    20w50
    By  RICK,  a  Verified Buyer  from  Saskatchewan Canada  on  May 22, 2022

    I switched to AMS oil 20w50 in my 2015 Harley Davidson FLHR because both types of OEM Oils, synthetic and petroleum based, wouldn’t hold up. After 3000-4000km of hiway use I’d be down 1/2-3/4 of a litre. Bike had 25000km on it at the time. Proper break in. Leak down test proved engine was fine ect. The OEM oil just evaporated. I’ve used AMS Oil products on/off since 1979 so I gave it a try in my HD with immediate satisfaction. I change oil between 8000-10000km depending on my season or trips and add nothing between changes. Maybe down 1-2 cups of oil. It stands up. I have 140,000km on now(spring of 2022). I’ve have some friends experience the same with their Harleys. AMS Oil 10w40 is going in my Suzuki VStrom prior to my 12000km round trip to northern Alaska and back. Good stuff.
    Bottom Line
    Yes, I would recommend this to a friend.

    I had a engine Inspection done on my 2005 Harley Davidson Ultra Classic at sixty thousand miles. The mechanic enquired on what type of oil I used after the inspection. I told him I used the Amsoil 20w 50 for v twins. He said it would probably pay for me to stay with this product that my engine looked new.
    Bottom Line
    Yes, I would recommend this to a friend.

    My go to oil
    By  ALBERT,  a  Verified Buyer  from  NJ  on  May 16, 2022
    Failed to verify captcha
    I’ve been using Amsoil for my 2016 Indian Chieftain. This oil maintains its viscosity as witnessed when my old oil is being changed out. Also, I like that this is a synthetic oil vs. the semi-synthetic blend from the OEM. Keep up the high quality Amsoil!
    Bottom Line
    Yes, I would recommend this to a friend.

    Dealership Oil Kit - vs - Amsoil
    By  DAN,  a  Verified Buyer  from  TX  on  May 16, 2022
    Failed to verify captcha
    The dealership for the Indian Chief 2022, offers an oil change kit with 5.5 quarts and filter for the same price as Amsoil 6 quarts of full Syntectic. Dealership oil is a Synthetic blend - plus the bike uses 6 quarts - you end up buying an extra quart just to get the level right. Some people call Dealership - Stealership. I'm glad I took care of my 500-mile break-in - with Amsoil full Syntectic
    Bottom Line
    Yes, I would recommend this to a friend.
