I did an oil change. Thought the car took 4.4 quarts but it only takes 3.7 quarts. I poured in slightly under 4 quarts. The engine is a 1.5 in-line turbo (Honda Civic Si). It’s reading past the fill line slightly. How bad is it? Do I need to pour some out? What am I risking? What symptoms should I be looking for?

      I mean, you don’t HAVE to. But you can pour some oil into the filter to pre-fill it so the oil doesn’t have to pump so long for the air you cycle out of the system, but the amount of time that happens for is so small it basically doesn’t matter. If the oil filter is easy to access and faces upward (the solid part faces the floor and open part faces up) then I would do it, but I wouldn’t do it in any other circumstance just to not have oil spilling and making a mess everywhere.

      Youre not going to blow up the engine if you don’t. But it gives some people better peace of mind.

      I think it’s easier to fill a little extra after having turned on the engine.

      I just don’t pil change, it might show a little high, then you run the motor to cycle it through the system then it levels out. Good enough. A little less or extra doesn’t hurt anything.

      Source: not a mechanic, but I know a lot of them and I’ve never taken my personal vehicle in for a change in 25 years.
