Hi, i noticed in the last day or 2 that my rpms have gone up a few hundred..

at 55 i could be between 1400-1600 rpm depending on incline etc.

now at 55 im at 1800rpm-2000

I got the car checked out today and replaced the clutch master cylinder, the mechanic told me my clutch wasnt slipping but it was worn a bit and if i was nice i could fetch a few months more out of it.

i got a 92 civic lx 5spd 1.5l d15b7 non-vtec...i was averaging 33mph at the 1400-1600 rpm..im wondering if its gonna drop mph now, i was already a bit sad that i wasnt fetching the advertised 37-40mpg for the car...maybe its just old..

i was wanting to know if 2k rpm at 55-60mph was okay or not and what other civics (d-series) were running rpm wise at those speeds. thanks
