twostroke fuel

[explores]

At the end of the boating season and i have some twostroke fuel left, can i put it in my car to use it up or will it be harmful.

 

[ChrisE]

Yes, no probs, do this every year.

"At the end of the boating season" - did I doze off and miss a couple of months?

Nothing to stop you putting it in your car but be careful if you car has a "cat" /forums/images/graemlins/grin.gif Voice of bad experience and a £250 bill to change the poisoned "cat" - better put it in the lawnmower or save it 'til next season and add some fresh mix if necessary.

[/ QUOTE ] I have often wondered.

I do usually use it up in the lawnmower if it is only a small amount but often I end up with about four gallons. In that case I transfer it from the plastic outboard tank to two metal jerry cans with tight fitting caps. You should not store it in the plastic tank anyway but I believe lighter fractions can be lost through the walls of plastic containers and that oxygen can diffuse through the walls and oxidise some constituents. Metal containers prevent both of those possibilities. I also minimise exposure to air (oxygen) by only storing full cans. The cans go in the shed at the far end of the garden

Before use I always filter stored fuel through a fine filter and mix with an equal volume of fresh just to be on the safe side.

i forgot about about the oil in the fuel at easter and was running low on fuel so decided to use the 20ltrs of pre-mixed in the new car. a bill for £411.00 for cat and a sensor

Ooooh, bet that smarted a bit. Still I rest my case and nice to know I got off "lightly" /forums/images/graemlins/grin.gif 'though I am sure other ex-purts will come on saying "no problem, sling it in the car" /forums/images/graemlins/wink.gif

At the end of the season I store my fuel. At the beginning of the next season I filter the 2 stroke with a fine mesh funnel and put it back in the outboard and it works fine - even better if the black outboard tank is in the sun, as this stops the sticky clear precipitate, which gums up the carb on my Suzuki 2.2.
If I dont do this, the outboard either wont start, or starts and cuts out, which means I have to open the screw and the bottom of the float chamber and dump the contents.
So in summary, keep it, filter it, better still blend it with new.

Never needed to do this with the Seagull tho'

If putting 100:1 mix oil/petrol in a car damages the cat how do Mercedes and Volkswagens engines survive when their dealers say oil consumptions of a litre per 1,000 miles (they say this is acceptable in a new car, and quite a few new cars run at this rate). I work that out at about a 1:125 mix being burnt. And that's on a new engine.

In practice a gallon or so of 50:1 or 100:1 mix into a tankful of petrol is surely insignificant in comparison to the oil a car burns anyway.

As my car's diesel I now can't use it up this way, but in the past I've always just used old 2/S up in the car.

Risky if your car is fitted with a "Cat", the oil won't do it any good.

Oops. I put some old two-stroke fuel into the car last year, but it's gone through MOT since so I guess the catalyst is OK. That was a Diesel car in case that makes a difference.

For those not so lucky ....

Presumably the two stroke fuel was well diluted with the diesel.

Excuse Me, did you say You put petrol in a diesel?
Sorry, just noticed Aberdeen in your Av.Scotitsh fuelgruality? /forums/images/graemlins/grin.gif

 

[paulm299]

Used to put petrol in with the diesel in Canada during the winter , As long as it is only about a gallon to a full tank of about 100 ltrs . So you should be alright in a diesel if you only use a couple of litres at a time .

Like I said - Some "Ex-spurts" would come along and say it was O.K.......... /forums/images/graemlins/ooo.gif

Thanks for your advice, I will do the filtering bit and use it next year in my outboard. (with some fresh).

when i spent a long winter many years ago in alaska i was told to add 2 ltrs of petrol to the 10 gallons of deisel in my very old deisel pick-up to stop gumming up at -30c

Store it in a full metal air tight container, and it will be fine for use next season. Cats tend not to like oil, so its probably not worth risking damaging it. Plastic containers will work, but should be stored in a dark corner. Having been involved in a major refit this season, I am still using outboard fuel bought at the beginning of last season.
