e10

The higher the ethanol, the quicker the petrol will go off into some jelly, horrible stuff....which in turn blocks your carb.

I don't believe you should see any issues running as such....but storage is an issue and next time you go to start the saw, it may not start. I always empty the fuel when I've finished and pull the saw over a few times to empty the carb.

There is a solution, but it isn't cheap. That said, if you are just doing some odd sawing here and there it may help. This stuff: Aspen 2 | Aspen 4 | Premixed Petrol | Aspen Fuel

It is premixed, 0% ethanol so you can leave it as long as you like and you'll have no issues.

Cheers,
Rob
 
had all my kit serviced, the saw is new and only been run on aspen, the guy doing the service said the hedge cutter given to us by the mother in law had gunk in the carb from petrol, stay away from e10 unless using loads. most of the issues he sees now are from e10 in domestic kit. im only going to use aspen as the extra cost is written off against unreliable starting and having to bugger about till they work
 
thats what ive been told ive had problems with e10 so i bought some aspen and not had a problem i think for me who doesnt use a chainsaw every day its worth the extra cost bs

E10 rots your carbs and attracts water. Don't store it on metal cans. Also, I've heard a lot of people say consumption is up and power down.
I haven't touched it. I've been using E5 premium fuel since E10 came out and have had no ill effects at all. All the service mechanics I've spoken to have advised using E5 premium.

If it's only occasional use and your tools spend a lot of time sitting there with fuel in them, use Aspen.
 
I have used both Aspen and the higher grade premium fuel rather than E10 - premium fuel wins on cost but requires oil for 2 strokes - I bought a bottle of Stihl Green stuff and it made everything smoke or start badly Aspen is wonderful but ludicrously pricey so my stuff gets a treat with Aspen now and again. Here it £20 quid for 5 litres - I have no idea where it comes from but Aspen sounds like the USA - transportation costs cant account for the price though.
 
Aspen 4 is (if I am correct) naptha.
I use naptha panel wipe in my coleman stoves and lamps. (It's also the same as Zippo lighter fluid.)

Delete/correct/flame me as appropriate.

Nope, it is not naptha (which is a very broad brush description).

It is an alkylated fuel, chemically created. Not a simple distillation of crude oil.

What is alkylate petrol?

Superb stuff. I use it when doing small jobs with my strimmer, brush cutter and two chain saws. You can leave it in the tank, carburettor etc. indefinitely.

Also used when I lay up my small 4 stroke generator, used in my campervan, after each trip. I.e. syphon out remaining E5 petrol, run carb. dry, Top up with a bit of Aspen, restart, let it run a bit until ordinary petrol all gone. Lay up. Starts first or second pull every time.

I run all these things on super unleaded (E5) usually. But drain that afterwards and flush through with Aspen if not going to use them again for a week or two.

I buy about 5l/year for all of this. Find your stockists at Aspen Alkylate Petrol | Alkylate Fuel | Aspen Fuel I paid about £18 last time. Or you can have it delivered for maybe £30, which doesn't seem unreasonable. BTW the container it comes in is of course legal for storing petrol of whatever sort.

It doesn't seem to work well in Coleman stoves, possibly not volatile enough to get them going quickly, flares up, but eventually does run well when the generator has heated up sufficiently. However it does very well in my Primus backpacking stoves. Panel wipe is horrible poisonous stuff, laced with all sorts of other things, I've tried it in stoves, it does work but I'd only ever use it outdoors, not standing over the stove. I'd rather just use pump petrol. You can tell it's not just a refined naptha like Coleman fuel just from the smell of it, my can mentions from memory toluenes and other things as well. Never mind near or under a tent awning. I'm happy to do that with Aspen.

I use the plain 4T version and mix it in the correct ratio for my 2T machinery. The 2T version is I think 50:1 ratio, which is not correct for my tools.

Aspen is good for filling your law mower up before the winter lay-up.
