Task 3 Car servicing is something that every car owner has to experience at least sometime of the year. The best method to service your car is to go to your car service station and have the servicing done methodically according to your car maker. Consider this: Your car is up and running smoothly but the mileage figures indicate that you need to have it serviced. Certainly, this is the right thing to do but have you wondered what actually goes in to make you pay that servicing bill every 6 months? Servicing your car is a simply DIY job that you can learn quickly and easily save some good money. If you have never serviced your car before personally, here’s your resource: Servicing Basics. Car servicing essentially means inspecting the car thoroughly for any damaged components, and replacing some parts regularly that wear out over time. If you review carefully it is certainly possible to do all this by yourself, as bellow: You will need a complete set of tools as provided by your car maker when you purchased the vehicle. This will usually consist of all the spanners( 扳手 ) that you might need. Completely servicing your car will need a few hours but you will end up saving a lot of money. Besides, it’s fun too and a lot of learning. 11. What is the best way to service your car?A.
To service your car by yourself.
B.
To have your car serviced at the service station.
C.
To turn to other car owners for help.
D.
To send your car back to the car maker.
