# Are diesel prices going down?

The site also estimates the change in the cost of a full 60-litre tank by multiplying the statewide change in cents per litre by 60 and converting cents to Australian dollars. This is an illustration based on an assumed tank size, not a quoted station price.

This site answers whether the latest NSW-wide average regular diesel price is lower than yesterday's final average. It uses current NSW Fair Trading FuelCheck prices for fuel code `DL`. "Yes" means lower; "No" means higher or unchanged. Until both daily averages are available, the answer is unknown.

The [live JSON summary](https://diesel-direction.askinner.workers.dev/api/summary) gives the answer, averages in cents per litre, and the latest price check time. To find nearby stations, pass both `lat` and `lon` in decimal degrees. The response returns up to five distinct stations within a 10 km straight-line radius, ordered by price then distance. No station list is returned without coordinates, and the service does not infer location from an IP address.
