It doesn't mean anyting  not-avgas, it's a specific fuel.

Mogas is not sold in Australia.

According to Wikipedia,  mogas is "a slang for common gasoline (for cars, motorcycles, lawnmowers ...) used by aviators to distinguish it from avgas".

According to BP, "Mogas is otherwise known as motor gasoline, is used by ground vehicles, while Avgas is specifically developed for aircraft use"

 

Neither indicate it is a specific fuel different to what is available in Australia. Unless you can point to an example that shows Mogas actually exists as a specific fuel, I'm inclined to believe BP rather than just your say-so.

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.

This is a Chemical Company Ad.

It may be approved by FAA, but an owner, pilot of an aircraft should be looking for the approval of the engine manufacturer, who does the failures per 100 engines on the dyno tests. 

 

That's not to say the product (a) hasn't been through those tests or (b) would not have passed them.

Hi Moneybox,

 

What is your interest in Decalin?

 

It's been around for quite a long time - seems to be aimed at minimising lead deposits in aircraft using leaded fuel.

 

I do hear of Rotax owners, using predominantly/exclusively AvGas, spruiking its efficacy.

 

As far as I know, its use in Rotax engines, does not extend the 600 hr gearbox inspection, when Avgas is used.

 

Better to stick with ULP and avoid the added cost & bother of Decalin😈

[facthunter]

That is not always possible. The rate at which Decalin is added is small, 1 ounce /10 us gallons. It's essentially a solvent.  Nev

No interest Skippy, just wanted to throw something into the argument 😉 on something I know nothing about.

MOGAS just means auto fuel, its not a specific brand/grade or type

Thanks for that; as we see from the USEPA document the areas where MOGAS and GASOLINE are supplied are defined. From that point the blending to suit the two market areas is up to the refineries and wholesale companies.

[skippydiesel]

Disclosure - I could not view the whole video, dreadfully slow/dreary delivery and several factual errors, near the start, put me off.

 

The video confirms that MOGAS is just one more US  derived name for automotive petrol. Would seem to be quite generic ie is not limited to a particular type/blend/standard,  other than having an AKI of 91 - speculation; may have been invented/created by a fuel company marketing department.

 

For the most part the video is not applicable to Australia, its climate/terrain and fuel types.😈

MOGAS is a BRAND name in Au and they sell diesel etc Nev

Who cares? It all seems like marketing hype to me. So MOGAS is anything that isn't AVGAS.

Yes -  just simple colloquial terminology.

During my career I visited every oil refinery in Australia - when they existed. All of them produced ‘mogas’ as it was known by the refinery operators. Only a few produced Avgas.

Mobil was notable for making some that grounded a lot of Planes, some permanently. Had Caustic still in it..   Nev

Not caustic.

It was an over-dosed neutralising amine that was used to minimise corrosion from acid carryover into a distillation column downstream of the H2SO4 reactor in the alky unit. It was over-dosed because the reactor control was poor leading to foaming and carryover.

The residual amine present in the produced avgas acted as a solvent on some aircraft fuel line components.

[facthunter]

It didn't affect Just Fuel lines.  Nev
