Quaker State 10W-40 Peak Performance Conventional Motor Oil, 5 qt.

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!

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!!

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.

Don't use anything but the best for my Mopars and recommend it to all of my friends. If you want quality, Quaker State is the only way to go, I've spent too little on some oils, and too much as well, but QS has never sold me a bad batch unlike the rest! Thanks Quaker State!

I have been using your oil for the past few years. When I had switched over from none name brand oil. I noticed right away the difference. In performance, response, running temp and I also believe it has helped alil with mpg. But over all I give this oil a 5 star rating. Great oil and a great company. I also run your oils in my tractors my dunebuggy and 4 wheelers and my wife's car. Keep up the the great work producing great oil. And you have a life long customer here.
