I'm anal when it comes to warming engines up, both the bike and car.

Car doesn't go over 2.5k rpm until the needle is buried in the middle of the guage and has been for a minute.

Bike doesn't go over 4k revs until it's hit 75c and sat there for a minute or two.

Is this really necessary on cars nowadays? As I see people getting in their cars and not caring.

Am I too careful or does everyone else simply not care/know?
 
I wait a while as my car seems to feel better once warmed up. Revving above 3.5k not long after starting I think I can hear it telling me to go **** myself.

Surely oil is oil and needing it warmed up properly still applies?

I also go up a hill straight from my house so I tend to keep it in a lower gear meaning less overall throttle up the hill too.

The revs arnt the important part, its how much load you put on the engine. Ie keep loads as light as possible

It's important not to be excessive with both, on a cold engine. Engines are at their most efficient and long-lasting when they're up to correct operating temperature. The quickest way to reach this is to drive normally, not leaving it idling on your driveay, so just drive smoothly and gently for the first 5-10 minutes
 
My warm up procedure:
No more than 3K RPM
No more than 1/2 throttle
Keep boost to a minimum

All until the oil temp gauge reaches at least 75C

Both of mine take about 2 mins to get to full water temp, oil temp follows shortly after

I do laugh when I hear a neighbour thrash their car off up the road in the morning.

Some cars get such an awful life
 
My girlfriend's 07 plate Focus water temp is up there in about 2 minutes, mine takes a good 5-10 and 2-3miles to get up there.
 
for info, oil takes about 5x as long as water to reac running temp on some cars. most people go by water temp, which means F all to if you should rev a engine or not.
on any my sporty cars my from cold start procedure is start up, let idle for 30 seconds until oil pressure stabalises, drive up gears easy def no boost and hold steady revs, as temp comes up maybe hold car in 4th instead of 5th a bit longer, then gradually feed in boost/revs. generally 10-15 min at a 50mph cruise should see close to running temp,
 
My MX5 warms up very quickly. My diesel Focus takes bloody ages.
I take it easy until the temperature needle has at least started moving.
I would never floor it until the needle is at (or very near) the correct temperature. I also ensure for the last few hundred metres of a journey I stay off the turbo completely in the Focus, as the last thing I want is a turbo spinning with dry bearings.
 
Terrific, so your post is as good as f all too then.

I don't even think many cars report oil temp to the ecu so you wouldn't be able to get that from obd

No i would say my post is quite good actually, as it shows i have seen it a lot of times roughly how long it takes oil to come up mate. And now have informed people how long it does take that didnt know, that to wait another 5-10 mins after water temp is up, if you care, or drive anything sporty. Sorry if came across anyway badly
 
The only thing i've seen with an oil temp gauge is my mum's Audi cabriolet but looking at images on Google I don't think the gauges in her dash are standard.
 
My commute to work is only 12 miles, roughly 25minutes, 86k miles and the car is still going, 21k miles on the bike and it still pulls like a train.

Manufacturers must have to plan for people getting in their cars and driving off at whatever pace they feel like at that time, oil technology is far better than it's ever been, cylinder liners are better... is it truly necessary to worry about it after 2-3miles of slowish driving?
 
This is why I love all the gauges on the screen in my car, I always wait for engine oil, engine coolant and gearbox oil temps to be up above 70c before getting on it.

Doesn't take very long by just driving normally and shifting around 3.5-4k.
