Warm Up?

[Wes]

I usually just wait for the RPMs to finish dropping to its normal idling then just go normally (not fast), or if I am in a hurry I just go but more gently until it warms up.

Chances are that your pistons will be knocking against your cylinders in colder revs with all that free-play...
Even worse when rev'ed high creating pre-mature wear and tear when not warmed up to operational temperature.

this is very true being a mechanic its important to me to let engine oil temps raise it properly lubricates the main bearings and lets oil to circulate in the heads. also remember we are using all aluminum blocks and heads to our engines in the past the phase 1 ej25 engines from the mid 90s legacy gt's and impreza Rs's had head gasket problems.

this is because most people turn the car on and drive blast the heat , this is winter driving most people ive seen have blown head gaskets because the expansion and retracting of the metals from going from cold to hot to cold again real fast rather then waiting a few minutes to let the engine reach proper temp and expand to the proper size.

also it wears the internals like cams pistons and what not inside the engine without proper lubrication. my advice to most is before you set out turn the car on let it sit for at least 2 minutes let that engine warm up a little bit. it will only give your engine longer life. ever start the car and just try to drive it it feels sluggish and the transmission feels notchy and strange feeling ? its because its not properly up to temp yet. all the fluids are still kind of thick and not warmed up.

I always start my car then walk 30m or so up to the front gate to open and then back before the car moves so it's gets a min or two to warm up then I have to close the gate aswell so my temp gauge is usually off cold by the time I depart the driveway.

not true,but it won't hurt anything if ya wait the 3 minutes,if it gives ya peace of mind! ideally ,once oil pressure is established,you are ready to run! would be better to have an oil pressure gauge but it's not absolutely necessary,as oil pressure is virtually instantaneous upon start up...just keep revs down untill you reach operating temperature. (few minutes max) runnin' 0-20 synthetic,oil is very light,but extremely tough,durable,AND slippery...just sayin'

starting the car and letting it idle is "not" the smart play! car will reach operating temperature "faster"(with subsequent internal wear reduced) if it is driven (moderately,keeping revs down) right away after establishing "oil pressure".if you let the car idle,wear on internal parts WILL be "increased" because it will take that much "longer" for the car to reach optimum operating temperature. this is well known.

My cousin (master tech) says same thing according to him in Europe it's illegal to let your car idle for more than 45 seconds. I guess I'm just used to 10w60 in my BMW lol that stuff takes a minute to warm up lol. But it glides like butter. Thanks for clarifieing :happy0180:

I wish all cars came with oil temp, and oil pressure gauges . As well as volts.

This probably isn't the right topic for this, but I'm curious about this warm up time. When I first start mine it starts out at about 1100 rpm's, then if I let it idle it goes to about 500-600. Is this an issue? Should it stay around 1k?

[BMWDavid]

As others do I wait for the fast idle mode to drop down and then motor off. I keep the revs under 3500 and use part throttle until fully warmed up.

No, all cars idle higher when started then drops. This car just more noticeable than others, well for me since my old car you wont hear when idle goes down.

That's great until you realize the rich fuel delivery at start-up can create carbon build up. Just like those people who start their carbed motorcycle and let it idle with the choke open...it should be removed as soon as it can idle without the choke. All those pre-mature wear talk is from the 70's at best.

It's pointless to just leave a car warm up, just driving it gently after 10-15 seconds will make the engine warm up faster anyway and you don't waste gas.

True, but I'm not talking about 5-10 mins idles here. I usually only idle about a min or two, just enough for me to open the back gates and close them on my way out.

The high idle helps bring the oil pressure up to speed.The worst thing you can do is start it and immediately start dogging it under 1k.

Any internal combustion engine needs sufficient time for thermal expansion.If you are the type who flogs them when they are cold or never hit operating temps in your commute,you are slowly destroying your engine.

I always let it come down from high idle to at least 900rpm.I also noticed when the fRS sits for a day or 2( i also drive a truck) or the temps are cold,it takes much longer to come down from 1500k
