Hi all: I posted this question in the oil forum, did a search, and found this thread so thought I would revive this thread with a similar question. I was unaware of rev limiters till reading this....
Here is what happened...
After a thorough cleaning of my 2015 Corolla yesterday, another family member put in the cleaned plastic floor mat today. Apparently, it was placed on top of the gas pedal thereby pushing on it, because when it was started cold (in the garage at about 30F), the car really roared with a big puff of smoke. The car drives fine and I think things are OK but it still bothers me. I don't know how high the rpm's went but it was pretty loud. In my favor, I think, were:
1. car had been started yesterday so engine surfaces were recently wetted with oil
2. I've been using recommended Toyota 0-20W synthetic oil which I think would be really thin at cold temperature and flow and protect quickly
3. car has 30k miles on so is probably completely broken in
4. car was shut down within 3 seconds or so
5. car is well maintained, never abused and I'm sure this won't happen again!
I'm probably worried for nothing, but buy new cars for life and take care of them mechanically and cosmetically for 20+ years so things like this annoy me when they happen. After reading this thread, I don't know if the 2015 Corolla has a rev limiter and if so, does that mean hitting dangerous red line was not achieved? Someone here mentioned approaching rev limiter levels is worse at idle (which the car obviously was) opposed to under load going down a road.
