Don't forget your tools, without the tools, Spare Tire is
useless when puncture takes place.
By doing b. and c., you will damage your transmission, ie. your
gears, not recommended.
To save fuel, always rev gently up to 2000 rpm (at least) before
changing up to the next gear, from gear 1st to 5th gear of course,
use 5th gear when driving more than 60Km/h. Always 'glide', ie.
clutch down and free wheel upon seeing red lights in front.
Remember to use Engine Brake to stop for safety, and to prolong the
life of your brake pads. Have a smooth crusing journey, avoids
sudden starts and stops.
"Lesser gear change means less high rev for the engine and is good
for the FC."
"Remember, more frequency of gear change means higher FC"
Not true, you need to change up or down according to the speed you
are travelling. The true fact to fuel saving is not to over rev
your engine unneccesarily.
"( the lower the rpm is maintain, the better the FC)"
Minimum rev is at 2000rpm when changing up to next gear as
mentioned above.
