Oil amount
How much oil will I need to change the engine oil and filter on a 2007 Ford Mondeo MKIV 2.5 20-valve straight-five turbo? The Haynes manual mentions the 2.5, but doesn’t say if it is the five-cylinder or V6 engine.
Your Mondeo with engine code HUBA should take 5.8 litres of 5W-30 synthetic oil. I did find a slight discrepancy as Autodata and the Ford manual say 5.8 litres, but two of the oil companies stipulate a capacity of 6.4 litres. Given this, I would fill it with 5.8 litres, then check the level on the dipstick and top up if necessary.
