Hello guys, I asked myself some questions again, my neighbor driving school owner asked about how I save as much fuel as possible while driving! not cycling etc. ! I usually drive like this : 1 gear only starting, 2 gear up to 20, 3 to 30,4 to 40, from 51 5speed . And between the gears always FULL GAS until I am at the desired speed . For example 1 gear start , 2.speed directly pure and full throttle up to 25-30, 3.speed up to 35-40 full throttle , etc until I am in 5 gear or to the speed limit My neighbour and former driving instructor also told me, full throttle in the lower speed range does not matter, the engine gets only as much petrol as it needs at the speed, if I can quickly accelerate to the desired speed I can save. I am in the speed range between 700-2000 U/pm 50 km/h 1750 U/pm (according to Tacho 60 km/h Dacia Tachos go 10 km/h imprecise) If I have to brake I leave the gear in it, and then switch down when I am at idle speed level i.e. when I am at the I always turn off the engine at the traffic lights, where I know that I will be standing for more than 20 seconds. I always start red lights slowly so that I don’t have to start again, works quite well. Tire pressure I have at 2.7 bar front and back the same. At the time 175er R14 70R Firestone, Winterhawk tires. Now I ask myself the Dacia, with its low power output at E10 more gasoline than with E5? The rear windshield I usually only use heating for 1-2 minutes at the start of the car (depending on the weather) and switch on this KURZ only for 1 min in between times. How much liters of petrol consumes a 330W (RMS music equipment) system ? I do not always switch it to maximum, only if I am sometimes very good on it or drive with colleagues. Where is still fuel saving potential (except for the music) ? Thanks for reading!
