Regular or Premium Petrol

[openspaceman]

I am glad you understand, I am not sure I do!

 

Surrey is a long way from here for collection! But if you want to collect then the price breaks are the same as for delivered.

 

I offer 1-8 cans at RRP (£18.98 for 5litres) (Delivery @ £24.00 inc vat, minimum 3 cans)

9-53 cans at 5% discount ( delivery £24.00 inc vat)

54 cans at 10% discount plus free delivery.

 

These are our prices, other dealers may differ.

 

OK I'll see if my brother will pick some up for me.

And way better for the machine .

 

How? As Mark Bolam said earlier.

I've got quite a few 2 strokes well over 10 years old running great on supermarket fuel, If my machines were blowing up on a regular basis I'd think differently.

I think we need to take a step back and identify what is wrong with pump fuel. Its a big subject that has been covered in depth on various threads, but I bullet a few points here.

• Pump petrol contains around 35% aromatics. They do not combust fully and deposit soot in the upper cylinder and exhaust . This leads to a slow increase in compression and decrease in gas flow. But the process is slow and fresh fuel leaves less than stale fuel. Aromatics are also aggressive to elastomers such as fuel lines, diaphragms and tanks. Once again a slow process and better with fresh fuel

• Petrol also contains Olefins which react with fuel lines as well as forming gums, again fresh fuel is not as bad as stale fuel.
  

• Petrol contains Oxygenates such as ethanol which lean out the mixture creating high temperatures and possible engine damage.
  

• Stale fuel rejects the 2 stroke oil which was nicely dissolved in the fresh fuel. Engines run on this will suffer from advanced wear and even catastrophic failure. Again, fresh fuel ain' too bad.
  

 

 

So basically, even though petrol is sort of OK, and has been the normal fuel ever since these engines were invented, it does have its problems.

 

Good fuel management, as many Arbtalkers will have, will reduce these problems to an acceptable level and good engine life will be achieved.

Many less informed operators have very poor fuel management and will suffer problems. We see these problems all the time.

 

Alkylate fuels contain no Aromatics, no Olefins and no Oxygenates which result in a very pure fuel which without will extend engine life considerably, but at a price.

 

As many of you point out, the savings using pump petrol will pay for more frequent machine replacement, and that's a fair point with which I sort of agree.

 

But there is no doubt that engines run better, more consistently, and last longer when burning Alkylate, and that is only part of the story.

 

Its also better for your health and you cannot really put a price on that.

For me, it's more about my health than machine life. I know it's only anecdotal but I feel much better at the end of a day running on Aspen than pump fuel. I was, and still am, highly critical of the price of Aspen but I grit my teeth and pay it for the sake of not feeling shi'ite at the end of a day cutting.

[Mick Dempsey]

I don't feel bad at the end of a day's cutting.

It's a personal thing, I guess. After a day using pump fuel, I used to have a headache and my breathing felt like I was having to work harder to physically pull the air in. I don't feel like that since I started using Aspen. I don't doubt others feel different.

[Mick Dempsey]

Fair enough, maybe you should talk about this breathlessness with a doctor, get some tests. My old man suffered from that, ended up diagnosed with heart problems.

Not looking to further the argument Felix, it's a genuine suggestion.

Taken in the sentiment it was expressed, Mick . If it was an ongoing condition then I would, without doubt, but sinced I changed fuels I feel fine.

If you strip down a saw that's run on pump fuel for a given time and one thats run on Aspen fom the get go for the same length of time the difference is apparent . I have seen the pictures and have no reason to think they are faked .

Is this what the new(ish) Stihl green fuel lines address or at least help with?
