    When I got my 365 I bought some as it says 50:1 on xp, 30:1 anything else.  I already had stihl green though and that's why I dug around.  Stihl quote some tougher/better tests/specs for the green, husky don't for the blue.  So I suspect green is as good or marginally better.  Being the cautious type I mix half and half (turquoise? Sea green?) at 40:1!

     

    Any how, good news re synergy fuels, seems I have plenty of Esso around too now I look them up.  I do hope shell follow suit though, they used to guarantee ethenol free vpower, until a couple of years ago 

    I usually mix between 40:1 and 50:1 anyway, I'd prefer a little excess oil than too little, my saw runs fast since the 54mm upgrade, and retrofitting the heated handles, and being sat unused more than used a lot of the time, so didn't want to take any chances.

    I used to use Shell V-Power, then stopped, for the above reasons, I use the Esso +99 in my strimmer.
     

    The Aspen4 5 litre cartons are great, plenty of headroom to tip oil in and mix without overflowing.

    Out of interest, husky xp, that's the blue stuff right?  Why that? I know it's there better oil but why not stihl green for example?  I have both and can find the specs for green, blue though I could only find it met the basic tests and then husky were vague about it being better!

    Just preference really, I've always used husky oil, odd really now I come to think of it, started using it 10 years or so ago, or whatever the husky equivalent was back then, their 1 litre measuring cartons have a graduated gauge on the side, so it will measure for 1L, 2L, 3L, etc, of petrol, so you don't have to use a whole 5L, I think someone recommended it over Stihl's oils originally, so I've just stuck with it, the only variable then is the fuel.

  3. One thing to be wary of is that in dry, anhydrous conditions, and hot environments, ethanol can react with both aluminium and magnesium, aluminium being the bulk component of most chainsaw cylinders, and/or pistons, the Stihl MS400 C-M has a magnesium alloy piston.

    Considering fresh E5, or E10, is dry, water free, and if a saw by it's nature, gets hot whilst running, the remaining fuel under the piston will have opportunity to react with both the lower sections of the piston and cylinder, and will evaporate into the upper chamber when the saw stops running, subsequently working it's way around the sides of the piston and into the piston ring grooves. Yes, a lot are Nikasil coated, however, all it takes is a worn surface, or not plated exposed area to come into contact for the corrosion to start.
     

    It leaves a white powdery residue on the surface, also making the aluminium surface rough and porous...
    Additionally, as others have said, it sucks moisture out of the air like a vacuum, and we all know what water in a cylinder will do. Whilst it won't form aluminium or magnesium ethoxide, the reaction product of ethanol and either metal, in wet environments, it will leave a residue of the metal oxide or hydroxide.

     

    Just my 2p, just resurrected my MS460(W) 54mm , doesn't get used heavily, and had been left for a while, but only putting Aspen4 mixed with Husqvarna XP 2 stroke oil in it from now on, I can justify the cost because of the limited/irregular use.

    Esso offer a "potentially" E0 fuel, Esso Synergy Supreme+ 99, which whilst they claim it to be ethanol free, it has to be labelled E5 because of government regulations saying fuels must be labelled in accordance with containing "up to" 5% ethanol, not that they contain a total of 5%:

    Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps.

     

    There’s currently no requirement for renewable fuel, like ethanol, to be present in super unleaded petrol although this could change in the future, in which case we would comply with any new legislation.

  4. As Spud said, take the clutch off then the pump should be held in with two T27 screws...

     

    It's a good idea to take all the plastic covers around the clutch off too for better access to removing the brake band...

    If it's anything like an MS460 it's a doddle, done in 20mins or less :D

     

    It's also a good idea to pull the oil hose out the same side as the pump and check it's in good condition/clean, and blow through the outward feed through the crank case to clear any gunge...

  5. Well it's been some time since I started these off but glad to say the Pearl oysters have sprouted!!!!!

     

    I haven't been near the house since towards the end of last year whilst it's been refurbished, but took a peek outside and the Pearl oysters were sprouting out of all sides of the log, I picked a few, sadly didn't have my phone with me at the time but all looking good...

