[This review was collected as part of a promotion.] I have used Mobil 1 for years.

Great price for 6 quarts compared to the 39.99 you spend for a 5 quart container

Yep. It's slippery oil.

Good

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 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.

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.

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 .

I am 78 years of age and have been using Mobil products for 50 years I have changed my oil at proper recommended intervals and have never had a engine problem. I change my oil filter each time the oil is changed. This oil synthetic or regular is the best on the market. I have owned more than 25 vehicles all different makes foreign and domestic noe engine problems that speaks for itself.

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!
