comment Does “slogging” an engine (open throttle at very low RPM) increase mechanical wear?
Ah I didn't see that question, don't think it came up in the Related questions list. Should I delete this, or leave it as is to serve as a link redirection?

comment How does cold, dry weather affect horsepower?
Interesting point. Though I think humidity is a different case, as it's in gaseous form then, not droplets of liquid.

Great, so it looks like I indeed have a free cold air intake! Would be fascinating to see if super cold temps, like -40C, continue to make a big performance improvement. I'll have to take my car to Antarctica to find out...

comment BMW 530xd e60 2008 diesel engine turns but won't start
Was there any resolution to this? Or is the car still not starting?

comment Do fast cars need to occasionally be driven fast?
True, ideally the engine should just be pushing out CO2 rather than soot. Might not always be the case with some engines, and those might benefit from a fiery soot-cleaning, but that then changes this question to "Do fast, poorly tuned cars need a good fanging?". Thanks for all the info!

comment Do fast cars need to occasionally be driven fast?
Ah fascinating. Ok so it makes sense that an engine running at operating temperature is a happy engine - no need to fang it. Last point - how about the exhaust? Some cars have monstrous exhaust pipes (GT-R) to handle the exhaust from a 600 BHP+ engine, and my understanding of back pressure says that you'd get carbon buildup from driving well below the max power output. Would this be the one case where an Italian Tuneup is helpful?

Ah right, so would that mean that harder driving doesn't require the radiator (fan) to work significantly harder?

Interesting, nice to have an anecdote. And yes, I'm realising that there isn't substantial objective knowledge about this. That forum unsurprisingly includes people advocating spirited driving for engine maintenance, but again, the bias is heavy! I'll let this question hang for a bit longer to see if we get some more objective responses.

comment Do fast cars need to occasionally be driven fast?
Good answer. I guess the uncertainty lies around the "operating temperature". Yes you have the cooling system temp, though for a given cooling system temp my understanding is that you could have a significant range of temps of the engine internals. I think it's possible that the engineers could design an engine for which the proper operating temperature, for internal carbon buildup prevention, is actually quite hot due to "spirited driving". I'm still learning about mechanics, but would that be reasonable?
