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

Have using it in m y 2016 Altima since I bought it. Mobil one has been my go to oill for years. Also purchase there oil filters.

Very slippery, nice color of brown. Mileage actually went up a bit over the synthetic blend that had been in there

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.

I used this for my Prius and easily hit 100k miles no problems. Now I use this on my Honda Insight. Engine idles nicely.

Thought the price was a misprint!! This oil is about $11 a quart elsewhere! Got all 6 for less than $40 at my Sam’s club!

Not sure if I notice any fuel efficiency gains or not but I do notice how clean my engine stays after running this oil a few times in it!

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

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.

A top synthetic oil at a good price. I use it on my Jeep Grand Cherokee. And, is the recommended oil for my Mercedes Benz GLK350
