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

Have been using Mobil 1 5w30 oil exclusively in a 2015 GMC. Current mileage is 145k. No engine issues at all over the years.

Use to buy a different oil but thought around the first of the year to try this Oil was even a little cheaper so I still use it

I have you used mobile 1 5w-30 for quite some time. I tow a pretty big trailer with my truck and mobile 1 has never let me down. Very satisfied!

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

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

I appreciate changing my oil and then forgetting about it til the next change, Mobil has proven reliabl\ility and I count on that.

I always come to Sams for my oil since they carry the fully synthetic oil at a great discounted price. It's great for me.

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”.

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