     

    Here's a couple of pics of what I brought back:

    They're on average about the size of a 20 box of cigarettes/fags...

     

    And just as thick, seem quite meaty and the gills are well formed, placed them gill side down on the draining board for about 5 minutes and it was covered in spores...

  6. ok sorry i meant charcoal, :blushing: .......

     

    this guy is on about making charcoal from things other than wood, he has made a massive prototype using a shipping container and some whirlygigs and a spoon.... or something like that, but the thing got too hot and it all went wrong, he asked me to come on here and ask the pro's for some advice, he is a mad scientist who isnt afraid of experimenting so could be fun for someone if they are interested.

     

    .......

     

     

    I wouldn't mind meeting this guy to have a chat :thumbup1:

     

    Bit of a "maddun" myself :lol:, I do a bit of welding on the side and was considering building a set of kilns myself that were self heating once the wood gas had been ignited after preheating...

    I was going to construct the kilns out of large diameter steel pipe and construct a fire brick/refractory surround around the outside, with a hinged/sliding door made of cast refractory/fire bricks...

     

    The only difficulty was constructing the chimney, high enough and conspicuous enough to create enough draw...

     

    I was then going to use CO2 to vent the kilns whilst cooling to limit the char...

  7. Has the carb been adjusted recently?

     

    Could be not enough fuel going to the saw on the idle setting?

     

    With the saw off, rotate the cylinder to near the top to shut of the exhaust port and put about 15ml of 2-stroke oil in the cylinder through the exhaust port...

    Rotate the cylinder quickly to the bottom tilting the saw back and to the side slightly, then pull it over a few times gently whilst still off...

    Put 5ml or so of fuel in the cylinder and then try starting it as if from cold...

     

     

    I had to do it recently on an old saw that was doing pretty much the same thing, smoked quite a biit on first start then ran fine...

  8.  

     

    So, why are we one of the most heavily taxed countries in the world? Fuel wise! Won't be long til they tax timber as a fuel!

     

     

    Because we owe so much debt to Europe in terms of borrowing and have no means other than tax to pay it back through lack of production and all manufacturing being outsourced...

     

    Add to that we're funding our own unemployed and "dolers" so the bill is enormous...

    If we didn't have so many people that "couldn't be bothered" on the system it would be an easy life over here...

     

    I don't wish this discussion to become more political than it already has but....

     

    It makes my blood boil!!!!!

  9. Diesel can contain upto 5% water, if agitated/QUOTE]

     

    But you dont buy it agitated, you buy it from still underground tanks where all the water settles to the bottom and the feed line is positioned away from the bottom of the tank.

     

    But by the time it's consumed it doesn't have time to settle...

     

    A 5% mix would take weeks to begin to separate, even then there's a very high probability it wouldn't even have started to separate...

     

     

    Again bringing the attention to the government isn't going to do anything, it's a major source of their income and as oil sources are being depleted rapidly, North sea reserves at an all time low as well as Saudi Arabia and Kuwait, there's nothing we can do other than to find a way of not having to buy it on a general public scale...

     

     

    We can't, so they've got us by the short and curlies...

     

     

    Tax! Although the price of oil is fluctuating (:confused1:), why is it the uk has to be adding so much tax to fuel prices? Fair enough that oil costs more then less then more, there's good reason. But the government needs to appreciate small firms can be crippled by fuel costs, as is everyone! How much would the economy boom if duty was lifted? How many of us would say great, i've got x amount extra, i'll invest, save, have a new conservatory, car, tree sorted.......???

     

     

    Then the government has no income, then other services like police, fire and nhs start to suffer...

     

     

    There's a bill going through at the minute for CO2 tokens, you get allocated so many per year per adult...

    If you use them up you have to buy more to buy fuel, if you don't use them up you can cash them in...
