The best oil ever, have been using this product for years

I buy this 5w30 for my 2019 gmc 6.2L the 0w20 is garbage and should never be recommended unless you live in nome AK.

I use Mobile 1 Extended performance on all my vehicles diesel and gas. I personally have never had an issue with any engine while using Mobil 1. It keeps my vehicles running smooth and like new.

My son has a 2000 Honda accord it had 52000 miles on it when I got the car and I heard a lot about Mobil 1 so I changed the oil with Mobil1 5w 30....went 5000 miles till oil change everything looked good...put same oil back in and now its leaks a little around front of motor and around filter everything is tight...

I usually use amsoil products but couldn't get it this time and was already past due on this service. So I figured I would try mobile one. Bought the 20,000 mile 5 quart jug of oil and the matching 20,000 mile filter. Performed the oil change and filled it up with oil. I poured In 4.5 gallons of your 5 quart jug and my car was still way low. Finished pouring in the rest and it was still low!!!!!! The car is a Nissan rogue with a 2.4 liter 4 cylinder engine that only holds 4.8 quarts of oil!!!!!!!!!!!!!!! I have owned this car for 3 years and this sure isn't my first oil change on this car or in my life. Been a professional mechanic for 23 years. Had to go a buy a couple more quarts of your oil. What's up with that. Probably wont use your products again after this. Unless you feel the need to make it right which I am highly doubtful you will.

I have a 1995 Toyota Camry LE V6. I've used Mobil 1 since day one. About three years ago I switched to Mobil 1 Extended Performance Oil because I started driving longer distances. The oil has held up really well and keeps my engine's moving parts clean. I know because my mechanic changed my head gasket and told me so. I also use Mobil 1 oil filters to match the extended protection of the oil since most oil filters only protect up to 7.500 miles. I love this oil and so does my car.

In June 2019 I changed the oil in the gas engine of 2013 Chevy Volt using M1 EP and a M1 filter. The gas engine in the Volt only runs when the battery reaches its minimum state of charge. Most of my driving is within the battery range, and as a result, the engine ran for less than 350 miles in the 2 year period. But the battery life monitor in the car just indicated it is due for a change due to elapsed time, so I am draining the "old" oil that is a clean as new, and refilling with the same product again and a new M1 filter. Since this will probably again be a long interval, I am quite comfortable using the Extended Performance oil and the premium filter to protect an engine that is idle for long periods.

I have 2 Chevys, a 2001 Silverado with a 5.3 and a 2014 Corvette with the 6.2 LT1. Both vehicles get Mobil 1 EP. The Silverado's 5.3 is incredible over 400,000 miles and no oil usage, and I am the original owner. Mobil 1 Extended Protection was not available when the truck was new- we used regular Mobil 1 back then. When the Extended Protection became available, we switched. We are aware of the extended intervals, but still drop the oil every 5,000 miles. We look at it as the absolute best synthetic oil out there, and since we have over 400K on it without a rebuild, we must be doing something right. We only put about 3,000 miles a year on the Corvette (due to hibernation in the winter months). We use 5W30 Mobil EP because of the quality. We believe frequent synthetic oil changes are the most cost effective insurance a owner can perform on their cars and trucks. At this rate, when the Corvette hits 400,000 miles, it should be about 130 years old and still running strong.

Let me explain by this: I have two cars; one is a 2006 Infiniti G35 that my wife rides and the other is my daily, 98 Buick Lesabre. my wife does not know anything about the cars. I mostly use Pennzoil but this time I preferred that one. My wife drove the car somewhere and when she came back home asked me: did you fix something on the car? It runs very smooth and silent. I will definitely keep using that oil.

I drive 20,000+ miles a year and started using Mobil 1 at about 115,000. My engine is smoother and quieter than it has ever been. Change oil about every 12,000 miles and it comes out dirty, but no sludge like I used to see. Very happy with the performance and mileage I receive while using this product. My vehicle now has over 186,000 miles on it and moving right along. Why not spend the extra few bucks for a product that you know is the best.
