Been buying Mobil ! since the 1970's...Never once have I had a engine failure..Never once has my engines used oil...Forget the rest, I buy the Best!!!

I have been a firm believer in Mobil one for years now, I’ve had several trucks with 350k miles plus before trading them off and never had a single issue. Pull the valve covers or oil pan and you’ll be shocked how clean everything is.

[This review was collected as part of a promotion.] For me this is the only oil. I’ve been using Mobil one since my twenties and it has never let me down. It’s the only oil that I trust.

Mobile 1 has been the only oil that I have used since it’s inception onto the market. The time between oil changes has been around 7,500 miles and the vehicles do not show any excessive usage between changes.

[This review was collected as part of a promotion.] This oil does what oil should do. I was hoping it would help with fuel mileage, like it leads me to believe, but I have not noticed a difference at all. Other than that, it works great.

I have used Mobile 1 for the past 30 years in all my engines, Auto, cycle, mowers, all my internal combustion 4 cyc engine. Superior results, excellent performance against internal ware & increased mpg as well. I can’t say enough about this product!

[This review was collected as part of a promotion.] I bought this oil not knowing it’s the oil all repair shops use when they change your oil! My dad changes his own oil and when I gave him the box of these he was very pleased then changed my oil.

[This review was collected as part of a promotion.] Mobile 1 OW-20 Advanced Fuel Economy Motor is a good qualtiy motor oil! I used this to do an oil change in my Toyota Highlander and my vehichle is continuing to run smoothly after the oil change.

My 2010 Toyota Prius went 270,000 miles using Mobil 1 0W-20 and nothing else. It would still be on the road today had the transmission not bit the dust. I can't say enough about the Mobil 1 products.
