truck motor seems quieter after oil change and mileage increased 2 MPG for the first 500 miles so far.

Mobil 1 is the best oil for today's modern high performance engines. I always stock up when it goes on sale at Sam's.

I’ve been using Mobil 1 in all of my vehicles and tractor for the past 30 years. Never any engine issues.

[This review was collected as part of a promotion.] it was affordable and easy to find and it's a good brand

Been using and trusting Mobil 1 5W-30 for over 30 years in all my cars and trucks and not once had any engine problems or failures. Great product.

No issues with this oil. My truck has run on it since new and still runs like new after 57000 miles.

Its a solid oil. Full synthetic is what is required in multiple vehicles i own and ive been running it for close to a decade with no issues.

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.

Great oil. The only oil I use in my special cars.

Fast shipping and good quality
