Should be 5W-20, which is typical for Ford products with a gasoline engine.
According to the 2006 Ford Expedition and Ford F-150 Owner Guides ( 5W-20 ) * with engine oil filter change , 7.0 U.S. quarts / 6.6 litres of 5W-20 engine oil is used in the 5.4 , 3V engine used in the 2006 Ford Expedition / Ford F-150
10 w 30
I would recommend at least Grade 8, just to make sure.
In a 1995 Ford Taurus : ( 5W-30 is the PREFERRED engine oil for the 3.0 and 3.8 )
regular unleaded , 87 octane
For a 2001 Ford E-150 : The gasoline engines use ( " regular " unleaded , 87 octane )
5 W - 30 is the preferred oil - that's what I've always used in my 1995 Explorer XLT
The stock horsepower for a Ford 429 engine is 320. The Ford 429 engine was used on Ford vehicles made in the 1950s and 1960s.
Mazda used the ford ranger body but used the Mazda engine.
If the 4.6 liter is in a Ford Expedition it should be ( 6 quarts ) with engine oil filter change
For older vehicles, 10W30 or 10W40 should be used in a hot climate. A lighter viscosity oil, such as 5W30, should be used in newer vehicles.?æ
