    The Only Oil I Use. Number 1 for Mobil 1.
    The only oil I use in my cars and suv. My suv has close to 170,000 miles and I've been using Mobile 1 since 40,000 miles. What's funny is that for what Walmart sells this oil and filter, you'll pay almost $20.00 more at the auto part store.

    Ext Perf 5W-30 Gives my Car Added Protection.
    Extended Performance 5W-30 gives me a feeling of confidence. I change oil, filter (Mobil 1), and rotate tires every 5000 miles. Mobile 1 Extended Performance has my engine covered in the event I go over a few miles since it is rated for 20,000 miles

    Unbeatable price, but close to zero stock in store
    I bought these (3) 5 Quart bottles of this Mobil 1 oil for about $10 less, PER BOTTLE, than places like NAPA, or Auto Zone. Then it was delivered for free on top of it. There was almost ZERO Stock of ALL oil in the store, as I tried to buy it at a store, 2 in fact, so just went online to Walmart.

    MOBIL 1 - DON'T LEAVE HOME WITHOUT IT
    Mobil 1 has kept the engines in my cars running like new and my cars are not new. I'm a car guy and maintain 8 vehicles with Mobil 1 for me and my family (six drivers). This includes a van, five SUVs, a sedan and a high performance sports car. Years range from 2001 to 2015 and odometers range from 35k to 250k. No engine failures, oil leaks, or burning of oil. If for some reason and oil change is extended due to the vehicle being remote than this is the oil you want in that engine, I never worry about Mobil 1 letting me down because I've used it for over 25 years. I'm a F1 fan and my favorite team also uses Mobil1

    I use it in all my vehicles.
    I use Mobil 1 synthetic in all my vehicles, my Jeep, Journey, dual sport bike and the RV. I tow the Jeep on camping trips and have never had a worry about the oil breaking down while traveling through Calif, Arizona, Utah and Idaho in some very warm weather.

    One of the best oils you can buy
    I have been using this oil for years and the additional cost is what I consider cheap insurance for the longevity of my engine.

    BEST PRICE, FAST DELIVERY, highest quality oil
    Walmart has the best price anywhere on this oil, and it's fast delivery every time I buy this from Walmart, and I buy this about 4 times/year. The viscosity is what is recommended by manufacturer for certain vehicles, but it stays cleaner longer than any other oil. I service 10 vehicles, farm and family.

    Good oil but I received used jug!
    The extended performance is great oil. I bought 8 jugs from Walmart and they delivered 7 new jugs and 1 returned dirty black used open jug! The opened lid wasn't even on tight and it spilled used dirty black oil in my trunk! Check your jug as soon as you receive, lowlifes returning dirty oil these days.

    A Really Good Oil
    I have been using Mobil 1 Extended Performance Full Synthetic Motor Oil for more than 10 years in various autos that I have had. I have never had an engine/oil problem with any of my vehicles. My Astrovan had 250,000 miles on it when it finally disintegrated (body/frame). One of my current rides, a Subaru Forester 2.5L Turbo has 170,000 miles on it and is still going strong. When I change my oil I also change the oil filter, cabin filter, and air filter. Maintenance is the key to longevity with your vehicle and a really good oil is the key to reduced engine problems. I highly recommend this product.

    Great value
    Been using Mobile 1 full synthetic motor oil for years and never had a problem. Has kept my motor running smooth. The 5 qt container is usually the best value.

    Mobil 1 verses Amsoil
    Changed over from Amsoil after years due to drastic price increases ,Amsoil is getting too many middle men which is just making their product non-competetive.

    Good product at a good price
    Of course I cannot say it is doing a better job protecting, since I am not testing in a lab. I can however tell you, you can get better mileage using any synthetic over conventional oil. I my 8.1L gas truck, it made a 1mpg difference. (that is pretty big, since it only gets 13mpg) Make sure you have an extended life filter, if you plan on extending your oil changes. This is the most important piece. Most oil will last longer than the recommended change interval, but the filter is the part that fills up and can cause trouble. I hope this helps
