Great results with Mobil 1

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?

Engine sounds so quiet

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.

Keep turbo happy!

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).

Simply Great Lubrication

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 Synthetic is 2nd only to "Amsoil"

see above comment...Mobil #1 is the best oil available for enhanced engine protection w/ reasonable pricing associated with it after reading many on-line internet peer reviews....unlike "Amsoil" which is greatly overpriced for the additional unneeded over protection it provides.

Oil that last

I changed my oil on 2020 Equinox 1.5T before a 1500 mile road trip from NY to SC. I used 0w20, a week before trip. The engine was very smooth, avg 34 mpg at 75 mph. Dip stick shower full and upon return still showed full. Oil color after the drip was not dark or smell burnt. Plan to check oil levels once a wk and take oil down to 5% on OLM. I saw how M1 does test on their oil and have no doubt it can go that far. Use with confidence.

Mobil 1 Extend

I have been using Mobile 1 for 8 years now. The previous owner used Mobile 1 from the start. It's a 2006 Chevy Silverado with 243,000 miles on it. The oil is changed about every 12,000 miles and the filter is changed every 6,000. It uses about a quart of oil between filter changes.

Engines are strong and clean with M1 oil

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.

PAO group 4 base stock

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”
