Hi, I have opened a thread over an L300 with alcoves here. As can be read there I bought the part. I have now also my first exit behind me. 3 days Lake Constance and back. Everything was wonderful. The consumption is now after 500km covered at 10.5 l. I have always tried to drive in as high aisles as possible. However, as soon as it vibrates I switched back into the smaller aisle. The L300 has 5 gears. I noticed that the L300 sees r is much worse to speed up than a normal car, it is understandable. If it makes sense to go up early into the next higher gear, or if you prefer to drive a little longer in a smaller gear. So I would like to have answered the question under the aspect of consumption, other aspects should first be considered secondary. I switched about this way: 1. gear up to 15km/h 2. gear up 15 to 35km/h 3. gear up 35 to 45km/h 4. gear up 45 to 75km/h 5. gear up 75 to 100km/h (fast If you have to push through the accelerator a little more in the higher gear to keep the same speed than in the next smaller gear, it can be that you still consume less fuel, because you drive in the higher gear at a low speed (at the same speed). My idea is that the fuel consumption depends on it as far as you can see. If this is the case, then it can make sense to switch to the next straight gear under the aspect of fuel consumption, even if you have to push the accelerator a little harder. Of course, it doesn’t necessarily make sense, but only if the effect of the stronger push through of the accelerator pedal is the effect of the lower pedal. Don’t compensate for the speed. Look forward to answers! Daniel
