So the handbook lists the oil capacity of my Subaru as 4 litres. I changed it myself for the first time this morning. Put a measured 4 litres in and the dipstick shows about a third litre low. Is the dipstick off or does the listed capacity not include the filter? I'm going to change the oil on the F150 now for the first time, so I'll measure the oil again and see what happens. The pickup has the 4.6 and the filter is at an angle that's sure to cause a mess when it comes off, but this baby has a factory installed drip tray under it. Good thinking,Ford!
