I use M1 0-40 in two Mercedes because that's what Mercedes recommends and that recommendation has never let me down. I also use M1 5w40 in my Porsche notwithstanding the naysayers on Porsche blogs.

Oil quality is outstanding, here no need any reviews! About Sam's club - I was very surprised with specific product price and wide variety of growing inventory list. Definitely will be back here first in search for my future needs!

New Corvette owner and I am very pleased that GM continues their partnership with Mobil 1 by using this great product as a factory fill. Nothing runs smoother, cleaner, quieter and offers more long term protection than Mobil 1. I will continue to use this product for the life of the car. I am also happy to see Mobil 1 as a sponsor of the new Corvette C8R race car that will debut in January at the 24 hours of Daytona.. Thank you for making such a great product

Great deal!

It the only brand I use for my Mercedez Benz,

Independent tests show this oil prevents wear better than any other regularly marketed oil.

Sam's offers the best quality products in this country and when it is offered at a discount and you need it, take advantage of it.

Recommendation by Mercedes-Benz dealer and by some European car dealer, use this brand for long time never have any problem.

I’ve used Mobil 1 for years in all my cars. It’s important to me that my cars stay in top condition.

Excellent choice for BMW 335i. Provides viscosity andengine requirements directed by BMW for LL01 vehicles.
