I got banned for advocating 25:1 using a barrage of research to prove that higher oil/fuel ratios reduce localised hot spots from excessive bore distortion as well as reducing piston ring wear from the previously said condition, which consequently increases engine power by reducing blow-by, not to mention an improved hydrodynamic gas pressure barrier; despite the fact that with all of the supporting evidence the moderator insisted Optimax used at 100:1 was "good" for your engine and would not have "any" negative effect on engine life or engine power.
Calling the moderator a small minded peanut for not accepting the research didn't help.
