star-tron is a better all the time use product
it helps with the ethanol fuel problems
as for oil in the fuel, yeah you could do it, no more than a 50-1 mix
this is common practice on new engines, but not needed on a proper engine
but just check your pump adjustment, maybe advance it a bit if you want
carry those extra plugs tho, and a wrench
spark plugs are cheaper than top ends
