4Great synthetic motor oil.... a little shy of 5 gallons.
By Pete
I bought this 5 gallon pail thinking I would get two oil changes for my diesel truck which needs 10 quarts per change. I carefully measured the quarts for the first oil change, using only 10 quarts. That should have left 10 quarts for the second change. When I did the next change, I came up 3/4 of a quart short. I called the company and was told they fill the pails by weight, not by volume or liquid measurement. I informed them that I had purchased 5 gallons, regardless of how they fill the pails and that i was now short for a complete oil change. The customer service person apologized and immediately sent me a couple quarts, free of charge. I was advised that they would be looking into the filling process to ensure that 5 gallons was in fact 5 gallons.It is a great synthetic oil and I am very happy with it. It deserves 5 stars and I would have given them except for the short change....

4So far, so good. But how can a consumer truly rate motor oil?
By 3rdGen
My 6-cylinder car has over 167,000 miles on it and the motor still purrs like a... well, you know. I recently added Royal Purple 15W-40 for the first time. After driving perhaps 1,500 miles with the Royal Purple, everything seems fine. The motor still purrs. Besides, how the heck can a regular consumer like me rate a motor oil unless something goes horribly wrong? If all goes well, you simply say that it's good stuff. And how does a regular consumer justify paying the price of this stuff? Perhaps in a year or so, when the Royal Purple has 12-15K miles on it, I wll give it another review. For now, I'll just say that...having it in my engine gives me a little more piece of mind. Just a little.

4Royal Purple oil is majestic
By Russell E. Riel
Yes, the product arrived as promised on time. No shipping snags and despite my own hesitance about buying a five gallon "pail" of motor oil, it all occurred just fine. Amazing. If you want royal purple, this is the way to go. low cost and no shipping charges "added on": how can you beat it. Its pretty hard to get royal purple at $7.24 a quart.Give these guys a try, you'll be happy. VTY, Mr. R.
