I have used Mobil 1 Extended life for over 30 years with great results. I go to 20k miles on my vehicles. I have also used on my small engines and really like the results: No oil loss compared with the conventional oils and a much cleaner color after use. Question: What is the best oil for my new BMW with the B58 engine that calls for the BMW proprietary oil?

I've used this twice in my 2021 Hyundai Elantra. I immediately noticed each time how quiet the car runs right after Mobil 1 EP 0W-20 is used. I never noticed that when the dealer changed it using another brand. I always thought the engine might sound quieter if the oil hadn't been changed in a long time, but no just changing to Mobil 1 really does make it sound smoother.

Been using Mobil 1 since my first car, now as a professional ASE Certified Master Technician, its still all I use.

I just purchased an sUV with a turbo charged 4cylincer engine. Is there a 0W-20 Mobile 1 synthetic oil that is best for my application? I'm mostly concerned about the protection of the turbocharger bearing(s).

I began using Mobil 1 oil when I took a job working as a lubrication “chemist”. I was not a R&D pro, but had technical skills from other scientific disciplines and was charged with buying equipment and starting a lab. I had lots to read, learn and understand but was quickly impressed that virtually all synthetic oil manufacturers would compare their products to Mobil 1. (All trying to measure up and catch up). I retired 13 years ago and have no reason to change from the brand that I trust.

Mobil 1 is the ONLY oil I will use. This Extended Performance is even better than the original. At 10,000 miles the oil still looks new and is at the full mark. I've never gone the full 20,000 miles, but I'm sure it would easily make it. I use this in my wife's 2015 Honda Accord. BTW, I use their new Hybrid Synthetic in my 2022 Ford Maverick.

I love Mobil1 Extended Performance. its have triple protection and last longer performance. I leave it in my car for the full 15,000 miles with no worries. I had a 2010 Lexus RX350 that I got 150,000 miles changing at 15,000 mile intervals, Please always check your engine oil capacity should be full oil in engine for best protection, which was the maximum at that time. I wish it will have more promotions deals.

Mobile1 synthetic oil has been used in all my Toyota vehicles. Several of them are now more than 150K miles, but inside of the engines are still very clean seems like it's new (I checked it careful while when the valve cover gasket was replaced, for 2000 Sienna and 2003 Camry SE). You can tell if the oil is good (or not) only when you disassemble the engine after it passed 100K miles. Thanks for reading.

Mobil 1 Extended Performance has been in my vehicles since it became available. My current vehicle is a Chevrolet Equinox. It is the 1.5L with a turbo. Turbos are maintained most effectively with high quality motor oil. Mobil 1 Extended Performance gives my vehicle the best protection, and I know that I have a quality product from past experiences.

I have come to learn that Mobil is not using PAO group 4 in many of their oils like they use to. Please reconsider your position on this point. Mobil could then advertise and put on the bottle, “contains group 4 oil a true synthetic base stock”
