The service interval in Europe is 20,000 km - Ford AU decided in their wisdom to make it the same as the Falcon.

As the Mondeo diesel has a Peugeot engine, I follow their recommendation and use a Total oil - Quartz Ineo ECS, which meets Peugeot requirements. It's a mid-SAPS oil meeting ACEA C2.

The Nulon oil is a C3 oil, which may provide better engine protection but will increase fuel consumption slightly compared to C2 or the Ford spec oil.

I doubt that it really matters which oil you use, but safest to use a C2 oil if you're concerned about DPF failure. Penrite make one, but I'm not sure about Nulon.

30% off Penrite at Repco in NZ this weekend.

Total Oils not readily available in Australia unless you're in Victoria (according to their distributor list) so they are off the list.

I'm going to start with the 7,500km service intervals until I know the car well. I've always done an intermediate service on all my cars, simply for piece of mind. $60 or so for oil and filter every couple of months and an hour of my time I think is worth it. I hope to do 400,000km or more in this car. ( I got 333,000km out of the old VP Commodore it replaces and then only retired it due to an electrical gremlin)
