I always come to Sams for my oil since they carry the fully synthetic oil at a great discounted price. It's great for me.

I've used mobile1 for 3 years without changing oil and it doesn't dry up until my maintenance requirement light showed up

I've been using Mobil 1 synthetic motor oils for approximately 30 years. Extremely satisfied with quality, performance and value. A brand you can trust.

Great price for 6 quarts

Good

Great oil for the price. Only buy it when it’s in sale. Could not find a cheaper price for six quarts of brand name full synthetic oil. I buy it in sale and stock up.

I've used Mobile 1 oils exclusively in my performance cars and daily drivers for years. It always comes out as clean as it went in, and never have had an issue with sludge. Definitely the best oil if you want to take care of your engine.

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!

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 .

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..
