IF i ran my car on 5lt of 2stroke to get to a servo could i have done some sort of damage to it, or will i have lost a great deal of power?

Theres no problem doing this at all. Think about the fuel used in private planes, its basically a 2-stroke mixture.

it is likely to just blacken the plugs. and give the top end extra lubeing
might smoke a little too
i cant see any damage being done

jsut asking the question cause i used 2stroke to fuel my car just as i did a minute burnout on oil, and now its running reallly rough, just trying to narrow down the problem, i changed the sparks and checked the timing and it all seemed to be fine but the car is running really rough

WTF? "Private planes" (I assume you mean light planes) run on Avgas which doesn't resemble 2-stroke at all...

You've never heard of people mixing their own fuel? Caster oil?

hmm sound slike you fucked your engine by runnign ti on 2 stroke and trying to do a burnout....
live and learn perhaps?

Yes I have, but how does that make 2-stroke the same as Avgas?

Theres nothing special about avgas, its just cleaner(more refined). Avgas+caster oil= 2 stroke mixture.
Also a few years ago avgas was not available to everyone so pump fuel and caster oil is all that was used. In fact a guy at my work still uses pump fuel and caster oil in his cesner(spelling?).

Um, I suggest you go to a fuel distribtor's web site (eg www.bp.com.au) and read up on the specs; Avgas is and always has been totally different to pump fuel. The main difference is Avgas has shiteloads of lead in it, which is why it has way higher octane than pump fuel!

castor oil/methanol/nitromethane is commonly used for MODEL aviation fuel.
mixing castor oil with petrol, is in a way similar to mixing petrol and diesel/kerosene. the slow burning characteristics of avgas might be recreated by slowing down the petrol burn rate with the castor oil.... (remember, it's not all about octane rating..(ie detonation resistance) it's about burn rate as well)
since planes generally have large bores and low rpm, they need a fuel that will burn evenly and not have an accelerating flame front, (which, when it collides witht he cylinder wall, pings). avgas is designed to be both detonation resistant AND slow burning...
not to say all the race kiddies using avgas are wrong, but they may need to up the advance significantly to take advantage of it(or up the compression ratio and heat to increase burn speed)
but anyway, we have digressed.. again
2 stroke will just make smoke and deposit carbon in your motor.. you may also find the oil gums up in your fuel lines and carby.
ppl have accidentally filled new cars with diesel and survived, so why would a bit of oil kill your motor (and isn't that the norm for old corollas anyway )
if your motor died, it's more likely the abuse from the burnouts.
no offence intended but.....
burnouts on oil = fried motor = idiot in my books
and it's cessna

as above.
2 stroke wont kill a motor.
but I mean really, if you've put a bit of 2-stroke in your car to get it somewhere and you know it's not supposed to be in there, was it really a good idea to do a burnout running it?

Caster oil mixtures was all that was used in real planes a fair few years ago(you may not be old enough to know this) and it still used a fair bit these days.
