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?
Close enough!
Edit for a recommendation to OP: if you plan to change the oil in the same car for the foreseeable future – get a transparent plastic pitcher and add a fill line mark for the oil on the outside with nail polish, in your case 3.7 quarts. I do this with my car and makes for a no brainier oil change.
If you also do this for the container you drain old oil into, you will be able to see if your car is starting to shown signs of oil consumption issues.
E.g. if you know you fill with 3.7qt, and you drain less than 3.7qt, you know you need to start checking the oil level every few fillups.
Generally a great idea. On this particular motor you’re more likely to find EXTRA volume as it has a known issue of gasoline flowing past the rings and actually increasing the volume of liquid in the crankcase.
That… seems… bad… but what do I know
There are rumors of a class action lawsuit.
