Thanks for the above.
For the sake of a few quid methinks it makes sense to dispose of the fuel

If you have a diesel landrover chuck it in with a bit of cooking oil - it's what I do!!!

Stale Fuel or Water in Fuel

I leave my boat stored ashore in a shed in Spain. Over the winter months this can be for 5 or even 6 months whilst it may be 6 or 8 weekly intervals in the summer. When in use it may do 5 or 6 hrs a day everyday.

When I store it I usually try to brim the 170l tank to stop any condensation although if I expect to be back in the next month or so I donít bother. 170L of fuel is a lot of Äs tied up so in a way I would rather leave it MT.

So full tank and fuel goes stale or empty tank and I pick up condensation in the tank and so water in fuel.

What in your opinion is potentially the worse of the 2 evils? I had instinctively thought water in fuel but perhaps I am behind the times.

Perhaps I should say I do use the Quicksilver fuel conditioner as a mater of course and have always assumed for an Optimax that would be OK. I havenít noticed any residue build up in the filter but it may be in the fuel lines and I havenít spotted it.

Can't you just put some octane booster in. Thats all I do if I'm in any doubt about the fuel.

I love the Internet, but isn't it funny how everyone always has different opinions on exactly what's the "best" thing to do

we need a fuel expert to give us a definitive answer

Gasoline is best kept out of sunlite and open air also kept in cool places to remain fresh but from the moment it is made the life of gasoline is aprox. 2000hrs (3 months). Afterwards it starts to loose its octane value if left sitting for too long a period of time. left sitting over the winter in the engines, well vanish like deposits accumulate. Those varnish deposits is the #1 cause of engines not starting come spring time or performing badly.

In most basic engines using old gas will work unless its years old but for high performance engines and especially with high compression you could burn out the motor.

And using stabilizers can work for a while but only if added when the gas has been just purchased. Trying to use stabilizer after 3-6 months is a waiste of time.

Cheers

Well it was evident on the first run out after winter storage after the conditioners use, If you've had a blast already this season, and you are running on fresh juice now, you should be ok .. dunno whats in the stuff .. it doesnt even smell that aromatic

I have a plastic inboard tank fitted with a breather that lies at ambient temperature, for 6 months during the winter, with a small amount of fuel in it, and I have yet to see a drop of water in my fuel, and I check the filters fastidiously And its not because the outlet sits off the tank bottom either because I have a fuel extraction scheme for supplying the aux if the aux tank runs out, which is a suction hose into the tank bottom and I check the output from that too with no problems thus far

How/where do you dispose of old fuel?
Too much to save until bonfire night, both my cars are diesel not petrol, lawnmower doesn't use that much, etc...
With local councils being tighter and tighter on what you can dispose of where do you dispose of old fuel??
.
Great thread re things to try with old fuel if you want to keep it, but at £15.00 for 1/2 a tank full, may not be worth the cost to try and save the petrol vs other costs and engine running issues(?). Agree with scoobysnax.

If your cars are older diesels then just chuck it in the tank. A few litres into a full tank now and again won't hurt and actually helps in the winter. To be safe chcuk in a litre or 2 of cooking oil as well - and yes I AM serious!!!

I often get free fuel from a mates garage this way cos most people are too scared to use mixed fuels.
