Mobil 1 is the best oil for an internal combustion engine because it stays fluid at very low temperatures. When you start your engine on a cold Winter day, that is where most of the wear and tear occurs. Mobil 1 mitigates that. Worth the extra cost. I use it in everything, vehicles, lawnmowers, snowblowers, generator.

The best oil you can put in your cars! In a world of "Synthetic Oils" Mobil 1 is one of the few true synthetics.

I have had $90.00 plus oil change charges and regularly pay about seventy dollars. By changing my own oil using the oil and buying a quality oil filter I spend about $45.00.

Put in my Chevy 2001 Silverado HD, no issues. Great oil and works out that it's 6 qt box so that's the one exact amount my vehicle takes.

Most folks knows mobile one is the best but hard to find at the price I have purchased it. I am so happy finding this motor oil at that price. This is a good stuff that lasts longer than regular motor oil. I recommend this for anyone uses fully synthetic motor oil.

[This review was collected as part of a promotion.] It was the type of oil that I was looking for. Also, the brand that I was looking for.

I have been using Mobil 1 for years with great results. Thank you Mobil 1

Good product at value price

Great product. Recommended by Chevrolet for use in my 2000 Corvette

[This review was collected as part of a promotion.] The oil is good quality but I didn't et all of it that I needed. After ordering and paying for it, I found out Walmart didn't have all of it that I needed.
