I try not give it too much grief when cold, not booting it until the water is upto midpoint. Although I was told that oil heats up faster than water inthe engine so I could probably use boost earlier than I do.

Who told you that lol. The oil takes LONGER than the coolant to hit it's operating temperature. Sometimes a fair bit longer in cold weather.

 

See this...

Yup, even more so in our diesels. 

Not necessarily, turbo engines heat their oil much faster since the engine oil is also cooling the turbo bearings, also modern fully synthetic long-life oils stay 'in-grade' across a very wide temperature range.

 

There is a lot of rubbish written about 'running-in' and 'warming-up', particularly by Americans who in fairness have to work with crapulent N/A V8 engines which are VERY badly made and very inefficient.

 

If an engine is designed and built carefully and correctly, it needs almost no 'running-in' and very little 'warming-up', I know this from testing freshly built internally new engines on an engine dyno.

 

After 'running-in' the cams and solid lifters we change the oil and filter and give it death to ensure that the engine has been built correctly and to obtain a set of baseline power and torque figures before fine tuning fuelling and ignition, you can actually watch the figures rising as the piston rings begin to seal properly while holding the engine at peak power, it's all done and finished before the engine is even an hour old and the engine spends most of that hour at or near the redline.

 

If you watch F1 you'll notice that the team starts the engine and the driver then goes tearing off on a qualifier, no 'warming-up' needed, this is because the engine already has full oil and air pressure before it's even started.

the oil actually rarely gets up to full temp unless you are pushing on, in town driving they never get fully up to temp for the oil.

 

ever wondered why an MOT tester revs your car a fair bit before doing the gas test? iirc the diesels get a probe down the dip stick to test the temps for gasses.

that's because the engines are on a life support before pumping fluids thru and keeping everything hot

Surely the initial running in period these days advises against constant engine R&M running to prevent glazing of the bored.

I'd venture that it is a separate issue to then habitually giving the engine the beans from cold.

Question

Would you ever get Usain Bolt to run the 100 metres without thoroughly warming up and warming down? (And yes I realise that the human body and an internal combustion chamber are quite different!)

an F1 engine wouldn't start unless its hot. Fml

An f1 car is just a tiny bit different. It has heated oil and waterpumped through its veins for hours before they even start it. An f1 engine is sseized solid when cold and cannot even be turned over.

My turbo dosnt have any whistle when idling until it is half way warmed. Because the oil is thicker and puts more strain on moving parts.

For those of you who change your own oil. Look at the difference between hot oil draining out your sump and thick cold oil when you put it back in

Look after a car and it looks after you. Think about the temperatures involved and the different engine parts heating and expanding

That's all a myth I'm afraid and it simply isn't true. Pistons EXPAND when hot which is why any engine can seize if it overheats badly enough.

So does the rest of the engine. You maybe right. But I know which turns over easier. Hot engines

This will be arguable for loads of people. The method of going easy on an engine when cold got my last car (1.4 fiat stilo ) to 170.000 without fault .. so Im going to stick with it

Other end of the scale but... nitro rc engines . Anyone noticed how they are harder to pull over when they are cold but easier when they are ran and all warm .

Are people comparing F1 cars to a Fabia Vrs?

Lol.

Both have engines.disc Brakes all round. suspension. 4 wheels. Steering wheel. Spoilers. Gearboxes. Paint. Metal. Exhausts. Air filters. Pedals in the floor to change speeds . Drivers seats

Very similar really

Hey, you forgot the essential EGR delete!

all we can do is service them regularly and drive sensibly which makes one happy car owner.   :yes:
