As the record would confirm, I purchased 2 - 5 quarts of oil As the price was right. Therefore I purchased an extra for the next oil change and received free shipping which is always an added incentive. The product itself has inherent quality.

Very Good for Work

This oil was recommended by my friend who has been a mechanic for many years and I've been using it on two of my cars ever since. I like to give good quality to my vehicles.

Synthetic Oil

To really judge how oil performs, I think it has to be tested over time. Most folks don't keep their cars long enough to know just how much difference there is between dino oil and synthetic. With that said, I have used synthetic oil long enough to know the benefits. I have maintained a friends vehicle since she got it new in 2001. 300,000 plus miles later, the engine still runs great. I have similar experience with a Poulan Pro riding lawn mower . . . 15 years of service and the engine is still as strong as the day I got it. Time between oil changes is extended vs. regular oil as well. I do use the Mobil 1 filters along with Mobil 1 synthetic oil. What makes it all that much better is that the price between synthetic and regular oil isn't all that much different as it has become more popular.
