1993 mercedes w124 diesel auto how to

trying a few different styles of ecodriving with my automatic 200D


last 3 fillups i tried with the tiniest amount of throttle i could give
steady throttle during uphills, only accelerate downhill if possible,
the result was 38.8 mpg (US), 6.1 L/100 km


next 3 fillups I will try more of a pulse and glide style with full throttle accelerations still doing my best to otherwise ecodrive the same way as last 3 fillups

(aparently I need to make 5 post before i can post pictures of her so we will wait for that)

cheers/Johan

Welcome to the forum. The mods never seem to mind if a real person, who is not marketing a product either, posts a few dummy posts just to get to the 5 post point. Feel free. I'd love to see your pictures.

I also wonder why it is that introductions must be checked by admin, seems a little strange when I can post these other forums, also a scangauge does nothing for this pure mechanical car, nowere to plug it in haha

Hello and welcome!!! Not sure if pulse and glide will work on your car. It usually works well with overmotorized cars and will have no effect on undermotorized cars, which is quite the case of your car.

To me you should accelerate strongly (80% of gas pedal, not flooring) between 2 and 3000rpm when you want to get your speed, and after that anticipate the maximum, use engine brake and not normal brakes (so decelerating earlier).
Your only potential for me is in reducing speed and anticipating.

Hi and thank you for the welcome

well that is sortof what i mean by "pulse and glide" give throttle to kickdown (no kickdown) wich is about 80% throttle and glide as long I can

she can really glide long way, being a slippery car, especially if there is slight downhill and this is what I use a lot already

right now I am reading on the forum: How to Eco-drive the VW PD TDI Diesel by COcyclist and I am guessing my car will have similar driving style.

the difference is that my car is automatic wich will make coasting in neutral very bad.
this will negate that part of fuel saving measures from that are possbile with manual transmission

spring change is on the meny since I am scraping a lot of places where I drive

it does, is atleast here in europe other side of the pond I think this engine is very unususal and non existent with automatic

some also say this is underpowered but in my opinion it is not I can drive way faster than speed limits and it is just on really rough hills i need full throttle to keep speed but for sure it is no racercar
