RE: Turbine Engine Oil
My understanding is acetone helps with tick over but does nothing for top end power so 3% is all that is needed to replace 5% nitro which does the same funcion
Nitro Methane helps with tick over low ed tourque and high end power
Nitro costs often 3 to 10 times the price of Acetone
Using high compression motors types can restore the power lost from low nitro or zero nitro
Then using Acetone to help tick over for these motors can be a lot cheaper than nitro solutions
However Acetone can evaporate out of the fuel easily and may require replacement
My understanding is Turbine oil is used at 2 to 3% as extra protection for the main oil type such as 15% synthethic in USA or 8% EDL as in Europe
A typical budget formula I gather is
methanol 80%
Acetone 3%
Oil synthetic 15%
Turbine oil 2 %
