What oil is best? and what ratio?

[cus_deluxe]

Anyone remember when Julian said his 661 cut faster on a 50:1 ratio over 32:1....

Then he proved it with a video...

variables....duh.

Rich or lean is referring to the fuel/air ratio. Nothing to do with the oil. If you add more oil you are taking up the space that would have been gas, so therefore you have less gas and the same amount of air, so therefore it creates a leaner fuel/air ratio. Make sense?

No. Because if I add more oil. I turn my screw out to add more mix into the combustion chamber. Therefor still not running lean.

Another point. My saws are old. I’m not outta the game so to speak but I have every size saw I’ll ever “need”.

my 2 series saws have two different manuals. One for US one for everywhere else. I believe they recommend 32:1 in the same saw if not sold in us.

pretty confident they use the same carb regardless so you must be able to adjust for a bit more oil in the fuel mix.

I don't really know the variables...

It was an m-tronic 661...no tuning allowed...

We are pole vaulting over mouse turds here. A 20 degree change in temp will have more effect than a 1.2% change in oil ratio, which is the difference between 32:1 and 50:1

Julian methods are not scientific.
Others have done scientific tests and all of them contradict his results.

For starters your assuming Mtronic controls very finely. It doesn't.
FWIW one would need a dyno to do such a test and one that included instrumentation for fuel flow and exhaust composition.
Regardless running more oil for me isn't about making a small amount of extra HP. It's about protecting your bearings and pistons from extreme conditions.

Correct.

How big is the pile of mouse turds and how long is your vaulting pole? You have to have the correct lift to distance ratio. I'm not a pole vaulter so I will just let you carry on with this. I just like pie and stuff.

I didn't assume anything.

Julian's tests were unbiased and as "real world" as you could get.

 

[junkman]

Tests on snowmobiles and dirt bikes do not work for data for saws and weed eaters ,put 32 to 1 in your weed eater then 50 to 1 ,and you will see what I mean when you try to tune it.
These little engines more oil loses power like the 661 test showed,if you want to run a blubbering tool run more oil than it needs.

How bout weed eater vs large saw? Considering large saw is fairly bigger

But it wasn't science

It was in the real world, doesn't count.

Not to mention at bare minimum most of these guys are running a saw with a muffler mod, as well as a razor sharp chain..Less heat = less oil burned.

I still think it's funny that people think you need to run a motorcycle oil at 32:1 for your chainsaw to last

These guys make up sh!t to worry about

Some of my ported m-tronic saws still puke oil at 50:1 with boutique oil when not under a heavy load...I've even seen them do it with Red Armor.

Oh..and a good amount of that time they weren't running a razor sharp chain..another one of those real world things..
