The same way you do on any other vehicle. Drain the oil, remove the filter, replace, refill.
I assume it is the same as the ( 1996 ) Mercury Villager : With engine oil filter change : ( 4.2 US. quarts of 5W-30 engine oil )
According to the 2000 Mercury Villager Owner Guide : With engine oil filter change the 3.3 litre V6 engine takes : ( 4.0 litres / 4.2 US. quarts of 5W-30 engine oil )
According to the 2001 Mercury Villager Owner Guide : For the 3.3 liter V6 engine : With engine oil filter change : ( 4.2 US. quarts of 5W-30 engine oil )
5W-30 is the preferred oil ( according to the 1996 Mercury Villager Owner Guide )
According to the ( 1996 ) Mercury Villager Owner Guide : With engine oil filter change : The 3.0L V6 engine takes ( 4.2 U.S. quarts / 5W-30 PREFERRED )
without oil filter 3.7 quarts with oil filter 4.2 quarts
I looked at the Mercury Villager Owner Guides from ( 1996 , 1999 , and 2002 ) With engine oil filter change : Each Owner Guide shows ( 4.2 U.S. quarts )
How do you change the thermostat in 1999 Mercury Villager
According to the 1996 Mercury Villager Owner Guide : With engine oil filter change : The 3.0 liter V6 engine takes : ( 4.2 U.S. quarts / 4.0 liters , 5W-30 preferred )
According to the 1998 Mercury Villager Owner Guide ( 5W-30 ) is the preferred oil
Check the Mercury Villager manual to see if there is a special procedure for cleaning the fuel injector. If not, you can purchase cleaner. You can also have the injectors cleaned by a mechanic or an oil change company.
