Could those of you with penchant for sums agree with this figure?

Seems hight to me.

A quarter of that would be more like it.

667500 2008-05-09 03:34:00 When you factor in purchase cost, depreciation, repairs and maintenance, insurance, fuel, registration and WOF - 90 cents per km would be pretty close.

IRD allows something like 70 cents per km for mileage claims (up to 2L cars, I think)

667502 2008-05-09 04:48:00 Nah, thats impossible unless it's turbo and always running on high boost, or a really really weak 2 litre engine on a really heavy car, driven by a guy with a 200kg right foot. Or maybe they get their figures from drag racers? Who use super expensive fuel in their super powered cars?

Driving as hard as I can (within legal bounds), the worst mileage I've obtained has been 7.3 Km per litre (91 unleaded). Assume 1 litre is $2 (it's close enough now :S), so $2 gets you 7.3km. $1 -> 3.65 Km. $0.90 -> ~3.3 Km.

I'd say fair average (according to my results - with *normal* driving, includes mixture of afternoon 'Auckland motorway boogie' + a few 'short' drives and some longer ones of ~20 k's each) should be more like $0.90 should be getting ~4.3 Km (20~30 cents per kilometre).

These measurements relate to my MR2 in stock form. Note, that is a 1991 'sports' vehicle with manual transmission. It's almost 20 years old now and I'm sure that if you picked up a 2 litre car of today, as long as it's not turbo you could probably expect heaps better mileage.

Driving as hard as I can (within legal bounds), the worst mileage I've obtained has been 7 . 3 Km per litre (91 unleaded) . Assume 1 litre is $2 (it's close enough now :S), so $2 gets you 7 . 3km . $1 -> 3 . 65 Km . $0 . 90 -> ~3 . 3 Km .

Now like johcar, factor in your yearly insurance, wof, rego, oil, tyres and servicing . . . . The calculation that AA does includes everything . . . . not just gas

So if you were lending a friend a car for a week every month for business,you would fairly expect them to pay what per k?

Throw in parking too. If you're paying for car parking in a city, well, it's a lot of money ....

Oh ok, sorry. I had no idea the AA figures were for overall costs as there was no mention of it in the thread.

By the way, I don't see the relevancy in trying to compare things that way, isn't that a bad idea? We are not even talking about *specific* car models here so there is no fair comparison.

For starters, considering we are talking of cars, and not trucks, why should wof/rego be included? Warrants are a constant. In case you didn't know, registration is also a constant (it is same cost for cars all the way up to 2600cc, it is only different in petrol vs. diesel where I believe diesel cars cost more to register).

Parking doesn't cost any more if the engine is 800 or 8000cc.

Insurance is completely dependent on the exact vehicle (type/modifications) and it's owner (age/history).

As for oils, anyone with good preventative maintenance principles (most of us service our cars atleast once a year don't we?) will get the oils replaced long before it actually NEEDS to be. In a healthy car, you might top up maybe 100 ml's of semi-syntehtic every 5,000 k's (personally I'd just flush/re-fill @ ~10,000 or half yearly, whichever comes first - no matter what car I drive). That is $1.20 per 5,000 k's @ $12 a litre for engine oils (thats $0.00024 km in engine oils). I don't know about auto-transmission fluid as I've never had to buy any of that. Might have to have my gearbox oil refilled though, which will set me back $120 including labour per 60,000 km.

Can't find logic in tyre costs being any different in a car with a specific engine size vs. another at all. Provided you compare vehicles with same engine/drive config, same conditions, same tyres, and same driver. They should wear evenly, so another constant.

This is all provided it is not some kind of Ferrari you are talking about, in which case you might want to factor in huge maintenance costs including new $4000 tyres every 20~30,000 k's etc.

Most sensible answer I can think of: The cost of owning a 2 litre car is completely independent of vehicle/driver/owner/conditions. Only things that will should cost more with a 2L engine vs. a 1.6 is petrol and potentially engine oil (in New Zealand).
