    2013 Harley Davidson Triglide oil chang
    By  JOSE E,  a  Verified Buyer  from  Houston, Texas  on  October 05, 2025
    Changed my oil using the 5 Qt + Amsoil Oil Filter. Everything went OK, actually only used 4 quarts of oil + the Filter. I typically use KN 171C oil filters but found out that the Amsoil filter is much more difficult to tighten, hand or otherwise. I am sure the Amsoil filter is good, but the installing it on a Trike was challenging.
    Bottom Line
    Yes, I would recommend this to a friend.

    2020 street glide oil chg...
    By  PETE,  a  Verified Buyer  from  NH  on  June 09, 2025
    I was disappointed this time. The "kit" came with oil, and filter, but no o-ring for the drain plug as clearly pictured and called out in the description. No biggie, just a trip to the NAPA parts store and got the job done. QC at the assembly plant for the kit must've had the day off???? It would be good if there was a "Deluxe" oil change kit that included primary fluid and an extra qt of 20-50 to do the trans.
    Bottom Line
    Yes, I would recommend this to a friend.

    V-Twin Oil Change Kit
    By  TRAVIS,  a  Verified Buyer  from  Comox, BC  on  May 15, 2025
    Nice piece of kit, except there was only one o-ring which I used for the engine oil. I would have preferred to have two more o-rings for the Primary & the Transmission. Just sayin'.

    New to Amsoil
    By  THOMAS,  a  Verified Buyer  from  Manorville NY  on  February 09, 2025
    Arrived quickly. Can’t find the “o” ring in the packaging. I ordered a bag of 12 on Amazon… I looked a few times… but I’m famous for not being able to see stuff that’s right in front of my face… it’s better that I have a little stock on hand anyhow…I’m sure it was either an oversight or I’m blind

    Quantity
    By  GEOFF,  a  Verified Buyer  on  November 17, 2024
    Amsoil quality is never a question. The kit requires an additional two more litres for a three hole oil change, on a 2017 Harley Street Glide.
    Bottom Line
    Yes, I would recommend this to a friend.

    Oil change kit
    By  BARRY,  a  Verified Buyer  from  Arizona  on  June 03, 2024
    I really like the process of purchasing the "kit", for getting the products needed. I've been using AMSOIL in a variety of vehicles for nearly three decades. My opinion is that it is the best oil on the market, but you do have to pay a bit for it.
    Bottom Line
    Yes, I would recommend this to a friend.
