switching off the engine

[OTEP]

even if the engine rarely reaches 2.5k rpm? delicate pala turbo diesel engines

Yes, because the turbo is spinning far more faster than 2,500rpm. Same applies to turbocharged gasoline engines.

same question here... for non-turbo vehicles, is there a proper way of switching the engine off?

ako kasi, i rev the engine muna before turning it off eh... :D

thats a no-no.besides wasting gas, i read that it has detrimental effects connected with sludge...or something to that effect.

That practice harks back to the day of old-school carb engines. Though I don't really get the point of doing it nowadays. Even newer carb engines can get by without it.

sabi pa nila noon araw..
since nag rev ka nag charge ang ang battery mo
comes from alternator sabay click off ng ignition switch

mura pa kasi gas noon araw

IMO, pag may turbo, idle for at least 1 to 2 minutes, for long drives, at least 3 to 5 minutes. Pag walang turbo, turn off the engine right away, don't rev, sayang lang gas or diesel.

[geode]

dont rev ... sabi nga sa previous posts, sayang lang gasolina.

after parking, i do the following: check handbreak (nakalimutan ko dati and when i came back sa car ko it apparently rolled slowly onto a van .. ouch!), turn off radio, turn off lights then turn off the engine. i usually turn off the a/c more than 3 blocks away from the house.

yup.. ok lang to turn the engine right away. pero madalas parang automatic na yung paa ko to rev before turning off the engine.

For non turbo engines, you can turn it off right after shutting off the a/c, radio, etc... No cool down needed here. Idling and revving will just waste gas usually.
