I have been using Mobile 1 since the 1970’s. Knock on wood. I have never needed an engine repair because of oil related issues.

Changed oil and filter in our RV. 1 quart of oil is all I needed because I had 7 quarts. Also bought the oil filter. Price was normal.

My Lexus loves it

Good price, timely

Super price in 1 quart size meets my needs. I don't need 5 quart bottles and hate the surcharge for 1 quart containers. No pesky rebate forms to mess with either.

Mobile one is one of the best full synthetic oils. I use it in all my vehicles since day one. Example. I have a 2009 gmc truck I bought new in 2009 and now with 250,000 on it I have not had any problems or replaced anything one the Motor.. i will always use mobile one and I am a true believer in it..

Having used Mobil 1 in a snowblower because of the cold temperature operation I decided to try full synthetic instead of the synth blend I was using in my Camry V6. A Subaru which also requires 5w30 using the same synth blend, it was suggested by a Subaru mechanic to use full synthetic now that it is broken in. Decided not to stock 2 different oils of the same weight. So far, no difference in gas mileage or anything just less money in my checking account. Cam2 or Wolfs Head 5w30 synth blend is several dollars a quart cheaper.

I've been using Mobil one for 25 years. It's fantastic. I had a Chevrolet 350 c.i. engine for almost 21 years It had 517,000 mi. on it when I got rid of it. The engine was still running strong. (mobil 1 from the 1st oil change) That's why I will always use it .

Have to watch out for Walmart pricing, in the title it clearly says 1 Quart (Case of 6) but you are really actually only getting 1 quart. I know others who have gotten the case size but others including myself did not. I chatted with support they said it was a mistake on their website and only offered a partial refund. The 5 quart container is a much better deal anyways and if I had known that I was only receiving 6 quarts I wouldn't have even placed this order. I don't even really use Mobil 1 anymore because all of the other competition has caught up and are usually cheaper options. Mobil 1 is still an excellent oil but it's pricey when compared to the others that can do the same for less. Walmart support is so spotty with who you chat with, some have resolved the issue by having the remaining quarts shipped out but then others like myself are only offered a refund.

I bought a new 1994 for ranger with a 2.3 4cyl engine. I took it home from the dealership and immediately changed the oil to Mobil 1 full synthetic. I change the oil every 5 to 6 thousand miles. Now the truck has 300,000+ miles on it and still uses 1 qt of oil every 4k miles since it was new. Oil psi and not changed. I am not nice to this truck, I over load it all the time. I did crack a valve seat at about 250K miles and I fixed that myself (40+ years experience in auto industry). While the cyl head was off I noticed all 4 cylinders still have cross hatch showing in each cylinder and no ridge. All my rigs use Mobil 1 exclusively cars, Trucks, Motorcycles.... Also, I replace air filters every other oil change. Never once have I had an oil related issue with any of my vehicles.
