Warm up the engine??

[Ry_Tower]

As per owner's manual, let the rpm settle sa normal idling level. During start, >1k rpm tapos bababa about 800 rpm in a few seconds

Ganyan sa gas engines, sa diesel may 1 minute talaga na ideal warm-up even with a fully functioning thermostat. Mas gusto ng diesel na medyo mainit kunti eh.

I always warm up the engine ---- I never load the engine until it is in its working temperature.

Simple as that

^^ agree ... 5 mins is too much

think in wintertime, they warm up the engine also because the engine coolant is used in the HVAC to heat up the passenger cabin. It usually takes a few minutes for the engine to become warm enough to raise the cabin temp.

maybe so, and that is just to help to warm the cabin. but in terms of idle time or waiting for the oil to circulate before driving, any more than 5mins is just a waste of fuel.

Mahirap magdrive kung nanginginig ka sa lamig. Kaya antay muna uminit cabin.

Modern engine doesn't need too much time to warm-up, 30 seconds max before driving away:

"In winter, don't idle a cold engine for more than 30 seconds before driving away."

^ for both petrol and diesel?

What's often forgotten is that idling warms only the engine – not the wheel bearings, steering, suspension, transmission and tires. These parts also need to be warmed up, and the only way to do that is to drive the vehicle. Until the engine temperature begins to rise, it's a good idea to avoid high speeds and rapid acceleration.

Paano if you're not using the car for at least 3 days?

^ sa lumang auto, longer time to warm up ang gawa ko
