SLK/R170: 1997 slk 230 fuel consumoption
I would like to ask for help as my 1997 SLK230 is in high fuel consumption.
Some of the slk owner ask me to use the W mode rather than S mode, then now i use the S mode in 100% city use is around 15.5mpg. it is very high.
So i would like to ask if anyone can give me some suggestions to fix this problem.
Thanks a lot.
