What is your RPM at 55 MPH

Hey all,

I have a 1977 Mercedes 280 SE US version. At 55 mph it revs at 3000 rpm in what I assume is 4th gear. Is this the same in your 280?

thats correct for your model.

in your transmission 4th gear is 1:1 and your axle is a 3.69

you can drive it at normal freeway speeds youre not gonna hurt it.

if euros have the same same ratio and last long on autobahns then you're ok

that said euro models have oil coolers yours doesnt.
