Hi Guys,
Wondering if anyone can help me out in the fuel department.??
The long lived debate between avgas users and hi octane unleaded, in outboard racing has always interested me.
My understanding is that tetraethyl lead was introduced to "fuel" years ago to raise octane levels, and for exhaust valve seat protection in 4 strokes
Obviously emission laws have faded leaded fuel out in Genral automotive vehicles, but aviation industry still use leaded fuel (avgas) for its exhaust valve protection and its anti knock properties.
My question is, is there any benefit in "avgas" other than its anti-knock properties required in high perf. 2 stroke, or any high compression engine?
Cheers Guys,
