The simple things can help keep a car in good nick between services. Keep your precious motor fine-tuned with these basic fluid level checks.

1. Dipstick dos and don'ts
Find the dipstick (see the handbook). Take it out, wipe it with a rag and replace it, then remove it again and check. Top up the oil as necessary, adding a little at a time.

2. Colour alert
If the oil on the dipstick is black and grimy or light brown and emulsified, your engine needs urgent attention. Go to a mechanic as soon as possible.

3. Water marks
If the plastic tank linked to the radiator needs topping up, make sure the engine is cool and then add the right mixture of antifreeze and distilled water (see your handbook).

4. Brake fluid
This is especially important as a leak in the braking system can kill you. When removing the cap from the fluid reservoir (see your car manual), wipe off any dust. Seek help if the fluid level goes up and down or is empty.

5. Other fluids
There are fluid reservoirs for power steering, automatic gearboxes and clutches. If you need to top them up, consult the handbook for the correct fluid to add.
