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 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'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.

Been using this product along with the Mobil one oil filter in my 1997 Ford F150 since it was new has over 200,000 miles with no oil consumption, leaks, or smoking. Always changes oil every 7,500 miles. We had a boring machine at the place were I worked that took conventional oil and it gear box would get so hot you could touch it . Changed it out with synthetic oil and it would barely get warm that convinced me synthetic would make any mechanical device run cooler and last longer.

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.

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..

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.

Mobile one that speaks for it’s Self

This is the only oil I put in my cars, and you should to.

Great product at a very fair price
