What is the best type of oil to use in a 2009 Ford Falcon XR6T?

Asked by Phil

What is the best type of oil to use in a 2009 Ford Falcon XR6T with 170,000kms? I'm in Tasmania so it obviously gets cold here with very low single-figure degrees in winter. But, no doubt surprisingly to mainlanders, it also gets well into the 30s in the summer as well.

A good multi-grade oil is what you’re after; one that is thin enough to circulate and protect quickly in cold conditions, but also able to cope with the heat and stress inferred by a turbocharged engine in hot conditions. Options include a 5W30 oil or even a 10W40, but make sure that the API rating is suitable for your car. The correct API rating ensures that the oil is of a sophistication in keeping with the technology in your engine.

The other critical piece of advice is to use a quality oil from a reputable brand. Ignore the supermarket-shelf stuff and, if you’re having the car serviced at a workshop, don’t forget to ask what brand and grade of oil it intends to use. A fully synthetic oil will cost more but will offer more protection for an engine such as the hard-working turbomotor in an XR6T.
