Amsoil is the best. We all know that. However, I'm disappointed that you guys don't know a Harley M8 takes more than 1 quart in the primary. On another note, I didn't get my free hat that I put in the code for.

With temperature swings going from one extreme to the other, in a single day, the best protection possible is necessary for my V- twins. Amzoil provides just that kind of protection!

Amsoil makes it really easy, tell them your vehicle, they send the exact oil change kit you need. I have bought four of them in the past two months, everything delivered perfect and fast. Plus, if you become a member, you get really great savings. Love this company!

It’s currently the best oil on the market for my bikes

Using 20-50 for the Hot temp when I ride my Victory KP in the Summer.

This is the best oil for protect your V-Twin Harley

Great product

I bought this 07 Fatboy used with 7000 miles on it. I changed the oil with Amsoil and it runs so much better, I also changed the primary and transmission oil at the same time.

Great oil. Great deal and great service. Only oil I put in my Harley’s. I use amsoil synthetic 15w40 in my sport bikes.

I orders the kit and one qt only had about 1oz in it. I’ve always used amsoil and I like it but I’ll check the bottles when I get them from now on

I’ve always used the AMSOIL in my Harley and it has worked well. My on line order was supposed to come with the transmission fluid and the primary oil but I was sent just the 20/50 oil that is suitable for all three. I’ve always used the three different oils but I understand that the formula has been designed to work for all three holes. I decided to try the one oil for all three and will see how it performs on our annual bike trip to Arizona in April.

Keeps my Twin cam 88 cool and quiet in the Florida heat. Best oil i have used.

EXCELLENT/FAST SERVICE AS USUAL , THANKS

Parfait pour mon Harley

This oil for Indian 111 thunder stroke engines is better than oem Polaris oil. Big noticeable difference in the clutch operation. No slippage or high heat chatter. Been using it for 2 yrs...highly recommend.

Easy to find what I was looking for and shipped fast

Product makes my bike run great and with no issues

This by far is the best product available! Noticed a huge difference in temperature, of my air cooled vtwin, as well as the primary smoother shifting wow ! Very much recommend.

As always this is a great service, thanks

Using it on my 2021 Harley Davidson Low Rider S I’ve had since new. 12,000 miles only using this oil and no issues. Oil & filter changed every 4,000 miles. Not sure how much value in this review but I am happy with it as my bikes oil of choice.
