I assumed the water was coming from the...
Yes, the oil does get dilluted with the fuel over time, more if running richer. Since you use more fuel running alcohol, it gets dilluted quicker, so you need to change the oil more frequent using alcohol.
Not to be rude, but an internal combustion engine also converts heat energy from combustion into mechanical energy. Your reply tells me you don't have any formal training in the operation of an internal combustion engine.Your also confusing heat with temperature, you mention an acetylene...
To get back on track and answer the OP question. A turbo is a mechanical device that converts heat energy into mechanical energy, so the more heat you apply to the turbine wheel the more pressure it can produce at the compressor.
When you rev the engine without a load, there's not enough heat...
You should use 91 minimum, or 93 if available to play it safe. Using low octane fuel, will cause the timing to be pulled, making you use more fuel, which defeates the purpose of using cheaper fuel.The lower octane fuel also causes the engine to knock sooner, and over time it adds up to...
