I switched from conventional oil in my Toyota Sienna to Mobil 1 5/30 at roughly 70K. I now know that conventional oil can cause sludge build up. Sludge is not a friend of any motor. I change my oil every 5K and also install a new Mobil 1 filter. My oil comes out a dark golden color--not black like the dyno oil did. The van actually uses no oil in 5K. It now has 130,000 miles on it and runs like new.

I've used this product for 150,000 miles in my Acura TL, the car presently has 235,000 miles on the odometer. I pour the old oil back into the bottle and it fills it right back up to the top. The car doesn't use any oil over the 7,500 mile oil change interval. I use it in lawnmowers, snowblowers, generators, never had an oil related failure. Once I drained this oil out of my lawn mower and forgot to refill it, the engine ran for 5 min with no oil in it. The aluminum connecting rod seized to the crank but no damage to the rings. That's good oil.

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'm a 46 year old man that was turned onto Mobil 1 oil from my grandfather, they used Mobil 1 in all their fleet vehicles! After using Mobil 1, I can honestly say... I have never had Any internal engine failure on any vehicle I have owned! I only & strictly use Mobil 1 & wouldn't change to another product! In my opinion... I use only the best!

I first used Mobil 1 in my 1999 Toyota Camry, I used for 4 years, in 2019 I got 2007 Toyota Corolla till 2022 when I sold it with 32% increase of the original price, for 8 years I never experienced any engine issues. Mobil 1 has been safer and protector of All engine parts

I can't say enough good about the Mobile One synthetic oil. I started using it in my wife's 1990 Astro van and we drove it more than 250,000 miles on the original motor with no major repairs. Also, I bought a 1989 Astro van used with 89,000 miles on it and change it to Mobil one oil and drove the original motor over 365,000 miles. Presently drive a 2001 Astro van with over 400,000 mile, but its on its second engine, with 225,000 on the first engine, second engine with over 175,00 miles. I started using Mobil One because I drove over 3,000 miles a month and it was cost effective to use Mobile One and change the oil every 5,000 - 6,000 miles. I now use the extended oil and drive 15,000 miles to a oil change. I now have my whole family using Mobile One oil.

First car I used Mobil 1 in was a new 1978 Oldsmobile Cutlass Supreme. I faithfully changed the oil once a year, every year. When I sold the car 12 years later, the engine ran so smooth you couldn't tell that it was running when at idle. Never burned a drop of oil in 12 years. I have used it in every car/truck I have owned since. Currently using it in a 1999 VW Passat and a 2005 GMC Sierra 1500 - since both were new. If you value your engine, run it on Mobil 1.

I own 3 vehicles. A 1998 Chevy K1500 5.7 Vortec, a 2018 Ford Mustang 2.3 EcoBoost, and a 2016 GMC Sierra Denali 1500 6.2 Ecotec (0W-20). I’ve tested every major brand of motor oil there is on these vehicles and none of them came close to comparing to Mobil 1! I would highly recommend this product to anyone that feels like they could benefit from a strong and smooth engine!

Mobil 1 Full Synthetic 5W20 until 75,000 miles then Mobil 1 Full Synthetic 5W30. My wife's 2016 KIA SOUL would crank and run with no issues right up until someone hit her from behind on the Interstate and totaled her car. She was going about 55 mph and they were going at least 80 to 100 mph. The care was folded under, but the engine was running like normal while the Highway Patrol had to pry her out of the car and the Tow Truck guy had to open the hood and disable it to get the engine to stop running. My wife suffered no injuries. We went and purchased a new KIA SPORTAGE and are using Mobil 1 Full Synthetic Oil in it. Who ever buys that car for the engine is getting a solid KIA SOUL engine. At 200,000 miles we started using Mobil 1 Full Synthetic 20,000 mile oil. That Soul would crank and start like a new car. We have a 2001 Ford F-250 V-10 Triton Crew Cab and 2002 Ford F-250 5.4L Crew Cab 4X4 and they both are above 200,000 miles and we run Mobil 1 Full Synthetic 20,000 mile oil in them.

Hello, I have changed my daughters oil twice now and not even getting close to the guaranteed milege. The first change I only had 8K miles on it and the life was down to 15%, so I wasnt even going to get 10K out of it. I decided to give it a second chance since it was a brand new 2017 Honda H-RV, but the second change I only have 5K miles and the life was at 50% so I am going to be lucky to get 10K out of this change. I will definitely not be using this product again and will try another brand. And for the cost of this product, it should live up to its claims.
