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.
