What fuel mix ratio best for M-tronic saws

[Jeffbecky1]

I’m new to these computerized carb saws and was wondering what fuel mix ratio best for M-tronic saws

Not sure about "best" but I believe the general consensus is 40:1.


P.S. Please don't ask which oil..

This is a slippery.

I’m going to be running Bel-ray H1-R I’ve heard good things about this oil, I believe Mastermind runs this oil

 

[Duck]

Most Stihl manuals will specify a 50:1 mix, I don't know what "best" is though

 

[Spladle160]

Run whatever you normally run unless you have a problem with it.

That's what I run at 40:1, coats everything nicely and leaves very little carbon behind.

I run 40:1 Echo Powerblend and non-ethanol gasoline in everything. Standard carb saws, M-Tronic saws, string trimmers...

My Mastermind 661 has a 40:1 only sticker on it that was put on there by Randy and he runs yamalube 2r if I'm not mistaken.

I guess he switched

H1R is real thick and doesn’t combust unless loaded like milling lumber. A lot better choices out there especially for mtronic saws like Yamalube, maxima k2, amaoil saber, and so on.

 

[dolmarkid]

Schaffer’s 7000 is good stuff

 

[chipper1]

40:1 maxima k2 for me unless I don't have it, then whatever 40:1.

My saws are not Mtron.

I did today. Too fat down low.

Switched from yesterday's 40-1 to today's 32-1. I'm not running the mill loaded hard enough to keep the low cleaned out doing shorter narrower pieces. I was only cutting 25"-32" walnut logs 11ft long. It likes 40-1 on them apparently. The tune was a pia to find down @ idol. Saw ran great, pulled hard. Four stroked a bit earlier, meh. Going to dump a quart or so in that two gallons of mix and call it good. Idols were better in all my saws @40-1. Summer is just easier to tune in @32-1 imo ymmv. The long bar always gets 32-1 only!

Edit. Pump 88 or 89. 10% Eth

H1R Belray or Hondas best, about the same oil, are good to best out there. I tested lots of it in stuff and saws. Very low wear but like Mike said.....you better get it hot or your muffler will weep goo.

 

[mdavlee]

Hp2 ran clean milling down to 16 or 20:1. I can’t remember which.

 

[Deets066]

Most Stihl manuals will specify a 50:1 mix, I don't know what "best" is though

That’s only if using stihl oil do they specify 50:1. It says if using any other oil to run it at 25:1

 

[Stihl working Hard]

I run 40:1 in my MMWS Mobil 1 2T Racing never an issue clean as a whistle inside next to no carbon at all

 

[Lightning Performance]

You should be able to make an informed decision now.

Let us know how it goes.

32-1 schaeffers in all saws
