Great for truck

Good price,mobile one.

Glad you sell motor oil!

This is good oil. With a $10 sale on a 6-pack of quarts, it was a reasonable price. The regular price is too high, which is why I took off one star.

The box came delivered all greasy with one or more of the bottles leaking out. It also came upside down by the shipping company. There wasn’t enough oil missing that we didn’t feel like returning it.

My girlfriend was so excited when the Fed-Ex man dropped off the box that had Sam’s on the outside. She thought it was some type of food that I ordered. She was disappointed when I opened the box up and she saw that it was motor oil. Good price for quality oil.

I've been using your product since it first came out in the 70's. Since introducing your high mileage brand 5w-30 it's been my go to oil for my 03 Subaru Outback. Works extremely well with one exception. (And this includes your regular synthetic oils) I tend to loose about 2 quarts between oil changes. I believe with the lubrication properties of this oil a percentage leaks by the rings and is consumed. I do not have any external leaks and I've had this problem with every car that I've used your oil in. This minor problem is far outweighed by the long lasting mileage I've gotten on all my engines.

I have used Mobile 1 for years in every motor I own. The proof is in results and I have a 2009 Chevy Silverado with 250,000 on it and all it has ever had is Mobil 1. I get the oil sampled once a year and the results have always been very good. I will never use another oil.

So far, so good. I've been using Mobil 1 for several years. Not any difference from the regular blend, as far as I can tell at this point. One thing I noticed after pouring it in, it is no longer carrying the SAE rating for my Chevy truck. Shouldn't make too much difference, I hope!!

I have been using Mobil 1 as long as I've owned the car, A Morgan Aero 8, with a BMW 4.4 L V-8. The only indication of oil performance is I have was at 65,000 miles I did a compression check and all cylinders measured 180-190 psi a sign that the rings and valves were doing their job. I never have to add oil between changes. I change oil and filter once a year, 5000-6000 miles. The car now has 77,000 miles and just completed the oil change.
