petrol guage jumping after putting in boat's fuel

[catchy_fishy]

after reading advice that I should burn (in the car - landy) the fuel I won't be using from ,my boat, today i dumped about 35litres of 2 stroke mixed fuel in my landy fuel tanks. (V8 defender 110)

My fuel guage is bouncing up and down since hovering between half and three quarters.

Any ideas

yer...dont go putting premix fuel into your car. I would rather tip it out than do anything like that.

:o yes i agree wouldnt have put 2 stroke in ya car!
what they refer to is unused petrol not mixed maybeuse in ya car! but 2 stroke i would run through ya mower!
even non mixed fuel i run through my mower not the car!

i would say the oil content in the fuel is playing havic in the sender!
as it passes through the oil and fuel! once it is run through it should be ok ,but it might take a few tank fulls! keep an eye on ya plugs as they might fowl up!

come on guys
the fuel tank sender (the only part of a fuel gauge system that is touched by the fuel) consist of a wire coil around an insulated board with a float attached with a metal rod, when the float goes up and down with the fuel level a contact strip contacts the wire coil and sends the signal to the gauge. It would still work if you put 100% oil in the tank.

possibility that you were in a bit of rough water prior to transferring the fuel,,,, and it has retained a memory,,, ;D ;D ;D ;D ;D ;D

and about 2 stroke hurting the engine, not pssible. if when put in its 50:1, add that to another 20 odd lires of esisting fuel it is now at 100:1.
when add after market upper cyc lube, what do you think you are adding.

Don't know if I would be using two - stroke mixed fuel in my vehicle . Some time ago I saw 2 stroke fuel used in a four stroke dive compressor by mistake and resulted in loosening carbon deposits from the cylinders and lodging under the valve seats causing valve problems . Smaller engine yes but if you have to do it keep it well diluted with straight fuel .

I am with Blaze ..been using it in my car for many years...silly to waste good fuel. ::)

Try putting two stroke fuel in a four stroke lawn mower. It only gets down half a strip before stopping.

Electrically I think it could be the cause of the fuel gauge fluctuations

Hi Angla
I run 2 stroke fuel in my 4 stroke mower, have done for years. Blows a bit of smoke but stops the valve stems sticking.

Is your landy EFI?
I don't know if the 2 stroke mix would be safe for the oxygen sensor if it is. Im sure 2 stroke burns at a different air/fuel ratio to normal fuel, so when under load your car may be running too lean. I also guess 2 stroke mix requires different ignition timing than straight fuel, which may lead to detonation under load.

sorry mate i should have pulled my head in :'(

jeez I dream of such issues ....

could it be the tank is over filled & the float forced under - this will give phantom reads

pull the hatches & check the connections too

landrovers will run on crap fuel, even without minor tuning adjustments - its part of their brief -

they will run crap on good fuel & run crap on crap fuel ... ;)


if it keeps bothering you speak to the boys on these boards - http://www.aulro.com/index.php
