Change your oil. Save your engine

Best oil for long engine life. Even the most expensive motor oil is dirt cheap when compared to replacing an engine. I use this oil in my generators they run long and hot during summer storm power outages. Great synthetic oil that can take the heat.

Good Job Sam's, thanks for stocking Mobil 1 10w-30

Glad Sams sells the Mobil 1 10w-30 weight oil. I panicked when I was at another Sams store and they didn't have any of the 10w-30. I have a lot of vehicles and none of them use the 0-20w oil.

Best of the best

This is, in my opinion, the best motor oil on the market. I used it in a car which had over 90,000 miles when I decided to install some hotter cams. The lack of gunk and crud in the head was astonishing. It really keeps the engine clean, which enables it to last longer. If you lease a car, it isn't a big deal. If you buy a car and drive it until the wheels fall off this should help you get every mile out of that car.

Buy this oil.

Mobil 1 is the best oil you can buy. I have a 2007 Camry with 190,000 miles on it. I started using Mobil 1 since it was new, replacing it between 8,000 to 10,000 miles. It does not smoke, rattle, or leak. I also have been buying it from Sams. They have the best price anywhere. Believe me, I've shopped around, Sams has the best deal.

I use it once a year in all my cars

I started using Mobile 1 in the summer of 1987 in a 1986 Pontiac Fiero 2.8 liter V-6 after driving it 10,000 miles to seat the parts. I changed it typically every summer and did drive it slightly under 15K miles in each year. In 2000 I had a head gasket blow due to overheating because of a loss of coolant and had to remove the cylinder head. The cylinder wear had yielded a ridge on the cylinder tops that was barely detectable using a fingernail ! While the head was off and it would not be a major effort to remove the other head and change out the rings and bearings if needed, I pulled the pan to check the bearings. The main and rod bearings had no significant wear and most of the bearing surface was still gray and not even shined. This was after 150,000 miles!. I have used this oil in every car since I saw that. Almost no detectable wear after 150,000 miles and only summer oil changes! After each oil change the removed oil still felt greasy but normal oil seemed to feel watery if that makes any sense to you. Also for some reason I rarely had to add more than a quart during that entire year. In addition the cost is lower than for standard motor oil as it requires 1/4 to 1/5 as many oil changes!
