intermittent missing. (E10?)

It needs an aircraft style poppet valve under the tank where a nozzle on a bottle is pushed in the valve. Water drains test. Done in a daily inspection. Maybe all cars will have it eventually.

Bung a set of Bourgicord leads on as the Bosch ones are useless !

Dave (Laird Scooby) will be along shortly I'm sure to tell you what ratio of meths etc to use in the tank to clear it out if you don't fancy losing your fuel for it to potentially not be the fault.

No, I wasn't agreeing that water in the fuel tank might be the problem, but I cant imagine it would do any good.

Sorry for the misunderstanding I may have caused,Im gobsmacked that there may be water in the fuel,hence the "water in the fuel lines?" surprise

For some reason, the forum won't let me post my longer reply, go to Toolstation and buy 2L of meths and add it to ~1/4 tank (no more than 1/4) of fuel, drive until it's nearly empty then fill up with Super unleaded/E5 and don't use E10 again as it has a higher water content.

Hopefully this post works!

As a result of this thread, i just went to Toolstation and got 2L of meths and added it to my tank. I have also been experiencing an intermittent misfire and down on power even when hot and to be honest, i should have thought of it sooner.

I had half a gallon in a can in the back anyway from my last trip to fill up (i'd left things a bit late! ) so i added the meths to that and then added all of it to the tank.

Fired up after turning a bit more than usual but it was a hot day and as i was thinking i may have to try again, it caught and idled smoother than it has for a long time.

Drove out of the car park and put my foot down to pull away and surprised myself - it went better than it has for a long time too!

Overall a vast improvement! Of course, the acid test will be when it's sat overnight and how it performs from cold tomorrow but so far so good!

I'm not doubting you Dave, but methylated spirit is just ethanol (called wood alcohol in the USA) with a bit of methanol added so people don't drink it - and I think often a bit of water as well in non-industrial brands.

Perhaps this works, but adding more ethanol to get rid of the ethanol seems odd, that is all.

It looks like E10 is meant to remove water itself from that information.

Thank you for that article Luke, that was exactly my thinking. Adding more ethanol to the ethanol doesn't make all that much sense.

The last line from that article that actually confirms what i said :

More ethanol equals more opportunity to dissolve more water and eliminate it by ingesting it into the engine.

It's not adding ethanol to get rid of ethanol, it's to get rid of excess water in the plastic tank. Unless the tank is completely sealed (i.e. no breathers in which case the tank would crush itself due to vacuum when the fuel is pumped out) then atmospheric gas gets in which in this humid weather, is laden with moisture.

When it cools down at night, this moisture condenses out and drops to the bottom of the tank. The ethanol in the petrol isn't always enough to deal with the water. This short video explains how you can use water to remove ethanol from the petrol, as i don't propose people fit a drain tap to their tanks and drain the condensation from the bottom of the tank, adding meths to remove excess water is an easy fix.

Even my dog noticed the difference in how my beast was running last night, as i said above though, the acid test will be later today when i take her out if it drives smoothly without misfiring.

We will have to agree to disagree about that one Dave, the last line of the article actually says:

However, a simpler solution to the problem would just be to fill up occasionally with E10 fuel (provided the car is compatible with that fuel). More ethanol equals more opportunity to dissolve more water and eliminate it by ingesting it into the engine.

... adding 2l more ethanol to the 5l that is already in every tankful of E10 would mean the OP running his motor car on E14 from time to time.

Water in the OP's fuel is a red herring.

Another lovely day in paradise.

No, Alan, the last paragraph says "However, a simpler solution to the problem would just be to fill up occasionally with E10 fuel (provided the car is compatible with that fuel). More ethanol equals more opportunity to dissolve more water and eliminate it by ingesting it into the engine."

Note the full stop after the first line, this makes the last line exactly as i said in the first place.

Unleaded petrol has a naturally higher water content than real petrol. Unleaded with ethanol added has a higher still water content and the more ethanol added at manufacture, the higher the natural water content. The ethanol in the fuel will only cope with the natural water content, not the added water content of atmospheric air in the tank condensing and adding more water to the mix.

I've been using this fix for over 35 years and it was passed down to me by someone who started in the motor trade in the 60s, if not before.

Please don't condemn my (or others) suggestions as red herrings when it has not been proven either way. We have had many nay-sayers like this in the past, particularly on this subject and when the person that has the problem has run out of all the other options, they've tried my suggestion of adding meths and lo and behold, it's worked.

I'm not saying it's always the solution but in this case it sounds very like it might be, if it isn't it's eliminated another possible cause and in the great scheme of things, costs very little.

As for adding 2L meths to 10 gallons of fuel, if you had read what i put in the first place you would have realised this isn't the case.
