To determine an average fuel usage at gallons per hour (gph), divide horsepower by 10. Therefore, a boater with a four-stroke, 250-hp marine outboard engine running at full throttle, or about 6,100 rpm, is using 25 gph.

Know that an outboard motor is most efficient at 75- to 80-percent of its rated output and revving back even a little yields significant fuel savings with the only cost being a longer passage time.

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. The storage life of petrol in equipment fuel tanks is one month.

Modern medium-speed marine Diesel engines burn about 0.4 lbs fuel per HP per hour. Thus, about 17.5 HP can be produced per hour for each U.S. gallon of Diesel fuel burned.

Fuel economy standard is an energy efficiency directive for motor vehicles in a certain country that prohibits marketing the vehicles with less than prescribed standard.

Wondering what is a good MPG? Any vehicle that has a combined MPG of 23 is considered to have a good fuel economy.

Four-stroke engines are more efficient due to less demand for fuel. Fuel is consumed once every four strokes versus two. Four-stroke engines are better for the environment due to reduced emissions. A two-stroke engine releases burnt oil into the air in addition to the exhaust produced.

Being more fuel efficient means; In a 4 stroke outboard engine, fuel is consumed once every 4 stokes and hence it burns less fuel, making the 4 stroke engine more efficient and environmentally friendly compared to a 2 stroke engine, as 2 stroke burns fuel and oil mixture.

In other words, fuel efficiency shows how far your car can travel with a certain amount of fuel. In America, the concept is described as "miles per gallon" (mpg). Vehicles with better fuel efficiency tend to consume less fuel to carry out the same task. Therefore, reducing wasted fuel.

Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km. You'll often see it referred to as 'fuel economy'.

Fuel economy is the distance travelled per unit volume of fuel used; for example, kilometres per litre (km/L) or miles per gallon (MPG), where 1 MPG (imperial) ≈ 0.354006 km/L. The higher the value, the more economic a vehicle is (the more distance it can travel with a certain volume of fuel).
