    Awesome product!
    By  SHANNON,  a  Verified Buyer  from  Iowa  on  March 14, 2025
    The best oil I have ran. Normal riding to track this oil seems to keep the temps good, does not foam which I found cheaper oils to do. Just over all great.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oil but priced too high
    By  DAVID,  a  Verified Buyer  from  Arizona  on  February 22, 2025
    Will probably look for an alternative oil. I change oil every 5k and I spend about $100 per oil change using Amsoil. Probably not cost effective.
    Bottom Line
    Yes, I would recommend this to a friend.

    Bmw K 1600GTL
    By  GREG,  a  Verified Buyer  from  Colorado  on  February 03, 2025
    Brought the bike to the dealer for recal work. Unfortunately, they drained my Amsoil and put in BMW synthetic. On the way home I notices clunky shifts like a Model A. Waiting for my Amsoil order to arrive for a buttery smooth transmission.

    Good Oil
    By  Stone,  a  Verified Buyer  from  CA, USA  on  January 21, 2025
    I'm not racing, doing high miles, or doing oil testing, so all I have is my subjective impression. This seems like very, very good oil.

    First Rate Motorcycle Oil
    By  KIM,  a  Verified Buyer  from  Livonia, Michigan  on  January 08, 2025
    Amsoil products are always top notch and outperform expectations. Picked up the 10W-40 for my niece's Suzuki GSX-R 600. Engine revs smooth as silk and she zero issues with shifting or clutch engagement.
    Bottom Line
    Yes, I would recommend this to a friend.

    Smooth Shifts
    By  DEAN and LINDA,  a  Verified Buyer  from  GTODEAN  on  January 01, 2025
    Changed over to this oil in a 50-year-old Honda 750. It had always been chattery when shifting into gear after winter storage with conventional motorcycle oil. Once switched to over to AMSOIL the clutch operated smoothly, and shifts were quiet and uninterrupted in flow
    Bottom Line
    Yes, I would recommend this to a friend.

    Hidden cost
    By  CALE,  a  Verified Buyer  on  November 25, 2024
    I think this is some of the best oil out there, that being said there online cost calculator is horrendous. They seem to be unable to tell you what tax is going to cost depending on your state which is minor but the real problem is they try to bill you 3 days later for " hazmat costs" if your state requires it let me repeat that 3 days later which they don't show you a list then tell the customer to go find it for themselves. Then it takes 4-5 different customer service emails about the same subject to get corrected. Very irritating for what should be a easy fix. So 5 stars on the oil 1 star on there ability to tell you what you are actually going to be billed. To be fair they did waive the hazmat cost "this 1 time" but it still doesn't look like they fixed the problem.
    Bottom Line
    Yes, I would recommend this to a friend.

    My only synthetic
    By  RANDY,  a  Verified Buyer  from  North central USA   on  November 21, 2024
    I use this oil in my 2020 Triumph T120 and 2021 BMW K1600. Both bikes shift well with good clutch feel. I do believe my 1600 runs a bit cooler on hot congested traffic days. Neither bike has a consumption issue. The transmission and engine oil are common on both bikes. Too that end I’ve never noticed any metal on the magnetic sump plugs. I also use Amsoil 80w90 in the final drive of the Beemer. After initial change I haven’t seen any shavings on my drain plug.
    Bottom Line
    Yes, I would recommend this to a friend.

    AMS Oil
    By  MARK,  a  Verified Buyer  from  Canada  on  November 19, 2024
    I ordered the oil change kit with the wix oil filter for my 2009 R6 the oil was a perfect amount but the filter does not fit. The filter threads on great but it hits the shift linkage preventing the shifter from returning to its proper location when not shifting.
    Bottom Line
    Yes, I would recommend this to a friend.

    I have been using Amsoil since 2012. I’m now using it in my 2024 Triumph bobber. After my first oil change I noticed smoother shifts and less valve train noise. I will continue to use this product in everything I own. Great oil.
