Hey, so I've a full 5l can of two stroke mix to dispose of. Can I just pour it into my car petrol tank?
You sure can!!!!! Just don't expect it to ever run again
That has to be a joke, 2 stroke oil has urm...oil in it!!
If you put it in a 4 stroke car it will run like a bag of spanners and you will also be shelling out for a new fuel injection system!
If you have an older car with a carburettor and without too much electrickery, it should be fine, especially if it's diluted further by the 'clean' petrol in the tank. It'll be a bit smokey, depending on the strength of the original premix and how much clean petrol it was diluted with, but it won't do any harm to the engine or the fuel system.
If you have a more modern car with fuel injection and all manner of electronic engine management and catalytic converters and stuff on it, I'd be very shy of doing it.
Find somebody with a 2-stroke bike, outboard or lawnmower or something and give it to them. A standard 4-stroke petrol engine isn't going to benefit from it in anyway so why run the risk.
Im fairly sure that apart from smoking a bit it'll do no damage at all except put on an emission light on the dash. Infact it'll probably oil up a few bits that might need it
I hope thats more joking?
Assuming the mix is 1:50 (thats 100 ml oil in 5 liter) and your tank holds another 45 liter of fresh petrol, the mixture is then 1: 500 ...that's a homeopathic dosage ...just lash it in there, won't make any difference.
(unless you actually believe in homeopathy, of course )
Are things REALLY that bad????
I wouldnt put it near it, it will contaminate your Lambda sensors and cause problems with your injectors.
For the sake of 7 euro of fuel, you could cost yourself hundreds. if ya have a lawnmower or a chainsaw, fill them up with it or maybe a neightbour might be glad of it if you need the container.
Ive heard of people putting a small amount of two stroke into wankel engine cars alright though
Injector tollerances are measures in one thousands of a milimeter so having contaminants, of any sort in fuel will not end well!
