    By  ANGEL,  a  Verified Buyer  from  USA  on  February 26, 2021

    The motor oil I recently purchased from AmsOil was 0W-30. It does a great job keeping the vehicle engine alive and running nice and smooth.

    Best engine oil you can buy.
    By  sam,  a  Verified Buyer  from  Phoenix, Arizona  on  February 25, 2021

    Describe the issue

    Best engine oil you can buy. It holds up to the heat during summer when it's 110 degrees in Phoenix. Switch to Amsoil Signature Transmission fluid as well. My Infiniti G37 runs 30 degrees cooler and getting 4 more MPG's with both engine and transmission fluid from Amsoil. WHY would you not switch???
    Bottom Line
    Yes, I would recommend this to a friend.

    Why I use Amsoil
    By  Mike,  a  Verified Buyer  from  OH  on  February 24, 2021

    Describe the issue

    I have a fleet of 10 vehicles and growing. I use E-350's and transits. Each vehicle puts on around 2 to 300 miles per day. The amsoil keeps the engines running quiet and I don't have to change the oil every month. I have one van with 430,000 miles and you can't hear it run. Love the product and highly recommend it.
    Bottom Line
    Yes, I would recommend this to a friend.

    Nice long lasting oil
    By  SERGEI,  a  Verified Buyer  from  MONTREAL-NORD  on  February 23, 2021

    Describe the issue

    This synthetic oil can last up to 40000 km!!! I've bought also oil filter, which is good up to 32000 km and works with synthetic oil. I'm going to use the oil to 30K km. The oil is not cheap but if take in account less oil changes, it looks like I will save a lot of money! Nice job! Keep it!
    Bottom Line
    Yes, I would recommend this to a friend.
