Recommended by Yamaha and Suzuki for most of their small two stroke engines up to about 30hp, this ratio requires the least amount of TCW3 two stroke oil. The result of using this ratio (less oil) is reduced spark plug fouling and less smoke.
What happens if you put too much oil in a 2 stroke outboard?
Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power
. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel.
What ratio should I mix my 2 stroke outboard?
Use a
40:1 two
-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil.
How many ounces is a 50 to 1 oil ratio?
For a 50:1 ratio of gas to oil, use
2.6 fluid ounces of oil per gallon of gas
.
What does 50 to 1 gas oil mix mean?
The mix ratio is the proportion of gas to oil, expressed as a ratio. For example, 50:1 means
50 parts gas to 1 part oil
.
Can I use regular 2 stroke oil in my outboard?
Two-stroke outboards require oil
that meets the TC-W standard
, which indicates a marine oil designed for a two-stroke engine. Again, consult the owner’s manual for specific two-stroke oil requirements.
Which has more oil 40/1 or 50?
The maximum amount of oil in the 40:1 ratio standard means
3.2 ounces of oil per gallon of gasoline

How long will 2 stroke fuel last?
As for sealed containers it states: The storage life of petrol is one year when stored under shelter in a sealed container. Once a seal is broken the fuel has a storage life of six months at 20°C or
three months at 30°C
. As stated earlier, “fresh is best” so be sure to mix smaller batches more frequently.
Can you use too much 2 stroke oil?
It’s important to get your fuel
-to
-oil ratios right when mixing two-stroke fuel. Too much oil, and your engine may struggle to start or run, generate carbon buildup on engine internals, blow clouds of smoke and perform poorly in general.
Can you fix a 2 stroke engine that ran straight gas?
First of all dump out all the fuel from the tank. Then refill the tank with the proper fuel oil mix. Pump the primer bulb until you see fuel in it and pump it a few more times to get any straight gas out of the carburetor and back into the tank where it can be diluted.
How do you calculate a 50 to 1 ratio?
You want to mix
2.6 ounces of oil to one gallon of gasoline for a 50
:1 mixture. If you’re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture. I would recommend using fresh gasoline that has an octane rating of 89.
How do you calculate a mix ratio?
Divide 1 by the total number of parts (water + solution)
. For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9).
How much oil do I need for a 25 to 1 ratio?
To make 25:1 use the
2.6 oz two cycle oil to a 1/2 gallon of gas
. That’s the simple way.
What is special about 2 stroke oil?
The oil circulates without being burned. A 2-stroke oil
will lubricate the engine components by association with the fuel
(either by mixing with it or by spraying during combustion), so this oil contains components that promote its combustion.
How much oil goes into a 2 stroke?
What is the ratio for 2 stroke fuel mix? You should follow the ratio provided by the manufacturer of your power tool. If do not know what it is,
