands. But in Sept 2014, I put dino QS in my 2004 4Runner and it has never run smoother. Whatever QS did to the SN version of the oil has sold me. Ive used high priced synthetics that didnt impress me as much as these last 2 QS conventional oil changes

Been using Quaker State for years in many different vehicles that I have owned and have always been satisfied. I own a 1969 All Original Ford Mustang and from the very first oil change, I have used Quaker State Oil. Engine is still like brand new and has never had any major repairs. I believe I may still have a quart of 10W-30 Quaker State oil in the old metal can from the first case of oil I bought years ago.
