Hi,
My 1.25l 16V Zetec Fiesta (1998) is now burning about 2 litres of oil every
1000 miles. I'm using 5w30 semi-synthetic but it's getting rather expensive to put in this much all the time!The manual says I could use 10w40 so I am considering using "High Mileage" Castrol GTX Magnatec 10w40. Does anyone think this is a silly idea? The car runs fine and passed its MOT emissions test easily a few weeks ago. I am sure oil is not leaking anywhere as I park the car in my garage which has a clean floor (it's new-build house) and the floor is still clean, as is the outside of the engine.
Do people think it is the oil control rings on the pistons or could something else be making me lose this much oil?
Tony
