I own 3 vehicles. A 1998 Chevy K1500 5.7 Vortec, a 2018 Ford Mustang 2.3 EcoBoost, and a 2016 GMC Sierra Denali 1500 6.2 Ecotec (0W-20). I’ve tested every major brand of motor oil there is on these vehicles and none of them came close to comparing to Mobil 1! I would highly recommend this product to anyone that feels like they could benefit from a strong and smooth engine!

I have a 2001 GMC Yukon XL with 169,000 miles on it. It has been in the family it's entire life and has used only Mobil 1 Full Synthetic. It has never had any engine problems and the engine runs just as good as new. Never will use anything else other than Mobil 1.

The oil pump went out in my 06 C6 corvette. I always use 5w30 Mobil 1 extended. Long story short, there weren't any shavings or glitter in my oil pan. I just got the car running again and it runs great. No bearing damage no crazy sounds. Thanks for oil that may have prevented a $7500 rebuild.

It killed my 2011 …………………………………………………………… Volkswagen tdi

Nascar uses it, so do I.

I have a 94 camaro with 267,000 miles. I have used Mobil 1 in it since the car was new. I replaced the valve cover gaskets last month and the rockers looked new. I will only use Mobil 1 in my other vehicles also.

I've used Mobile 1 oils exclusively in my performance cars and daily drivers for years. It always comes out as clean as it went in, and never have had an issue with sludge. Definitely the best oil if you want to take care of your engine.

Have used this product in my last 5 corvettes and can say that in my opinion it is a very good product and does exactly as advertised. I have never entertained the thought of another brand as this product has excelled in my opinion.

I own an express oil change I do a lot of oil change and this is the best for my customers they happy and the cars are running like new I keep it clean I love it

I have used Mobil1 extended performance oil in my 2 cadillacs from day one and it works perfectly! After 103 k miles, no issues. My cars never uses a drop of oil.
