Windows warning is like the check engine light in your car, ignore till it starts being a problem lmao
For the record, if your check engine light is ever blinking, you need to immediately shut off your engine.
Shit is going very very wrong in your engine at that point, to the extent that it might cause an energetic catastrophic failure.
In my case it meant the cilinders were scrapping against the block with zero lube
It can mean a misfire too.
I had an old accord that basically lost a cylinder (blew a valve or something) but could still drive down the road with check engine blinking because that cylinder was “misfiring.”
It happened far away from home too. I drove several dozen miles with my unintentional 3 cylinder swap.
