Hello
I've been driving 2 full tanks with 60ml of acetone per tank with a conventional diesel and the result is clear: 10% savings!
would anyone else have tried it?
Fuel savings with acetone?

I'm trying to try too.
consumption with SP98 - 6,24 to 6,5L (7L max)
SP 95 - 6,5L
SP 95 + 60 ml acetone - 7,5L BUT having spent hours in traffic jams (bus strike in Marseille)
test still in progress ...
If you leave your car stationary for a while, add acetone because it is volatile (advice that André gave me).

Today 340km with a half full SP95 doped with acetone ...
A priori it works. When I am on the reserve, I will go to the gas pump and we will have the verdict of the conso.
Compared to the previous ones, it will still be necessary to take into account:
a) traffic jams in Marseille (bus strike for more than 40 days)
b) cooling temperatures.
But hey, we will see the results, and I will compare with Gegyx who has the same car as me (but his has no camouflage 'suburbs').

Hello
When you make babies, the Lamdda probe is not operational
unless you have a recent vehicle with an electrical heating system on the probe, but if you have a probe with a wire it takes 6 km in winter for it to become operational and when you are not on the probe consumption is exaggerated.
If you want to know how many km it takes for the probe to work disconect, roll and measure the km until the lamp (Engine Son) lights, this is the indication that the engine has stopped working on its preprogram and that the probe is not operational.

The lamba probe and the windshield were changed yesterday ...
So a priori it works. The approximation I gave yesterday is given from the indications of my fuel gauge, which is on the whole fairly reliable. However, you must wait for the pump to fill up to measure the amount of fuel used.
So for the moment it is working no worse, remains to go to the end ...

Hello
I found your advice to be finally fixed.
I drove yesterday, 14 km, with the probe plug disconnected.
No indicator lights on the dashboard.
The Audi Group obviously did not plan to light an indicator on the Skoda, Félicia special, from 1995…
When the lambda probe is disconnected, I found no difference in driving or engine noise compared to usual; I suppose there will be over-consumption; the computer does not receive a voltage from the probe, it must include 0 volts?
After many kms, the probe must be changed; if it is out of service (broken, because worn), what type of fault does it appear, then? (What were your symptoms Former Oceano?) A colleague told me that it was slow hiccups; so it’s not the same behavior as when it’s unplugged. So a tension must be present, and can be the maximum, because the failures indicate a lack of gasoline, the calculator believing to see on its probe a mixture too rich.
Is this how it works?
You say that by electrically heating the probe, it is deceived (tricked), and begins to regulate by saving consumption?
If I unplug the probe (making only 5 km journeys), and after 1 km, I put XNUMX volt on the computer socket, do you think I would save fuel? but there would be faults, if the different parameters are not adequate (untranslatable ), and the engine is cold? Is it possible to do so? Is there a risk of imbalance or deterioration for the computer?
On the probe there are 3 wires; I suppose the -, the + 12v, and the return voltage from 0 to 1,1volt? is that how it works?
Thank you

Hello,
I'm just going to brush the probe quickly because it would take a long time to say everything.
Normally it generates a wavy dc signal at 0,1 volts high oxygen level so lean mixture and 0,9 volts low level oxygen rich mixture, if you measure with an oscilloscope it goes between 0,35 and 0,60, XNUMX volts approximately it just dances,
Do not try to replace the signal by a simple adjustable source you will get nowhere, it is the internal voltage of the computer which is opposed to this signal which must be modified, and again ... the probe to be operational. the engine should not be idling, the exhaust should be hot, it should be ventilated outside with air,
If you unplug it your engine runs as well, even slightly better since richer ratio of 12 instead of 14,7
with a ratio of 12 we get more power on the engine
maximum power is at the expense of consumption.
this is the situation when we make short trips.
What changes probe c is leaded petrol (example of 100LL)
it takes a 500km with this fuel and the probe is dirty,
It is not necessary to clean it if you sauce it in a Kaput solvent.
another problem the electrical connection must be first class we speak of millivolts.
If you use most of the time your vehicle in town, the probe does not last long, and it is not worth changing it, unless you intend to make the long journey,
change it is check the consumption you will see the difference.
Another 6 months in town is like an old probe.
