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 wouldn’t worry about it. Even on brand new cars, there are plenty where losing (burning) a quart of oil between changes is “within specifications.” The engine is likely going to burn a little bit of oil just because, and you’ll be lower again soon enough.
