So, I looked for an answer using the search feature without success. Basically, a while ago, I had a dealership change my oil, but they forgot to reset the FSS indicator. I have yet to reset it, and now it says I am about 4,800 miles late. At this point, the oil certainly has some miles on it, so soon it will need to be changed. But, if I reset the FSS indicator now, will it sense that my oil is old, or will it assume the oil is new, meaning the FSS will not show an accurate measure of when the oil needs to be changed. This is a difficult question to explain, but I can explain further if my question is confusing. Thanks in advance for anyone's help.
