aspen fuel

[fergusonforestry]

hi guys just wondering if anyones had any experiance with aspen fuel we have been using it for a few weeks now and have been noticing the seals on the fuel caps have been leaking all over the place and the barrel pump has become stiff and squeeky, anyone else had this?

ive been using aspen for 9 months and touch wood no problems.

Yes mate, normal petrol softens any thing rubber,carbs seals ect aspen has not got the additives that cause this so unless you run it from new you will have these problems in my experience any way that's what I have found... Great stuff apart from that.

Is it a Husqvarna chainsaw? Are the seals black or clear?

Matty has hit the nail on the head with this one.

 

The additive he is referring to is solvents, up to 35% in normal fuel (0% in Aspen). Solvents is the reason why normal petrol stinks, makes your eyes sore and gives you a headache.

 

The problems you are experiencing are still quite rare and only seem to happen to a few types of saws (varying quality in seals etc). if you replace the seals which are causing you problems and keep using Aspen then this problem wont arise again.

Hi Axel,

Am I likely to experience any problems swapping my 1999 vintage Husqvarna 254xp on Aspen?

[Aspen@AAOIL]

usually older saws like yours dont tend to suffer from problems described originally in this thread.

 

however i do recommend that you dont wear your best shirt for the first few tanks as you will probably find that the initial emissions will be quite dirty considering that Aspen will be cleaning out over 10 years worth of carbon deposits from regular fuel!

 

After this you should be left with a machine which performs better than the day you brought it

I did mention which model of chainsaw and seal type was being used as there is a know problem regardless of fuel types which I have taken up with Husqvarna service. (Companies are careful to admit issues these times)

 

Some might remember a tree surgeon several years ago that was using a Stihl chainsaw which had a fuel leak problem onto his protective trousers which then caught fire and melted onto his legs.:thumbdown:

 

Main issue is thickness of seals from new before being in contact with fuel and the standard of plastic screw threads. This applies to all makes of saws.

 

Who checks when using a saw if the fuel area is damp and slightly leaking?
