Accidental rev in freezing weather on cold start :-/

[Jenson]

Hi,

So I jump in the car this morning and it's about 30 degrees outside. Start up the engine and it idles for maybe 10 secs, then instead of pressing the brake pedal, I press the gas. Before I realized what I did the engine revved up to around 4500 rpm :-/

I know the engine is not toast, but is this likely to cause any long term damage as a one-off?

Also, what damage/harm could this potentially do to the engine and how does that actually manifest? Is it just likely to cause potential issues at like 120k miles or something when the engine is much older?

to BITOG. Although not ideal and shouldn't be repeated I'm sure it's fine.
People do far worse to cars intentionally.

That just causes faster wear unless you have too thick of oil.

 

[Pelican]

Nothing to worry especially if using 0W....

 

[ka9mnx]

No harm. Are you going to own the vehicle at 120k?

 

[Pinoak]

For sure. You will have to change your flux capacitor soon.
Haha jk. Don't worry

 

[tmorris1]

Did do a thing to it. 30 isn't cold and oil was flowing within 10 secs.

 

[billt460]

It is generally accepted fact that most engine wear occurs at startup. You most likely induced a bit more of it. Seeing as you can't undo it, I wouldn't worry about it.

Time to trade it in

If you had started the car with your foot on the gas, and revved it up to 4500 RPM immediately, then I might be concerned about it, but after 10 seconds of running, it's a certainty that the oil was everywhere it needed to be, and did its job.

... that is, unless there was some other issue in the engine that was preventing the oil from pumping/flowing. If that was the case, however, then the accidental 4500 RPM rev is the least of your problems.


What car / engine are we talking about, BTW? You didn't mention.

Here's how I look at it: Odds are the lot boy at the dealership where the car was bought drove that car long before you even saw it. He more than likely floored it cold, might have even done a hole-shot moving at the dealership, probably more than once. Secondly, you can't turn the hands of time back on what you did. So I'd find something more important to make myself sick over.

 

[PWMDMD]

OMG....

 

[Schmoe]

10 secs?? No worries. That was enough time to get oil moving. Plus, there was probably still a sheen of oil coating the internals from the last time you drove it.

 

[slacktide_bitog]

No damage will occur. There is a rev limiter to prevent you from spinning the engine fast enough to cause any damage

If you ever saw what rental cars go through trying to get out of a snowed in parking lot after a storm what happened to your car is nothing.

+1 ... Not much to worry about, just don't make it a habit though.

 

[RF Overlord]

+another for what SirTanon said. On the list of things to be concerned about today, it's WAY down there.

The oil filter differential probably put a hole in the media. Maybe, among us worrying types anyway. ... If a Fram Ultra was there, they don't tear (rhymes!). If a paper element filter was in place, please don't race. (kinda like a rap song at this point....)

 

[LeakySeals]

What weight oil are you using? What filter?

 

[Jenson]

Might have been more like 5 seconds...
