It’s Mobile One. The Brand Says it All!
Size: 5 Quart (Pack of 2), Style: Full Synthetic, Configuration: 0W-40
I buy Mobil One 0W-40 Full Synthetic European Blend Motor oil for my three older, higher mileage Mercedes SUVs. Considering all the vehicles are running well to this day speaks to the quality of their ongoing maintenance and Mobil One lubricants have always been part of their routine. Mobil One long ago became the favored brand of both European luxury car manufacturers and their customers. I’m no exception. The product comes in a convenient handled bottle that’s easy to pour without drips or spills. It’s built in fluid level gauge provides you with a real time window into the quantity of oil you pour and quantity remaining in its container.
The oil is an excellent lubricant and it’s great for my motor, too.
Price wise, it’s a premium offering from a premium brand. Even so, it’s worth every penny for helping keep my vehicles running as they were engineered.
I have no complaints with Mobile One and I don’t have a reason to change. I’ll keep buying it until something better comes along.

Mercedes certified - this oil is very nice, no need to drop loads on oil from MB or the other pricier brands, this stuff works very well.

Works great never had a problem
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
I've been using this mobile one in my 2005 Mercedes kompressor C230 w203 1.8 engine for about 18 years and never had a problem so I will continue to use it. The price was very good compared to other places but I did have to order one extra quart, I don't know why they don't make this mobile one in a six quart jug.

Great for my hot rod!
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
Perfect oil for my hot rod! Add a bottle of zinc and you get great low temp flow as well as good heat protection. As a 0W it flows quickly for good start up protection and the 40W means I get good protection as temps rise. My car has a flat tappet hydraulic cam so I add a bottle of zinc. Has worked great!
