Warming up your engine?

[kensilver]

Do we let our V12 warm up before starting? Or drive off straight away? Back in the old days I was taught to let the car idle for a minute to let the oil flow through the pump etc.

Has that theory changed? What does everyone else do?

Accelerator flat to the floor. Then crank the car. Car won'tstart with aaccelerator fully depressed, but oil pump engaged.
Remember to stop turning the car over BEFORE releasing the accelerator.

Won't that flood the bore with petrol which will dilute/wash away the oil? (Correct me if I'm wrong, my engineering edumacation stopped decades ago when they started putting computers up front).

No.

There's a logic in the start cycle which recognises that the throttle is fully open so it turns the engine over without running the fuel pump or energising the spark plugs, ie just the oil pump runs. It's in the manual (under the long term storage section).

That's for extended storage 6 months and longer. I doubt whether it's a good idea to do it daily.

My original question was directed to V12's because I wondered whether the extra cylinders required a different starting or warming procedure, but it seems not. Tonight I started up and immediately backed out of the garage with only a slith twinge of anxiousness - which will probably diasppear after a few years...
