I recently traded a 1990 Acura Integra with the same friend I bought it from, for his 2003 SAAB 9-3 ARC 2.0T 6 speed. When I got it every oil change I did was as black as night. I change my oil religiously every 3,000 miles. Since the first day I got it I started using this oil (factory recommended) and 20k miles later the oil has barely changed color when I go to change it. Currently at 195,400 miles on the odometer. I’m am very pleased to see that the oil is indeed cleaning the engine as well as providing excellent lubrication.

I purchased my Jetta new in 2011. I change my oil every 10,000 regularly using only Mobil 1, 0W-40 and I am at 310,000 miles without any issues with my engine in all that time. I plan on going to 400,000+ miles. If I ever buy and new car I will definitely use Mobil 1 for that one as well.

I feel that if this oil is good enough to be an OEM oil for Mercedes I can run it in my VWs. I have ran this oil in 5 of my Volkswagens (2 with over 200K), 3 Mercedes(1 with over 300K), 4 other cars that I maintain for friends and family and have always had good luck with this oil. I run 5K intervals on my turbocharged cars and 10K on my NA Mercedes and VWs and have never had issues in terms of engine wear or oil consumption.

I've been using this oil in my 04 BMW325i Wagon since it was new and it has over 200k miles on it now and the engine still runs as new. I use it in my Porsche and Mercedes too.

using it every 13 k miles on my Audi A4 Quattro 2000, imagine an 17 year old engine still running like new, going to keep using this oil for a long time.

I've religiously maintained Mobil-1 0W-40 in my 2010 Mercedes-Benz S550 5.5L, changing the oil at every 10K miles. Now at 320K miles on the odometer, I've still yet to experience any lubrication wear issues from the engine.

I like my rides clean if you know what I mean, tip to tail and in between. Having Mobil 1 in the engine means I can have peace of mind that my ride can perform at its best.

Have been running Mobil 1 0w-40 in my Ford for the last 6 years. I have found that it makes the car run very smoothly and it seems to handle the heat generated by the turbocharger really well..Highly recommend Mobil.

i have a BMW that has a v8 known for oil cosumption. It keeps the leaks in check.Even though it calls for 5w-30 i use this instead. For the price, you cannot beat it. In my opinion, its right on par with LiquiMoly at half the price

service is poor. sam's doesn't keep this oil in the store. they don't have 0w20 available for shipping, so if you need both they will charge you $8.00 for shipping because the total would be less than $50.00. I have been a plus member for years and shipping used to be free. recently the cost of plus membership has gone up and "free" shipping is now qualified. both oils are stocked mutually exclusively. this stinks!
