2016 street glide with tire shredder kit in the motor. Amsoil ran 15 degrees cooler the royal purple. Have a ultra oil cooler with fans and oil filter that's reusable and supposedly lowers temperature by 5 degrees. Save your money and get the oil bud. No fan draw and it's hidden. I put the oil bud on and AMSOIL ran 15 degrees cooler than royal purple.

Best on the market

Noticeable reduction in oil temp.

I use this on both of our Harley's. I really like the combo kit with filter too. Primary oil and transmission fluid are great too.

Use this oil in my ultra limited, it runs quieter and cooler.

I use 20-50 motorcycle oil in my Y2K Heritage engine. When I changed from petroleum based engine oil to Amsoil I had to slow down the idle speed. I believe Amsoil does a superior job lubricating the engine. I ride year round in temps from 32 degrees F to 102 degrees F. I don't believe engine oil should be used in primary chain case or transmission. Engines, transmissions, and primary chain case all have different lubrication requirements. Select the right lubrication for the application.

I use amsoil in my Harleys to protect the engines and drivetrains. As a benefit the engines run a lot cooler.

Amsoil provides Full protection for those hot days while riding the HD air cooled twin.

I use Amsoil in EVERYTHING!

I changed the engine oil on my Harley an the engine runs 20 to 40 degrees cooler than with the stock Harley

I am supposed to use 20-40 but I find the 20-50 makes a big diff in how the bike sounds and shifts. Been using Amsoil for years. Nothing else will do.

I regularly run AMSOIL 20w50 and sae60 in my Harley's. I also run an oil pressure gauge as well as an oil temperature gauge and AMSOIL is the most consistent I've ive come across.

Every time I use anything Amsoil I notice an improvement in motor function in every way.. truck, bike, boat chainsaw; if you know your motor you'll know the difference Amsoil makes.. You CAN feel it!!!

I only run Ams oil in my bike.

I've ran this oil in 2 identically set up Harley Davidson Twin Cam engines. First one Amsoil was added after my factory warranty was up at 40,000 miles. By the time it had 75,000 on it,it was using a quart every 2500 miles. The other engine has had Amsoil 20w 50 in it since new. It currently has 128,000 miles on it and is now using 1 quart every 5,000 miles,plus the heads have never been removed! I truly believe that it is superior to everything on the market.

Change over from HD oil, better quality and price. Got about 2000 miles oil still looks new.

Bike shifts better. Oil stays clean longer. No problems at all. Good stuff

I wouldn't use anything else in my Chieftain. Engine runs cooler and quieter.

Does the job with extended mileage.

I remember the days of sending samples in to determine when to change your oil. As a young man I did not understand why. That was in the 80's. Now the ease and reliability comes to your door step after years of testing and verifying performance. I have convert all vehicles from 59 Chevy to 2013 Roadglide without an issue. Thank You.
