The proper way to mix gasoline/oil 2 stroke engine

First We must know what is the right oil ratio to our engine
Ej: 100:1,- 60:1,- 50:1,- 40:1,- 25:1
After makinng the mixtute in a gasoline container add the oil and shake so that mixture are uniform.
(careful with fumes)..

Now put in our boat tank with assurance that we have a good mix gas/oil.

I say this because in my case
My boat have a 40 gallons tank..
And when I need filling only i stopped at the first gas station that I found on my way.
Putting the gas in the tank ej:
20 gallons. Them add the oil 60oz. And go to the water.

Tha engine sounded terrible.
Did not lose power but sounded disastrous....
No had a good lubrication.

This is right or I'M wrong...

Re: the proper way to mix gasoline/oil 2 stroke engine.

Yes, oil first, then gas . . . so that the oil will mix with the gas.

Did you damage the engine in your recent outing?

Re: the proper way to mix gasoline/oil 2 stroke engine.

Most outboards use 50-1 or 1 pint to 6 gal.
To add oil/gas first put in 1 pint of oil then add 6 gal gas.
Then you can dump the rest of the oil and add the gas.
My way is I measure how much gas I need???
Then I put in 1-2 pints depending on the gas??
Then add 6 or 12 gal.
I have 3 different size oil containers. 1 for 3 gal 1 for 6 gal and 1 for 12 gal.
That way I can add oil for the right amount and not add too much.
Too much oil setting in the bottom will just add too much oil and carbon the rings.
You need some way to mix the gas.
Siphon off some of the gas/oil. Then add it back into the the tank, do this a couple of times until it's mixed.
The oil/gas if left alone long enough will seperate and the oil will settle to the bottom. Will take a long time to do this.

another question
which is the oil recommended
for force outboard

Re: the proper way to mix gasoline/oil 2 stroke engine.

Any oil that is rated TC-W3

TC = ( two cycle engine )
W = ( water cooled )
3 = ( newest version )



petrol or synthetic

If it is rated TC-W3, it should be self mixing. Just add the oil, then add the gas.
Also, it will not separate.

Re: the proper way to mix gasoline/oil 2 stroke engine.

The motion of the boat surely mixed the oil fine by the time you got her launched.
50:1 2.6 ozs per gallon.Most oil containers are marked in ozs.
The worse that could happen is there might be too much oil.But motors used to run fine
at 8 ozs per gsallon and that was with straight 30 weight non detergent oil.
Is this boat new to you?If new to you did you get a test ride?
Describe in detail how the motor acted.Likely the motor just needs some attention.

Re: the proper way to mix gasoline/oil 2 stroke engine.

60 oz of oil per 20 gal of gasoline is a 42::1 ratio, which is a bit rich for a normal engine that runs 50::1. You will get more smoke and maybe some rough running.

20 gal of 50::1 mix would require 51 oz of oil.

Re: the proper way to mix gasoline/oil 2 stroke engine.

BTW - I I were you, I would add the oil in increments, as you add gasoline to the tank. If you know the tank will take 12+ gallons, toss in a qt of oil, and then add 12 gal gasoline. Now if you think it will take 6 additional gallons toss in a pint of oil and add the gasoline. Next if you think she will take an additional 3 gas of gas, toss in 8 oz of oil and then the gasoline. Continue adding 8 oz oil and 3 gal gasoline until she is close to full. If you fail to estimate the last 3 gallons of gasoline correctly, you will only have a little bit of extra oil, which is acceptable.

Re: the proper way to mix gasoline/oil 2 stroke engine.

Never thought of it as a problem before. But then I use 6 gal removable tanks. Shaken, not stirred.

Keep your OMS functional and fill the oil reservoir and the gas - Go boating - No problems, no mixing, no guessing, no spillage, no fumes no mess

No oil injection on those motors.

Re: the proper way to mix gasoline/oil 2 stroke engine.

my question is if the oil is mixed well with the gasoline
putting the oil in the tank without shake,
thank.

force motor No have a oil injection

I bought several brands of oil
and in some cases in the container said
the ratio is 3 oz to 50.1 in other that are 2.6 oz
which is the true

Shaken, not stirred 007 jaaaaaaaa.

Re: the proper way to mix gasoline/oil 2 stroke engine.

i think if i had a built in tank, i would premix in a gas can first. but thats me, i may have ocd

Re: the proper way to mix gasoline/oil 2 stroke engine.

1 gallon is 128 ounces, so 50:1 would be 128/50 = 2.56, or roughly 2.6 oz/gal. Your motor might have sounded horrible if you got some bad gas, or ran too low of an octane. Some motors are more picky about gas than others.

The risk of putting oil in last, is in some boats the gas tank filler hose is not a strait shot to the tank. If there are any bends, or if it doesn't slope downward the whole way, then the oil might sit in the tank filler pipe instead of making its way into the tank. The result is not enough oil in your gas. If your boat isn't like this then that's not a problem. Assuming you're on a trailer, then if you're filling a tank that isn't entirely empty, you're probably fine adding the oil and then the gas. It will be shaken during the drive to the boat launch.

Put in the right amount of oil and add the gas it will mix fine.
2.6 ozs is the recognized ratio.3 ozs is not enough difference to talk about.
If you get right down to it a gallon of gas weighs less than a gallon of water So you can't really
say quart is 32 ozs and a gallon 128 ozs when talking about different liquids.
If you multiply 2.6 ozs by 50 you get 130 ozs. 130 Devided by 4 = 32.5 oz per quart.If you multiply 3 ozs by 50 you get you get a gallon is 150 ozs. Devide by 4 =37.5 ozs. per quart.Perhaps they are dealing with the imperial gallon which is bigger than the US gallon.
Imperial gallon is 160 fluid ozs,US gallon is 128 Ozs.US pint is 16 fluid ozs imperial pint is 20 fl ozs.
Imperial gallon is 4.54 liters. Rounded down. A liter is 33.8 fl ozs.

2.6 oz/gal is 50:1

3 oz/gal is 43:1


This is ounces of volume (1 ounce of volume is approximately 29.6cc, or .296L), not ounces of weight (1oz of weight is approximately 28g, or .028kg). Two totally different things. Adding the volume of 2.6 oz of oil to the volume of 128 oz of gas will give you roughly 50:1 ratio of gas to oil, by volume.

Re: the proper way to mix gasoline/oil 2 stroke engine.

Don't make this so difficult. One pint of oil in 6 gallons of fuel is a 50:1 ratio. When you add fuel do it in six gallon increments. Add six gallons and then add one pint of oil. Add six more gallons and add one pint. As you approach a full tank, add three gallons and add 1/2 pint. You can use any oil that is branded TCW-III or TCW-3
