Using 98 RON, in engines that can not benefit from the higher octane rating, will do no damage other than to your finaces. Expensive 98 RON is for high compression petrol engines. Cheaper 91 RON at the other end of the scale is for (relativly) low compression engines. The practical effects of using a low RON fuel, in a high compression engines ( usually sport cars/Rotax 100 hp & up) is the potential for destructive "knock". For optimum cost/effect - use the fuel grade recommended by the engine maker😈

No offence Onetrack but that pro electric truck screed, sound very much like aspirational market speak eg "Aerodynamic drag coefficient of 0.16 - lower than most sports cars - reduces energy use to 1.1 kilowatt-hours per kilometer at highway speed under full 37-ton load." There is no way on earth a conventional trailer (as shown), even drawn by a aerodynamically sculptured prim-mover can come close to a half descent sports car's drag performance - defies everything I understand (?) about aerodynamics. Then there is all that guff about matching driver rest stops - in the real world even electric trucks will have varying energy consumptions due to terrain/ wind/traffic conditions, which will mean, as now, varying trip times/stops. Yes, this is the dawn of electric energy, almost everything, but lets not get ahead of reality.😈

At the time of my tail wheel training I was a lapsed PPL. It turned out, to my surprise, that by doing the training, I also obtained my GA BFR ie became a current PPL. It may be a GA licence (even lapsed) may be the key - something for you to investigate with RAA😈

Did my tail wheel in a VH registerde Citabria with GA instructor - not a problem😈

You have to be joking 😈

GA tail wheel training would seem to be more common - try the GA schools. Likly cost more. The endorsement still counts.😈

Can it be true that there are no recreational/private pilots in the Rocky area????😈

You jest. There is no MoGas in AU. Its just a marketing/sales gimmick, that can only confuse those looking for a suitable ULP fuel. Rotax recomend 98 RON (best knock resistance) or if you must, 95 RON, for its 100 hp & up. For the 80 hp you can go as low as 91 RON . Note: MoGas is not mentioned. I suspect that even the LYCon's, that can use ULP, will be looking for 98 RON. Its the the ULP of your choice OR AvGas (including lead) 😈

Petrol "How much fuel will we have?" in the months to come. My gut feeling, petrol will still be available however the price may be eye watering (I remeber petrol at 25c/L). Diesel is another matter - may be rationed, to non essential activities (domestic use) to preserve it for industry & essential services. It seems to me that the Australian public, still do not comprehend the importance of diesel to every aspect of our society (including its influence on the price of petrol). The Gov encourages this lack of awareness, by lowering the tax on all fuel. True they have removed the heavy vehicle Road User Charge (RUC), but what good does this do for the fishing /farming/etc non road industries?? The proper response would have been to remove entirely the various taxes/levies on diesel, for the duration of the emergency. This would have assisted all diesel dependent industries & services, (inc the cost pf petrol) and had a moderating influence on the rising cost of living. Personally I am reducing my flying hours - not so much spontaneous levitating, in favour of a few planned trips, with know fuel availabity (if required)😈

Maaaate what country do you hail from?????? MoGas is a USA marketing constriction of the term Motor Gasoline - Gasoline (Gas) being the US popular name for petroleum (petrol). In Australia we use the more acurate descriptor - Unleaded Petroleum (ULP). Petroleum often shortened to petrol or ULP. ULP commonly comes in 98, 95, 91 RON & E10 (Ethanol 10% blend). "MoGas Regional" is also the name of a fuel distribution company. In all cases a cringeworthy attempt to define their offering as something special, (marketing hype) by adopting an overseas term -sad!. A ULP supply at Camden airfield, will struggle as the vast majority of aircraft at that local are powered by LyCons (likly users of AvGas ). This combined with being a tower controlled airfield means few RAA level aircraft ( often ULP users) frequent the facility. 😈

Just been looking at the jumble of control steps around Rockhampton (YBRK) - would like to correspond with a local pilot, as to best way to get to Hedlow (YHEW) when inbound from the south of YBRK??? 😈

Not sure that I agree with "Some cars won't run well on 98,..." My understanding is that its not worth (ie nothing to be gained) putting a higher RON fuel in an engine designed to run on a lower RON. I recon you could put 98 RON in your your lawn mower. It wont object , neither will it do anything better. Putting a lower RON in an engine designed for higher RON, will certainly not do the engine any good, may knock. 😈

In my (limited) experince; 98 RON is good for at least 4 weeks in the aircraft tanks (open to atmosphere) Can be refreshed to almost origional standard by adding fresh 98 RON (shandy) Why not refresh the fuel in say 4 weeks with 98 RON, fly the aircraft to 1/4-1/2 tanks - repeat every 4 weeks until normal flying start again. Or drain As much 98 RON out of tanks as possible, replace with AvGas to full tank, go flying for an hour or so, park plane. Depending on how long you anticipate not flying this aircraft I would: Drain the tanks Drain the fuel lines & blow out with compressed air, if in doubt as to efficacy of drain. Remove & drain the carburettor flat bowls On the last two - I doubt that running the engine until fuel exhausted will remove all of the fuel. This then leaves small amounts in system (including float bowl) which will evaporate relativly quickly, leaving a "varnish" (gluggy mess) , which may or may not cause issues when you next fuel up & try to start the engine. Disconnect battery & put it on trickle charge. The 98 Ron in the "jerrycans" If filled to at least 75% capacity (more is better) will last at least 6 months (likly much longer), as long as container air tight. For container integrity - best to store out of direct sunlight 😈

Thruster 88 "I agree, Narromine is better." As was Temora. I am not particularly attached/attracted to any location, just apposed to any Security Controlled airfield, as I feel that the accessibility of the visiting aircraft/pilots to the, potentially aspiring aviator, public & other pilots is an essential part of a successful RAA event. Further just the potential for the long arm of the authorities, to slap a non ASIC holder, with a mighty fine, is a mood dampener in itself. 😈
