Filter on the Mazda 6 TS 2.0 litre? Driving back from South Wales to the Midlands ( 150 mile trip ) I noticed the DPF light flashing in the dash board. Got home then checked the oil level once cold. It was above the 'full' mark on the dipstick, but below an 'X' marked higher up. I have done just under 10k since the last service & unusually the 'oil level' has gone UP in the last 300 miles! When I dipped the oil, I noticed a distinct smell of Diesel fuel mixed in with the usual oil smell. Checked the owners hand book & it says take it to a Mazda service centre. Is it just a dealer problem or could it be done by any decent garage
