And when you think about it, visualize 3 quarts of Methanol/Nitro mix, and a full Quart of oil to make a gallon. I have always thought that that much oil was ridiculous. NO internal combustion would even run with a mix like that, (oil typically does not burn)...
I guess you've never tried it then because that's my standard running-in brew
and for a Fox 35 (for instance) the
manufacturer recommends and makes a fuel with 29% oil.
The point I'm trying to make is that he has several engines that are at least 40 years old and they definitely need the extra oil. This isn't guesswork either. From personal experience, I was running an engine with a cast iron piston one day and luckily I was checking the head temp. When I saw it climbing past 300F I knew something was wrong. Duh, I'd accidentally used some 20% all castor fuel so I swapped to my 25% all castor and the head temps dropped to 245F.
