2016-03-10: 773km, 86L, 11.12L/100km, 14c/km so far. I am a heavy city driver.
2016-03-23: a 187km joyride up to Putty Road consumed 10.7L/100km on average, equating to exactly 20L for the trip. Assuming average of last fill and current fill, that's $25.50, ouch.
2016-03-29: Home, work, city, Kat's place, home; can be done for about 7.5L/100km if I'm reasonable, about 95km or so.
2016-04-25: Filled up with 46,196 on the odometer, having travelled 2959 km since purchase while consuming 298.82 litres of fuel. Average mileage of 10.1L per 100km.
- That's $492.65 spent on fuel, or 16.65 cents per km.
- Average 44km to go visit Kat and return home == 4.4L == $7.32
  - That's actually cheaper than public transport, just considering fuel costs ($4.50 each way)
  - Fuel consumption is lower when I do a whole-day round trip including work at ATP. If it were fair scaling, that'd be 3.67L == $6.11
2016-08-07: 6764km, 670L, 9.91L/100km, 12.36c/km so far. My drives tends to be a bit heavy.
- That's 163 days, or 23.25 weeks. Averaging $36/week on petrol, driving 291km/week while consuming 28.82L.
2019-09-14: We drive a lot less now, which is great. In the last 4 months or so (18.2857 weeks) we've driven 2278km, consumed 196.63L of petrol, and spent $290.51 on it.
- That's about 12.75c per km travelled, and mileage of 8.63L per 100km. Nice!
- We're driving about 125km per week, or 540km per month. That's gonna put us way down statistically; unless we do some big road trips that's under 7000km per year.
2022-06-19: In the last 17-and-a-bit weeks we've driven 4589km, which equates to 270km per week.
- Assuming 4.33 weeks per month, that's 1150km per calendar month.
- In that time we've consumed 390 litres, meaning our economy is almost exactly 8.5L per 100km.
- 1150km per month means we're consuming 98 litres per month. This is up from last time I worked the budget, which assumed 80L/mon.
- To be safe, budget for 105L/mon. Prices are peaking around $2.25~2.30 per litre. That's $236/mon.

Driving further for cheaper fuel

Riverstone Petroleum is much cheaper than the big brand servo chains and you get ULP 98 instead of 95 while you're at it. Assuming you don't care about the latter, is it worth it travelling the extra distance for cheaper fuel?

A round-trip from home to Riverstone is about 14km, and it's not on the way to/from anywhere, which means we'll consume 1.12L of petrol just to do it. In monetary terms that's about $2.60, so you'd better be making that up in savings.

If Riverstone is 10c/L cheaper, which is a fair guess, then it's worth making the trip as long as you're filling up 25L or more. To generalise this to an equation:

X = number of litres to break even
x = price of fuel at expensive servo, in cents (eg. 233)

X = 1.12 * ((x/10) - 1)

Perhaps of more interest, how big a difference is worthwhile for a normal fillup? We tend to fill when the tank is down to quarter full, meaning a 45L-or-more fill. Let's use 45L as the benchmark.

x = expensive price = 233c for this exercise
y = price gap at cheaper place, in cents

Find breakeven with these simultaneous equations:

45L at 233 cents = $104.85 (real)
46.12L at (233-y) cents = $104.85 (hypothetical)

Breakeven would be at 227.3c/L, meaning y = 5.66c difference. Rework the equations:

1.12x = 46.12y
x = 41.179y
x/41.179 = y

So Riverstone had better be at least "Big Chain Price divided by 41.179" cents cheaper. Because we're happy enough to err on the side of doing less driving, just round down and make it a factor of 40.

Take the Big Chain Servo price in cents, divide it by 40. If Riverstone is at least that many cents cheaper, it's worth it.

If petrol were $5.00 per litre, then Riverstone needs to be 12.5c cheaper to be worthwhile. If petrol were $1.20 per litre, a difference of 3c would be worthwhile.

Took ownership around 2015-08-08, which is 16 weeks ago (now 2015-11-28).

Total cost is $652.21 which amounts to $40.76 per week. I've driven *roughly* 4000km, which makes it **about 17c per km**.

Total consumption of 441.8 litres, making it about 11L per 100km, or a little less possible. That's pretty much as expected for urban driving, but I've definitely done plenty of open road driving as well, which should have dropped it somewhat.

Car was sadly written off as a result of the engine being flooded during torrential rain, around January 2016.
