More economical than purchasing at the parts store. Always in stock, good brand, various weights and viscosities available.

Bought this oil before and it is good oil at a very great price especially if you catch it in their savings book!

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

Its much cheaper to buy motor iol through Sam's. I don't even have to go to the store it comes to the door.

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.

I’ve been using this oil for years in multiple vehicles with great results. Always buy it on sale and stock up!

Good Stuff. I've used this for about ten years, maybe longer. Three different vehicles. Never a problem.

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 now have a new Explorer with a TGDI engine and worry about fuel dilution, so I elected to use the high quality Mobil 1 in the engine.
