I have a 1999 Pontiac Trans Am WS6 with 114k miles. I just pulled the motor for some upgrades and I couldn't believe how clean the internals were. This is the first time this motor has been opened up. It's never been cleaned, flushed, etc. It has, however, never had anything but Mobil 1 Synthetic in it. After my experience so far, it'll never have anything else in it either.

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!

My wife and I just purchased our own house. So with home ownership we have been thinking about how we can save money one of the ways is to start doing our own oil changes. But after going over the mileage and needing a oil change we stopped in at our local Mobil 1 and was greeted by the manager John who not only had his team give us a much needed change but did it with a level of customer service we thought didn't exist anymore . I am more than capable of doing my own oil change now that I have the space but after going to this clean well maintained well managed location I will defiantly be doing my oil changes there. customer service goes a long way in my book. thank you John and your team.

I have 345,000 plus miles on my 2007 Nissan Altima se, which was put in when my car first hit 10,000 miles!, this oil is second to no other as my car purrs like a kitten even after running my car with no oil on the dipstick several times, I do not recommend doing that but my belief is if I had anything but mobile 1 in its crankcase, that I would of been shopping for a new car, thanks mobile 1 , jerry b.

My 03 Camry with 2.4L topped 360000 miles this week engine gets the same milage as it did new. The car uses no oil between changes and when I replaced the cam cover gasket the engine was spotless inside. I have used the 5w-30 since the car reached 5000 miles.

I've been using exclusively Mobil 1 full synthetic (5W30 and 5W20) in every vehicle I own and many others that I maintain on a regular basis since my dad taught me how to change oil nearly 20 years ago now. Simply put when performance and protection matter this is your best option for engine lubricant. The wear protection is second to none and you never have to worry about whether or not an OEM will question the oil if there is a warranty issue because this product is better than theirs or is their recommended choice for their premium vehicles. They also have great racing lubricants for protection under the most extreme and demanding of conditions. I am a believer in using this oil if you value protecting your vehicle's engine past the warranty period and want to see vehicles reach or exceed their engine's max service life.

I have used Mobil 1 for many years in everything from autos to motorcycles, lawn mowers, snow blowers, firearms, etc. It has generally kept my machines running long and strong. It also lasts at least 2x as long as dino oil. Just make sure to use a proper oil filter for long life synthetics.

Have been completely satisfied with my jeep's performance using Mobil 1. It's a dependable product that provides the wear protection for my 1997 jeep. I run 33" tires on a 4 banger engine, it's a lot to push that less than perfect aerodynamic vehicle on the highways. But can depend on getting the best performance from this product.

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.

Didn't know oil was dripping out the side of my oil filter. I had skipped my routine of checking oil, coolant, etc. a couple of times. When I did check my fluids found the dipstick dry.. I couldnt believe it! Ive been fooling around with cars all of my life and this has never happened before. I know wnough to say if it wasnt fir the lubricating properties of Mobil 1 Advanced Formula, I would probably be searching online for a new motor for my Ram 1500. I will use this oil for the rest of my time here on earth. I dont usually write reviews but had to on this one. Btw: added four quarts of oil then found the leak. No oil warning light, no symptoms of oil being that low. Scared the living daylights out of me! Thanks for making such a fine product Mobil 1. Im your new lifetime customer, for sure.
