## Does engine oil affect fuel consumption?

You can improve your gas mileage by one to two per cent by using the manufacturer’s recommended grade of motor oil.

For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by one to two per cent.

Thicker oil is harder to pump..

## How far can you go with 1 Litre of petrol?

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’.

## How do I calculate fuel consumption per Litre per hour?

How fuel consumption is calculatedDivide the distance by the litres used to get the km/litre.Convert the km/litre to L/100 km i.e. divide 100 by km per litre.Convert km/litre to miles per gallon i.e. multiply km/litre by 2.825.

## What RPM should I run my diesel engine at?

Between 1,300 and 1,500 RPM is the most fuel-efficient engine speed, or what some would call the “sweet spot.” When you’re driving on the highway, aerodynamics become a key factor in the work required to move the truck. You have two options to lower the workload: improve the truck’s aerodynamics, or slow down.

## How much fuel does a diesel engine burn while idling?

Idling a heavy-duty truck consumes about 0.8 gallon of fuel per hour. Even when diesel costs as little as $2.50 a gallon, fuel for one 10-hour rest period will cost $20. Typically, a long-haul truck idles about 1,800 hours per year, using about 1,500 gallons of diesel.

## What causes a diesel engine to burn more fuel?

Worn or Fouled Spark Plugs. Dirty Fuel Injectors. Low Compression. Wrong Oil Viscosity.

## What is the formula to calculate fuel consumption?

The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption. (Litres used X 100) ÷ km travelled = Litres per 100km.

## How do you calculate fuel distance?

To estimate the fuel cost for a trip you must know the trip distance, the average per litre cost of fuel and the vehicle’s fuel consumption.Divide the trip distance by 100.Multiply the result of this by the fuel consumption.Then multiply this figure by the cost of fuel/litre.

## Do diesels need to be driven hard?

Driving a diesel engine hard will produce less soot per kWh of useful work. … Driving a diesel hard will also use more fuel. Use the torque which is what a diesel is about and let the DPF sort itself out as necessary, it works for most people like that.

## How can I make my diesel engine more fuel efficient?

12 Tips to Improve Diesel Fuel MileageTurn your engine off. … Use shore power when you can. … Avoid revving the engine. … Find your engine’s sweet spot and run with it. … Use your air conditioner as sparingly as possible. … Anticipate upcoming traffic lights. … Maintain an extended following distance. … Lower your average highway speed.More items…

## How do you calculate km per Litre?

To work out how many kilometres your car drives on one litre of fuel simply divide the total distance travelled by the total litres of fuel used. Example: 400 km / 42 litres = 9.5 km’s per litre.

## What is G kWh fuel consumption?

A consumption map or efficiency map shows the brake-specific fuel consumption in g per kWh over mean effective pressure per rotational speed of an internal combustion engine. … Average values are 160–180 g/kWh for slow moving two stroke diesel boat engines using fuel oil, reaching up to 55% efficiency at 300 rpm.

## How do you calculate fuel consumption of a diesel engine per hour?

Simple MethodFormula To Estimate Maximum Engine Fuel Consumption. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight. … 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.Other Related Resources:

## How much fuel does a generator burn per hour?

Gasoline Generator Gasoline is the most common fuel source for portable generators. A standard 5-kilowatt generator will typically consume about 0.75 gallons per hour. As of July 2018, the average price for gasoline is $2.89 a gallon in the United States.

## How many kWh is a Litre of diesel?

10 kWhOne litre of diesel fuel (auto) has an energy content of approximately 38 MJ – which approximates to 10 kWh (using a ballpark figure) but the efficiency of conversion into kinetic energy is only about 30% – that is better than petrol which is typically 25% depending on the design.

## What are the three main reasons for high fuel efficiency in diesel engines?

The diesel thermodynamic cycle efficiency advantage over the more common spark-ignition (SI) gasoline engine stems from three major factors: the diesel engine’s use of lean mixtures, its lack of need for throttling the intake charge, and its higher compression ratios.

## How do you convert kWh to MJ?

Conversion chart – kilowatt hours to megajoules kilowatt hour to megajoules = 3.60 MJ. kilowatt hours to megajoules = 7.20 MJ. kilowatt hours to megajoules = 10.80 MJ. kilowatt hours to megajoules = 14.40 MJ. kilowatt hours to megajoules = 18.00 MJ. kilowatt hours to megajoules = 21.60 MJ.More items…

## Can you over rev a diesel engine?

Diesel engine runaway is a rare condition affecting diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM and producing up to 10 times the engine’s rated output until destroyed by mechanical failure or bearing seizure through lack of lubrication.
