very valid point, my consumption increased from 7.5 L/100 KM to 8.9.
The only problem RON 95 is triple the price of RON 92, but frankly i am not willing to screw my engine for whatever reason, i am going back to RON 95.
but on a technical side note, shouldn't the sensor adjust the timing so this knocking sound or pinking or detonation don't happen?! its really not happening unless i am on D and kicking down or going uphill.
You don't say where you are? , if your county has 92 ron as standard, and judging by the price hike for 95 ron im gussing it does, then your car should run on it unless its an import?
Lots of countries have lower than 95,even the Americans (although some countries measure it differently)
Anyway your knock sensor should as you say retard the timing etc to stop the knocking, yours may not as they may not have mapped your car for a market with fuel that low and the car may not be able to retard the timing enough to compensate for the 92 fuel, because it was never destined for that market when the build sheet was filled out
It should be easy enough to find a solution and at a third the price for 92 ron it sound like its well worth it
But as others said, don't drive it on 92 till you have it running on it without knocking
