Petrol driven equipment and the new E10 fuel
Col3 Posts: 3
As you may or may not be aware from September we we have to start using the new E10 fuel. This fuel has a higher ethanol content and as a result is known to cause engine damage to vehicles. Other than parts of Scotland the existing E5 fuel is going to be limited to a few filling stations. As many of use petrol driven tools I use a tiller on my allotment does anyone have any information as to what needs to be done to prevent damage to the equipment. I have emailed Mantis with this question and am waiting for a reply. Do we for example have to buy an additive to prevent damage.
I'm going to check with My Man who fixes my stuff
Had a recent email from the engineer who services my Honda lawnmower. He is concerned about the new fuel directives and his advice is to buy the E5 whenever you can find it.
If you have to use E10 he thinks the only way to minimise problems is to not leave fuel in any machines which will be unused for more than 2 - 3 weeks. If the fuel is left in the machines it will probably cause corrosion / perishing of parts. Removing the fuel means either syphoning it off or burning it off (that's good for the environment isn't it?).
During the summer there shouldn't be too much of a problem with the lawnmower - but I'm going to have to remember once we get into autumn.
If I can find it I'll post a copy of his advice.
His advise is that the problem is down to the hydroscopic properties of the increased ethanol content in the E10 fuel. Water in fuel can cause corrosion of parts and will increase the risk of bio-organisms growing in the fuel.
He thinks 2-stroke engines will be ok due to the oil but that 4 stroke engines need to be treated as above.
Personally, I shall be using premium E5 fuel if I can get it and (come autumn) I'll not be filling the lawnmower to the top as I do in summer - putting just enough in to do the job. From November to March I'll probably use Aspen (no ethanol) if I really need to use the lawnmower (I use it for hoovering and chopping up as well as cutting grass).
