New Chainsaws

What's the price comparison running Aspen V normal 2 stroke? Obviously you don't spend money on oil. Is it worth it?

[Ian C]

No they reccoment 50/1 as they have too as dealers but run all there stuff on 25/1. i would rather have the stink than blown saws though. get in a nice conifer and let 1 go after a good strong curry the night before ya can't tell any way!

[skyhuck]

also you never quite get every last drop of oil out in to the can so your probably running 52/1.

 

run 25/1 stihl and no problems now.

 

You should allow for that, I put the 5L mesture into 4.5L!!!

 

25/1 bet your dealer loves you, buying twice as much oil!!

Iv run racing karts and motox bikes so have done the oil thing quite a lot !I think stihl state 50:1 as a minimum requirement , iv seized a saw on 50:1 .does anyone now of a seizure at 25:1

Can also depend a lot on the state of tune of the particular engine Rich, lean, aircooled, water cooled.

[treesnake]

quite right dean im assuming all engines are well serviced and running fine .

Just re built on 084 with a blown engine, got it for a song from last owner as a non runner, honed the pot, new piston and rings and she's a belter. he ran it on 50:1 i think it might be something to do with them being older saws and needing that bit more oil.

properly mixed 50:1 (using good quality semi-synthetic/synthetic 2stroke oil, and good clean high octane fuel) will run any correctly tuned 2-stroke engine perfectly to its peak performance... even older/asian equipment recommended to be run on 32/25:1

 

 

the key thing is to use quality mix oil, quality fuel from a garage you trust (not from a supermarket garage), and most importantly tune the saw correctly! get a tachometer, check your rpms regularly, you might need to re-tune for different qualitys of fuel, altitude changes, length of bar etc...

 

 

dont run 25:1... you're just asking for excessive carbon buildup, and poorer performance... maybe if you use regular motor oil instead of 2-stroke (which is why 20-30 years ago saws were recommended at 25:1... no dedicated 2-stoke oil)

 

cheap insurance is running 40:1 mix, or just tuning a bit rich. but so is a tachometer to check your tuning

 

its easy to toast a piston and cylinder.... but its also easy not to....

Makita recommend if running high quality Makita syntetic oil a mix of 50:1 if using a lower quality or not Makita branded they recommend 40:1 if the petrol has an Octane rating of less than 95 they recommend 25:1. I run on 40:1 with my Makita. No problems yet but its only 2 months old.

really, i run my 084 on aspen which is premixed at 50:1 with no problems, I think its more to do with how well the saw is set up and operated.

 

I really dont buy into this I can tune it by ear rubbish, if your saw needs setting up right, get it put on a tacho or take it to your dealers to do,

 

an extra 1000rpm when your running it for long periods of time isnt going to do it any favours especially if your on 50:1...if you dont set saws up properly or have them serviced regularly then 25:1 is probably the safe way to go as it builds in a safety margin.
