How do I change the oil on a 2003 Volkswagen Passat?

Under the engine, remove the road pan/shield to access it

EVERY 3,000 WITH REGULAR 4,000 WITH SYTH BLEND 5-6 WITH FULL SYTH.

YOU HAVE TO REMOVE THE SPLASH SHIELD FROM BELOW THE ENGINE.AND PLACE THE RADIATOR SUPPORT PANEL IN THE SERVICE POSITION REMOVE POWER STEERING OIL COO;ER LINE FROM RADIATOR.YOU HAVE TO REMOVE THESE PARTS BEFORE YOU CAN GET TO THE COMPRESSOR BY LAW AND SAFETY.FIRST TAKE CAR TO DEALERSIP TO REMOVE ALL REFRIGERANT FROM AC SYSTEM BE REMOVING ANY COMPONENTS.

VW recommends synthetic oil only. There's a bulletin out warning about oil sludge if conventional oil is used. Stick with waht is recommended in your owner's manual.

bottom of the engine, u will need to remove the road shield under the engine to get at it.

It's a difficult job requiring the engine to be hoisted above the engine bay so the sump can be removed to gain access to other parts needed to be removed before doing the pump removal.

yes, and the crankcase is were oil is stored,like the oil pan,hope this helps.

WELL THAT YEAR DOSE NOT COME WITH 1.9 BUT ANY WAY IT SHOULD BE UNDER CAR NEAR RIGHT AXLE OR LEFT SOME TIMES

you should be using 5w-30 and change it every 3000 miles

if the car is diesel there is a paper type filter witch is under a black screw lid , right hand top of engine , you may have to remove top engine cover first
