I am watching this subject carefully while I am writing friends, I read what is written & nbsp; diesel & nbsp; performance (bp, po, opet, total, shell, tp) & nbsp; performance etc. I made many trials, I made 600 km with 125tl fuel, I was careful while using sudden departures, I did not change gears suddenly, did not change gears. I shook in vain according to the place, I went down in gear, I gave my broken ear to the sound of the engine, adjusted it accordingly, I set it myself max 90 I went 100 km speed, my average was 80, I got the best performance in the fuel of tp I recommend (100km in city 500km out of town)
