BP at Sunbury-Upon-Thames might be pretending to be Yanks, but we're taking about Australian fuels here so that's not adding anything to safety in our country when people are confused and sometimes misled about the correct fuel to use for their aircraft. I was running through the Australian fuel suppliers this afternoon and there are 88 different companies with from 1 to 1540 outlets Of these there really was a Mogas with 19 outlets servicing Regional South Australia and Northern Territory. OTR was the owner and was acquired by Viva Energy on April 2, 2024.

If you study CASA history you will see what the Endorsements were, and how they were dropped. If you go on the RAA site you will see that they do have some endorsements but just a few.

The engines and carburtors were designed for that. With a kero tractor you would get the best result by turning the kero off and just as the engine stuttered, turning the petrol on so it ran on the petrol and kero residue. Start the next morning was instant on petrol and when the engine was warm the taps were reveresed; petrol off, Kero on. On the diesel tractors the fuel cutout was pulled at the end of the day. The next morning the decompression lever was pulled up, throttle to idle and the engine started on petrol for 3 or 4 minutes then both levers were slammed down for a spectactular roar in the bigger models and you were ready for work. It was a nuisance filling with two fuels, and that process was followed by the dedicated diesel where glow plus in each cylinder were held on for 30 seconds or so and there was enough heat to fire the diesel. However, this interchangeability of fuels is a red herring. As a pilot your issue is an engine failure. So your concern is what causes an engine failure and using fuel other than that specified by the manufacturer is the start of where you don't want to go. You may be lucky and get a No Start, so no crash. You may not and get a blockage in the fuel line, the carb, of if fuel injected, in enough injectors to stop the engine.

I'll give you an example; Australia was not able to introduce a CO2 emission level (so Australian cars had no maximum enission level for CO2, like they did for NOx and PM), because fuel quality plays a big role in CO2 test results. You could build a very efficient engine, but the fuels being imported into Australia were so bad that we couldn't get stable CO2 results. In the finish the automotive industry and the fuel industry got together and made an agreement on the standard of fuel which would be imported into Australia goinng forward and it's that agreement that allows Australian suppliers to quote a CO2 output. A second example was diesel distillate where the imported standard being sold in Australia was one of the lowest in the world.

The fuel you use in your engine should NEVER be chosen from a social media platform; NEVER. If your engine stops, you are going down and several people who commented on this site, are no longer with us to emphasise that point. Manufacturers list fuel and oil specifications. They are based on failures per 100 engines, so the manufacturer's recommendation will give you potentially the longest life. It's quicker to get an answer from the manufacturer (not the dealer, because the dealer may get tangled up in the same things as social media posters), than is is to try to pick a winner from the posts. That's the engine. Some car manufacturers will sign off their engines for Ethanol, but they note that they are doing that after signing off the whole car - everywhere the fuel sits or goes. So, for example, If Rotax sign off on ethanol in an engine, that doesn't mean you can use methanol, unless you've gone through every item when the fuel sits or moves to ensure every component is ethanol-proof. No good having an Ethanol-approved engine if it's sucking up a soup of molten plastics and shuts down. As some have mentioned, in selecting a fuel on the market for your country, the RON rating has to also meet the engine specification. And as a guide, whenever you see someone say "I use X", bin the information, unless he adds, after dyno testing 153 engines with this exact same specifications. I can remember one poster here who would post the engine he used and argue they were totally reliable if you did x, Y, and z. (which cost around a thousand dollars. The engines still failed and so did his.

And Ross is that the genuine Mogas or has someone icorrectly labeled the pump?

A subscription to ERSA may cost a lot less, and with ERSA you get updates.

So, with OT's explanation are you going to stop using the US "Mogas"

Mogas is sold in the USA. It doesn't mean anyting not-avgas, it's a specific fuel. Mogas is not sold in Australia. Our refining for cars, trucks, tractors, stationary engines if different to the USA.

Just found the perfect example of windshear on a light aircraft. One of my CFIs was killed by windshear. I've experienced it twice, on late final around 50 to 100 feet above ground level. The first time, I didn't react, just sat there and the Instructor slammed the throttle wide open so we missed going into scrub. The second time, the CFI yelled "FULL TROTTLE" but I'd reached the end of the throttle sector and we went up like a lift. You dont need to know the theory of it; when you fall it's just WOT and THEN fly it. I timed this one at about 3 seconds from the point where he would notice the drop to touch down In my cases I hadn't reached the runway; I counted 1.5 seconds from the time he would notice the drop to the time WOT would have arrested the drop and he could climb out. You can put your stop watches on it and feel how much time you have to react. We've talked in the past about building some actions, like EFATO initial response into muscle memory, where the average person starts to move in about 50/100 of a second, people with full currency and active about 20 to 30/100, and some down to 15/100. If it's not a built in response; if something happens out of the blue, the reaction time will be around 2 to 5 seconds or even longer if you are disbelieving of what's happening. This is a good one to concrete in your head. Remember, I had made countles approaches and landings, but the first time, I would have started to respond after I hit the ground. Windshear

Skua branch sharpened at one end by rotating it between 3 rocks known as a Taupa Crush. The Taupa Crush is related to the Taupa Jaws where the heads of enemy warriors are rotated in this five-stone device and when the warrior has finally been pulled out of the Taupa Crush he has the flat ears and flattened nose and tattoos of beautiful symmetrical design from the Hauraki oyster juices poured int the design. This makes the warriors suitable for living with the conquering tribe and they are then ........

No; I was just trying to give you some help.

...before they made the trips to New Zealand were the most interesting, because the New Zealand Greens were mostly loggers who wanted all the logging profits for themselves and also were not tolerant of any moves to improve Diversity.

That's a Short Field Landing in the PPL syllabus, for when whatever you've chosen doesn't have the rolling distance you want.

So another post, another rude No Quote. I'll assume you were aiming your spleen at me. I'm not backward in being critical of RAA when it warrants it, but they don't have an "attitude" to LL. That's an existiong regulation. If you want to change it best read their Constitution to see what the process is to change regulations, and if you can get agreement and someone to put the motion up, why not do something.

1. It's good manners to use the Quote link, just like I've done here. It's only a single click, then we know what you are referring to. 2. Just so you know LL regulation is not up for debate; just a few people clarifying it. You might be the messenger but that's all the more reason to refer to the Recreational Aviation Australia Rules and quote them.

Low level flying is clearly defined under Recreational Aviation Australia Ltd regulations; very clearly defined. I realise you were talking about the Dreamtime in the past where, if something went wrong for the student practising what he was taught, CASA picked up the tab, and if necessary smacked the instructor on the knuckles. We are no longer in that era.
