OIL Quick question how much ml or liter of oil do i put in my civic

PAG oil is best if its totally empty 40 ml will do

Simple check first. Check your oil and make sure it is reading correctly on the dipstick. If it is low then add oil and watch everyday to see if the oil drops. If it is dropping quick enough to notice in a day or two then you have a leak somewhere an need to find that. A pressure test may need to be done as well to make sure oil pressure is high enough.

I have a 2012 Honda Civic sedan. In the manual it says 3.9 quarts. Th oil grade is 0W20

i have a dodge that does the same thing... when you find out let me know!!

There is no best gear box oil, only the correct gear oil.
Buy it from Honda and the parts guy will tell how much
you will need. I assume you have a manual transmission
so fill it till it's level with the fill hole. This is just a guess,
about 2 liters.

please specify what your problem is.

your vehicle is not equipped with a cvt transmission, so does not require cvt fluid. adding cvt fluid would cause a catastrophic failure. please reply and explain what problem you are actually experiencing.

3.7 quarts, not liters. Good luck and thanks for rating my response!

I saw this once where a guy took his car to one of those Quick Oilchange places and the kid put in new oil and forgot to take the old out first. Another thing to check is youre PCV Valve, if this is blocked it will increase your crank case pressure.

Checked brakes for possible wheel(s) dragging, as well as tire pressures up to max recommended pressure, and observe if tire wear unusual, signifying improper alignment? Any difference in engine oil grade used?
