I think you could be confident if someone contacted the local fuel distributor and did a deal for x number of fills over the event = x no of litres of ULP, and provided credit card dispensing to the wing. 1 Link to comment Share on other sites More sharing options...

There are a lot of politics both ways ie the CASA delays to group G and then quickly bringing out basic 5 med makes you wonder. Its do-able but there are always Casa rumours. Would require hiring extra staff on a constrainted budget. Annual Casa rego/license fees rumour also floating around but unable to locate source. 1 Link to comment Share on other sites More sharing options...

skippydiesel Posted April 8 Author Share Posted April 8 I am definitely "overly fussy". While I have used AvGas, about 2 times over 15 years, I will make every reasonable effort to avoid it. On "away trips" I carry two x 20L collapsible bladders/jerry cans, so that I can get a lift/taxi/walk to the nearest appropriate servo for fuel. I dont think its unreasonable to expect that a Fly-In, that is principally aimed at small (RAA) level aircraft, many of which will use ULP, would organise to have this fuel available. 1 1 Link to comment Share on other sites More sharing options...

The rumour I heard came from casa but it is still a rumour. If anything does come of it how will it looks anyway. Maybe casa will keep raaus but get involved with running it.

I run my xair on avgas because I know it can sit for a while without going off. It's a jab motor so it can run either. The $2.80 a liter makes my eyes water though. Lucky it only holds 50 lt. 1 1 Link to comment Share on other sites More sharing options...

facthunter Posted April 9 Share Posted April 9 Rotaxs's don't like 100 LL They run the heads too cool for the lead to flow but I reckon ONE part tank full won't damage it. Incidentally, Lead doesn't help GUIDES unless it was a real old thing that runs really hot made last in the 20's. Nev 1 Link to comment Share on other sites More sharing options...

Nev i never knew that. i only use it so i don't have fuel going stale and it has been run on it since new . i was talking to a bloke with an avro biplane , he said it doesn't like avgas because the lead builds up in the bottom cylinders.

Maybe phone floods for info, have heard of mixing decalin (very small ratio) so the lead does not build up for Rotax 582 engines. Best check it further. The 4 strokes are ok according to Rotax under 30% usage. A mate who does oil analysis tells me it takes 2 oil changes to get the lead reading zero in the samples.

facthunter Posted April 9 Share Posted April 9 (edited) The LOWER spark plugs will often show the effects of TEL build up first . with 4 stroke FLAT type motors. If in a hurry the mechanic checks them FIRST. There's also ground running procedures where you can clear the fouled plugs by leaning the mixture at a relatively low power setting say1800 rpm for a Lycoming. Do it into wind if possible More likely with planes that do a lot of taxiing' with a rich mixture. Yes I reckon Lead would Pug up 2 stroke rings. The oils are matched/ formulated to running piston temps though and that's going to vary. Build up on the Crown can be dust, carbon Lead and almost any sort of thing including oil additives and metal wear particles. Some friction modifiers short out spark plugs More likely where the motor is one that uses a lot of oil..

skippydiesel Posted April 9 Author Share Posted April 9 Thanks Blue, I am aware of Decalin - very popular in the USA. I am on my second Rotax 912 ULS - except for the 1-2 times/15 years, I topped up (shandy) with AvGas, I don't use it. There is no discernible improvement in performance (I am told there may be a high altitude benefit, but I don't fly above 10,000ft ). There is a significant cost/L penalty and if used regularly, additional service cost due to lead build up. I don't plan on using AvGas any time soon. Decalin treats a problem, that I would rather avoid in first instance. For pilots who don't fly regularilly, AvGas is much slower to "go stale" than ULP (especially 98 RON). I haven't been in this situation but would suggest draining tanks & carburettor bowl, rather than using AvGas. Thanks anyhow for the thought Link to comment Share on other sites More sharing options...

I might be wrong, I am just thinking like a business owner Mini Tankers may not service the Parkes area, but if they do you can fuel a tractor, generator, pump etc.\ The other truck is a typical local distributor for a district. The farm delivery truck usually carry about 6000 litres of fuel (4x2) or 16,000 litres 6x4 and depending on the district may have one or two bulkheads to separate the fuel types including ULP. They are usually out on farm rounds every day and will call in to drop of one 20 litre drum of lubricating oil or fill one tractor. In the cropping or cotton area the configuration can be 8x4 with a 4 axle dog trailer. The 4x2 or 6x4 would be making a stop at the airfield for a short time, just as he would for a tractor. 2 Link to comment Share on other sites More sharing options...

facthunter Posted April 9 Share Posted April 9 I've observed instances of uneven compressions with the 912s after using Leaded fuel and in every case it came back Ok after about 2 tanks. of Mogas. Don't bother with Leak down tests It can be felt when burping the oil back IF you are used to the normal/right feel. If you are as fussy as, you take the heads off and reseat the valves but NOT pulling engines apart UNLESS you must is best.. This is not new information. Nothing has changed in the last 20+ years. IF it further deteriorates after returning to mogas. get onto it. Rotax 4 stroke Heads are NOT a problematic item generally. Judgements have to be made in these things on a balance of informed possibilities. On other occasions I've said don't ignore a new vibration feel of engine beat etc find out what it is and I've said engines don't fix themselves. WE are changing a causal factor by eliminating it and having a good chance of success. Nev 1 Link to comment Share on other sites More sharing options...
skippydiesel Posted April 9 Author Share Posted April 9 Have contacted the fuel company that will be servicing the Fly-In. Person I spoke to, didn't know that many small aircraft use ULP and has no plans to make it available for the event. 1 Link to comment Share on other sites More sharing options...
