2 stroke shelf life?

[GardenKit]

I have stale fuel in my stilh. I won't be using it for a few months at least. Should I run it dry? I will probably use aspen in future. Thanks

If you have stale fuel now, then you may already have problems which need fixing, either now or in the future.

 

The best bet initially is to drain it, the put fresh mix in and run the saw. This will flush out the stale fuel and the solvents present in fresh fuel may dissolve gum from the stale fuel.

 

This might just save the saw.

 

Then you could run it dry, but the trouble with that is that the rubber parts could dry out and crack.

 

Best, in my opinion to put Aspen in (after the fresh petrol) and run it through, then store it wet with the Aspen

3-5 years, according to Aspen Common questions and answers - en.aspen.se

 

Or if Aspen is stored in a metal container over 10 years!!!

 

3-5 years in a machine or the plastic contains it comes in.

 

It makes no difference if Aspen has been opened, just put the lid back on as per normal.

 

Please pm me or email [email protected] Tel 07568 108953 for more information.

Have a cheap saw i use old fuel in.

The saw is a mccullogh cs34, fuel will be 1,5years old by now.

It was quality fuel and oil from my race boat, fuel smells fresh.

No deposits in contianer...

Always stored in cold place out of sunlight.

Saw works perfect with the fuel.

Hi Mobil1,

 

Sounds like you had very good fuel to start with.

Not sure if fuel you buy today will keep for one and half years and still work!

 

So much has changed with pump fuel and this is still going on with more and more Ethanol being introduced.

 

There is even a penalty tax if fuel does not have a Bio content!!!

 

Kind regards

Maybe, it was no race fuel either.

V-power from shell it is.

Even used a couple of tanks in my new 365 special without problems.

But if i still have some fuel left after this winter it is going in the mower.

2,5 years (winter2015) will be pushing it i think.

Time for some fresh gas then

That is/was good fuel, but your chancing your arm running that through a modern saw, might run fine, but if you persist with using old fuel, it will wreck your saws piston & pot.

 

It's not worth the risk imo.

[onyx landscaping/fencing]

you cant use your saws much if you have had the same fuel for the past 1.5-2 years

[Mobil1]

It was leftover from my boat, about 30l.

Fresh gas with fully synthetic mobil 1 racing oil.

Indeed do not use the saws that much, mainly during winter for tree felling.

Have a woodburner...

To go thru 30l you have to cut alot.

Still +- 10l left , with 2 big trees to go if the guy gives me a call.

I regular check the saws and they have no signs of premature wear, good spvarkplug color and certainly no signs of detonation.

I work as mechanic on combustion engines, racing and commercial use.

I know the risks, and wont use the fuel any further as soon its giving me indications to do so.

If its not to late by then .

Gas is cheaper then the parts i will need to buy to repair the saw, but i still trust the fuel.
