661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[glock37]

so the 3 quarts of h1r is no good to me anymore

I got a lot of oil to burn now I guess ill have to mix it 40 to 1 then and be done its good oil and wont hurt a thing

I got a quart for a guy that mills with a 880 and he burnt it up again at 50 to 1 stihl ultra he knocked the intake clamp off

im recommending to him 32 to 1 belray for milling double 880's on a 9 ft bar

When I run out of 800 off-road I'm trying the cheapest 2-cycle oil, mixed at 32:1, and compare.

I've always been of the belief that any oil with a well known brand name label (someone with a reputation to protect) will be of high quality... regardless of what certifications it may or may not carry. With 2-stroke small engines I shy away from oil with multiple mix ratios on the label, or those that claim to be "safe in all two-cycle engines"... like I posted several pages back, in my experiences a Jack-of-all-trades is a master of none. (but, everybody ain't me)

There is no "oil test" or oil thread that's gonna' convince me to change what's worked (for me) for something over 20 years in several pieces of OPE. It don't matter to me that it ain't the latest-'n'-greatest, all that matters to me is my stuff starts and runs when I need it to without breaking... what more can I ask for?? (but, everybody ain't me)

I ain't a pro... I don't use enough fuel to worry about a few pennies on the oil either way... so I don't price shop. (but, everybody ain't me)
I don't have any ported/modified equipment (yet ), so I mix it at the ratio I mix it at. (but, everybody ain't me)
Am I sayin' I'll never change?? Nope, I don't burn bridges behind me. But I am sayin', after 230 pages, I ain't read anything to convince me I should change anything... so, as of today, I have no intention of changing anything. (but, everybody ain't me)

And finally, I will not slam, put-down, or denigrate anyone for making the choice to use whatever they want, at whatever ratio they feel comfortable with, for whatever their reasons... one thing this thread has shown for sure... everybody ain't me.

Now yamalube is gonna fly off the shelves

then..next year..it will be something else , and it will be garbage.

any predictions ?

Sounds about right to me. [emoji6]

I gave up reading this thread on page 173
I have a 440 that has well over 1000 gallons of gas through it
no signs of wear on the rings, piston or bearings
i'm using a tcw3 oil since new at 32-1
it's also ported
schaeffers two stroke

Awwwww, isn't that cute.... Mastermind when he was a little feller......

Exactly. No testing what so ever has been done to show that any one oil is any better than another (except that H1-R doesn't seem to burn so well, at least in MTronic saws at 32:1). That's why I tell my customers, pick a good full synthetic oil that's available locally, and run it 32:1, no less than 40:1. You're not going to go wrong with that recommendation.

Another great choice.

No one here is capable of conducting a truly scientific test to prove what oils is best. As such I reccomend running an oil carrying the latest air cooled certifications or one with a very long track record of good performance like 2r.

Washing the cylinder walls of oil with raw fuel isn't a good thing.

Except it isnt raw fuel ............. its mixxed with oil, and according to you .............. its evaporated, so how is it washing anything ?

If the air/fuel ratio is rich enough to wash a piston clean the motor is running cool enough that a good portion of the fuel isn't vaporised.
I know this is some strange concept to you, but it is FACT that liquid gasoline can't be combusted and in a properly running motor fuel that reaches the combustion chamber is in a gaseous state.
Instead of trying, albeit feebly to discredit me, why don't you try to correct your ignorance?
And for the record, I didn't see your stupidity earlier or I would have addressed it then.

So lets say its doesn't combust as readily as K2 wouldnt that be better that it pukes it out the exhaust as opposed to possibly leaving more carbon?

No, because partially burnt/ unburnt oil leads to carbon. Especially in the exhaust port.

What's the definition of a clean burning oil? What should the piston crown and exhaust port look like? I guess I'm too rich since my piston crown and exhaust port, 660 & 036, is almost spotless after two liters of 800.

 

[KG441c]

1 liter of 800t in a ported 461 tuned @14200 to 14400

 

[cuttinties]

Hmm

Does racing fuel, like Sunoco 110, burn cleaner than regular gas in a premix?

The trapped compression ratio is far too low on a saw to see any benefits of higher octane fuel

I've tested 110 vs 93 in my ported 660 with a 212psi compression. The 110 tuned to 13,500 and the 93 tuned to 13900. The 110 cut times were greater than 10% faster.
