What oil is best? and what ratio?

[Keith Gandy]

The pic just looks like piston varnish you get from running synthetic oil. Its not desirable but hardly surprising either.

Why doesnt all synthetic oils do that?

It reminds me of what BelRay H1R does

Ok I ran 4 tanks red armor last night. Use the same setup max flow, 28" 404, BP 91 eth free gas etc etc.

So this stuff is really RED. It's like pouring red kool-aid into the gas tank. 32:1 seems to be a touch too much. I think if I run it again I'll try 36 or40:1. (this is non ported 661).

It appears the Red armor started to clean things up. But considering how big of a mess the Super Techniplate left. I'd say it did ok for 4 tanks. Here is the post on super techniplate - http://opeforum.com/threads/what-oil-is-best-and-what-ratio.98/page-353#post-153127

Piston Exhaust side - very very thin coat. But was shut down right after the cut.
Piston intake side - good coat
crank - good coat

Conclusion - Seems like decent stuff. I'd like to try it with 36:1 or 40:1 and starting out with a clean P/C to see what it leaves behind if anything.

So next up to bat - will go with the old reliable. Schaeffers and see if that can clean this super techniplate mess up.

looks like it's starting to clean up the mess klotz super techniplate left on the pistion.

Is it even burning the oil?

Synthetics don't leave varnish like that in my expiereance.
Castor does.

It looks like alota oil because of the dye but yea it looks like its not combusting well. Kinda reminds me of Motul 800t

optical illusion ie. the dye. I would say it's a tad too much. and I think changing to 36:1 maybee 40:1 would do the trick.

Stuff sure is RED!!! lol

I think so too but finding an oil that performs at 32to1 well would be greatest benefit for most that use a saw for general firewood cutting or similar loads. Milling would be a different scenario IMO. Been alota oils tested that leave good residual but combust well also at 32to1

 

[Keith Gandy]

That Red Armour looks to need much more temperature and load to combust

 

[Keith Gandy]

I respectfully disagree. If that same line of thinking was used then the klotz original techniplate would be eliminated.

Jury is still out for me ...on them all. (well except super techniplate/benol - those are out!)

Another thought - there are those who believe that you tune the auto tune saws by oil ratio...or something like that.

I agree with ratio adjustment but if its not combusting its just the wrong oil for the application IMO. Look at Super Tech. Its combusting but dirty at the same ratio. One of the cleanest and fully combusting oils Ive seen yet is 2r. Dry in the top and good carbon

Why would it have to perform well at 32:1 if it can perform well at 40:1?

This is the top of the piston after about 4 - 8 tanks of red armor. Prior to that it had ruffle 20+ tanks of dolmar synthetic.

And this is the exhaust side. Idle to shut down and at 42.5 :1

Are you saying firewood operation needs 32:1? Or am I just reading that wrong? And are you saying milling needs more then 32:1

More oil on the bottomend bearings but still combust at 32to1. The less oil u use the less u will leave on the bottom bearings

U want ample oil in the bottom but full combustion in the top for max power

Entirely too rich or oil isnt combusting. Too wet

 

[Keith Gandy]

Seems the red armour is on par with the higher end motorcycle oils . Probably can get by with less oil

One thing to keep in mind though is these test r in 1 saw , an electronic saw, and could be totally different results in another 661?

2R is good stuff..

 

[Keith Gandy]

well I can't do everything. You have a 661. Run 4 tanks and open it up.

No 661 here Redbull. Just a thought for folks to keep in mind though that these test will conclude a result in that paricular saw but may differ in others? It should give a general idea whats goin on with an oil but with mtronics we dont have a clue what its doing with tune with each oil either? It can do what it wants with each

 

[bwalker]

I would also point out that after the mess ST made the results visually are skewed against the oils that follow given such a small test period.
