Quaker State Advanced Durability 10W-30 Conventional Motor Oil, 5 Quart

I've been using your product( the conventional advanced durability) in my 2003 buick century (its my first car) and let me tell you, the car runs so much quieter and you can't feel one vibration of the car when you pet quaker state in it, been driving for 2 years now and this is the only product ill use in my daily commuters. Thanks quaker state for this fine product.

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.

Ok this is a little unfair....being a female, I don't do the work on my car...does it count if my mechanic does?...Lol I would love to win this toolbox for a friend of mine who would die for it! Fat chance, right? [This review was collected as part of a promotion.]
