Because it's not quitting time yet

Rated 5 out of 5 by Rick from Old Fords going the distance I have two Fords. The Mustang I have had for 25 years(150k miles) while, I've had the Cougar over 30 years (300K miles). Both engines see nothing but Quaker State. Any chance you can mail me a couple QS stickers for the racing boat?

Rated 5 out of 5 by traditions from It just works! I drive a 2006 Toyota Tacoma, 4 cylinder, 5 speed and use it like trucks are meant to be used, hauling wood, pulling boats, camping and it is also my daily commute vehicle. I've been using Quaker State from the very beginning, it know has 300,000 plus miles and still strong, current 307,000! I change the oil every 3000 miles. Great Product!

Rated 5 out of 5 by Robyflexx1674 from Awesome oil! Love this oil, immediately upon completing my oil change I can feel and hear the difference. My car starts up quicker and smoother even on a cold start, also runs extremely quiet and idles much better. Top quality oil you can depend on at a great price too?: Yes thank you!! Keep it up Quaker State..

Rated 4 out of 5 by SuprG from smooth I used to use the other name brand oils becuz I believed what i saw on their commercials. but i recently bought QS and put them in my 11 and 16 yo vehicles and I really like the way the engine purrs. Ive owned both vehicles since they were new and with QS Defy, they are running great. My oldest car isnt burning as much oil either. I used to add 1 quart after 1500 miles and the last 1500 I only needed a pint.

Rated 5 out of 5 by Chugging along from **Motor oil test(net)proves better than the rest!* Read some very interesting oil tests on the net. Quaker State beat out alot of the very popular name brand oils and it remained durable with increased heat. I guess Q.S. ads are true and I thought it was all just hype. I was wrong and very impressed, and will be using Q.S. synthetic! Keep it up and I will buy forever and recommend it to others. I also have one of those cool full transparent(all clear)bottles where you can see the oil. I reuse it so it is easier to pour oil for top ups. I think if Q.S. is on sale more at Canadian Tire more people will buy! Changing the bottle shape will be cool.

Rated 5 out of 5 by GEODRUSS from I have been using only QS oil in my vehicles since started driving, 1967. Have always been happy with the performance. I now have two vehicles with over 200000 miles on each. Have used QS DEFY since they hit 75000 miles. My problem is. That with over 220000 miles on my vehicles I sometimes have to add a half quart to a quart between oil changes. Which I expect. Problem is if I only need a half or even a quart. I don't want to have to buy a 5 quart jug, just to get a quart. But for the last couple months the only way I can QS defy motor oil, is in the 5 quart jug. Do you not put in quart bottles any more? Starting to think I may have to change brands. So I can get oil when I just need a quart. I have always recommended QS products to everyone. But now, Why should you recommend a product, when you know you may not be able to find it when you need it. Or the quantity, you need when you need it.
