Mobil 1 is the best oil for today's modern high performance engines. I always stock up when it goes on sale at Sam's.

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.

truck motor seems quieter after oil change and mileage increased 2 MPG for the first 500 miles so far.

[This review was collected as part of a promotion.] There cheaper price I save money. not like the Auto retail store there expensive.

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

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

Its a solid oil. Full synthetic is what is required in multiple vehicles i own and ive been running it for close to a decade with no issues.

I exclusively use Mobil 1 oil on all my vehicles. Knowing this top quality oil is lubricating my engines gives me piece of mind.

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

It’s easy to get the incorrect oil for your vehicle there are many “Synthetic Blends” in the market my vehicle calls for “Full Synthetic”.
