The deposits are the unleaded petrol degrading Gerry. Some of the components (petrol is a relatively crude mixture of hydrocarbons) oxidise and become insoluble.
After my interest was piqued by this thread I’ve read around the subject. The advice for unleaded fuel is that its best used with an additive in garden machinery because it degrades in storage. Unleaded also absorbs moisture when stored which makes starting the engine harder and harder. Briggs and Stratton, amongst others, make an additive specifically for this purpose. The additive can extend storage times for fuel by up to three years. Without the additive storage time is limited to four to six months. This advice is repeated on several manufacturers websites
From a personal viewpoint whatever we have left at the end of the season goes into Sue’s car. forg two years ago and have half a can of petrol water than is no good to man nor beast. :loudly-crying: I will have to change my system soon though as she’s buying a diesel, so from next year I’m using an additive :surprised:
It isn’t an issue when unleaded petrol is used in cars, by the way, because the petrol is used relatively quickly.

Tim, I store petrol in a sealed metal jerry can, doubt that any evaporation takes place bang the sealing lever and the lid pulls down airtight

Until they come up with an electric vehicle that will do 350 miles minimum during winter (lights and heater going) without charging (sister lives 340 miles away) or a hybrid that will do 50+mpg (why don't they do a diesel hybrid??) plus able to tow a 1+ tonne trailer, I'm going to be stuck with an ice vehicle.

Not tight….sensible! Your classics are designed to run on leaded fuel. Ethanol reduces pre ignition, much like lead did. By leaving the ethanol in you are protecting your classic engines.

Thanks for the info' Tim.

It’s not evaporation Gerry. It’s the air and moisture already in the can (and absorbed in the fuel during filling) reacting with the fuel in the can. Every time you open the can the air gets exchanged and away we go again You probably can’t even stop it happening if you store your fuel under vacuum and never use it. I store mine in similar conditions in a sealed plastic petrol can and still get the same issue, hence ditching it at the end of every season.
I‘m not sure how the additives work, but they probably preferentially scavenge the oxygen in the air and moisture out of the fuel solution, minimising the chance of reaction.

Have you seen this Gerry.

HI 570 NO PROBS but is it on utube as this story takes some beleiveing i think this is one of your wind up post ? lol
chris

Seen this movie a few years back your right its a great film, thought i was the only one who seen it lol

 

[simontie]

Hope you got the mower going? we have a few small engines at work and not many people know this but some manufactures have an oil level cut out in there 4 stroke engines so if they run low they won’t run they start and cut out couple of seconds later. Its designed to stop you ruining aperfectly good engine but a real pain if you dont know about it, you have no idea how many people i have complaining about that genny won’t run, check the oil and always low or they have it on a slope…

How old is the fuel in the mower Chris? Unleaded fuel is only good for about six months. After that the ethanol in the fuel absorbs too much moisture from the air to work properly.

What is termed 'the light ends' may evaporate off and the two mentioned causes result in a 'gunk' forming that blocks jets and even fuel lines - much like beer lines that aren't pulled through often enough :disappointed2:! As mentioned, drain fuel tank; using kero clean filters and lines and flush through with a little fresh fuel. Oh, and check for rust particles or discolouration - this has often worked for me in the past mate!

Not sure that’s a particularly good idea Ian. Apart from the obvious safety concerns, ethanol is one of the additives used to reduce pinking in an engine so minimises damage. In addition, modern car injector control systems are designed to work with ethanol mix petrol. E10 produces about ten percent less CO2 per unit volume burned than ethanol free petrol. Removing the ethanol will cause the engine management system to work inefficiently when trying to control emissions, in turn reducing engine power and decreasing engine life.
Seems like the petrol head equivalent of the anti vax movement to me!

I WAs thinking more for use in small engined garden machines most of which are two stroke.

 

[Tim Marlow]

Ah, right. I think modern two stroke oil contains fuel stabilisers anyway. I certainly haven’t had any issues with mixed two stroke going off. Then again, I only mix half a litre at a time for my strimmer/multi tool. The mower has ia four stroke engine.

Have you seen this Gerry.

Will have a proper look at it tomorrow, thanks

Have you seen this Gerry.

That looks a fine chassis!

 

[Airborne01]

Saves wasting money on lawn mowers :tears-of-joy: !

 

[boatman]

YES i love chassis! lol
