Works Great in 2015 Corolla ECO

Have a 2015 Corolla ECO with the CVT transmission with 4,000 miles. I had the factory oil changed at 3,000 miles at the Exxon-Mobil station. This vehicle MUST use 0W-20 synthetic according to Toyota. There is now almost no engine noise and fuel economy is about 44 mpg on the highway.

GREAT FOR ALL FLEET POLICE VEHICLES

I have been in charge of two different fleets at two different Sheriff's Office for the last 26 years and ALWAYS used Mobil 1 EP in every Ford Crown Vic, every PPV Tahoe and every single GM we have ever run. I cannot even imagine how many quarts, but thousands for sure and NEVER ONCE HAD AN ENGINE FAILURE! Change every 5K because of severe driving with Mobil 1 filters and have NEVER had an issue!!!! Will continue to use without question for many future oil changes!!!

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).

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.

The Best Oil From Mobil1 Extended Performance

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.

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.

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.
