THE OIL I ORDERED WASNT SECURE AND WAS LEAKING OUT OF THE BOTTLE..LUCKILY, IT WAS IN PLASTIC BUT WHAT A MESS..

Use to buy a different oil but thought around the first of the year to try this Oil was even a little cheaper so I still use it

have used mobil 1 on all my vehicles Pontiac Bonneville 262,000 and counting Chev Malibu 158,000 and counting

Great oil for many years, motors go for at least 350,000 miles without even pulling the valve cover or replacing any parts.

Pretty good product im a pretty big nascar fan and getting to use the same oil as nascar is pretty cool

Good Stuff. I've used this for about ten years, maybe longer. Three different vehicles. Never a problem.

Right price. Lower than auto parts store. Local club was out of stock, free Plus delivery saves me a return trip.

I’ve been using Mobil-1 for many years. Walmart offers it at a very reasonable price. I use it on my 2013 Avalanche.

Mobil 1 oil at a great price, plus free shipping for us as Sam's Plus members. Great savings and convenient.

To me, Mobil 1 is by far the best oil to use in your vehicle. I purchased a 2003 Ford Ranger, 3.0L, 24K miles, the end of 2007, 4 + years old ! I changed the oil to Mobil 1, 5W-20 on the first oil change I did. The first thing I noticed was the engine appeared to run quieter ! Interesting. I can't say if the MPG improved, I didn't keep a record, but the engine did seem to run better overall. It is now 20 years later, still running Mobil 1, 5W-20, in the same 2003 Ranger, and the motor is still running great, no major repairs, starts every time I turn the key, still sounds great, you would never think I had the original motor in the truck. My secret is: 1) Full Oil/Filter changes every six months (twice a year - January and July). 2) Change the Filter in between the oil changes, three months intervals (April and Oct), and add Mobil 1 to top off the engine oil lost when changing the filters alone. 3) Start again Jan Oil/Filter change. It takes 4 Filters, Oil Filters of your choice, 2 Cartons of Mobil1 (six quarts in each carton, purchased at Costco, great price); 5 quarts of oil for the engine during the January and July oil changes, and an extra quart for the oil filter change (April and Oct). Simple RIGHT ! Cost: approximately $80.00 yearly. I know I could get far more milage on the oil... but more oil changes, is better in my book. Thanks for reading. NOTE: I am running Mobil 1 in my new Dodge and in my latest purchase a DR PowerEquip. XL30,20HP V-Twin Brush cutter, which I am expecting a long life on the motor.
