Various factors influence fuel consumption:

points.
Your
warm up.
When the engine is idling, it takes a very
long time to warm
up. Moreover. during
warm-up, both engine wear and exhaust
gas emissions are very high. Therefore, be
ready to drive
off immediately after starting
the engine and avoid high engine speeds.
Avoid
Upshift as early as possible -do not drive at unnecessarily high engine speeds.
The highest fuel economy and the least di­
sturbance to the environment are attained
when you drive at l
ow engine speeds and in
the highest possible gear.
For example , fuel consumption is twice
as high in 2nd gear as it is in the highest gear.
Downshift only when the engine is no longer running smoothly.
Depending on the transmission you have.
you can normally drive in the highest gear at
25 to 37 mph

Avoid driving at high speed.

For example, fuel consumption increases in
