There have been many discussions about the pros/cons of using different specifications of oils.
I would personally recommend using the oil specified by Ford for the Puma! These specifications are:
1. Ford/Motorcraft Formula E SAE 5W-30 engine oil
2. Other manufacturers SAE 5W-30 engine oil meeting the WSS-M2C913-A or WSS-M2C912-A1
3. SAE 5W-30, SAE 10W-40 or SAE 5W-40 all meeting the requirements of ACEA A1/B1 or ACEA A3/B3
*This list is in priority order and I would only recommend 1 & 2 as other oils in 3 may result in longer cranking periods, reduced engine performance, reduced fuel economy, and increased emission levels.
These specifications are directly from the Owners hand book and may have been updated.
