When you find out, B&Q, and others no doubt, sell a calibrated plastic bottle to make up the various mixes.

The bottle of oil I have has a cap which contains the right amount for 1 gallon of petrol.

I have a Stihl strimmer and the mix is 25:1 although it can be anywhere in the range 20:1 to 30:1 depending on how much smoke you want to make!

Don't quote me but I think they run in when new on a 50:1 mix for a specific time, then use 25:1.

Forgot to say - a US gallon is equivalent to approx 3/4 of an imperial gallon.

For one litre of petrol you should put in 20 mls for a 50:1 mix as ON says for new kit and 40mls for a 25:1 mix when it's run in

Hope this helps.

Saw my mate last night in the pub who worked for a hire firm and said 20mls to 1 litre of fuel. Spot on there Soft Top.!!

It's not been left in the shed drained of fuel and in the cellar as garden sheds get unwanted visitors at the moment according to the local paper.

You need to RTFM for the specific tool.

I have a chainsaw and a hedgetrimmer that want 40:1, and a Ryobi brush cutter that wants 20:1.

Isn't it a pain lugging a generator around the woods?

Always been intrigued by the number of people who buy chainsaws. Have you all got acres of timber to fell? What do you use them for? Have never fancied one myself - too dangerous. Have always managed with a decent bow saw, even when I had a wood burning stove. Certainly don't need one in a suburban garden to prune a few shrubs.

I'm sure you're right CGN. Dangerous things. Even for health and safety officers it seems.

But if you insist on using one keep a bag of frozen pastry handy.

Of course the great advantage of a bowsaw is you get nice and warm cutting the wood, so you don't need to burn so much.

A bow-saw is surprisingly quick and efficient. Secret is to change blades regularly

And what possessed anyone, let alone someone trained in safety, to stand directly below a running chainsaw? My children know not to stand below me if I'm holding so much as a screwdriver.

I wonder what a chainsaw costs, compared with 20 years ago. Is an unfortunate consequence of cheap power tools and expensive labour that people are now tempted to try jobs themselves that would be better left to an expert?

Still, whatever question the report leaves unanswered, at least it tells us the value of their house.

They're useful if you have a mature hedge that needs reducing and the hedgecutter can't cope, but you can get away with an electric one. Other than living in the woods and running a charcoal burning facility, you shouldn't need one, unless it's for self defence.

All Stihl saws are 50:1. But make sure you use the red stihl oil. They also sell a nice fuel can that holds both chain oil and petrol, and also has a formula 1 type fillers so you just push the spout in and it stops when full.

Yup, it gets used for that. We have quite a few trees as well though I dare say we could use a bow saw. Hard work for chopping up for the fire though.

I do agree they are lethal and require the greatest care, eye, bonce and foot protection at a minimum. And no-one else anywhere near.

I had a pal (sadly now not with us, a different kind of accident) who 'did' trees. He had some serious chain saws, frequently swinging from his belt while he climbed big trees and used one handed. I couldn't bear to watch him.

As others have said, the mix may vary for different machines. It's a nuisance if you have several different ones, having to keep separate labelled cans. My Seagull outboard uses 10:1.

I did have a petrol chainsaw once, but found it more of a nuisance for cutting logs because of the need to keep putting it down to lift a new log onto the saw-horse. I don't like having a running chain saw wandering its way around on the ground. I now use an electric chainsaw, which is good on anything up to 6" and of course has easy on/off.

When rarely I need to cut a bigger tree I either run several long extensions up the wood or else fell it with a bow saw and then drag closer to the electricity supply for chopping up.
