Oil Mix Ratio

[glens]

Is it morning or afternoon on the south pole?

The <i>real</i> extra credit question is:

Do they put enough oil in the pre-measured jug to compensate for what's left behind after merely letting the jug sit upside down for half a minute in the gas can filler?&nbsp; Or were they exact and you're supposed to rinse the can to get it all out?

It could be especially pertinent in the jugs for mixing one gallon of fuel.

not that much. According to Dagger there is a safety factor of 1.25 -1.50 on the oil mix.
"...now.in that much fuel, we put in the amount of oil need for lubrication..as dictated by above criteria..add a certain safety factor..(industry standard of 1.25 to 1.5 ) to help us get thru the warranty period whilst all them "EXPERTS" were fooling with the carb adjustments to make em run faster."

I think Dagger is full of crap on that point. The bearings, cylinder coatings, ring material and type hasnt changed since the mfg switched to higher ratios. Also tyhe oil ratio of a two stroke is dictated by load as much as engine design.

Everyone here is full of crap on every point! I could go into detail
but the calculus involved would confuse the junior members,
as they cannot even understand simple topics like octane and
synthetic oils, but I digress...................

Ben,
I've pointed this out before, but here it is again. Mid 70's Partners used a 50:1 mix. Their cylinder walls are chrome. That was pre-EPA and pre-nika-sil.

Fish,
Even us old-timers are in awe of your detailed digressions.

I just e-mailed Dagger to come back and whip you girls into line!
If only Walt was still alive, we could teach you all some real
chainsaw knowledge.

OK J.C.

Oil Ratio: It's a rocket science thing. Let's run this post up to 20,000 views. I'll bet we can have it past "Greffardized" in a month.

Ok.

Oil ratios are easy, just remember that there are 128 oz in a gal, that imperial gallons are bigger, but Canada is getting away from the 5qt gallon. A quart is a quarter of a gallon, ( except as mentioned above) for 32 oz, and .946 of a liter.

Or, you could keep in mind that the difference between 32:1 and 33.26:1.04 won't make as much difference to modern equipment as fresh, clean gas, quality oil, a decent maintenance plan, etc.

I have been using a mixing cup,made by Maxima.
No thinking is required.
It has the oil ratios marked at the top,lines underneath, for how many Gallons or Liters that you want to mix.

I am just going to buy all used saws, and specify they ship them to me with gas. When they are empty, I will just buy another one. Glad I built the big garage.

I don't care about this oil ratio thing...all I want to know is ...Where can I get a can of Molson like the one in the picture Dennis posted

[jokers]

Hey Jeff, you can get those cans of Molson in any of the grocery stores around Oswego. Also the local pubs that cater to the hockey players. Grab a few next time through on the way to camp.

Glen's idea about reusing an old 50 to 1 stihl bottle and then adding more oil to get 32 to 1 is funny because those bottles hold a lot more oil than the amount that comes in them. You'd have to buy a case of splitfire plugs and a gas mask, if you did that!

Wrong

That's easy. Try taking one step east from there.

Thanks Mike, for picking up the element of humor in my post.&nbsp; I had actually not intended on using any old jugs for measuring purposes (that truly would be silly), but rather that a six-pack of each could be purchased and for each 2&frac12; gallons mixed, just dump one of each in.&nbsp; The humor involves the added expense of buying the oil that way (and for me, the desire to deviate from the specified 50:1), but there truly is a practical side of it in that no measuring devices need be obtained, used, or stored.&nbsp; Not to mention that there would never be any doubt about what's in the can when it and the two empty jugs are all present.&nbsp; Perhaps the worst aspect of the method would be that it's not very "green".

Stihl088stock, I think you mis-read that. I think WRW had the answer right but didn't type it, if you were on the south pole the first step you took in any direction would be north so taking one step east from the south pole is what would be impossible.

 

[WRW]

Thanks for the vote of confidence, sedanman.
I talk more than I write, so I find it easier to tell 'em what I'm saying than to write what I want 'em to read.?
Reading writing is sometimes confusing, too.

I guess I'm digressin'.

 

[Fish]

Old jugs?

 

[Stihl088stock]

just making sure

It's hard to detect cynicism sometimes, taking one step east implied that east was the answer to me.
