Hello.

I have a 1.3 multijet.
It was serviced 2 or 3 months ago, and had a new clutch
The 'change engine oil' light has just come on.

The problem is that the engine has starTed to smoke and when it does there is a significant drop in economy.

Does any one have any ideas what might be done, or shall I just take it to a garage and have it plugged in?

Thanks

Who serviced the car and gave it the oil change?

I recommend taking to Fiat dealership who will drain excess oil and reset the DPF oil degradation counter.
