I have a 2013 Harley Davidson ultra limited that I have owned since it was new. I switched to Amsoil after my second oil change. I Use three different fluids in my bike , transmission, primary fluid and oil in each of the different areas. I have had no failures and the bike runs great.

Makes The Bike Shift Very Well, Great Stuff....

Only a suggestion. Add an o-ring to the kit.

Excellent product

can't really say my transmission shifts any better but it looks as good coming out as it did going in. very little to no fuzz on the magnet. it also all but stopped a seeping shift shaft seal. softail deluxe with 60,000 on the clock.

I have been using Amsoil products for years, I have a 2005 Harley Electra Glide with over 236000 miles on the clock and have used Amsoil exclusively without issue. Best Oil on Market Today.

Beats Syn3 all day

Once I switch to this oil, it quieted the transmission down and made finding neutral easier.

Completely stopped the transmission clunking in my 2017 HD tri glide ultra.

It stays clean

I was running Synthetic 3, but after a year of research and reading reviews about my brothers/sisters saying that their bikes were running cooler & having smoother shifting, I have decided to switch. The season has not really started for me yet because good ole mother nature is being a *****, but i have had it out a few times and to be honest I can actually tell a difference. This is the oil that will remain in my bikes for the duration of my lifetime. Thank you AMSOIL for creating such a robust product. Highly recommend AMSOIL for your Harley. PS-My Personal Opinion is that my 30K dollar bike deserves to have the best of the best. Apr 7 2022

Amsoil always. I never use anything else. Great Product

Keeps trans cooler and shifts great

I have only put AMSOL in my bikes. My Fatboy is at 25,000 miles now leaks. only Preventative Maintenance.

The transmission has never been this quite. It shifts way smoother then ever before with Harley Davidson oil. This is definitely an awesome product.

First time trying Amsoil. Had Mobil 1 in the tranny. It does seem to shift a little better and neutral seems a little easier to find consistently. I cannot tell any difference in the clunk when shifting into first. Next, I plan to try Amsoil in the primary case.

AMSOIL transmission fluid is a great addition to the already awesome lineup. I will use nothing but AMSOIL products in my vehicles. AMSOIL transmission fluid takes the noise out of my transmission, smooth shifting and give me the confidence to go the extra Miles.

Top shelf protection for your transmission in any temperature. I change it once a year or 10,000 miles, it looks as good as it does the day you pour it in. I have never had a oil related issue with any of the Amsoil products.
