For a change with filter, add 4.5 Quarts (don't forget to fill the filter). Run engine for a few minutes, allow the oil to drain back into the pan for another few minutes and recheck. It may take an additional 1/2 quart, or may not. The distance of the cross hash marks on the dipstick are typically the equivalent of 1 qt.
According to the 1997 Ford Aerostar Owner Guide ( 5W-30 ) With engine oil filter change : For the 3.0 liter V6 engine ( 4.5 U.S. quarts of 5W-30 engine oil ) For the 4.0 liter V6 engine ( 5.0 U.S. quarts of 5W-30 engine oil )
( there are 6 engine cylinders ) for the 1994 Ford Aerostar 3.0 liter V6 engine
On a 1993 Ford Aerostar , 4.0 liter V6 engine : With engine oil filter change : I ASSUME it is the same as the 4.0 in my 1995 Ford EXPLORER ( 4.7 litres / 5.0 U.S. quarts of 5W-30 engine oil )
In a 1990 Ford Aerostar : You either have the 3.0 liter V6 engine or the 4.0 liter V6 engine from the factory ( each size of engine has 6 engine cylinders )
On a 1994 Ford Aerostar , 3.0 liter V6 and 4.0 liter V6 : 3 - 6 2 - 5 1 - 4 front of Ford Aerostar
it needs approximately 16 quarts?
On a 1997 Ford Aerostar : On the 4.0 liter V6 engine the oil filter is on the passenger side of the engine On the 3.0 liter " Vulcan " V6 engine , it's on the drivers side of the engine
A 1995 Ford Aerostar either has a 3.0 liter or a 4.0 liter V6 engine ( The 3.0L has the engine oil filter on the drivers side of the engine and the 4.0L it is on the passenger side of the engine )
The 4.0 liter OHV , V6 engine in my 1995 Ford EXPLORER holds : With engine oil filter change : ( 4.7 litres / 5.0 U.S. quarts of 5W-30 engine oil ) I assume your Aerostar would be the same
In a 1993 Ford Aerostar : Either the 3.0 liter V6 or the 4.0 liter V6 ( the 3.0 liter V6 engine has the oil filter on the drivers side of the engine and the 4.0 liter V6 has the oil filter on the passenger side of the engine , just something I noticed and use to tell the difference at a glance )
According to the ( 1996 ) Ford Aerostar Owner Guide : With engine oil filter change : The 4.0 liter V6 engine takes : ( 5.0 U.S. quarts / 4.7 liters ) * 5W-30 is the PREFERRED oil
