Customer Ratings & Reviews

I have been running Amsoil V-Twin 20W-50 in my Harleys for the last 20 years. Never had an issue and gives me peace of mind having it in the bike, current bike is at 76K miles. I still change fluids every 5K even though it supports longer intervals. I tend to make a lot of short trips so I change it more often.

I run this in all my Harley Davidson's. It keeps the motors cooler and smoother. I am assured that it will keep everything lubricated and surpass any bearing test.

Love the product. I ordered once and missed out on the free hat offer. Maybe next time

Got 180000 km on my twin cam 2008 without any motor work has to work for my 22 heritage.

Had this order shipped to a Brother in my MC Club. No problem using an address other than my home address. Thank you Amsoil

Been using this oil for over 2 years engine run smooth and quiet

Awesome oil and lower head temperature would highly recommend it

Although the oil is good it did not include any o-rings to go on plugs

Parfait pour mon bike

This is the best on the market for my Harley Trike. I wouldn’t buy anything else

I'm tired of paying the high price for oil through HD. I searched and found several BLOGS in regard to AMSOIL vs HD OIL (20W-50) It's much cheaper than the HD oil and the research shows that AMSOIL is equally as good as the HD oil IF NOT better...!!!! I want the best bang for my buck....so I tired the AMSOIL 20W-50 on a trip to STURGIS.. I thought the AMSOIL performed well. Avg temp was around 88-93... My bike burned "0" oil in 1750 miles. Pretty much sold me on what I will be using from now on. Only issue was when riding the "Iron Mountain" and "Needles".... clutch got a bit sloppy..... I will have a local dealership look at that.

A nice combo. To get a oil change DONE and Done. Add in some Transmission and Primary Fluids and you have a yee old three hole change!! Good to go!!

First off I wish I could submit pics with this review. I change my oil all 3 holes once a year and its well over 10k miles. Everytime I change my oil it still comes out clear. Engine runs cooler and saves fuel.

This is down right the best oil to use in all your gas powered items I recommend using this product you will not be disappointed

Meilleur pour mon bike

My new Harley will have all Amsoil products from here on out.

Good stuff!

The special Primary fluid is worth the extra couple of dollars. Bikers to shift more smoothly and quieter. I will not go back to the same oil in all three holes.

I tried multiple oils but Amsoil helps my bike run cooler and I definitely noticed a difference in the summer heat.

Been using this oil for years on my bikes and friends of mine with never any problems will continue to use this oil also use amsoil in both my trucks thanks for a great oil
