Customer Ratings & Reviews

I love your products I use the 20w50 in my Harley for the transmission and primary pulse the engine it works great where ever it is placed. The bike seems to run a little cooler than with other oil

Nothing but the best for my baby's!

Great price, very convenient having it delivered right to my door for free!

Use this in a couple Harley's when doing the oil changes. First off there was a noticeable change in engine tone. Engine runs smooth. Also put it in the primary and no problems. An interesting thing found is how clear the oils is still after 3k on one and 5k on the other. The "manufacturer" brand oils seems to get darker well before that. I also want to point out that even after long long rides to and from the oil level hasn't even dropped! No one drop still at full. Been riding around with a extra qt for nothing. Will continue to use from now on. So far very please with this oil. Would recommend.

I use this product in 2003 Dyna Lowrider exclusively. Since the switch from the factory synthetic, I have noted less upper valve train noise and smoother and quieter shifts. This oil does everything I need it to do for my bike, and I have switched all of my engines and machinery around the house to Amsoil products as well.

The best oil I have ever used in my numerous Harley Davidsons I have taken a number of long haul trips from desert heat to the Rockies doesn't break down like conventional oils do I only use Amzoil in all my vehicles

Best oil in the world. The only thing I trust in my motors

I use this product in my 2004 Heritage Classic with 67000 miles. The temperature always stays at about 200 degrees, well below the operating temp of 230 degrees.

Are use this in my motorcycle, it runs cooler and quieter. the bike has 95,000 miles on it and it's running just as good as the day I got it.

2016 HD Road King

Literally the best oil I've tried and I've stress tested this on numerous occasions. Over 2000 miles in 115+ degree heat riding for over 20 hours in a day. Best in the biz for sure

Wouldn't use anything else in my motorcycle

Use this in all my Harley Davidsons. Best engine protection hands down. Any doubts, read the white sheets

Been using this oil for 10 years, for this price and quality HD can't do beat your product.

Easy to order fast and reasonable shipping A fantastic product that I've been using for the past 13 years in my Harley

It's the only motor oil I put in my Harley

My Harley Road King loves that stuff. By far the best motorcycle V-Twin lubricant period.
