'if the outboard you have is a pre mix model use 50 (fuel):1part (oil) or 16oz. (1 pint of oil) to 6 gallons gas. be sure to use high quality gas, it is much more important to use better gas in your outboard then say your car or lawnmower, this is because your car usally runs at about 1500-2000 rpm compared to 4-6000 rpm in your boat. use good oil, tc-w3 is what to look for on the container, but this does not mean they are good, donot use supertech or other off brands, your bes bet is to use manufactuers oil, (merc is quicksilver, Yamaha is yamalube, ect).
ischemic stroke
You're talking about damage to the brain. It depends on where the stroke occured, but the effects could be anything, from spasms to memory loss (most common) to mental retardation, etc.
No, crude oil used to make Petroleum is the most common type of fossil fuel.
It all depends on where the stroke is located and how extensive the area the stroke affects. The brain, which is were most strokes occur, does not replace dead neurons. Sometimes if the stroke is not too extensive other parts of the brain can take over. Physical therapy can sometimes help find those other parts of the brain.
oil
i would say 50:1 most 2 stroke outboards are 50:1
Most all models of Yamaha outboards can be operated on a 50:1 fuel to oil ratio.
Most late model Johnson/Evinrude outboards carry a decal stating a 100:1 ratio. Being an old timer, I still prefer the ol tried and true 50:1 ratio, one pint of 2 cycle oil to six gallons of fuel. Never seen a powerhead failure due to the richer oil mix.
32 to 1 is the stock ratio. Most modern 2 stroke oils can be mixed leaner.
Like most outboards, it uses a 50:1 fuel to oil ratio. This is equal to about one pint per 6 gallons, or 2.6 ounces per gallon.
They are - most inboard engines are 4-stroke. But as with land vehicles, you can get a smaller engine with 2-stroke (or more horsepower with a smaller engine) so the small engines like some outboards tend to be 2-stroke.
50:1 is used by most OMC 2 cycle outboards.
Most of the larger outboards are two stroke, unless it is very new. Most 115 Mercurys are inline four cylinder, except the very first ones built in the 60's and early 70's
Most will do fine on a 32-1 ratio
Most board scooters or old mopeds are two-stroke engine. This means that they mix the fuel with oil (two cycle oil). Usually the ratio is 1:20. Most four-stroke-engines mopeds have their oil cap under the seat.
Most 2-stroke engines require 4 OUNCES of oil for every 1 GALLON of fuel. Some engines require more or less so you should check your owners manual, but this is the common ratio.
50:1 ratio 16 oz 2 stroke marine motor oil to every 6 gallons of gasoline this is most common I use this mix ratio in my 80 hp mercury spitfire
