Both des and I didn't see the units of measurement as you have pointed out thats why it looked wrong, but 0.8 litres per miles is good espcially if its the red stuff, now if we could just buy it from JW we would be laughing, 64 ppl at Gosport the other day.

Opps didn’t spot that

I’m so used to seeing consumption expressed in ltrs per NM I was all confuses

I think we should all talk the same language.... HENCEFORTH it will all be in

LITERS/HOUR with a quoted RPM and speed of boat

liters/mile = doesnt mean much as it too dependent on conditions

God has spoken!!!

Just because you are Europeanised doesn't mean we all are - what is wrong with gph??? Or gpnm or even milkbottles per millenia - as long as people make it clear what figures they are using!!!

eupa · 23 September 2005, 15:27

with the new eurapean way of measuring cars consumption figures in (litres per 100 kilometers

thats my boy Roy.. spot on - throw it at 'em. especially if you have to talk
about us gallons and imperial.

In fact last year was in Canada - now thats a problem

Quebec - the enlighten part use liters
Ontario - use liters and imperial gallons
and
some parts use imperial gallons and us gallons.

Dont know what you are doing half the time ......

I knew you would say THAT................ but it would be nice if we all used the same language.. Do you speak welsh???
I am not particularily preaching the case of Europe dominus- I find it easier
to use metric than other stuff. Look at the measurements for hand tools

- inches,
-witworth
- af
ect..

a nightmare

The only problem with quoting litres/min or hour at a given RPM is that you need a fuel computer!! I haven't got one, so the only way I can do it is as an average of engine run time and how much diesel I put in each time I visit the fuel pontoon.

I was just sharing my average consumption figures for general interest.

wasnt knocking you Dylan..... but if you can afford a 300hp rib then you can afford a fuel meter. I am not talking about a fuel computer. You can pick up a decent one from Flowscan in the States for about $270 - that will give you
liters/ hour + accumulative, and you can then calculate how much you have left in the tank. Its +/- 3%. and relative easy to fit. For me its a MUST - as to run out of gas in the middle of the channel doesnt do my ticker any good!!!!!!!!!!!!

Johnthan, please tell me were I can get a diesel fuel flow meter for $270.

You could buy a central heating oil tank and get your diesel delivered in bulk. Nothing illegal in that. Whilst it's a bit of a hassle, it's not a major problem to transport 5 or 6 jerry cans to your boat.

Last week I was quoted 33.7p/lt for 1200 lts. You can get a very neat 1200lt tank for about £120. You could buy the fuel and the tank and still have a couple of hundred qwid change rather than paying 64p/lt.

So I take it there is not any side effects of running your motor on heating oil..? I was lead to believe that there was less “lubricant” in a heating oil. Hence why I have not got the Audi tank filled with the stuff…

jwalker · 23 September 2005, 21:05

Er, mdt, read my first sentence again.

Kerosine is possible with a bit of modification but it contains less energy than diesel and it's illegal. Costs just a couple of pennies less than diesel, so there's no point...... at the moment.

Oops, did I say that?

He meant red diesel

Talking of heating oil though it is kerosene which is the same(near enouh) as Jet fuel.

Some armies now have a one fuel policy to cut down on logistics probs - in other words they use jet fuel in tanks and 4x4s etc as well.

In really cold countries they sell winter diesel which is just kerosene!!!

Yes it does lack a little in lubricity compared to diesel but only becomes a problem at high temps like in the gulf. A way to overcome this prob is to add a small amount of atf or cooking oil to the fuel - say 1L per 20L of fuel.

Basically - despite what some people WANT you to believe - there is no prob in using it but it is just as bad as using red diesel - get caught and you are in very deep doo doo!!!

Codders
Heating oil is NOT kerosene( Kerosene -paraffin is the same)
Kerosene and Jet fuel ( Jp4) are the same
Diesel is HEATING OIL
Heating oil has a red dye added to it -to stop it being used for automotive use.

You can run ANY diesel engine on red diesel- it will not be affected by the colour!!!!!!!!! Farrmers are permitted to use red diesel in their tractors

Diesel can be mixed with kerosene - and is done mainly in the winter months
to stop the formation of wax-crystals .Normally 10 to 20% is maximum- but this is mainly history as most diesel-fuel is treated with additives that make it good to -20deg. cent

the real point is to get rid of the red in red diesel......................

Both kero and diesel are heating oils. Kero is common in the UK.

Diesel for heating is generally called gas oil and it is red. It is not the same as road diesel and can be recognised even if the dye is removed.

Kero in bulk is not coloured but when sold as paraffin it often is. Remember Esso Blue and Pink Paraffin?

It is illegal in the UK to add kero to road diesel.

codprawn · 24 September 2005, 14:31

That's right - in the UK central heating oil IS Kerosene - so before you try to shoot me down in flames Eupa PLEASE try to get your facts right - I usually do!!!

Actually Kerosene IS now coloured - with a yellow dye the Europeans made us put into it - before that it LOOKED exactly the same as normal diesel. The yellow dye isn't very noticeable but it is there - also an invisible marker is used called courmarin that can be detected in a lab.

When they used to do a simple visual test you were fine but they introduced better testing because of the doctored Irish diesel.....

eupa · 24 September 2005, 16:56

so before you try to shoot me down in flames Eupa

Codders would I realy ?? - You do have a suspicious mind....
any way the problem is definitions.....

Pete- just seen this - will send you PM on Monday- doe you need the twin motor one or the single motor one.
