What oil is best? and what ratio?

[huskihl]

Walmart synthetic was proven to be good oil here.

I believe it was middle of the pack, which is pretty good. Definitely better than several more expensive oils

It’s great stuff. I’ve had zero issues at 32:1 on any saw.

32:1 even on 40-50cc saws? Think saber same ratio would be the same? Only asking cause I thought I remember some smaller mtronic/autotune saws having issues with too rich of a ratio. But I’m assuming it depends on the viscosity of the mix oil.

Dominator’s base viscosity eliminates this as an issue. The single biggest thing I have learned about oil from others testing is higher viscosity is used to make up for deficiencies in add pack. That comes with a price usually in carbon deposits or spooge. Many think Dominator isn’t a good oil due to lack of excess oil in the crankcase. That’s by design, rolling element bearings can be over lubricated which hurts performance.

The smaller the ccs....the faster it spins...

What is CCS?

 

[davidwyby]

What is CCS?

Cubic centimeters

Engine size

Yes. I haven’t had any issues with Dominator. My initial problems were with Motul 800. I swapped oils to saber at that time and the problem went away. Now, I drill the jets most MT saws that I port, so I changed a bunch of variables. I prefer the safety of 32:1 in my saws.

So, on a semi related note, what do you do to preserve the fuel system of a saw or other two stroke that is only used sporadically? I love my saws but don't get to run them as much as I would. So they can go for weeks at a time without being used. What I have always done is, when I mix up a new can of fuel, dump out the old fuel in the saws to burn in my four strokes. Then I fill each one up about half way and run it for a few minutes to circulate the new fuel. This is what works for me at least, of course I always use fuel stabilizer.

Can you buy ethanol free fuel? I have had zero issues using E Free 90 even after extended lay up.

 

[FergusonTO35]

Closest place I know of is out of the way, but I admittedly haven't looked very hard. Will seek it out when its time to mix up some more fuel.

 

[davidwyby]

In a humid climate, completely full with e free so there is no air for condensation. I think @Benwa had saws in WA for 3 years that way and they were fine.

In a hot climate…I keep mine in the A/C….under 80°f, the temp at which gas vaporizes. E free. No more problems. 3120 probably only comes out a couple few times a year.

 

[davidwyby]

Before I had AC and e free pump gas I would store them with bottled premix.

 

[thedude74]

Ethanol is one thing I'm quite happy about being to expensive to ship up here.

 

[mrxlh]

I use stabilizer and a fuel system cleaner every time I mix up fuel. I don’t use saws as often as I would like either. I have no issues with any of mine following this regimen.

Sadly many folks see the "Made in USA" or "American made" label and falsely believe it. I challenge anyone to take a look at this century as @Lions fan referenced and find a piece of equipment, designed, manufactured, and built in America with parts that were designed, manufactured, and built in America.

The label is irrelevant.

Very true I can't remember exactly because they keep lowering it but last time I looked I believe to put Made in the USA only %45 of the components needed to be US made.

I truly do not know what it takes to be classified as "Made in America" but I have yet to find anyone who has come up with something that truly is made here this century hell since 1945 in many cases (NOT ALL)

 

[Powerstroke Cowboy]

All the gas for my small engines is ethanol free and treated with Sea Foam. It works good for me

 

[Bill G]

I am a huge proponent of ethanol and I think we need to use a helluva lot more of it including E85 but I do not use it in saws. I know there are areas of the country that cannot get ethanol free fuel. As much as I love ethanol I believe folks need to have other options and it should not be forced down folks throats. The same for biodiesel. I live in the heart of corn country and we can easily get ethanol free fuel here.

 

[FergusonTO35]

Ethanol is actually a very good motor fuel, the engine components and fuel metering need to be set up properly for it. Isn't straight ethanol like 140 octane or something crazy like that? I think switching fuels to renewable sources will help keep internal combustion engines viable instead of us being force fed battery everything.

 

[Bill G]

They run Indy cars on ethanol but if course it is a bit different blend
