What kind of oil is recommended for the 1996 for an oil change?
For a 1996 Ford THUNDERBIRD , 3.8 liter V6 and 4.6 liter V8 :
( 5W-30 is the PREFERRED engine oil viscosity according to the Owner Guide )
* 5.3 U.S. quarts / 5.0 liters of 5W-30 engine oil with engine oil filter change ( both engines ) the dipstick is used to determine the fill requirement
If it's a newer year Focus I'd say it's letting you know it's gone longer than the recommended mileage to change the oil. My BMW assumes 6000 miles is the preferred mileage to change the oil, but its recommended to change the oil sooner in my opinion. Clean oil makes engines last longer in the long run.
