Average fuel range on C class estate s205 220d

Quite.....and all 4 drive shafts are still being spun as they are fixed to the wheels....so whether they are being spun by the gearbox or just by the wheels their motion still comes from energy from the engine.

He OM642 in my 212 warms up really fast...as fast as our petrol A Class and much faster than my old ALFA....the gauge reaches 90 and the heating gets hot a good couple of miles earlier even at this time of year.

Your HVAC may contain an electrical heater, so you can't necessarily go by what's coming out of the vents. The coolant will also heat up much faster than the actual engine since it's only circulating around the block(s) until the thermostat opens. Oil temperature is a much better indication of engine temperature, and that always lags far behind.

True....and no oil temp gauge on my car.....but the coolant still warms up fast for a derv compared to other ones i drive. My company Ranger and DMax take much longer.

I think oil temp. gauges are pretty much a thing of the past now, although I imagine some 'performance' cars can display the info. The VW I had before the Vito had oil temp. - I did like knowing when the engine was fully warmed up.

My 3 Series only has an oil temperature gauge; no water temperature gauge. Fooled me when I first got it..

Our works Astra vans dont have either!!....the first time you know its overheating is when the warning light comes on!!!

But even in 2WD you are permanently carrying around extra weight compared to a 2WD version of the same vehicle, which affects the economy.

As above.

A quick Google search shows that the 4Matic S205 weighs around 250 kg more than the 2WD S205 (varied by engine type, etc). That's a 15-17% increase in weight, and it has to affect fuel consumption, regardless of whether the 4WD is being used or not.

Gauges on high performance cars are now decorative.... there's no need for them.

Cars are fully computerised now and will let you know if something is wrong or if any action is needed. Apart from the fuel gauge, which, these days is a digital representation anyway.

Unlike aircraft pilots, who have plenty of time to bury their heads in the cockpit and study the gauges, car drivers are meant to keep their eyes on the road at all times.

The less reasons you have to look at your dashboard, the safer you are driving. Now don't get me started about touchscreen infotainment systems.......

Be nice to know if the oils hot before you can the crap out of it though....no computer warning tells you that!!! As said above...just because the coolant is up to temp does not mean the oil is.....

Agreed.

Also, you can see the oil temp via a digital gauge on Torque and similar apps using OBDIi Bluetooth dongle, or the car could be programmed to let you know once the engine oil has reached operating temperature if the manufacturer thought it was important enough.
