R/c fuel in a petrol road car
Dont worry, it was only a thought!!
I was having a tidy up in the garage the other day, and came across 2 5ltr of 5% rc plane fuel, that i probably wont use
and wondered what would happen if i stuck it (not all at the same time!!) in my 7 's fuel tank, and ran my xflow on it
Any one know ??

RC fuel has some pretty nasty chemicals in it.... I suspect it would bugger up seals/injectors etc..
Anyway, it would be better in a diesel I suspect...(as thats how most RC engines work!)

Smoke, like a moped, with oil in there too.

Your RC fuel will be methanol with 5% nitro-methane, and anywhere between 30% and 20% caster oil(for the two stroke engines). These days the caster
will most likely be a synthetic substitute.
2.5 Litres of that in a 30 litre tank won't do any harm, but for the caster oil making it smell and maybe a little smoke.
DON'T DO IT IF YOU HAVE A CATALYST.
We used to run a similar brew in the sprint cars, leaving out the caster, and adding <1% Castrol M. When things got competitive, the nitro tin
would 'spill', and end up with up to 25%, for a bit more oomph.
Cheers,
Nev.

Very few model engines are diesels these days, the majority are glow engines which is what the OP's fuel is for. The diesels use ether based
fuel (i.e. the stuff in EasyStart aerosols), and you have to adjust the compression ratio to just the right point to get them running properly.

Glow enginers are a form of compresion ignition semi-diesal.
- Methonol isnt very like either petrol or diesal, sort of nether really. urrrrm.
- It burns well squirted out of a garden/parts sparyer with a lighter held infront.

We used to stick old stuff in our lawn mower Made it start easy.
As has already been said, its mostly methanol, something around the equivalent of 120 octane. Wont do any damage in small dilutions.
Either that or use it for lighting fires...

I think Top fuel dragsters use it.
Methonal is the main part.
One other thing is the air fuel ratio is way different. So much bigger jets.

We put a bottle in my mates old Metro. Apart from a slight smell, there was no noticeable change in performance, until he did a handbrake turn, and
the wheel fell off!

As Flak says, its great for starting things that don't want to start - a quick squirt in the intake and away you go.

They don't work with a glow plug, so can't be a true compression ignition engine.

Remember a mate putting it in his Kawasaki AR50 (Yes i know it was a long time ago) he must of put quite a lot in because after a quick thrash up the
road he turned the ignition off and it kept running can only assume the plug must of been glowing

Up to 90% Nitromethane/10% Methanol for top fuellers!

Woops
Did not realise the ratios are the reverse to top fueler's.
Rc planes use from 0% up.
Most normal/sport flying use between 5 and 10% nitro.
I think RC cars use a bit more nitro.
Just had a google on top fueler's. 1.7:1 fuel ratio, and 4 litres / second ouch!

Model cars use to use up to 60% nitro, but now they're generally on 16 or 25% (costs/health/environment issues).
Many years ago i tried to run a bike on 25% model car fuel, straight no petrol. It didn't run properly at all, but even so it had more power
than the clutch could take!.
