    WON'T BE USING ANYHTING ELSE
    By  JOHNNY,  a  Verified Buyer  from  Daphne, AL 36526  on  December 02, 2024
    Been using Amsoil products for years, I have it in everything I own from the zero turn mower all the way up to our restored 1975 Ford F100. I bought a 2007 Chevy 1500 Z71, new in '07, and at 220k miles I had the cam updated to a stage 2 with AFM delete package. When we tore the engine down there was ZERO "gunk" build up. I ran 5W-20 in that truck from the first oil change, changing every 7k miles and other than your normal maintenance stuff never had a major problem with the truck. 16 years later the truck has 280k miles on it and it's still going strong.
    Bottom Line
    Yes, I would recommend this to a friend.

    It's the BEST!!!
    By  BRAD,  a  Verified Buyer  from  Northern Michigan  on  November 25, 2024
    I have used this product for several years in my 3 vehicles (all pickups or SUV's), and all of them over 20 years old. They all have had zero engine issues related to lubrication and they all have over 150K miles on them. I can highly recommend this product for any vehicles that have high mileage and follow the manufacturer's oil change/mileage requirements.
    Bottom Line
    Yes, I would recommend this to a friend.
