I keep my 4 Kia Soul on for practically 24 hours! I bought my car with 13,000 miles on it! 15 months later I have 21,000 miles on it. I keep my car idle most of the day and often at night. I drive about 300 miles a day. I drive for Lyft & Uber. Plus I use my air conditioner all day in California and at night. I never treated any car I owned like I treat this one. So far this car has been dependable and reliable. I change the oil every 2-3 months. I don't think any of my former cars could take this kind of abuse! Only my tires do I expect to change in about a year! I been using Mobil 1 when it first came out I think around 1977! ( I could be wrong ).

Been a fan of a competitor for some time, availability led me to switching to mobile 1. Right away I've noticed smoother operation, which is debatable, but what isn't is the better fuel economy our vehicles have picked up. I'd swear our vehicles have more power and even running the air conditioning we get a 1-2 mpg improvement. So far, I'm very impressed!

Mobil1 5W-30 full synthetic with Dexos SN Plus is really an amazing motor oil. I tried it in both my Mercedes sedan and wife's GLE. It works much better than whatever 5W-40 the dealership had been putting in before. I noticed my engine heat gauge runs 1 tick mark lower that where it usually is and gets slightly better fuel economy.

I was a firm believer in this oil and was very proud to tell people I was a user of Mobil 1 full synthetic! That is until I recently got a bad lifter tick and pulled the valley and valve covers off of my 2003 5.3 liter Silverado and seen the god awful gunk build up! It was unreal! Definitely not what I was expecting after spending good money on what I thought was great oil. I would not go over 6,000 miles between oil changes. I have built a fresh 5.3 and I will be using AMSOIL!!!!!

proof is in the miles. my2003Ford Ranger4.0 just turned 174,500plus miles with this oil. used wix filters until high mileage mobil 1 filter became readily available 125, 000 miles were in dallas , tx traffic and hot texas weather,balance in Missouri weather since retiring. still no oil consumption or leaks, gives me20- 22 mpg, 5spd, 4x4 with 4.10 gears. use same oil in my john Deere 445 lawn tractor, john deere4x6 gator, new scaggs turf tiger zero turn mower and new ford f150 4x4 eco boost 3.5 whichjust turned 35,000 miles, with no consumption, As a side note, use 5W40 mobil1 in my 65 hp john deere turbo diesel 5320 tractor, just turned over1000 hrs.with no oil consumption. my wife's Toyota Avalon 2014, run 0W20 mobil1 with mobil1 filter, change oil once a year, usually just a bit over 10,000 miles. does not us a drop of oil, currently at 50,000 plus, will change after bad weather is out of here , southwest missouri . current oil still looks clean on dip stick. gave us 35mgp round trip to Dallas, tx, over thanksgiving nearly 900 miles on the road. why use any other oil, as is readily available even in rural Missouri.

I was first introduced to Mobil 1 synthetic with my previous car - 2008 Corvette. After a disappointing oil change at a local Subaru dealer I decided to do it myself. Although the car manual recommends a viscosity of 0W-20 I decided to use 5W-30 since the temperatures in Hawaii are more towards the warm temperature range. First drive after the oil change I immediately noticed an increase in power/torque; not a lot, but very noticeable. For those that know the reputation of this car not having enough power - this was a welcome boost. I also noticed after a day of driving that my MPG increased by 0.2 MPG per the dashboard display. I suspect that number will increase as more miles are driven with this oil. My advice: switch to Mobil synthetic NOW!

Been using Mobil 1 5W30 in my '12 Sentra SE-R Spec V since I bought the car new. Was using the over priced Nismo oil filter for the first couple years then switched to the Mobil 1 oil filter when there was a sale for a pack of 12. The car is sitting at 106000 miles right now and have done the oil change ever 6k, give or take a few hundred miles. Still runs like she did when I first picked her up with 6 miles on the tach. Recently took it to the dyno and is making 176 horsepower at the wheel and 170lb-ft of Torque all stock. Thanks again Mobil for making a terrific product, you will have me as a life long customer for sure.

I have used Mobil 1 for over 10 years on my 2008 Honda Civic. The vehicle now has over 340,000 miles! I have tried a few oils during that time frame, and I always come back to Mobil 1. For most of the car’s life it has used Mobil 1. After using Mobil 1, the engine seems more responsive. The Mobil 1 filter also ensures peace of mind, as you can extend your oil change interval. I usually change my oil every 5,000 miles. I would be highly interested in doing a commercial for Mobil 1 once my car hits 600,000 miles!!!! Thank you Mobil 1!

I have a 2012 Silverado 4.8 with a few mods in the engine tune long tube headers and a camaro ss body throttle I was recommended by the guy who tune the truck and this full advance synthetic oil is amazing the engine runs way smoother and I got 117250 miles on it it responds way better now than it use to not only that I change to the mobil 1 oil filter that too is a good product I will highly recommended and there no way I change the brand no more on the truck. Mobil 1 oil and there filters are the best.

I drove for a limo company back in the 80's., and my boss used Mobil 1 in all of the vehicles, even his own personal vehicle. Back then even before the new extended performance oil he would change the oil every 15,000 miles. and never experienced an engine oil problem. I saw with my own eyes, these vehicles go 300-400,000 miles and still be running great when he sold them. i have used Mobil 1 products ever since.
