Best price

Best price around for name brand full-synthetic. Especially for my vehicles that need 6 quarts for an oil change.

Worth the money!

The best you can use if you intend to keep your car for several years. Engine is very clean looking into oil filler hole after 195000 miles.

A good buy....when it's marked down.

I usually buy a couple of these when they are marked down.

Top notch full synthetic oil at a great price.

I ran across this as a Sam's Club E-mail sale notification, for $10.00 off per 6 qt. case.
