My new Tanaka weed whip instruction manual calls for a gas oil mixture of between 25:1 and 50:1. That seems kind of vague to me. My Echo leaf blower calls for 40:1 and my Poulan chainsaw calls for 50:1. Running my Poulan on a 40:1 seems to work fine, and I am planning on running the Tanaka with a mix of 40:1. Is it super critical to stick with the recommended mix for each piece of equipment ?
