All the gasoline here, regardless of grade, is E-10 gasahol. It doesn't
last as long in storage as 100% gasoline. So for 2-cycle fuel (which I
don't use a lot of) I've started using a shotglass when I mix it. The
shotglass is graduated at .5, 1.0, and 1.5 ounces. I mix 1.5 ounces of
good quality 2-cycle oil with .55 gallons of 89 octane gasoline for a
50:1 mix (it's just a little rich.) I don't add any Stabil, but when
it's 2 or 3 months old I pour whatever is left in the 2-cycle gas can
into my truck. Then I mix a fresh batch next time I need some.

I got tired of mixing up a whole gallon at a time and having it go
stale. Then I used it anyway, and it would eventually gum up my
carburetors.

I'm currently using Castrol (or maybe it's Penzoil) 100:1 rated TC oil
in a quart bottle. When that runs out, I may switch to QuickSilver PWC
(from Mercury Marine) synthetic oil -- the TC stuff, not TC-W3.

Now if I could just come up with a good method of remembering when I
last filled all my gas cans, so I know how old the gasoline is. (do you
think a blackboard in the garage would work?) I use Stabil in the
6-gallon cans for the generator, and dump them in the truck and refill
about twice a year. It's the little cans that I can't keep track of.

BTW, I buy one 2-gallon can of 91+ octane Premium gasoline in the spring
for the first tank or two of gas in the mower and tiller (etc.) They
seem to start easier that way. When that can is empty, I switch to
Regular for the rest of the season. By then they are either running
good, or they are not going to run good 'til I get them tuned-up. ;)

Interesting idea. BTW: Another useful gadget to measure oil is a
baby's feed bottle. Ours are long disused (Our youngest is now 30!)
and are graduated in ounces and millilitres.

I use Yahoo calendar for tires, and major appliances. It will send
you a reminder when to dump them.

Too much oil in the mix is killing your engine. It causes excessive
carbon build up which will eventually break the rings and cause other
problems.

Walmart sells what looks like a large plastic hypodermic syringe for
accurately mixing small quantities.

Also note that "marine" two stroke oil is not interchangeable with the
stuff for air cooled engines, which run hotter. Different
characteristics for different operating temps.

87 Octane will start better than 91 (although you probably can't tell the
difference). The higher the Octane, the greater the ignition point.

So-called "premium" gasoline was developed to prevent premature ignition in
high-compression engines.

I don't think gasahol is less stable but it is more prone to absorbing
moisture and too much water would cause separation. Addition of oil
would only add to the problem.

I see no need to worry about gas stored for less than a year unless it
is exposed to a lot of moisture and air.
Air/oxidation is what causes gas to gel. Gas should be stored in
filled, tightly sealed containers.

For my generator and in the generator itself, I add 2 years worth of
Stabil. After two years, the gas goes into my car and lawnmower. I
have a piece of masking tape on the cans with the date purchased.

Interesting idea about the premium gas. It may have extra carb
cleaners. In my Lawnboy, I found it best to use their 2 cycle oil as
it probably has detergents for this. I had been using a premium brand
of 2 cycle oil but was needing frequent carburator cleaning. Before
switching back to Lawnboy oil, I cleaned up the carb by adding cleaner
to the gas.

Near the end of the grass cutting season, I add Stabil to the gas and
leave the mower full. It is a good idea to start up any engine with
gas at least every 6 months as there may be evaporation in the
carburator causing blockage. This happened to me last year with my
snow thrower. Then I read in the manual not to use gasahol.
Alcohol increase the solvent power of gasoline which has been a real
PITA to everybody.

Why not use Stabil? I mix one gallon of fuel for the weed wacker and put
stabil in it. Sometimes it lasts more than a season with no issues. I
put it in the lawnmower and snowblower and neither has ever had trouble
starting at the beginning if their season.

For 20 years, I've been using a small soda bottle, a syringe, and
milliliters.

Originally, my intention was to shorten the required shelf life by
mixing less.

Soda bottles seal tightly, which means I don't lose volatiles or draw in
oxygen and water vapor. Concerned about reliability, I've always stored
the bottles outside. I've never had a bottle crack. In my experience,
a bottle will last years. Eventually, the seal in the cap goes bad.

With a transparent bottle, I don't have to remember if I've added oil.
It's easy to carry, easy to see how much is left, and easy to pour.

At first I used a 1-liter bottle. Now I use a 591ml bottle with a
magic-marker line for 500ml. Even full, it has 18% head space so it can
warm up without much pressure.

With a syringe, I can measure oil more precisely than with a glass. Not
much oil is left on the walls, and it's internal, where it won't gather
dirt. Because oil is viscous, a syringe needs big passages.

I make fewer mistakes with easy calculations, and working with ml makes
calculations easy. 500 ml at 50:1? I suck up 10 ml of oil with my
syringe and squirt it into the bottle.

Bottles have been decreed by your betters as absolutely UNSUITABLE as
containers for gasoline! They are dangerous! It is against the laws of God
and man.

