I just got a zr 440 that I need to premix in, this is the first sled I’ve needed to premix for, the guy before me said 32:1 klotz or amsoil but around me nobody sells klotz and amsoil interceptor is about $45 a gallon. Do I need to run those expensive oils or could I just run like the valvoline multi purpose 2 stroke TC-W3 which is half the price about $5 a quart? Does it matter that much? For engine life? And longevity?
