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

[/ QUOTE ]-30°C? Must have been summer when you were there... either that or you were in the Tourist spots. /forums/images/graemlins/grin.gif

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

[/ QUOTE ]That's it exactly. Why waste three or four litres? I knew the petrol would be fine added to a reasonable amount of Diesel in the tank, but I didn't realise the possibility of the oil harming the catalyst.

I said it because you said it VicS - several years ago, and saved me getting rid of petrol at the end of each season. But several posts since dont seem to believe it.

My point is it does actually work - so the original poster doesnt need to chuck out his fuel, or risk ruining the cat his car.

I think its called agreeing with a previous post.

Voice of bad experience

[/ 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.

Vics post here quoted ois the best straight advice I have seen for a long while on this oft repeated subject. I second his advice based on my work as Fuel Quality Inspectors.

As to original poster asking about what to do with the fuel ie put in car .... straight answer is No. Unless the car is a pre-Cat car ... which is unlikely.

Lanwmowers, chain-saws, strimmers, all sorts other than car come to mind ... or do as Vics does ...

I in fact don't even go that far ... I just make sure container is tight closed and left in cool corner out of direct light etc.
I am still using old fuel in my outboards going back at least a year !! probably longer !

Main point to remember ... filter the fuel after giving it a real good shake and mix before pouring into tank ...

 

[Guest]

The oil consumption of cars is a quoted max ... afaik ... and if you add 2st fuel to your tank in significant quantity ... then you add to this consumption the 2st mix.
Why do it ?

I have put 2st in my car in emergency to to get to petrol station ... a trip of maybe 2kms ... but made sure I've filled tank to mix down the 3 or 4 litres I put in ...

Why risk it ?

 

[Guest]

Petrol in diesel will do no harm in small quantities ... in fact it breaks up the parafins ..... It is a common farmers trick for winter.

Of course I do not advocate being silly and trying to run a car on high % mix diesel / petrol !!

Oh and manufacturers who say don't do it in their drivers manuals are ignoring industry practice of blending diesels !!

Aye ,I know a bits ok!
Had to get the "Tight Scotsman " script in there somehow.
Farmers?

Red .... White ...... Blue ..... makes no odds - all have similar Cold Properties .... without addition of additive or other "spiker" - you will have diesel of about -5 ... -7C capability only.

It is something based on my own experieces and observations, a bit of chemistry, and what you have said on here before. We more or less agreed with each other on this subject ages ago.

I'd love to know why two stroke oil appears to have caused problems with "cats" though. It would have thought that such a small quantity of oil added to a tank of fuel would not cause any problem, if it did then cars that do burn a bit of oil would soon foul their "cats" A point already made! On the other hand is it really likely that 2T oil contains any additives that would harm a "cat"?
It has to be said, of course, that while respecting the experiences of others, reported here in good faith, that the number reporting problems is far too small to be considered proof of a problem. Nevertheless still best to err on the side of caution in the absence of advice from someone who actually knows the formulation of 2T oil.

Do you have to use 2T oil in 2 stroke fuel. For 30 years I have been using 20/50..DOH!

 

[Guest]

Re: twostroke fuel .... 2T or 20/50 ... !!

Your choice ! But not one I recc'd. 2T is formulated to carry with the gasoline and do its job ... as to what actual difference 20/50 would do ??

It's funny because in days gone by - I used to add Methanol / Castor mix to my Go-Kart fuel ... (Villiers 9E3 engine and 1:20 2T mix ....) ... you could smell it miles away when running ... and illegal in the race. But gave a boost for trials etc.

 

[VicS]

At one time just a straight oil was sometimes suggested as an alternative but at a slightly lower rate. Eg for the Villiers Mk1F engine used in small motorcycles many years ago the recommendation was Castrol two stroke self mixing oil at 16:1 or Castrol XL SAE30 at 20:1.

Multigrade oils are never recommended.

For a water cooled outboard oil for a water cooled engine to a TC-W spec should be used. (Oil for air cooled engines is a little more viscous as they run much hotter.

Almost replied to those questions but then again I,m not too sure either.
But I know a Man who can!
Be reporting back, probably next Week.
Interesting stuff (Well I think so)!
Ref the older two strokes , oil ratios, de blah de blah de blah!
Seagulls, Villiers, and all that there.!
Blimey, we,ve been round the block with this one a few times.
Plus synthetics and tc's etc.
Too much grape to into that lot again Tonight!
But the Cat thing?
Hmm, I shall check
