Oil in Avgas?

[Downunder]

If the oil doesn't stay suspended and mixed and "drops out", you may get a "slug" of oil coming through......

 

Some of the plastic jerry cans don't have a wide enough hole for the large avgas bowser spouts. Make sure it's big enough....

Safest is to stick to the NEW drums and use them ONCE for aviation purposes with the fuel already in them (and a release note).. With plastic I would be concerned about some elements of the container mixing with the fuel unless it was a specially made for use with petrol/fuels product. There's also a static electricity consideration. Plastic is good IF it's the right stuff. Keep the rubbish out of the tank in the first place rather than total reliance on in-line filters..Nev

 

Nev ! where do you get these ideas? You have to have some faith that a fuel contained sold in Au meets the standards for a fuel containing vessel. - no leaching, no static (with appropriate care) I have used my Bunnings units for about 4 years now. Total capacity 100 L but could increase if the need was there - never a problem BUT if you want to splash out, go to 4 X 4 accessory shop - pay big big $$ for a colour codded great looking plastic jerry that will do the same job as the Bunnings cheapo .

 

I cant understand why anyone who would use an old style 44/200L UNLESS their aircraft is so thirsty (chopper??) they will use all the fuel in a few days - anything less is a complete false economy and a materials handling nightmare with added contamination worries.

I use the cheap & nasty 20L plastic Jerry's ($20 from Most outlets) that allow a bowser nozzle to fit, works well for me!

If you use a fuel container for petrol or avgas that is not rated to, and marked as, "AS/NZS 2906 Fuel containers – Portable – Plastics and metal", then you deserve all the problems you get when it fractures.

 

"AS1940 Storage and handling of flammable and combustible liquids" should also be compulsory reading, for anyone handling highly volatile petroleum fuels.

Recalls, back about 1985(?) at MKT there were an aircraft burned from a 20 litre drum fueling mishap. I seen the remains, though weren’t there at the time of fire so don’t know the specifics.

Hi folks

 

Just a quickie!

 

Im thinking about storing 44 gallon drums of Avgas at my home strip. In theory I can buy new drums directly from a supplier (Shell), but anecdotally they will only sell a minimum of four together (apparently to keep Avgas out of the hands of racing enthusiasts).

 

An alternative will be to fill up some pre-used drums at the local bowser. I know a bloke who runs a high end vehicle service centre/workshop. He gets his oil by the drum and so constantly has a turnover of virtually new single use-oil drums. So I can get near new drums for free and potentially just fill them at the Avgas bowser.

 

The question is whether the drums need to be meticulously cleaned before filling with Avgas? If it was an older petrol or diesel engine in a road vehicle, I'd have no hesitation in having a spot of clean oil mixed in the fuel -might even make them run a bit smoother. But what about a Lycoming burning Avgas? Of course I will flush the drums with a few litres of Avgas before filling, but aren't certain I'd get everything. Whats the worst a bit of clean oil could do if mixed into my Avgas?

 

Cheers

People add Marvel Mystery Oil to avgas all the time with actual benefits. So THAT oil seems OK. It is in small portions.

Mystery Marvel Oil...is oil and is added to avgas all the time.
