Usually engine pre-heaters are either plug-in (you must have an electric power outlet at the parking spot), but there are also some Diesel-fired pre-heaters that burn a small amount of fuel to heat the cooling fluid. It would benefit from a quicker warm-up and smoothier idling right after start. In spite of the Diesel-fired ones also consuming fuel, they actually do benefit because the cold phase of the engine (which in a Diesel implies a higher fuel consumption) would become shorter.

Fuel line heating may also be a good option under extreme cold to avoid the Diesel fuel from jellying - and would also make it easier to run on pure vegetable oils

Next step. Changing driving style part 3. Installing a scangauge eco. If you see how much fuel you burn, you actually be more gentle with the trothle. And i must say. Superinvestment!!! Photo of the 1000km will be uploaded in a few hours.

I show you here, that i already beaten the manufacturers. Because the odo trip meter cant handle 1000km





Installed a scan gauge.

No pic of it yet.

Then i did something to the engine.
Chiptuning. But what is this?
I looked at the intercooler, damn, that thing is small
So lets trow some monney to it



I lowerd the AC fans until it is almost against the engine protection pan cover.
Then i placed an intercooler as big as possible:



Voila, This intercooler is almost 3 times bigger then the original. It is 2 times thicker and a bit more surface area.

The custum chip:
193hp and 407Nm.
That is 57hp and 89Nm more then stock
Hp is limited by the max airflow of the little VGA turbo, max torque is limited for the clutch and gearbox. The last thing we want is something to break down :P

When used, Engine heaters do reduce the engine warm-up time and increase miles or kilometers per tank even in warm weather.

[cRiPpLe_rOoStEr]

Did you replace the intercooler and chip-tuned the engine before hitting 1000km per tank?

[TimV]

After i was doing 1000km on one tank. I went with a bigger intercooler and a chiptuning. And that is giving me a bether fuel economie. ( more info will be added when i find the right data back)


@101Volts I will search for an engine and transmissionoil heater. But it needs to be powerd from the starterbattery/alternator. Because i do not have the possibility for an extension cord to plug in to the net.

[cRiPpLe_rOoStEr]

A transmission heater would be more recommended in an automatic transmission than in a manual.

[TimV]

The best i could get with the bigger intercooler and the custom chiptuning whas this:



I drove with that a little bit futher, and hit 1086 km when i filled it back up.
Exact 70l, witch gave me an average of 6.45 L/100km. That's 0,75l/100km les then the average of the fill ups before.

I don't know if the benefit coms from the better intercooler or from the chiptuning or from both, but there was a great benefit from my investment: 10,4%

Payback distance: 100 000km => 5,8 years
But this is the first run after the installation, and fuelprices are always rising, so it will be shorter

Hopefully...

Next mod, witch cost almost nothing:

Installing a boostgauge.
Before i shifted always at a given rpm and accelerating was on certain fuelconsumption numbers that the scangauge displays.



Now, at what amount of boost do i want to accelerate at anny gear?

I use 0,5 bar of boost, exept when i drive above 70km/h. Then i use 0,8-0,9 bar, otherwise it cost me 10km to go from 70km/h (=0,15-0,2 bar when driving a constant speed) to 100km/h (= 0,4bar when driving a constant speed).

Guess what fuel consumption i have now?

Both the intercooler and chip tuning might have resulted in this improvement, but the intercooler still seems to be the most likely.

[TimV]

With the bigger intercooler installed and then driving to an autotuner for the chip, the turbolag increased big time... That sucked, but the tuner did an amazing job and reduced the turbolag so much, that it was even a little bit faster spooling up then stock!

Superjob from those men.
If i wanted to pass a slow car on a one lane street, i always needed to downshift and let the turbo spool up before making my "move". Now i don't need to do that, driving in 4th gear @ 60km/h @ 2000rpm, just gun the throtle, wait like 0,2 seconds, and the car speeds up like crazy ass

But that aint driving economical :P
