Mobil 1 is all I’ve used in any gasoline engine that I’ve had for over 25 years. Never an engine problem related to lubrication. A good example is a riding mower I’ve had for over 25 years that still is running strong and never torn down.

Mobil One is a little expensive but I a sold on using knowing that I lost a lot of my oil at one time but this oil protected my engine. And Sam Club has it at a good price during the sale.

Seems to perform OK. It's really difficult to know any difference in oils. It has a good reputation is why I use it however I do not go 10,000 before I change it as it relates to on the packaging.

Best oil there is. I used it on my last new car and it last 376,000 miles and 18 years. Took the valve cover off and it was super clean on the inside. You can’t complain about that.

My engine runsure a lot smoother with the Mobil 1 motor oil doing it myself than when I had the dealership do the oil change. I've always trusted the Mobil 1 motor oil and had good experience with it.

I have used Mobil 1 Synthetic for many years in different weights including 0W20 and think it is the best. Mobil 1 synthetic Trans fluid instantly fixed my GM 8 speed that had been rough for 20000 miles. Amazing stuff

I change my own oil and use Mobil1, so I know it's done right. My cares are a huge investment, no reason not to stick with the best. I change the oil every 5,000 miles, and the old Mobil1 still has a nice amber color.

This is the synthetic SAE grade recommended by Toyota for my 2015 Prius. The sale price makes it a great value. I have used Mobil 1 on all my cars since they were new.

All of my Corvettes came with Mobil 1 I won't run any thing else in them. I use Mobil 1 in all my cars, My Ford Explorer has over 200K on Mobil 1 still runs like the day I bought it

I switched to the advanced fuel economy blend almost 5 years ago in both of my vehicles. I enjoy the fuel savings & the assurance that I don’t have to change my oil as often because of the quality of the synthetic oil.
