    #1 Oil!
    By  Billy,  a  Verified Buyer  from  Virginia  on  April 13, 2021

    Describe the issue

    Tried this in my 2018 RAM 1500 with a 5.7 because of the oiling problem with the cam. It has extra zinc and phosphorus which helps with wear and tear. With the first start I noticed immediately the engine run much quieter and smoother! Oil pressure was a few pounds higher as well!! I've only had it in my truck for around 1000 miles and am planning on sending an oil sample to see about the longevity but I'm betting this oil will be hard to wear out! Thanks Amsoil!
    Bottom Line
    Yes, I would recommend this to a friend.
