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 am an owner that only worries about my engine while I own my car. Reading an article about Mobile 1 (100,000 mile test with no oil change when introduced) I decided to only change oil myself every 100,000 miles. I did this thinking I would sell the vehicle before I changed oil. If I went over so be it as I added new oil as needed. The 1st car was a1960 283cu-inch Chevy Biscayne (Mobile 1 intro 1974) sold running good with original Mobile 1 in 2016 with 100,000 plus 12,000 speedo roll over miles. The 2nd car was a 93 Mazda MPV, purchased 2001 with 200,000 miles, filled with Mobile 1, then instructed my daughter to only add Mobile 1 when low and never let anyone change the oil. It was running great at 300,000 miles when a deer hit her and insurance totaled the car. New 97 Dodge caravan running well at 85,000 when traded for new 2005 Dodge caravan still in use and running well at 86,000 miles. Used 1996 Toyota Tacoma truck purchased 1999 (22,000 miles) still running well at 84,000 miles. Mobile 1 installed at acquisition and no oil change after that.

I’ve been using Mobil1 since introduced. I first saw Mobil synthetic oil used in multi-million GE aircraft engines I was flying in the late ‘70s. When I saw an article about it in Popular Science I knew I could use it with confidence. I was picking up my new Lexus from service in 1990 at Lexus of Alexandria, VA and a fellow waiting with me in the service drive for his car asked me how I liked my car. I dished about only using Mobil1 in all my cars. Turns out he was the CEO of Mobile. Small world and great oil...

I having been using Mobil 1 0W-40 in my car since I bought in 2011. I have done 10,000-mile interval oil changes and I just took my car into the dealership for the 135,000-mile checkup and they took it apart and I had no oil sludge anywhere to be found in my car. I love my car and I want to keep it FOREVER. With using Mobil 1 I trust and believe in their product and I will only use it in my car and future cars. I tell all my friends who have German cars to use Mobil 1 0W-40. It is a product the worth every penny. I had the dealership take pictures of my car when they did my 135,000-mile service so I could Have Proof that this oil works. This oil is the only oil I will ever use, It is the best. The people at Mobil 1 know exactly what they are doing, this is the BEST OIL EVER.

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.

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.

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.

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 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

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.
