I was using Honda 5w30 in winter and honda 10w40 in summer, but I got
pull to try AmsOil 0w40, I have done my oil change recently, and plow, and ride trails with it, I do not like it at all!!!
Seems like it is too loose, or thin, it takes time for the gears to change and the sounds coming out of the trans and engine do not sounds really good!!
I think it is because the viscosity is too much!
I will tell you that when starting the engine, it is alot better than Honda oil tough.
I will change mine back to Honda 5W30 tomorrow!!
Looks like the clutch is slippering with AmsOil 0w40.
My 2 cents.
