Capt Kremen Posted July 13, 2022 Share Posted July 13, 2022 A fellow modeller who has not flown for some time due health issues, wishes to responsibly dispose of old, no longer viable, glow fuel. This is a relatively small quantity, approx 2 plastic containers worth. Local Domestic Refuse Centres vary in their acceptance terms and may levy disproportionate charges if the do accept fuel/oils etc. What do i/c flyers do in this situation?

Ron Gray Posted July 13, 2022 Share Posted July 13, 2022 My local tip allows me to pour it into the oil container they have. 1 Quote Link to comment Share on other sites More sharing options...
Jon H Posted July 13, 2022 Share Posted July 13, 2022 (edited) it makes great weed killer on the path or driveway. You could also leave the bottle open and let the methanol evaporate off leaving just the oil which you can take to the tip Or, keep hold of it for cleaning gummed up engines. Pour some out, slosh the engine around in it and go at it with an old toothbrush. far better than petrol or cellulose Edited July 13, 2022 by Jon - Laser Engines 4 Quote Link to comment Share on other sites More sharing options...

PatMc Posted July 13, 2022 Share Posted July 13, 2022 Is it really effective as a weed killer ? It doesn't seem to have any ill effects on the vegetation in areas where models are refuelled, started & tuned despite liberal amounts of fuel often being spilled in the proccess.

Paul De Tourtoulon Posted July 13, 2022 Share Posted July 13, 2022 I got some of some old carstor mix more than 20 years old, it ran well mixed in with good stuff. 1 Quote Link to comment Share on other sites More sharing options...
Stuphedd Posted August 24, 2022 Share Posted August 24, 2022 Talking of old stuff !!! Going back a few years where as a club we used to make our own fuel I found this invoice from 1978 showing the price of 25lts of methanol !! Quote Link to comment Share on other sites More sharing options...

Not really sure about that comment. Not unusual to see while dead patches along the flight line. Now whether different oils or different nitro content makes a difference. Not model related but I have noticed in the garden that with expensive weed killer the grass on the patio is back in weeks but if you spill a drop of petrol filling the lawn mower that area is dead forever. Sod’s law I guess Quote Link to comment Share on other sites More sharing options...
Lima Hotel Foxtrot Posted August 25, 2022 Share Posted August 25, 2022 Old fuel seems to work better as weed killer. I've tried it with both old and new high percentage nitro. Presumably it's something to do with the molecular change due to age and hygroscopic properties of the fuel that enables it to be more easily absorbed by the plant and travel down to the roots as opposed to sitting on the leaves and only burning the surface.

We used to fly on a sports field where the grounds-keeper was always complaining about "burnt" patches of grass, so the rule was we were to use drip trays if we were using nitro which was the main culprit.

David Davis 2 Posted August 25, 2022 Share Posted August 25, 2022 When people were switching from castor based to synthetic based fuels they frequently used to give me their old fuel. If the fuel was insufficiently combustible I would add a cup full of petrol to it. My old Mercos loved it! Of course I wouldn't use it in my Lasers today! 😊 Quote Link to comment Share on other sites More sharing options...
J D 8 Posted August 25, 2022 Share Posted August 25, 2022 Want rid of old glow fuel ? send it to me and I will put it in my old Land Rover, Happy to run on anything remotely combustible.😄 Quote Link to comment Share on other sites More sharing options...
Graham Bowers Posted August 26, 2022 Share Posted August 26, 2022 Why "no longer viable"? I didn't fly glow for a good while and am using 5% nitromethane 20% castor fuel that's over 10 years old with no problems. 3 Quote Link to comment Share on other sites More sharing options...

Sorry Graham, but there will be members on here, now in A and E with hearts attacks since you mentioned castor and Nitro, My suggestion is that you go to church on Sunday or better still go this morning and start asking for forgiveness from them🤣 .In the mean time carry on using your fuel and enjoy the flying.

It's like wine, 10 years old and it is still a bit early to use, maybe the nitro has evaporated but still good to go. 1 Quote Link to comment Share on other sites More sharing options...

Yep, I'm on my last gallon of some 10+ Southern Model Crafts 0% synthetic (I think it has 2% castor), looks like ribena, but the engines that don't need Nitro run just fine on it, namely some old Lasers and an OS AX55. I do dilute it a bit with some neat methanol just to get the oil content down a bit. Quote Link to comment Share on other sites More sharing options...