I have seen some 2 cycle oil that also acts like Stabil. Or so it states in
so many words on the container.

I like approved gasoline containers. They resist bursting from being
struck. Their appearance warns of the contents. They even let some
people get away with pouring gas on flames. I watched the gentleman
next door pour gas from a 2-1/2 gallon can onto a trash fire. He's a
full-time fireman.

I'm leery of them indoors or in vehicles because they aren't always
leak proof if knocked over and don't necessarily hold fumes.

If I transport gasoline or keep it in my ventilated garage, it's in
approved containers.

If I mix 500ml in a bottle, I'll immediately pour some into a tank. So
I have perhaps 250ml. I stow it outdoors in a spot where it will be
protected from accidental damage and a spill won't mean a fire hazard.

I've always kept an eye on the condition of bottles because a small
spill would mean a small amount of environmental damage. I've never had
a spill. I'd probably spill more than 250ml a year trying to pour
2-cycle mix from approved containers into little gas tanks.

Mercury Marine is just the company name. Their "Quicksilver PWC" oil is
designed for air-cooled engines (it even says not to use it if your
engine needs TCW3), and the synthetic is rated JASO "FD" and ISO
(Global) "GE".

I just wonder if I could use very high grade oil at 100:1 even tho' my
saws and weed eater manuals all say to mix it 50:1 (actually, they say
to use 32:1 unless I use Echo brand oil; I ignore that part and use good
oil.) I may one ounce to a half gallon and see how that works. (64:1)
These are expensive very-high-reving engines, especially the big
chainsaw, and I'd hate to burn one up.

Gasoline degradation over time

The Chevron.com website has a on-line source that provides information for
your review. Specifically it says

22. How long can I store gasoline without it going bad?

Gasoline stored in a tightly closed container in a cool place will stay good
for at least one year. It is better if the container or fuel tank is almost
(95 percent) full. If the container or fuel tank will be in the direct sun
or will be heated above 30�C (80�F) much of the time, add an aftermarket
fuel stabilizer to the gasoline when you first buy it. Gasoline-oil blends
for two-stroke cycle engines stored under the proper conditions will keep as
well as gasoline itself.

As soon as I hit <Enter> I realized that I mistyped that; the ISO rating
should have been GD (there's not an E yet), and actually should be fully
spelled out "ISO-L-EGD". But there's more: I've tried to verify the
rating on this oil, in case I just read too much into the "synthetic"
part. and now I can't find any spec sheets anywhere. I've written to
Mercury but I haven't gotten a reply yet (and doubt that I will.)

It seems that most 2-cycle oil repackagers don't want you to be able to
compare their products, so they don't spec them any more specific than
TC vs. TC-W and TCW3.

With glass and plain gasoline, I can imagine the danger. It may be hard
to smell what's in a rigid bottle, and somebody wanting a gulp of warm
liquor may not want to smell it.

I keep it on a beam in a shed that's open on three sides. Kids couldn't
reach it.

Suppose an adult spots it and has a sudden hankering for half a bottle
of warm soda that could be years old. If he takes it down, the first
thing he notices is that the plastic cap is grimy from being opened and
closed with oily hands. The he notices that the fluid is dark blue,
unlike soda.

If he still wants a drink, it would be hard to get the short-necked,
flexible bottle to his lips without smelling fresh gasoline.

Somebody who drank from that bottle would probably also drink from the
fuel tank of a string trimmer, thinking the manufacturer was thoughtful
to attach a canteen for thirsty gardeners.

This is quite frightening. I am writing my congressman right

engines be clearly labeled:

"DANGER! DO NOT DRINK FROM FUEL TANK!"

There are 96 teaspoons to a cup measure. Two heaping teaspoons per pint

I tried it this weekend. 500ml water bottle full of StaBil'ized
gasoline, plus 10ml of Castrol 2-cycle oil measured with an old syringe.
It was just enough to fill the tank of my Echo weedcutter. (I didn't
know it had such a large tank.) I could probably mix the fuel directly
in the tank now that I know that, but it's a lot easier to pour from a
small bottle than from a 6 gallon gas can.

I don't know how long the syringe is gonna last. The oil may dissolve
or swell the rubber plunger and ruin it.

On the farm, where I did a lot of sawing and string trimming, I'd mix a
liter at a time. I used a piston syringe with a long tube, intended to
inject medicine down the throat of a lamb. As I recall, the o ring went
bad in a year or so.

The tube would reach to the bottom of an oil bottle. I used it with a
turkey baster, which lasted several years. Eventually the bulb cracked,
not from oil but from air. I replaced the baster.

With age, the tube shrank, which meant it took longer to draw the
required amount of oil, especially in cold weather. I should have
replaced the tube with clear 1/4" tubing just long enough to reach the
bottom of a bottle.

Now that I use a smaller soda bottle, I use a cheap plunger syringe.
Some cheap syringes may be impervious to oil. At a store the other day
I saw cheap bulb syringes intended to measure a dose of medicine.

