Accidentally reving 2017 Honda Civic Si to 7 rpms?

Ok so I've accidentally reved my Si to 7 rpms twice in the past day while coasting our of gear. Would that have done damage to my engine?

I'd worry more about the possible damage to my transmission while coasting out of gear than any damage to the engine. A 2017 should shut itself down before damaging the engine, at least my 2013 car will.

7000 rpms, and keep it under the redline.

  • Accidentally Took out the wrong engine cap in my Motorcycle while trying to drain the Engine Oil? My Motorcycle is a Honda XRM. I was trying to change engine oil but opened a different screw/cap just beside the engine oil drain.A 5 inch long spring and a rod with holes came out, i put it back the way i think it should be, then opened the Drain cap, drained the engine oil and filled it with new oil. But when i start the motorcycle it sounded like there's something loose moving inside the engine. What is the rod and spring that came out? Is it critical?
  • Accidentally put 89 octane instead of 87? I filled up my grandmas 2010 Honda Fit yesterday and I accidentally hit 89 octane instead of the regular 87 she puts in. Will this harm the engine? She does 100% city driving and has roughly 25,000kms on it if that helps. I should've said otherwise. It wasn't really accidental. The machine said "the grade selected is unavailable" so I pushed 89. Just clarifying.
  • Accidentally drove in 2nd gear on highway with automatic. Did I cause any damage to my car? I didn't get much sleep so this morning I was little out of it. On my 15 minute commute to work I accidentally put my automatic car in 2nd gear instead of drive. I drove on the highway for 5 minutes going 60. I didn't notice until I got to work and realized that's why my car felt a little different while driving. It's a 2002 Honda crv. Could I have caused any long term damage?
  • What are the technological improvements of a 2017 Honda Civic vs A 2006 Honda Civic? What are the various ways in which a 2017 Honda Civic is better than a 2006 Honda Civic of like-like model (say, EX vs. EX, LX vs. LX)? Plus, what is anticipated a couple of years out, like the 2020 model? A list of technological improvements would be great for me to decide if it is time to upgrade or keep the old car for a while still.
