Total:

Add negative and positive points

Difference:

Subtract all the negative points from the positive.

If the result is negative, then the vehicle is equipped to the best possible extent.

Factor for determining the possible fuel saving

X 0.66

Determine the possible savings potential in per cent, by multiplying with the factor 0.66.

Result:

The calculated value provides information about the possibility of fuel saving in per cent, respectively the causes of high fuel consumption

Further influences

The factors listed below influence the fuel consumption considerably. However, as they are caused by use or the environment, they can only serve to evaluate the complete vehicle with respect to the complaint of high fuel consumption.

Load train gross vehicle weight/load increased
