Diesel consumption

I was confined to the engine room of an elderly Thames sailing Barge some years back. The fuel tank was dodgy so we rigged up a pipe-and-funnel system to keep the old Gardner 6 pot running. I was surprised at how much had to be run into the old girl to keep her on 'steady' revolutions. 600 RPM was the norm & it was certainly several litres a minute.
Personally I hate leaving any machine on tick-over as I regard this as a waste & not good for any engine & you'll save several pounds in a day if you do pull the stop button of use the switched solenoid!

You'll also destroy any engine with a turbocharger. A turbo continues to spin at high RPM for several minutes after the engine spools down, cutting the engine also cuts the oil supply to said aforementioned turbo.

Leave the thing ticking over for a few minutes, be mechanically sympathetic.

A turbo will only keep spinning for minutes if you turn off the engine while at full boost.
As long as you let it run at lower throttle for a minute or two before shutting off there's really no reason to park it and idle for minutes...

Entirely correct, but engines are increasingly at or near to full boost a lot of the time. My tractor is boosting hauling a trailer from the field next to the yard, thanks to emissions related engine mapping.

My car boosts at anything over 1/8th throttle, which means constantly.

I think it's safer to assume that a machine is on boost any time I use it, which means letting it cool off before I settle myself in the chair for the evening.

Idiling a turbo charged engine before shut down is not, to allow the turbo to slow down, but to allow the turbo to cool.
Heres a piece on it copied from the web.
Idle your engine for a while before shutdown to cool it down.

What you’re trying to avoid here is the typical interstate deceleration and stop for refueling, or similar behavior where the engine has been producing a decent amount of power, and the engine is then rather quickly shut down. The turbo is not only lubricated with engine oil, but the oil is a principal cooling medium, just as it is for the engine. Engine exhaust at idle is much cooler, so idling the engine means cooler exhaust and oil flowing through the turbocharger bearing housing helps remove the heat build-up.

When this is not done it causes a hot shutdown, where the turbine housing acts as a heat sink that gives up its heat to all the surrounding components. The exhaust heat that travels from the turbine housing to the turbocharger bearing housing literally cooks the engine oil, which is now trapped since the engine is shut off. The cooked oil forms a hard coke deposit that, over time, builds up like cholesterol in arteries. This can have a very detrimental effect, plugging up internal oil passages and reducing the oil supply to critical areas of the turbocharger.

Allowing the engine to idle for two minutes may seem like an eternity once you are where you’re going. But if you’ve been running the engine hard, and you know you plan to stop shortly, you can anticipate this and intentionally go easy on it for three to five minutes prior to shutting it down. Then you can rationalize more like a one minute idle before engine shutdown. All it takes is some common sense and turbo awareness

Most, almost all modern cars and trucks, are now fitted as standard with automatic stop/start systems. Perhaps you have missed this phenominon which has become universal over the last five years or so? It's even fitted to the milk tankers that collect here and they automatically restart when vacuum is needed to suck the milk in from the tank.

Completely and utterly irrelevant. Auto stop/start is fitted for emissions reduction purposes, completely at the expense of wear and tear to the mechanical subsystems.

I disable mine on every start up!... but a car coming up to a traffic lights is idling and cooling the turbo before it stops, not many cars /lorries are under full load and then stopping dead.

I had on my escort rs turbo several years ago a Clifford alarm. I think 600 series. I programmed it so when I turned the key off and got out it remained running for 2 minutes to cool the turbo. It was also programmed so if you pressed and held the unlock button it would start the car to warm
It up on a cold morning. If you pulled the handle it would stop the car as it thought it was being stolen. Awesome alarm, why this can’t be programmed into tractors now I don’t know. I’m sure it can be just not needed perhaps. Remember, manufactures don’t want their machine to last for ever other wise they would never sell new ones. Turbos are a replacement part. They make money from selling them.
