BogyDave - that is interesting and math can't lie?? I never did the math and I am not even sure what I pay for the little silver jugs of "Gold" evidently at 100+$$ per gallon. Makes 4$ a gallon for fuel seem cheap!

What I meant was
No small bottles for 1 gallon or 2 gallon of gasoline, so I don't have to measure.
Ever try to measure 2.6 oz or 3.2 oz of 2 cycle oil with the wife's measuring cups ?
Hard to be accurate & even worse if you get caught.
Alway wonder how much stays in the measuring cup.
How long will it drip as you wait to get it all out?
I like the small bottles so I can add some gasoline, shake & add it to the jug.
That way I think I get it all & have a good mix
One of my biggest complaints with AMSOIL is that they don't offer up Saber Professional in a squeeze & measure type bottle or in a 2.6oz bottle. They advertise it as a 100:1 oil but if you do the math, one of their little pillow packs for 1 gallon mix (1.5oz) comes out to be 80:1. Probably because it's a real PITA to rinse the packs out with gas if you're anal about the mix like me and Dave.
I'm still running the stuff and still liking it tho. 
Plus it's a cool electric blue color.

Lets see if I got this right.
I mix in 1 gallon jugs .
128 / x = 50 / 1
50x =128
x = 128 / 50
x =2.56
I'll save the small 2 cycle oil bottles & re-fill them.
& save some with a gallon of good synthetic.
I'll be set for a while.
2.7 oz wouldn't' hurt
I usually put .9 gallon in the jug & rinse the small bottle with gas to get it all.
All that said.
Now?
What's the consensus on what is "the best 2 cycle oil" for chain saws?

I got 6 of the 2.6 oz bottles when I bought the Stihl blower,
$15.54 for 6 pack of 2.6 oz bottles.
$2.59 for 2.6 oz.
$1.00 per oz.
$32.00 per quart
$128 per gallon
Definitely time to start refilling the small bottles.
The Amsoil INTERCEPTOR 2-Cycle Oil, synthetic is only $40 a gallon/
Yeah, not really comparing apples to apples here because we all know that buying bulk usually gets you a discount. Have not priced a gallon of Stihl HP Ultra mix, but willing to bet that if you buy it a gallon at a time that it will be cheaper than $128 a gallon. Thing is, I use one, maybe two, 2.6 oz bottles a year. Let's go with the high estimate of 2 bottles a year.
5.2 oz of mix per year
128 oz per gallon
128/5.2 = 24+ years
Buying a gallon of mix will last me until my kids are done with college. I still have tons of it left over from buying the saws and the trimmer. Bought the HP Ultra 6 pack to get the extra warranty coverage.
With that said, anybody know how much an actual gallon of HP Ultra mix costs?
That's why i bout the 6 pack/ warranty.
But will be buying a quart or gallon & refill the bottles.
Went thru about 8 or 9 gallons last year.
Have other than a chainsaw to feed too.
I'm a cheap skate

8 or 9 gallons of mix? You have got to be doing something for a living with this stuff or using a ton of it in play vehicles. That is just one heck of a gasoline bill using that much mix. At 50:1, that means you used almost 500 gallons of gasoline. At current prices, that is close to $2k in gas for feeding everything.
Would love to know what else you are feeding with 500 gallons of gasoline.
LOL
Of mixed gasoline.
Lets say 26 oz if 2 cycle oil.
Sometimes more if I fly much.
2 hours uses about 6 gallons of 50:1 mix gasoline:

Man, that is awesome. Made me wonder if I could do something like that here in Maryland. Highly doubt it though. Would probably require a cavity search, psychological screening, and $10k in licensing and insurance.
+1 Amsoil saber professional oil. I've been running it for the last 5 years in all my 2 stroke stuff...chainsaws, leaf blowers, trimmer. The leaf blower and trimmer are Stihl 4-mix products with OHV's. They're very particular about having two much oil and they've run great for me on this stuff. I also add a little bit of Sta-Bil or Seafoam to each mix to promote stabilization of the fuel.
I dump 1/2 a qt in a 5 gallon and call it good. No need to get all anal measuring down to the 0.001 oz.
I have one of those tall shot glasses with a scratch/sharpie line for measuring out my own. I originally wanted a test tube but this was about the same (tall and narrow makes it more precise...and can see through it), sits flat on the workbench, and is much easier to come by. The sharpie line wears off after a while, but there's I scratched a line with a file that I use to re-mark it every so often.
I dumped a 1 gallon mix container in and marked it.....now I just buy a quart and am good for a couple years.
I used to buy the one-shots, but they want crazy money for those.
Easy.

"48 packets of Saber Pro on the wall, 48 packets of oil!! Take one down, pass it around, 47 packets ......"
Yeah I'm good for awhile.
