What a car really costs to run
The purchase price is the part everyone plans for. Insurance, fuel, servicing, tyres, registration and the repair you did not see coming are the part that decides whether a car is affordable.

The true cost, line by line
Write down six numbers for a year: insurance, fuel, routine servicing, tyres, registration or plate renewal, and a repair fund. The repair fund is the one people leave out, and it is the one that causes the emergency.
Add depreciation if you plan to sell. A car that loses value quickly can cost more per year than a more expensive car that holds its price.
The service schedule that matters
Oil and filter at the interval in your manual. Tyre rotation roughly every second oil change. Brake inspection at least annually. Air filter, cabin filter, wiper blades and battery checked once a year. Coolant, transmission fluid and spark plugs at the longer intervals your manual sets.
Anything that is a safety item — brakes, tyres, steering, lights — is not a place to stretch an interval to save a month's cost.
Seasons change the list
Before winter: battery test, tyre condition or a switch to winter tyres, coolant strength, wiper blades, lights, and an emergency kit in the boot. Cold weather finds a weak battery the first hard morning.
Before summer: air conditioning, coolant level, tyre pressures as temperatures climb, and brake condition before any long trip with a loaded car.
The dates that cost money if missed
Insurance renewal, registration or plate renewal, any required safety or emissions inspection, your driver's licence expiry, and the end of any manufacturer or extended warranty.
Each of these has a fine, a lapse or a lost claim attached to it. Put them somewhere that tells you before the date — in HAUSINE these sit on the vehicle itself, with the documents beside them.
Keep the record with the car
Every invoice with the date and the odometer reading. Every tyre purchase. Every recall notice and what was done about it. Photographs of any damage and its repair.
When you sell, that folder is worth real money. When something fails, it is the fastest way for a mechanic to work out what has already been ruled out.
Common questions
How often should I change my oil?
Follow your owner's manual, not a sticker on the windscreen. Most modern engines using synthetic oil run somewhere between 8,000 and 16,000 kilometres, or roughly 5,000 to 10,000 miles, and many cars now calculate the interval for you. Short trips, towing and extreme cold shorten it.
What running costs do people forget?
Tyres, brakes, the annual registration or plate renewal, insurance increases at renewal, wiper blades and batteries, seasonal tyre changes and storage, parking, tolls, and the depreciation you only feel when you sell.
How long do tyres and brakes last?
Tyres usually give three to five years of normal driving, and are unsafe once tread reaches the wear bars regardless of age. Brake pads commonly last 40,000 to 80,000 kilometres, or about 25,000 to 50,000 miles, but city driving wears them far faster than highway driving.
How do I keep a useful service history?
Keep every invoice with the date and the odometer reading. A vehicle with a complete, dated service history sells for more and is far easier to diagnose when something goes wrong.
