with phase separation during storage water and water/ethanol
sink to the bottom of a storage or your tank then cause stalling
when drawn into injectors/combustion chambers..
best way to avoid this pre-storage is use pure petrol..
also especially with ethanol blends, mix the blend
by moving it around in the tank.. taking it for a ride
now and then should have at least some mixing effects..
[start/stop, leaning should slosh it around in there]
basically, our 10.5:1 cr combustion chambers do not need,,
slow burning [ie, high octane rated] petrol..
our cr engines are designed for fast burning fuel..
slow burning - high octane fuel resists pre-ignition,
thus engine damage, in high cr performance engines,,
resulting in a general [wrong] association between
high octane and performance - in low cr engines..
here [aust] 95 and 98ron 'premium' petrol is ethanol free..
ethanol is added to the 91ron [about 87pon], thus motorists
are forced to pay for 'premium' to avoid ethanol.. a ripoff..
some outlets [here] do sell all fuels free of ethanol..
i have only ever used 91 pure petrol in my cbr250r
and two cbr300r's, all of which have started
first touch of the button, incl cold mornings..
apparently in usa there is 'recreational' 'rec-90'
for marine engine and small engines..
also for some aircraft engines..
[to avoid 'damage to their engines']
if you have pre-ignition for some reason
perhaps try 95/8ron as diagnostic and
to avoid serious engine damage..
otherwise use fast burning 91ron [87pon]..
- slow burning high octane fuel will not
increase your 10.5:1 engine performance -
