    My motor was from Zoom I've had very good luck with it. They were friendly and helpful. One thing the manual and their site has a typo. It says to break in use 16:1 oil mix ok that is correct. The typo is, it says mix 6oz in 1 gallon that's like 24:1. 8oz in one gallon is 16:1

    Just goes to say the manufacturer doesn't even know how much oil to use in the engine. 16:1 is crazy too much and will do nothing but kill mosquitos and other bugs. 32:1 is where I start.

    Most of the makers of these engines say to run a 16to1 mix at break in.My Tecuseh 49er runs at 25to 1 and is smokey ,and I do not run Syunthetic oil ,I run the regular two stroke oil.

    I think 16:1 is a good start mix but just for the first gallon. These aren't what you would call precise motors. I have had no smoking problems with valvoline 2 cycle for air cooled engines even at 16:1. Outboard oil is for water cooled motors. I went 8oz for 1st gal. then 7 then 6. I'm almost out of the first quart I bought and I'll switch to synthetic next then I may go 5oz per gallon but I think 4oz (32:1) may not be enough for these motors.
