    My 2008 Ford Falcon has 250,000km on the clock. What grade oil should I use?

    Most oil manufacturers familiar with this make and model recommend either a full or semi-synthetic oil with a viscosity of 5W30 or 10W30. So that's what we'd recommend, too. You could probably go to a 20W40 without doing any damage, but why change if there's no need to?

    Unless the engine is really worn out and starting to burn oil, there's not much point going to a thicker (heavier) oil. And the reality with this engine (and many like it) is that 250,000km is not actually super-high mileage these days. Back in the 1950s and 60s when an engine was often worn out at the 100,000km mark, things were different, but modern metallurgy and production tolerances (not to mention taller gearing) mean that an engine with 250,000km on board can still feel and perform like a new one. So treat it like one.
