    Octaine Boost Review
    By  Larry,  a  Verified Buyer  from  FL  on  February 09, 2022
    Failed to verify captcha
    I use this in my 33 ford street rod with a high compression V8. Since the car sits a lot over winter I use non-ethanol fuel in my local area. Most of this product is around 90 octane and pings if a octane booster is not added. The Amsoil product works great to solve that problem.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Glass Cleaner Ever
    By  Whitesheep,  a  Verified Buyer  from  Phoenix AZ  on  October 19, 2021
    Failed to verify captcha
    We don't have many bugs other than their poop here in AZ, but we get nasty rain dirt and hard water stains from sprinklers. This stuff is a little more time consuming to use, but it works great. Try a can and you will not go back to the other window stuff.
    Bottom Line
    Yes, I would recommend this to a friend.
