Should have said carbon based lubricant midnights will do that to ya LOL


I wondered the same thing when I contacted Central Hobbies and YS Performance and was told it gummed up and effected the silicon parts in the YS regulator. Since they are the sales/repair depot and have been at it forever I figure they have an idea what they are talking about. The team from Japan had a factory mechanic and he stated the same thing. Caster Synthetic blend was not good for the parts in the regulator.

Yes and those engines that run large ratios of nitromethane are purpose built to do so. Standard built engines, which our model engines are, run best with a methanol/nitro mix. With no mechanical overdrive to pack more air/oxygen into the cylinder a saturation point is reached and no amount of extra fuel/nitro will make more hp. Even the supercharged drag racers end up pumping raw fuel out the exhaust that is what you see as flames coming out the headers. Unburnt fuel. Our little compression timed engines have no timing adjustments, cams and cam timing is fixed. I doubt there is much advantage if any after 30 to 40% nitro. My opinion only.
