What oil is best? and what ratio?

[Greenerpastures]

This conversation is all because I can not
get Red Armor for my saw in this country.
And as a result I now have to try out what is
available and try to narrow down what one oil
will best suit all my saws, altering only the ratio,
the tune is natural part so can't say it is an extra
step.
Come Monday, the journey begins.

Regards to all, john

I've not found an oil yet that doesn't carbon when tuned crisp. Real rich they'll clean the crown.

And that same low flash point gives more opportunity to burn the oil in the mix
and off the cylinder and piston, I would say not good as some oil needs to remain,
so tell me how to keep a film on the innards, higher flash point is how, but not
crazy high or you will end up with too much oil to create carbon build up.

You could put less of the higher flash point oil in, and thats what amsoil do,
amongst other things, the shear strength of the amsoil is also very high and thus
great protection.
50:1 amsoil keeps things oiled because it sticks around.

A two-stroke engine actually has two very different kinds of lubrication needs.
The lower end crank and rod bearings prefer a slow drip of a very heavy viscosity oil,
while the top end parts wear best with a deluge of a very lightweight oil.
Since these are two very opposite lubrication needs, you have to choose whom you want to pleaase.
You can buy cranks and crank bearings that will all offer similar performance, but everyone
wants to do whatever can be done to preserve a good running piston / cylinder set.
Given all this, heavier premixes of lighter viscosity oils are more desirable to most.

Does anyone actually run amsoil saber in samll saws, it seems like massive over kill
to do so.

At no point did anything you just said make any sense or is factually true. You think the way you do because you do not understand the nature of two cycle oils being a blend of components and you do not know what flash point measures and what it doesn't.

You wont.. four strokes still have carbon on the piston crown and they don' burn pre mix.

What I posted much earlier shows, there is a direct link between the flashpoint of oils and what purpose the oils are best suited to.
How about we put in an oil that does not burn at all, just spit it out the exhaust port,
or one that has such a low flash point in goes off before the fuel, (have a look), all the
recent low smoke low ash oils show this clearly, echo powerblend in particular.
Viscosity of oil and Shear strength are also to be noted, because you need to ensure flow and still mentain shear protection, fact, armour 50:1 demonstrates this clearly.
We all know two stroke oils are a blend, fact, read the ingredients in the oils.
We all know that so far the oil blends of our choice
is added to the fuel in our chainsaws, fact, ask anyone.

Agreed, but is there any other effects from running
enough on the rich side, am only asking as I have not suffered any in my time, I only cut firewood, do some thinning,
keep hedges under control, and sort out anyone who needs a tree removed, or branced, so not a full time guy by any means.
We have a 40 yr old Stihl 041AV here, and she was ran rich enough to keep her clean, we never had her opened so am wondering if this is the way to go.
This old saw got every concoction of oil under the sun, so oil alone can not be contrubuted to here long life, so tune must have had a large part to play in it.

Thanks & Regards, john

In my thinking about what Ben said would be flashpoint alone wont determine combustion characteristics because there are other components in the blend that will either impede or enhance combustion also? Just thoughts on my end

Tuni h that rich they'll usually live a long happy life

I think he said any of what I wrote made no sence.
But I agree with what you say regarding flashpoint
playing a minor role in combustion, it only begins
to matter when we want to ensure the oils burn well enough to comply with the EPA in regard to keeping down emissions, and I would presume this is responsible for the trend in the more recent oils having lower flash points.
Im not dwelling on flashpoints, but interested in how a lower flash point effects the oil regarding engine lubrication, but am sure the manufacturers have done ther testing and addressed this too.
I suppose in time, these new oils will have made a name for themselves, through our usage, discussions and documentation others will
be more certain of what works and what does not bode well, and its all about what works.
If I had all 50cc saws, then any brand name would be fine, but there is a huge
difference in the forces at play between 50cc and 79cc.

Thanks Keith !
Just grabbed 3 gallons !
They’re better than 50% off

I didn't know you ran Red Armor oil Kevin.
You run it at 32:1?

Thats expensive as hell i can get 2 gal.of amsoil saber for that

Wow...

I paid 57 bucks for a gallon of red armor at Labuda farm service about 20 minutes from me.

Expensive right

Less quality oil

 

[Cracker Boy]

Less quality oil

If you say so.no oil is worth that much money imo thats crazy

 

[sawmikaze]

You gotta be half corked to pay over 100 bucks a gallon for oil in your chainsaw.

 

[sawmikaze]

It isn't that much of a less....

17.50 qt isnt bad IMO. Ive used plenty of Amsoil and inspected internally. It wasnt bad at all but not impressive either
