SO gas is some what like glow then....sort of
I hope its not smoking like a nitro!!!!
In my .30 size helicopter I noticed oil content and nitro content change in nitro fuel from vendor to vendor due to their secret blends affecting tuning per brand. Dirty old pump gas is only gonna have so much octane regulated by local government. And the oil fortunately is up to you not very brand specific I have been using wallyworld briggs and stratton 8oz for $3.50 makes qty: 2 32:1 gallons and usually pull my plug and inspect and clean after a couple of days of flying 5-10 flights.
I would suggest not burning any more oil than 32:1 I made a mistake and trusted the upside down label on the bottle and mixed my first gallon at 24:1 left me with a dirtier plug and plane. Second gallon I am still on mixed at 32:1 is much better. I am considering moving up a bit somewhere between 32 and 40:1 my engine with recommended prop should turn at 4900rpm I am at 4400. but with it that close I may just leave it alone dont want to ruin a good thing.
