Petrol and oil
 

I've got a petrol lawnmower and a petrol hedge trimmer.
Now I'm not telling you that to brag!

Lawnmower likes its petrol straight and hedge trimmer prefers a dash of oil.

Rather than have two cans on the go could I just have one 'petrol plus oil'
can and refuel both machines or do you think it would upset the lawn mower.

This also means that I get a faster turnover of petrol so that it is less
likely to go stale.

When you say "prefers a drop of oil" is one (or both) of these things a
2-stroke? If not, what sort of a drop of oil does it prefer?

Personally, I favour a drop of neck oil.

Hedgecutter is two stroke. Have been using synthetic oil.

Depends on the mix but it will probably oil up the plug of the lawn
mower.

Try it.

I wouldn't put it in the lawn mower unless you like blue smoke.

Buy another can :)

One can for petrol and the other for the correct 2 stroke mix.
Get the mix wrong on 2 stroke and you will shorten the life of the 2 stroke
engine........so make sure yout petrol oil ratio
is right and mix up a whole can full.

As another poster said.....2 stroke mix is not too good for a 4 stroke motor

Go for it !

Just buy one of the 2-stroke oil mixer cans, and keep the 5l container
for the mower.
They are around £4 from garden centres, with scales on the side for
measuring out the 2-stroke oil. Fill it to the level with petrol, then
top it up to the required level with the oil.
Dead easy, and it stops you having to measure out the oil separately.
Of course, you will still have 2 containers, but one will only hold
around 1 litre,so very easy to store, the other will have normal petrol
in it.

And don't leave it half full, or in the cooler weather the water in the air
will condense and eventually settle at the bottom of the petrol. You will
then put it in the lawnmower. Later, when you start the lawnmower, it will
have a carburettor full of water.

Doesn't matter so much with a strimmer cos it's never the same way up for
long.

Another urban legend. If you had stayed awake in A level
physics/chemistry you'd be able to work it out for yourself.

'Tisn't. The water is already in the petrol. They add it at the "factory" to
make the engine run quieter. The exception AFAIK is Avgas, where they try
not to put the water in (and indeed take it out) to minimise deaths on
takeoff.

Well, I never did A level chemistry, but I can assure you that it can
happen, because I have seen it. For it to do so, you need an
alternation between conditions of high absolute humidity and ones
of low temperature, combined with an air gap large enough to form
droplets that run down the side of the container. I have never
seen it happen with anything smaller than a 5 gallon drum, left a
quarter full for several decades.

Since I stopped buying fuel in boatyards 10 years ago, I have had
zero water in my boat's fuel, even when one winter I left the tank
half full.

What gums up two stroke engines left unused during the winter is that
the petrol in the carburetor evaporates leaving behind the oil. You
should turn of the fuel and run the engine until it stops before
putting it away for winter.

Here's something to read
http://www.yachtsurvey.com/myth_of_c...fuel_tanks.htm

I don't rely on stuff on the internet cos most of it is balls. So is most of
what I write, but this particular one isn't.

Having flown several light aircraft, I have on many occasions removed water
from them during preflight checks. It is done by shoving a pointy thing up a
valve underneath the wing tank and waiting until the stuff that comes out
doesn't have tell-tale bubbles or globules of water in.

It is not mythical water, it is real wet water.

Planes tend to stay the same way up, as far as gravity is concerned (even
though they tilt in order to turn). So do lawnmowers.

Cars don't have the same problem because they go round corners and that
swills the fuel about. Like strimmers. Also cars tend now to be injected,
and injectors can cope with a dash of H2O. Carburettors can't when the float
is full of the stuff.

Oh well another genius idea bites the dust!
Two cans it is.

Thanks for the feedback guys.
