Here in Australia the standard service interval for that car (as recommended by Toyota), is 15000km (9300 miles) or 12 months.


Correct, but severe service is half that, so 4660 miles / 6 months (which i follow due to short trips, albeit not in the cold).

Interesting... Thanks.

Interesting, it would seem like MPG would be pretty relative to the car.

Yes. The average MPG you're expecting to achieve over the course of the OCI helps account for things like city/hwy driving, or driving short distances in cold climates - all of these affect MPG, and the more fuel you burn over the same distance, the more severe the service. The OLM in my 530i is based on amount of fuel burned alone.

Here's more info on TooSlick's formula:

Hmm interesting... my Accord came out 5341 miles... (.8)*(9.1)*(9.1)*(26mpg)*(4.5qt)*(184ci/267hp). On Pennzoil Ultra?

Yeah, his formula penalizes small sumps with high HP as you can see.
