In the mean time, if you want to test your knowledge of car maintenance, why not try our quiz? It’s fun and it’ll help give some tips and pointers for what you should do to keep your car in top shape – other than taking it for a free vehicle health check.


Well done. You certainly seem to know your car and how to look after it.
Hmmm. These are all basic jobs and you should be carrying them out on a regular basis. We have plenty of helpful tips and expert advice on Green Flag Blog.

#1. What is the minimum legal tread depth for a car tyre?

You need to check up on your Highway Code. The minimum legal tread depth is 1.6mm although some car makers suggest changing tyres at 3mm.

#2. Your headlight has a cracked lens. You should…

A cracked headlight lens is an MOT failure point and it might even result in water getting into the delicate electrics of your car. You should replace it.

#3. How often should you change your car's windscreen wipers?

Windscreen wipers have a life span like many other moving parts of the car. It’s safest to change them before they wear out which means swapping them roughly every two years.

#4. Which of these statements about engine oil is false?

Engine oil is the lifeblood of an engine and it’s vital to check it on a regular basis as low oil can shorten an engine’s lifespan.

#5. How often should you check your tyres?

Experts from tyre companies recommend you check your tyres’ pressure and tread depth once a fortnight.

#6. Where will you find the reservoir for the brake system?

The reservoir for the brakes is found in the engine bay. It shouldn’t need topping up but it’s advisable to check the level of fluid in it just in case.

#7. When topping up your car’s coolant, which most accurately describes what you should use?

If it’s an emergency you can use water but you should really test the concentration of the anti-freeze in the system before filling it accordingly. Anti-freeze that is too diluted won’t work properly in cold weather.

#8. If the red oil warning light pops up on your instrument panel while you're driving you should…

You should stop immediately. That light only appears if your engine doesn’t have sufficient oil or the oil isn’t getting to where it should in the engine. Continuing to drive can cause significant, possibly permanent damage.

#9. Do you need to check how much fluid is in your engine’s coolant system?

It’s true that engine coolant systems are sealed but coolant can still leak out so it’s worth checking.

#10. What do you do when your engine needs oil?

Having too much oil is almost as dangerous for an engine as having too little. So pour in a little at a time, measuring it on the dipstick to know when it’s full enough. And remember it can take a little bit of time for the oil to make its way down the filler pipe into where the dipstick measures it.
