Battle of the Transmissions: M/T vs. A/T

[dr. d]

turn off the engine on traffic? diba mas malakas sa gas yun pag ni start mo ulit..

an engine turned off does not consume fuel. but upon starting, some engines settle immediately to its usual idling rpm of 700-900, while other engines, like mine, first go to a higher rpm, then go down slowly to the usual idling rpm.
what i did, was to observe how high my starting rpm would go, and how fast it would settle to the usual idling rpm of 700-900 per minute.
with those in mind, i figured, rightly or wrongly, that my break-even stoplight time, was 30 seconds.
if the stoplight lasts more than 30 seconds and i turn off my engine, "i am ahead".
if the stoptime is less than 30 seconds and i still turn off the engine, "i use up more fuel" when i start the engine than if i just kept it running.

it keeps me entertained.
