Are we really worried about engines wearing out? - PeachParts Mercedes-Benz Forum

One of the most hotly debated topics on this board has to do with oil. Oil changing methods, oil changing intervals, oil types, oil filters, oil viscosities, and so on. Do a search with the keyword "oil" and prepare for a lifetime's worth of reading.

Why?

Are we all that worried about our engines dying an early death? If we change the oil every 3-6000 miles or so, and use a good quality (dino or synth) oil and filter combo, will any of us face premature engine failure? Will it make any difference if you use a topsider or drain method? Will increasing your interval from 4000 to 4500 miles make the difference that leads to a premature engine failure or early wear?

Now, really long intervals do make a difference, and that's not what I'm talking about. I'm talking about realistic (less than 6,000 miles or so) intervals.

For those of us with late model Mercedes', I think the last thing that will break the bank is going to be any kind of lubricated part repair. I think that the lubricated bits in my engine will be going strong long after many electrical parts and transmissions have given out. I see things like O2 sensors, MAS's and such becoming failure items. Wiring harnesses and engine accessories will crumble/wear long before rings or pistons give out.

What about ACC/AC systems? They have all kind of bits that can wear/break, and probably will long before any engine parts do. Expensive parts they can be, too.

I see lots of 10-15 year old MB's that need suspension work, but the engine is strong and tight. Bushings, shocks, etc. wear out faster than a Mercedes engine.

There was a recent thread where someone got uptight about the fact that using a Topsider might not get the last few cc's of engine oil out. Cripes! Just change the bloody oil and filter using the method you like best, and use a reasonable interval. Stop saving for engines and start saving for pretty much everything else on the car.

A stranger happening onto the board would think that we're all paranoid about early engine wear!
