My dad bought another Hiace home 2 days ago, with the license plate starting with "GY". I told him we shld exchange our license plates, as my name is then "GY". Anyway, this van is really v big and nice as compared to the Liteace. Sometimes i wonder whether we doing a van rental business or delivery business, instead of the miserable karaoke rental business.
Recently, i noticed that my fuel consumption has dropped from a healthy 15km/lit to 13km/lit, esp after i sent my van for servicing. I decided to heed the advice from some eurovan-seniors and inflated my wheels to 250psi. And it turns out to be very true that i really save a lot on my fuel! My ex-foreman and I must have thought the tyre standards for van is the same as the normal saloon cars - which is 220psi.
I duno if my theory and analysis is right, but this is how i guess it works:
- A 250psi inflated tyre has a circumference of 150cm (not real figure)
- A 220psi inflated tyre has a circumference of 145cm
=> 5cm difference per revolution
- Distance travelled everyday is 50km
=> 1,000,000 revolutions saved everyday
If the above analysis is true, then i can see why the mileage i clocked over the past week is significantly much lesser than what I had over the past 2 months! Anyway, the most impt thing is i am saving $$$!
