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.

Was using CAM2 5w40, but it's performance was average, but better than the Castrol 5w40 in some respects - the CAM2 didn't get black as fast and didn't burn-off as quick as the Castrol. I evacuated all old oil and added the Mobil 1 0w40. The car started smoother, felt more responsive and mpg gauge was incredible! I was getting very good mileage - much higher mpg than what I was getting after a fresh oil change with the other oils I was using.

First time I used Mobil 1 on my 86' Porsche Carrera I was surprised to find that the oil pressure settled down into its fully warmed proper range within 60 seconds of starting the engine from cold in cold winter. This was something that took ten or more min. with my previous oil fill. Seeing that most engine wear happens when oil is cold before it warms into its normal range of viscosity and the Mobil 1 oil moves into the proper range very quickly from cold I have continued to use it ever since in my cars. I know when it needs to be changed on my very hot running air cooled engines where the engines use little to no oil until about six or seven thousand miles on the oil change at which time it begins to consume a little oil. This prompts me to do an oil change under the theory that the oil's additive package is starting to not function when oil consumption increases.

I've been using Mobil 1 0w40 on my 2003 Mercedes E320 since the day I bought it and currently at 259,000 miles the engine still runs great, doesn't burn or leak a single drop of oil and doesn't have any ticking noise. Last month i checked the cylinders with a borescope and to my surprise the crosshatches from the factory were still visible on the cylinder walls! Proof of a very superior oil! Here's to another 100,000 miles!

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 have use Mobil1 since 1986 in my Volvo engine and it is the only oil that i can accept to my car. Under oil cap and under valve cover, i can see the very clean, very shine engine. No any sludge, and no dirty. Engine is clean like new. My engine have more than 372000 miles behind, and it still works very well. No leaks, no problems with valves, no emission problems. Even when cold start, engine does not sound bad. So this is oil that i can trust, every day, cold or hot temprature.

Anyone that is is driving MBUSA anywhere in the world,i tell you to stick to mobile 1 engine oil cos they work well.I leave in Nigeria and the temperature of the sun is so high that the oil keeps the engine of my MBUSA normal and runs smooth. The european knows how to make a car run for a long by using mobile 1 engine oil.MOBILE 1 IS THE BEST engine oil so far both normal,performance and racing cars. I dont see any oil that can beat Mobile 1.

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 have been using mobile 1 0w40 for the past 130k miles in my Audi Inline 5 turbo. It now has 344k miles, original engine, original turbo. I did a valve cover gasket replacement lately and the engine was basically brand new. Look at the photos if you don’t believe me. Hardly any wear in the camshafts!

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
