I always use Mobil 1 in all of my European cars and have for years. My cars all run great for over 150,000 miles!

Mobil 1 is a quality product at a great price. Buying by the 6 pack makes it easier to keep the garage stocked.

Great product - have been using on all our cars for years and have not had any problems. Will continue to use it.

Mobil 1 5W-20 Motor Oil, the only brand I’ll buy. Packaged well, and arrived on time. Thanks Sams Club.

Great oil for many years, motors go for at least 350,000 miles without even pulling the valve cover or replacing any parts.

Ive been using Mobil One Since 1984. The cleanliness that this oil provides is excellent. Wal-Mart's Pricing Can't be Beat.

Tried other products but stick by the Mobil 1. A big fan, they have just what I need and can find just about anywhere.

I’ve been using Mobil 1 in all of my vehicles and tractor for the past 30 years. Never any engine issues.

[This review was collected as part of a promotion.] Quality and value of the products are outstanding.

Been using and trusting Mobil 1 5W-30 for over 30 years in all my cars and trucks and not once had any engine problems or failures. Great product.
