The Prius major service occurs at 80,000km. That seems a bit early compared to 90-120,000km major service on my previous cars. One big difference is that I didn’t have to replace the water pump and timing belt. The Prius has a timing chain and there’s no set interval to replace it, just like old V8s.
Instead the parts to be replaced were fuel filter, including in-tank fuel filter, oil and filter and brake fluid. I’m slightly concerned that they used 10W-30 instead of 0W-20 oil considering how cold it has been and will continue to be. But at least the car got a proper service and now I’m starting to see fuel consumption in the threes.
Drove from home to Civic tonight on a warm engine. At the intersection of Northbourne and Antill Streets the HSI read 9.1km 2.8l/100km average speed 50km/h. That’s 100.9mpg(UK), 84.4mpg(US) and 35.7km/l. I reached Civic at 2.9l/100km and the round trip settled at 3.4l/100km. That is 1l/100km better than several comparable trips I’ve taken in a warmed car on a Friday night.
It’s no surprise that a major service should restore some vigour to the car. But since the change (on a sample size n=1) is so great… how was the car treated before I got it?!?
