The lack of needle roller bearings at the top of the conrod have no bearing
on the amount of oil. The general construction of the engine (ABC) requires the extra oil when compared to a ringed engine. Our 15 & 20cc engines both use a sleeve bearing at the top of the conrod but because they are ringed engines they easily run at a 32:1 ratio after break-in.
