New owner of a 65 Thunderbird convertible. I recently changed the oil and filter with 6 quarts per the supplied owners manual. I noted the oil appears to be maybe a quart above the full mark and I was wondering if the dipstick might be wrong?
The picture shows the length 22.5 inches from the base of the cap (not including the height of the cone). Could this be the wrong one for the 390 or is the manual wrong and I overfilled it? Thanks in advance...
