This kit, like all the AmsOil products I use, is of the highest quality. I use nothing but AmsOil lubricants in my Harley’s, Mercury outboard, ATV and UTV.
Bottom Line
Yes, I would recommend this to a friend.

BEST Oil for motorcycles that call for 20W-40 !!!!!
By 
BWANADAVE,

I ride a Yamaha VMax and the manual calls for 20W-40 oil. There are plenty of geniuses on the internet that will tell you “Just use 15W-40”. They think they know more about the oil than the engineers who designed the engine. What’s the cheapest thing you can do to prolong an engine? Change the oil with high quality oil !!! AMSOIL Is not the cheapest oil you can buy, but in my experience, it is the best !!!
I changed the oil in my 2025 Harley Davidson Street. The first thing I noticed the bike diffently ran quieter on the first start up. Since that time I have ridden about 2000 miles . I very happy with the oil and will continue to use in the future.
Bottom Line
Yes, I would recommend this to a friend.
