Mogas is sold in the USA.      

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.

Decalin RunUp is approved for use with the new 100VLL (Very Low Lead) fuel announced by the FAA on Special Airworthiness Bulletin NE-11-55. 

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😈

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
