 A:Welcome to Al’s Garage. What seems to be the  problem?                                                                               
 B:No problem at all! I am taking a long road trip and I want to make sure my car is in good mechanical  condition.                     
 A:Very wise decision. When was the last time you  had a tune up?                                                                       
 B:Not that long ago, I think it was four months ago.                                                                                   
 A:We usually recommend that you bring your car in  every five thousand kilometers.                                                     
 B:Why? I mean, what exactly do you do to a car that  you need to check it so often?                                                    
                                                                                                                                        
 A:First of all, we change the motor oil and oil filter. If  you don’t do this, it can cause your engine to wear  faster and that       
 means you would probably have to  change the pistons and intake valves.                                                                
 B:I see. What else?                                                                                                                    
                                                                                                                                        
 A:We also check your spark plugs, fuel filter, and  other oil levels such as hydraulic fluid. We also  check the clutch and brakes to  
 determine when   you will need new ones.                                                                                               
 B:Ok, well, when you put it that way, it doesn’t seem  like a waste of time and money.                                                 
 A:Trust me, regular tune ups will keep your car running smoothly and avoid break downs.
