I made a rookie mistake and when installing the new oil filter I forgot to take the washer off the old filter. I completed the oil change and topped it up. Wondering how much oil I will lose by taking off the filter to install the washer?
i assume you have taken care of the problem. If not you have oil all over a lot of things because two seals between the filter and block is more than likly to leak. You will not loose too much oil from removing the filter to correct
