I'm still trying to learn this Taurus that I bought 4 months ago, and I have a question. It is a '99 with the 3.0 ohv engine. Both the owner's manual and a Haynes manual say that the oil capacity with a filter change is 4 1/2 quarts. When I put that much in, though, the oil is at the very bottom of the hashed marked area of the dipstick. When I add another half quart, it brings it up to a little above halfway on the hashed marks. That would seem to mean that this car is taking 5 1/2 quarts to bring it to the top of the acceptable line on the dipstick. I like to keep my cars full, but I don't want to overfill either. So, can somebody tell me what's going on? How much do you use in your Taurus's? Did they put larger oil pans on any of them? Should I suspect that this is not the correct dip stick? What? Thanks.