You've got me thinking about using a soda bottle to transfer gas from an
approved can to my 4-cycle push mower. If I run out 200 yards from the
garage, that's half a mile of walking to fetch and return the gas can,
and I'm likely to spill some when I fill the tank.

Topping off before going out could reduce such occurrences, but topping
off from an approved can invites spilling. Besides, if I have to tip
the mower on the side, less gas in the tank means less chance of leaking
from the cap or through the carburetor. In storage, less gas in the
tank means less to lose by seepage, possibly into the crankcase. In
long-term storage, an empty tank and carburetor are probably better than
Stabil.

If I had to fetch a liter of gas for my mower, using a soda bottle could
mean no spilling, from the can to the bottle or from the bottle to the
mower. It could cut my walking in half because I could use a cord to
hang the empty bottle from the handle.

If I started out with a full soda bottle (or two) hanging from the
crossbar on the handle, I would never have to top off the tank because
I'd have a visible reserve. No more hassle if I have to tip the mower
on its side. If I didn't want the bottle hanging as I mowed, I untie it
at the work site. This could even make it practical to run the mower
dry before putting it away. Unused gas could be poured back into the
approved container.

My paint thinner comes in a plastic gallon jug like antifreeze. For
that much gas, I'd rather use an approved container. A paint-thinner
can could get knocked over, and the cardboard cap seals I've seen aren't
reliable. I don't know how well that kind of plastic would stand up to
gasoline. I'd hate one day to mix gasoline with paint by mistake.

To transfer gas from an approved can to a lawn mower, the size and
opacity of a paint-thinner can could lead to spills.

If I used a soda bottle for a visible fuel reserve for a 4-cycle mower,
I'd remove the label and write all over the bottle with magic marker.
I'd pour the gas back into the approved can when I finished mowing.

One fortieth of a cup.

Actually a teaspoon is 1:48 of a cup if that helps.

0.2 ounces of oil. Roughly 6 cc's if you happen to have a syringe
around or can get one.

6 ml is almost (5.9) spot on...the other way it's 1.2 tsp to guesstimate.

That's correct too. I used to work in a lab and have some old graduated
cylinders for stuff like this. My wife has a measuring cup in both
ounces and milliliters but graduations are not that fine.

To answer your question expressly, it will probably take less oil than
you have, unless you are out of oil. If you start with a cup of gas,
you'll need to add a tenth of a quarter cup of oil to it (alternatively,
you could instead add a quarter of a tenth of a cup of oil--which
depending upon how you go about it, may yield greater accuracy). This
will be facilitated by the use of a cup with metric graduations. Making
your own graduated measuring cup from a narrow cylindrical container
(think of a test tube), should give you results that are as accurate as
you please. If you would like to end up with exactly a cup of gas and
oil, the calculations get messier. It may be easiest to begin with a
cup of gas, proceed as in the first case, and then discard all but a cup
of that solution (well-mixed). Alternately, you could look up how many
teaspoons or tablespoons are in a cup (8 fluid oz.) and divide that
number by 40 to determine the amount of oil that you would need in terms
of those units (2 decimal digits will probably suffice, depending on
your purposes, if you are using a calculator). Don't smoke while you
are performing this work. Hope this helps! Good luck!

1 cup of gas = 8 oz = 1/16 of a gallon

if the container of oil you have is meant to be entirely mixed with a
gallon, take 1/16 of that oil and mix it with the gas. Or use 8/40 =
0.2 oz of oil for a 40:1 mix.

If you use a good brand of 50:1 oil you can mix 1 tsp oil with 1 cup of gas.

Thank you thank you thank you I just hardest time with math and I was searching for you so please give me answer for quite a quite a while and I think I got it and I'm not sure is now it's to the point where I have to know it for sure because I'm borrowing very expensive piece of equipment and I don't want to burn so I thought I was right came to me that it must be a teaspoon that had to me and that it was always better to err on the side of too much well then not enough and it's still so it needed to be 15 orange anyways thank you for confirming the so awesome and now I'm subscribed bless you

There is premixed two cycle fuel available if you don't trust your math. Home Depot, Harbor Freight, Lowes, and Menards have some. Your local auto parts store might too.

There is this funky thing called a full stop on the right hand end of the
bottom
row of keys above the space bar. It makes your stuff easier to read.

This coming from the senile Australian sociopath who actually wrote this:

"But it can make a lot more sense to realise that the
really stupid will get the operation they bought
the phone from to set it up so it can be used
than to try to explain to the most stupid who
don’t even understand what a sim is for how to
get something so small and fiddly into an iphone."

For the small amount of weed wacking I do I would never buy anything else but the premixed.

However this year I bought a rechargeable string trimmer, and greatly to my surprise I am VERY happy with it.

If you ask your pharmacist for a 10cc syringe they will usually give
you one. It is less than a buck if you have to buy it.
10ccs of oil is 50:1 in a pint of gas. That is about what my chain saw
holds. The weed whacker holds about 350cc of gas and 10 ccs gets close
enough to 32:1 that I can live with that. Why would I fool with very
expensive premix that may be months old by the time I get it when I
have fresh gas here and I can mix it as I go?
