I’ve used Mobil 1 for years in all my cars. It’s important to me that my cars stay in top condition.

This was a good price on a great performance motor oil. I have used Mobil 1 synthetic in all my cars for many years. Hard to beat.

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.

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 have been using this oil for 6 years in 5k mile intervals and it’s been amazing. The weight is perfect for Florida weather but also performs really great in the cold. I’ve worked in a dealership with 5 European brands all of which use 0W-40 for specific cars. Highly recommend the product to anyone looking to use it on their own car.

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 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 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 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!

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.
