Whining after oil change, fix? and oil level not reading right
So today i did an oil change on my 04 55, used mobil 1 0 40 oil and a stp filter.
right after the oil change, it started to whine, dosent go away when warm up, so it s different from the start up whine.
i searched a lot on the forum, seems like people are having this issue, some say its the oil, some say its the filter not being oem.
but i have not yet find a solution to this, any input?
also, i put 9 quats of oil in it but the computer only shows (three clicks on reset buttom) 7.4 quats. i drained the oil out from both the front and the rear sump.
is that normal? does the computer has to be reset?
