I now have a 4 stroke outboard and still have a half full can of pre mixed fuel that I no longer need. I have had it for over a year so not sure whether I would even want to give it to someone else in the marina. Question therefore - where can you dispose of petrol?
 
So long as the container is sealed and its not more than a year or two old, I have never had any qualms about just mixing it with the new fuel each season. Our two stroke never complains either so I am not too convinced about the worries people have. Find someone with a two stroke and give it to them?

Have you got a petrol car? If its an older one (or you know someone with an older one, then by the time it gets diluted down in a whole tank of fuel I don't imagine its going to do anything any harm.) The reason I say older is that I am not sure what two stroke fumes would do to a catalytic converter and wouldn't want to risk that... I'd have stuck it in our old MG and thought it was probably doing some good!

Do not put 2 stroke fuel in a car with a cat. It will destroy the cat in minutes.

Try & find someone who has a 2T lawnmower would be my advice.
 
100:1 mix? just mix it 50/50 with fresh fuel and bang it in your 4st ob - will give it a little "upper cylinder lubrication" - I have done this before when running low on "uncut" petrol for the 4st petrol genny - no problem at 200:1. I agree with others - do NOT put in any engine with a catalytic converter - the oil could poison the catalyst.

Are you sure about this Cliff?

The pre-mixed 2-stroke fuel will presumbaly contain about 50ml of oil. A typical 4-stoke engine will probably burn at least this much oil every 1000 miles and do that year after year and still pass its annual emissions test.

Now they tell me!

I did it some years ago, just a little at a time with full tank of ordinary and it still passed it's emissions ok, so perhaps it's not that bad.

Same here I had about 2 litres of 50-1 mixed petrol I wanted to dispose of. Mixed a litre at a time with Approx 50 litre fill up so giving 2500-1 dilution. It didn't cause any problem.
 
Give it to me

I'll use it in the Seagull or one of the lawn mowers or even in my cat free car

Whats in 2 stroke oil that's not in car engine oils and which will poison a cat ?

Seagull!!!! Seagull!!!!! Who said Seagull!!! Grrrrrrrrrrrrrr. Damn filthy poluting piles of 1920s garbage!!!

But they were made in Blighty so must surely be superior to all that new fangled foreign muck?

Proper legal disposal is a night mare. I bought a boat that had some serious dodgy petrol in it... After trying every which way (10 ltrs brown liquid). Getting caught at several oil disposal points (you cannot put that in there! :eek:).

I tried using it to burn some tree stumps it just about caught...

Official disposal is nightmare!

I don't know the answer to that. All I know about two stroke oils is that they have a high boundary lubricant content, presumably sulphur based, but a very low ash content. This suggests that the sulphur is not in zinc salt form as with other boundary lubs. But maybe I'm wrong and it's the zinc that does the damage?

The same oil thats cracked to form petrol! I totally agree with you.
Sounds like an urban myth, plus as someone else said, car engines do consume oil and dont destroy cats. If anyone is really concerned, do as others have suggested and dilute it a bit at a time, I used my old 2T in my new 4T suzuki a bit at a time with no probs.

It an often debated/ discussed topic but earlier in the thread Giblets said, "Do not put 2 stroke fuel in a car with a cat. It will destroy the cat in minutes."

Its the first time remember anyone being so emphatic about it, "in minutes", so I was wondering if he knew something the rest of us don't. I was hoping he would come back with some sort of explanation.

Its a bit like the email that arrives breathlessly, with thousands of CCs, beware of the new virus that will format your hard drive, feck your wife and devour your daughters or something like that!
