The Klotz Uplon® Fule Lube is originally a fuel additive for 4-stroke full-scale applications. But for R/C it's a really good after-run oil that blends with methanol alcohol, ethanol, nitromethane and gasoline. That means it does not repell the fuel residue in your R/C engine and it protects the engine very good. It can also be used as an very good assembly lube when you have changed bearings or a new piston/liner/rod etc in your engine.

If used as an R/C after-run oil:

• When you are done for the day - empty your fuel tank
• Start up the engine on low revs with the remaning fuel that is still in the fuel filter and fuel lines
• Let the engine idle until it runs out of fuel
• Start the engine again, and again, and again until all fuel in the engine is burned up
• Remove the glow plug and squirt a few drops of Uplon® into the cylinder
• Open up the carb and squirt a few drop of Uplon® into the carb throat
• Turn the engine over a few times to distribute the Uplon® inside the engine
• Attach the glow plug and put on a new air-filter on the engine
