I guess I'm still stuck in the past.
I BELIEVE in using a non-synthetic oil for break in. I'm talking real oil made from real dead dinosaurs.
I've run just under 5 gallons through my G-62 on this combo and not a bit of carbon on the piston. It's still shiny as new. I might switch to a synthetic after 10 gallons--but thats a bit off in the future. I'll decide later. If I do switch to a synthetic--it'll be a 50:1 mix.
There's just something in my brain that says oil is good for cooling. More is better--up to a point. If your not fouling plugs and your not building up a bunch of carbon on the piston then why screw with it and try to run an engine at 100:1?
I'm not saying that anyone is wrong or stupid for running 100:1 or even 80:1. Not at all.
I just know that oil is good for cooling and it won't hurt a darn thing to run just about ANY engine at 40:1 or 50:1. As long as your not fouling plugs or building up carbon--oil is a good thing. It carries away heat and lubes the rings--bearings--reeds--seals.
But- I'm probably wrong as all get out.
