Hello people First of all: Search used, nothing useful for me found! 😉 So. I have Audi80 B4 90hp built in 1992. So my problem is, it sucks and sucks. On average is bee just over 10 liters. My distance to the workplace is 35km. Of this are about 30km highway and highway. In Austria, so maximum 130km/h, i.e. about 3000 revolutions in 5 gear! 😉 I took over the car from my brother, and he meant the fuel consumption on good 8L. Ok. I’ve already read in part that the B4 needs a lot, but 10 liters? Notice everything that should reduce fuel consumption! Point 1: Tire pressure. Bite more, reduces rolling resistance, thus less fuel consumption. It was made. Point 2: Quickly switch to a higher gear. I always try to stay below 3000 curls, which works 90%. Point 3: Avoid unnecessary braking. It’s also done. Is there anything else I can do? Thx MFG
