Great oil for summer and winter

Transmission shifts much smoother and a lot less noise compared to using Honda oil.

Great product and seems to be a good replacement for the Honda pioneer 700

Good over all oil

Best oil ive ever used.

Great product, use in all my bikes and quads

I've been running this for a couple years. No issues at all. Lasts well and great for full throttle riding

Best oil for wet clutched atv's. My arctic cat loves this stuff.

Amsoil synthetic oil offers great protection for your 4 Stroke! Maintains viscosity in all riding conditions!

Tutto perfetto grazie

I have run this in both my 1987 Yamaha Big Bear as well as my 2004 Can Am and run like a watch. Whether riding tough terrain or working hard, the oil stands up and keeps the bikes running well.

I haven’t used it yet. Will do so this fall before hunting season begins. This was recommended by several friends that use this product and have had very good results.

Great product fast shipping! Thanks Amsoil!!

great stuff

I was using 5W-30 on my 2009 Yamaha Grizzly 550. I winter time it was hard to start but now with the 0W-40 it's start almost like we are in summer. The only thing is I don't know how that thin oil will hold during summer time. This is where I get scare. My owner manual call for 10W-30 for summer operation.

Very good oil and fast shipping Thanks A+++++++

We have used this oil in our 2004 Bombardier 4 wheeler since we bought it new. It has over 3000 miles on it and still runs great.

As always top notch products.
