    Fixed my engine oil pressure light
    By  CURTIS,  a  Verified Buyer  from  Abilene, Texas  on  February 20, 2023
    Recently rebuilt a 2004 Dodge Dakota with a 3.7L engine. The engine had 148K coming out of a Jeep Liberty with no operational problems. Three thousand dollars later it is in my Dakota and I didn’t get the oil change to the installer soon enough so he put in a Brand-X 10W30. I ran it around town and out to the farm and it performed fine. Then I took a 100 mile trip and got a “oil pressure” light at highway miles near an overpass. Pulled over after killing the key. Oil was full and clean and the engine made no extra noises for the rest of the trip. Oil light would be off on start then come on during operations. So . . . I put in about two cups of Marvel Mystery oil and drive back the 100 miles staring at the light (ouch). Got my box with the filter and 5W30 signature oil and went strait to Pennzoil Lube. The engine was rattling a bit when I pulled up. The Band-X came out with much dark color but still looked clean on the stick. The AMSOIL filter and oil change made the engine purr like a kitten, and it has been ever since. Oil Pressure light went out.
    Bottom Line
    Yes, I would recommend this to a friend.

    No funnels and oil change gloves
    By  DaBusch,  a  Verified Buyer  from  Memphis  on  February 20, 2023
    The order was fine except they promised me funnels and gloves. When I used the codem they said it was not valid. So I ordered a kit. Then a few weeks laterm they sent me an email promising funnels and gloves IF I ordered more product. Fool me once, shame on you. Fool me twice, shame on me.
    Bottom Line
    Yes, I would recommend this to a friend.

    If you can afford it
    By  MICHAEL,  a  Verified Buyer  from  California   on  February 18, 2023
    This motor oil give me confidence in its protection but that’s only from what I’ve read about it. It’s outrageously expensive and it never goes on sale or offers rebates. Their prices only increase, so if you can afford it, it’s a good oil. I’m not sure if it’s twice as good as other premium synthetic oils that go on sale at half the price. Paying 100% more for something that’s 25% better is a choice you’ll have to make.
    Bottom Line
    Yes, I would recommend this to a friend.

I am sold on AMSOIL products.
