Hi all,

I have a 2010 Ford Fiesta MK7 1.4L petrol with 107,000km (67,000miles) and it recently started consuming some oil. I have owned the car since new and it was always serviced every 10,000km (6,000miles) using Ford genuine parts and oil (5w30) as I buy them myself.

I noticed the issue in the last service when the car was almost on the MIN mark and the plugs were brown and they were last changed 20,000km before, so they're not old. There is no visible oil leak as the engine bay is clear and no oil drops underneath the car, and its not the first time the car has spent 2 or 3 days parked in the garage in the same spot. No visible blue smoke and the car drives just like new, no hesitation under acceleration or anything and idles just fine. Coolant water is crystal clear (changed 5,000km ago and was clear as well), no visible milky stuff with the oil cap. Exhaust is clean and recently passed MOT and emissions were normal.

After the last service at 100k km, for the first 5k km it didn't seem to consume any oil at all, however in the 2k after it went from MAX to almost MIN sign and I topped it up with 2L of oil.

 

From what can I start to check what may be wrong? Opening the engine is the last thing I would want to do...

Do these cars come with a PCV valve? 

Could it be something with the Oil Separator? 

I do a lot of short journeys, 10 to 20km most of the time, if this makes a difference.

Short journeys will wear the engine out quicker. It doesn't give the oil enough time to get to temperature and lubricate everything properly. You could be burning oil due to bad piston rings. Are you noticing any blue/greyish smoke out the exhaust?
