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 .

Bought this quart to go with the gallon because my car holds 6 quarts of oil. Can’t beat the price as Walmart is half way cheaper than Advance auto and any other retailer around.. I would highly recommend checking Walmart before buying your next oil change.

I use Mobil Synthetics in all my engines, from lawn mowers to work vans, some of which are constantly in the elements of W PA, hot and humid summer and cold and snowy winters. Startups are quiet with oil pressure almost immediately. I have been able to extend my oil changes somewhat, and find the oil to be cleaner when I do the change. My perception is that the engines start and run smoother, run cooler, and less noise. I have even used it in some ventilating fan motors with sleeve bearings that had stopped. After working in the oil, the run quieter than when new, and coast longer!

5W-20 is specified in many newer vehicles, and it was not stocked in any of the local Sam’s Clubs near my Houston location. More specifically, I use Mobil 1 5W-20 in both of my vehicles and have checked often for it. Thankfully, Sam’s shipped it to my home without charging for shipping.

I’ve used Mobil 1 oil in all of my vehicles since 1978. Many of the vehicles were turbocharged, and while some were new, most were previously owned vehicles. All my oil changes were personally done by adhering to the manufacturer’s normal service mileage guidelines. I’m proud to say I never experienced any engine or turbo failures related to wear and tear, while using Mobil 1 oils. Additionally, I never experienced any oil seal leaks from using low viscosity synthetic Mobil 1 oils in my vehicles.

Proof is in the pudding! I've used Mobil 1 Synthetic oils in all my cars since the 80's. Some have been daily driver's with mileage well over 100,000 while others raced quite a bit both normally aspirated or forced induction. Never an engine failure and any internal engine inspections show little to no wear at all.

I've been using Mobil 1 in all of my vehicles for over 20 years and it provides superb lubrication and prolongs the lives of the engines in my vehicles. I do all of my own oil changes and use nothing else for engine oil. All of my vehicles have had over 250,000 miles on them when they were retired and one of my existing vehicles is approaching 220,000 and the other 193,000 and they both run like new. There is no oil leakage and none is burned between changes. About as close to a guarantee of engine longevity and reliability as you can get. I will use nothing else.

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 can't remember using anything but Mobil 1 since Mobil introduced it way back when. Used regular Mobil oil prior to that. I use Mobil 1 in every engine I own and have always been more the pleased with its performance. I have used it in Chevrolet pickups, BMWs, Toyota/Lexus SUVs, and all my lawn equipment. They are all happy, so, so am I.
