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?

No. A little over the max fill line on the dipstick isnt going to hurt it. 1/8 of an inch overfilled or less is okay.
Usually if you don’t prefill the oil filter and only add what they say then sometimes it can be a little under. Its not a big deal.
Way too much and you risk damaging piston rings or flooding, but you really have to fill it to the point its spilling from the dipstick tube.
I usually fill mine right to the top and it hasn’t hurt the last sixteen cars I’ve had.
It sounds like you’re going through cars a lot faster than average. Are you sure it didn’t hurt them?
Hi Dave.
Oil is good, more oil is gooder.
