Q: How much is 98 Octane?

[Keeper]

Avgas is specially tested the whole way from the refinery to when it gets put in Aircraft to ensure it has no water content unlike normal fuel, your engine can cope with a small amount of water, but at high altitudes it freezes the lines in Aircraft and causes crashes,

Lead - > Billions of the stuff in Race fuel and AvGas - > don't honestlly know what this could do to your cat, but too much (i suppose if you ran your engine all day on leaded) might cause a lead build up on the valve stems off the top of my head.

my duc runs better on 91 than 98... the cbr was the otherway around

fuel should have lead... lead was good... stoppped them putting all sortz of other shit in there...

btw... duc sat for a coupla weeks with bp fuel and then refused to start without fouling plugs.... used mobil fuel and it started straight away after me being in Oz for a week.... and starts everytime now even on the coldest mornings....

DONT USE STALE FUEL..... and stay away from BP
