Quality of unleaded going down

[Mark Bolam]

Why would you switch Jack?

Just buy E5, or use Aspen.

I would love to use alkylate fuel, but it fecks up old saws faster than prince andrew does a 16 year old !

How do you dispose of the old fuel once mixed for two stroke?

if I have a can of straight petrol that’s been about for awhile I tend to add it to the cars tank when it’s nearly  full anyway

seems ok 

 

 

 

In Landrover, other car has cataylst, which will not go down well. K

Those old diesels drink anything don’t they Khriss!

My mtronic all over the place despite attempts to reset etc .sometimes too fast then too slow or hardly goes at all so load of useless shit .I blame it on changing between motomix and unleaded 

Huh. I've a couple. Switching doesn't seem to bother them at all. I'd say your controller unit is playing up.

I wonder if autotune/m-tronic cope with e10 better?

 

I stand by my old suggestion of mixing Aspen with petrol half and half, to offset the crappyness of the petrol and reduce the cost of the Aspen. Optimum, always shooting for the optimum.

 

 

Stihl say M-tronic machines are good to E25. I can believe this as its standard fuel in Brazil where they have a factory and probably been tested. They even run E100 out there!

Have you been back to UK recently Mick? We’ve got a lot of shit roads as well🤔

On my trips back I have noticed, but not to the same scale and there is infrastructure investment, at least there seems to be looking at some local FB pages I am a member of.

I have two 346xp’s that had run on pump fuel throughout their lives, switched to Aspen about 7-8 years ago, never had any problems whatsoever.

Sadly I have killed 2 saws trying to switch a 346 and a 200t several years ago. In an ideal world I would switch tomorrow

Must admit i've switched back of v power? and onto E10, to early to tell a difference yet.

I thought my 550 was 4 stroking a bit on the 99 octane stuff

 

But i've heard all sorts, to be honest i think no one really has a clue about e5/10 and wot i means for saws.

Semingly in usa petrols been e10 or more for years now and they will be running a lot of saws over there.
