Hi everyone, I am a new owner of an 05 Mustang. I am glad that I've grabbed the vehicle at a cool price, and I am fine with those minor body dents and scratches... I have got a quick question though. Assuming that I have to change oil and replace filters (which is fine for me), I checked the oil level and the dipstick was black as hell! I assume the filter is also clogged. So what would tyou recommend me to do, is there a sort of additive I may put in there along with new oil and a new filter... Or just change oil and filter, give it some 1-2K and then change oil again? What are your thoughts at this point?
