Great motor oil!!
Size: 5 Quart (160 Ounces) Style: 5 Quart Configuration: 5W-30
I have been using this brand of motor oil for the past 2 years, and believe me: it is really, really great oil! My car is very satisfied with the performance that the oil provides. I will never use another brand as this oil provides all that you need in a motor oil. I even use the their lubricating grease for my ball joints and essential grease fittings on my car. Great stuff and worth every penny. Also, does not break down easily in viscosity, and I also notice that the oil stays clean until my next oil change!!!! ... show more

Fantastic Synthetic Oil
Size: 5 Quart (160 Ounces) Style: 5 Quart Configuration: 0W-20
One of the few oil products I’ve used where the is no noticeable difference in engine performance right after an oil change=means the viscosity and conditioners continue to work straight through to the end of its change cycle. Also one of the only higher quality oils that is readily available, easy to find, and is negligibly more expensive than the garbage many of the “Quick Shops” use. ... show more

Finest oil you can buy
Size: 5 Quart (160 Ounces) Style: 5 Quart Configuration: 5W-30
I witnessed the factory demonstration of this oil compared to all the major brands of full synthetic oil many years ago in Moab, Utah, at the Easter Jeep Safari. This was when this oil was first developed & only available at 4 Wheel Parts. Now it is everywhere. Simply has no peers. You want the absolute finest oil on the market? Look no further...... ... show more

Runs a lot better in my 2003 Chevy S10
Size: 5 Quart (160 Ounces) Style: 5 Quart Configuration: 5W-30
The shop that we usually took my truck to get the oil changed always put in a thicker oil than necessary into my truck. So now it is smack in the middle with the oil pressure it needs. Runs a lot smoother, and she notably doesn't have to work as hard in order to move.
