The fuel circuit in a 912 iS includes dual redundant pumps, an 8 micron filter after the 40 odd micron gascolator and its pressurised when running to about 45psi and a flow rate of about 70 l/h ( > 2X maximum flow). There is no air access to this system, the only air contact is on the free surface in. the fuel tanks. Murphy’s law therefore suggests some new failure mode will apply one day instead of “gum in carburettor passages”. 😞

I'm not saying you shouldn't buy automotive petrol (mogas is an American term that shouldn't be used here).

Agree; Mogas is a name applied to gasoline refined in the USA

It comes in three standards:
Regular: 87 octane

Midgrade: 89-90 octane

Premium: 91 - 94 octane

Octane rating is to the US standard.

That might make some better sense to any US owner reading this thread

Australia

Australian petrol is refined in Australia and overseas to the varieties we have been discussing.

Use only the petrol recommended by your engine manufacturer.

What some of us had been discussing on another thread, and this one were the traps to can be caught with when buying different grades of petrol.

It's not such a problem if the engine simply won't start, but if you start changing things or airways become gummed up, you can't just roll to the side of the road; you're going to be faced with a forced landing, perhaps an EFATO and you have to pull that off. Better to talk to your manufacturer.

Geez, after all this I am probably not game to buy Mogas  from anywhere for my plane 🙂 

Some of this is BS. It's very straightforward; you get the recommendation straight from your engine supplier, never from "the man in the video".

One aspect possibly overlooked when topping up tanks with fresh Mogas: if there’s still fuel in the float bowl(s), that’s got to spark up first, before the fresh stuff gets drawn in.

 

 

I've found it doesn't take the full bowl.

I've had four or five attempts with no sign of a fire up, then realised the inevitable, put some fresh fuel into the tank, waited five minutes or so, come back and first turn of the starter get a fire up, then dies but second starter attempt fies up and runs.

Between starts? One - two weeks.

95 RON

I wouldn't expect you to have start problems with 95, however:

Depending who supplies it can have ethanol in it, and you don't want ethanol gumming up air passages and eating components, so you need to have the guarantee there's no ethanol. If ethanol gums up an air passage which has been plugged during manufacture (ie no screw at end) - you can finish up having to throw away the carby. I've been caught on a couple of engines.

98 RON 

For starting within two weeks I wouldn't expect you to have a problem because that's the threshold where the problem starts.

That's based on Start 1: start with new fuel, Start 2: start with Start 1 fuel then refuel, or refuel before Start 3 (fresh fuel again).

If you are getting starts with fuel older than two weeks you can join my club where some engines will become difficult to start, four weeks fuel-injected Chev 350 doesn't fire, some engines (60 year old Ferguson with Standard engine) fire instantly.

Yenn -to have your start problem,  there must be something else going on - its not the unladed fuel (unless you got a bad drop), 

BP Super hasn't been around since the BP Super Show featuring artists like Bob Dyer and Rolf Harris, so you need to be very careful to identify what you put in and whether it was a grade containing ethanol.

On this link click on the BP Ultimate 98 link. The starting problem after two weeks sounds like aromatics evaporating off.

Note that it is not recommended for aviation.

At the pumps it's also branded as "removing deposits" so that could also be a problem after avgas.

You do a good job but I'm not convinced that 2 litres added to half a tank will make much difference. 

Yes it does, I've been successful binging a dead engine to life after finding half a litre and putting it in with about 30 litres.
