Where is your oil filter on your 1999 mercury mystique?

Answer 1

I am pretty sure it is underneath the car passenger side. It is a bigger sized filter.

EDIT:

4 cylinder engine has the filter at the rear of the engine on the passenger side.

On V-6 cars, the filter is at the front of the engine. When you drain the oil on the v-6 wrap the rear exhaust pipe near the drain plug with aluminum foil. It is almost impossible to avoid getting oil on it, and this will save you some headache.

Both are best accessed from under the car and both are a bit of a pain for the first timer, but after a few tries it gets easy to do yourself.

Despite their reputation on the internet, these are great cars to own. Be aggressive with the automatic transmission maintenance and you'll be happy for 200,000 miles like I have been.
