Hello,
I own a 1994 petrol 4 cylinder engine, iron block, with mono-injection.
Is it necessary to warm it up before driving, or high revs?
Thanks.
Well, but I'm still seeking an answer to my original question related to the wear and tear it can potentially cause, if any.
It's going to eventually cause wear, how much is anybody's guess. You don't need to let it idle up to operating temperature, but you also don't want to start and drive it right away. Pumping cold, viscous oil to the top of the engine takes a little bit of time. The more RPMs you put the engine through before it is lubricated effectively, the more wear you're going to cause, plain and simple. Waiting 60 seconds to drive is probably fine.
Revving high when not at operating temperature will cause long term wear because the engine specs for clearance are set at operating temperature. Parts that are thousandths of an inch too loose can wiggle ever so slightly, that means pieces wear against other pieces prematurely. It's not overnight, but it eventually adds up.
Thank you
Is it necessary to warm it up before driving,
No, it is not neccessary.
No. Fuel injected engines don't really need warming up. They are able to compensate for temperature.
Just make sure you have full oil pressure.
Thank you for the reply @mmj
What about for wear and tear when it's cold, in a situation where it's revved high for a few seconds, considering it's 10w40 ?
I don't know what you mean. Can you be more specific?
Considering 10w40 is not the thinnest of oils, it takes a few seconds I assume to reach the entire engine parts.
Imagine a cold morning after 15 days the car parked, turns on and is immediately revved up.
Will there be damage or a lot of wear a tear from this?
why are you revving it?
The reasons could be infinite as far as I'm aware. I see people doing that, maybe because they don't have the patience to wait.
I'm not going to list every possible reason, I'm just wondering about the possible damage of what I described above, can potentially cause.
Well don't rev it. Just drive normally.
Well, but I'm still seeking an answer to my original question related to the wear and tear it can potentially cause, if any.
Just wait like 1-2 minutes or till the revs settle in your tachometer you will want to let the gaskets expand.

Is said engine, located in a vehicle?
As far as I know it's still in there 😆 😆 😆
