Tank? Engine oil is held in the crankcase except for "dry sump" engines, which aren't really dry, it's just that for them, the oil drains back into a sump and no oil is stored in the crankcase. But for your Mercury and almost every other street-legal, production automobile, the oil is mostly in the oil pan, which is that metal cover that's at the bottom of the engine. It also has a drain plug which you can remove to drain the oil. If you look around, you'll find the oil filter which should be replaced every time you change the oil. If you haven't done it before, it might be good to get a little experience by watching someone change the oil for you.

Hi, I work for Fram. Your Mystique oil filter is a TG8316 if it is a four cylinder engine, it will be a XG2 if it is a six cylinder engine. If you have further questions, i can be reached at jay.buckley@honeywell.com
According to the 1999 Mercury Mystique Owner Guide : With engine oil filter change : The 2.0 litre four cylinder engine takes ( 4.5 U.S. quarts of 5W-30 ) The 2.5 litre V6 engine takes ( 5.8 U.S. quarts of 5W-30 )
The timing marks are on the crank pulley and oil pan. You have to line them up and also line your cams up.
ON a '98 Mystique it's on engine between engine and radiator.It has a "T" shaped handle on top.

The oil filter on a 1998 Mercury Mystique is changed by lifting the vehicle up on ramps, placing a drain pan under the filter, and unscrewing it. A new filter is then put in place and torqued down.
