[QUOTE="Ansimp, post: 122068, member: 2637"] Pinging is pre detonation of the fuel ( firing without spark prior to the ignition) similar to how a diesel works ( just compression and combustion chamber temperature), as Randy said slowing down the burn rate alleviates the problem. By using ATF this should have a similar effect, I can't confirm this as I haven't experimented with the lower octane fuel. Here in Oz I use a 95 octane rather than our regular unleaded of 91 and definitely not our 91 ethanol blend. I only use ATF about every 3rd tank as I don't like the smoke on start up ( I suppose I could try using less) and I haven't found an old 200ml container to carry on board the Rats Nest. We have a 98 octane available here but unless you are fuel injected it does nothing to improve performance or economy. In the States I was always using 89 or better as on our trip my brother and I shared the one pump and we always used the highest octane for his 2012 Road King. [/QUOTE]
