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.

I have been using Mobil 1 5w-30 in my Chevrolet S10 for 15 years now. I switched to high mileage when it reached 300,000 miles. The truck now has 548,000 on the original engine and still runs very well.

Been using this in my 2013 Accord. It now has 140k miles. I change approximately every 10k miles. I’ve never had to change oil between changes.

I use nothing but Mobil 1 in my 2016 5.0 L Supercharged Mustang. There is no substitute for this oil in my experience as a Tribology Engineer.

[This review was collected as part of a promotion.] I absolutely love this brand. It is the only oil I put in my vehicles for oil changes.

Great product I 've changed the oil with Mobile One every 8,000 miles since the car was new! Runs terrific just like or better since it was new

I have a 2020 car with about 15,000 miles on it and I guess I am from the old school but I change my oil every 5,000 miles

I change the oil in every car when just before the max oil % drops below 5%! Never had a problem using Mobil 1.

I’ve been using Mobile One for over 40 years and have never had any issues or viscosity breakdown. I’m a customer for life
