Ive been using Mobil One Full Synthetic for over twenty years in my vehicles and have never been disappointed. Better protection, better fuel economy, and better life of service.

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!

I’ve used Mobil Advanced Full Synthetic 10W-30 in my 2003 Dodge Viper since purchased and have been very pleased with the oils performance. I will not use any other oil. I trust Mobil 1.

I just did the oil change and switched it to the 0w20 advanced fuel economy and the difference is noted right away, miles per gallon increased from 29.6 to 30.2

[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.

[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.

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!!!

[This review was collected as part of a promotion.] Mobile has always been the preferred brand for my vehicles. Quality performance with every oil change. Definitely recommend.

[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.
