Works as promised. Oil is clean, flowed nicely from bottle and cars runs smoothly. Will consider for my next oil change.

Have only used Mobil 1 oil. Have not used 0w-20 until my recent cars have required it. I have never Had any issues while using Mobil 1 oil.

Highly recommend this product for any Toyota or Honda car! It actually does what it says--it will increase your mileage by 3-4mph!

[This review was collected as part of a promotion.] What I needed but cannot rate quality since it is motor oil.

This is very good oil. I usually change it every 6,000 to 8,000 miles depending on driving conditions.

I have been buying Mobil 1 oil from Sam's for several years and have been very pleased with the performance I get from it.

The Best motor oil for your vehicles, I use Mobil one in all my cars and never had a problem even at 200000

[This review was collected as part of a promotion.] This oil found at my Walmart store is the oil recommended for my new car.

Our 2007 Sienna 160k miles , looks as clean under the valve cover as new. Not stained, resin or other buildup.

We have 5 vehicles, including a vette and a SSR. We always use Mobil1 religiously and have never had an issue with our engines.
