I just purchased a used 1997 XLT and I always do my own oil changes. Everything is fine except this: I put 5 quarts in and it is showing a quart low (manual says 5 qts but doesn't differentiate between V6's). I have owned two other explorers but both were the base 4.0 V6 motor. Does the SOHC require more oil? If not, why would my dipstick be off? For reference it does have the towing package so I don't know if they increased oil capacity as a part of that package (it never did on the base motor). I know that this is a general forum on oil but I am not getting any response on the ford site. If anyone knows the answer to this, I would be greatly appreciative. I don't want to be either a quart low or a quart too much. Thanks for your help.
