My dad get's dealer price for Amsoil and just gave me a quart of Amsoil Sabre. I just ordered a Kawasaki backpack blower and also use Husqvarna 223L trimmer, and an echo handheld pb250. Should I use the same ratios for all 3 of these? If so what would be the ounces for an 80:1 mix for one gallon if that's what you'd suggest? The label only gives ounces for 5 gallon mix for 80:1.
