Those of you with 4-speeds, do you ever do this?

I have a 4 speed manual in my 230CE and often times while in 4th gear I try shifting into 5th but DUH, there is no 5th! I think I'll have to search around for 5 speed as I find myself doing this far too often.
Anyone else willing to admit doing this?

Yup, did it all the time. Revs too high for my tastes on the highway.

Brian , you just need to make sure your engine compartment is well sound proofed.... these engines are very well suited to the gear ratios provided by the factory...
In fact, I will bet that most people are lugging their engines 90 percent of the time... a very bad thing.... I am going by when I ' want ' to shift compared to the little marks on my speedometer.... indicators of ' speed to shift'.... feels and sounds like it is going to explode when I actually go all the way to them....
Or maybe someone changed out my third member to the wrong numbers... LOL

Why is lugging a diesel a bad thing-enlighten me(I always heard that mileage/efficiency on a diesel was better at low rpms-not that a good italian tuneup hurts once in a while)

Yep, I did that in my Euro car for a half million miles, but it may be geared a little lower than a US car.

Lugging is a bad thing for ANY engine. You are imposing incredibly high pressures on the bearings, and crankshaft. It will flatten crankshafts, add extra wear to the thrust side of pistons and cylinders and it's just un healthy.

Have a great day,

Bullwinkle....
Think of it this way... the difference in wrench pressure needed to get the same pulldown on a fine thread bolt compared to a coarse thread.... you are lugging when you are not using the proper number of turns of the engine for the amount of load you are needing to deal with...
And this winds up ( pun ) being bad on the internal parts of the engine ...
