It's a 2009 Ford Focus SES, a very nice vehicle. MSRP of $17,865 [1]. 7.1l/100km combined mileage [2]. Judging from the intervals so far(5000km, 10,000km), it looks like Ford wants me to change the oil every 5000km. The oil change cost me about 50 bucks.

So, I figure my annual cost of ownership this way: To own a car, I need to pay for it, I need to pay for insurance, I need gas, and I need to change the oil.

I assume that I want the 5yr, 100,000km powertrain warranty to last the whole 5 years I own the vehicle, limiting the distance travelled to 20,000km/yr. I assume gas is about a dollar per litre.

vehicle payments before taxes: $3573/yr insurance: $2100/yr Fuel: $1440/yr Oil: $200/yr

Total cost to own and operate the vehicle: $7313/yr

I bought a new car recently, and was running through the cost of ownership over the warranty period of the vehicle.

Compare to a 2009 Toyota Prius, another very nice vehicle. MSRP of $24,270 [3](This surprised me because it means the price went down considerably). 4.1/100km combined mileage [4]. The oil change interval appears to be every 8000km[5]. I'll assume the oil change will cost about the same.

Prices would need to double -- that is, they'd need to hit an average of $2.07/l ($7.8/usg) for a year for the vehicle to be a break-even deal.

I know my conclusions from this data, but feel free to form your own.
