I am a retired NIASE Certified Mechanic and operated a Mobil dealership when Mobil 1 first came out. I have been using Mobil 1 in my cars and trucks ever since and have never had an engine issue with any of them. I can say the same for any customers I had that used Mobil 1. From a customer that owned a Rolls Royce and a Lamborghini, to a customer with a VW Rabbit, once they tried it they never went back to conventional oil.

Got a 2015 Honda CIvic, little over 45000 miles and has been using 0w-20 Advanced from the beginning. Have been very diligent on changing the oil and has been doing so about every 5000-5500 miles (going by the car's oil life sensor). Thought I give this one a try and really didn't see any huge difference. Currently at 6000 and my oil life sensor is at 5%. Driving conditions & characteristics have not changed but it seems like I only got 500 more miles out of it. Didn't really see any improvement compared to the Advanced fuel economy. Disappointed.

I’ve been using Mobile 1 for about 20 years now. Been using it on my 2002 F150 since new and still own it with 135,000 miles. Used it on my 2008 Honda Accord since new till November of 2020 when it was totaled in an accident with 165,000 miles. Use it on my wife’s 2015 Toyota Highlander since new and has 81,000 miles. Finally on my 2017 Lexus IS200T with 35,000 miles. Great motor oil!

2016 Accord Sport with direct injected engine seems to love the Mobil1 Extended Performance 0W-20 What I like about it: - Less oil consumption compared to some other 0W-20 synthetic oils including Mobil Advanced Fuel Economy after 5,000 miles of severe driving - Seems to be a more robust stay in grade formulation offering better engine protection which should not change consistency over the oil life monitor in my car which is "very important" especially in these newer Direct Injected and Turbo engines. - Meets car manufacture API specs including SN, SN-RC, SN Plus (regardless of the marking on the label) since 2010 - Engine seems to be a little more quiet on this oil versus Mobil1 Advanced Fuel Economy 0W-20 or my brain is playing tricks on me - When my oil life monitor says to change the oil, the Mobil 1 EP is probably at half of its life so, no risk of damaging the engine if you go down to zero percent or need a few days to get into the service department - Few extra dollars for better protection can't be beat - Only downfall is the Mobil 1 Advanced Fuel Economy 0W-20 seems to give a little better fuel economy (1 MPG) however, I'll take the better engine protection with the Extended Performance all day long Perfect oil for my Honda, it loves this stuff!

I've been using Mobil 1 Extended Performance 0W20 with Mobil 1 oil filter's for 5 years on my 2019 Honda Insight. My car still runs great, it still feels new. My engine gets great gas mileage and performance. I change the oil every 5,000 miles with a fresh Mobil 1 oil filter. I'd recommend Mobil 1 products to anyone looking to take good care of their cars. I'd recommend always coupling the Mobil 1 oil with a Mobil 1 oil filter to get maximum protection.

Just switched from Mobil 1 0W - 40 to 0W - 20 extended 15,000 mile protection. Spent 20 minutes finding the only FRAM filter for our 2006 Saab 95 because the shelf at Walmart had everything messily scrambled together. Got to register....my filter accidentally taken by cashier and put into checkout of previous customer. I was very frustrated but ended up being a good thing. Went to Autozone picked up Mobil 1 filter as replacement. When I removed the FRAM filter and compared to Mobil 1 filter I was surprised. The FRAM filter had a skimpy narrow rubber gasket which was as hard as a rock after 3500 miles, the new Mobil 1 filter had a beefy thick noticeably wider robust gasket seal. I have always been having some leaking from the FRAM filters, but I liked those because of the finger friction grip material they add to cap of filter. However, the Mobil 1 filter was much higher quality I’ll buy a oil filter removal socket instead. I have used Mobil 1 in the Saab now 4 cylinder turbo 138,000 miles, and my Chevy Avalanche at V8 5.3L 180,000 miles with no major engine reapairs. The only repairs on the Chevy was engine tune up at 120, 000 miles, alternator and water pump which had nothing to do with internal engine lubricant. The SAAB has had only the ignition module that wore out at 100,000 miles, a vacuum tube, and the valve cover gasket.....again unrelated to internal engine lubrication. I also use the Mobil 1 10w - 30 in my tractor, mowers, and snowblowers. Who needs to replace or rebuild and engine....I have too many other things in life to spend my hard earned money on. Use Mobil 1 products!

I have been using Mobile 1 Extended Performance 0W-20 oil since Day One. After 286k miles our 2009 Hyundai Sonata runs like the day it was new. I change oil and filter every 6-7k miles. The engine runs so silently I often turn the key to start by accident when the car is running. There are no leaks, although we do add a half quart between changes sometimes. Maybe someday we'll switch to Mobil 1 High Mileage but certainly not until something changes. I cannot recommend this product highly enough!

Like a few others on here, I also tried both Pennzoil Platinum (5W20), and the hard to find, more expensive, Ultra Platinum. I noticed in our 4 cyl. Jeep, the lifters would clatter loudly on a cold start up, whereas that never happened with Mobil 1 EP. I quickly switched back to M1 EP. Also used 5W20 in my 15+ y/o 5.7 Hemi with great success. Had over 125K miles when traded in. Plan to use 0W20 in new 3.6 Durango.

I was hesitant to use such a thin oil in my Honda Element with 140K miles, but both Honda and the Mobil 1 oil selector recommended the 0w-20 Mobil 1 EP so changed it from 5w-20 which I have been using since the car was new. After about 2500 miles(in 90F+ summer) using 0w-20 Mobil 1 EP, no oil consumption, but the color turned very dark. Surprisingly the fuel mileage dropped from 21city/25hwy to 20city/24hwy. This is strange as the 0w-20 is touted to be more fuel efficient than the 5w-20.

I have been using M1 EP 0/20 and M1 oil filters since my 2010 Corolla was brand new. It sadly got totaled when I hit a deer several months ago. I changed the oil and filter myself every 5-6000 miles the car consistently got 26-32mpg city and 32-40 highway. It was a 5speed manual. The car had 284,000 miles when it was totaled. It never burned any oil till 250,000 miles. 1/2 qt between oil changes. The engine ran perfect at 284,000 miles. But the giant buck I hit was too tough for the plastic and sheet metal of my beloved Corolla. I loved that car. I miss that car.
