Frequently Asked Questions
Q1: What is the most important part of car maintenance?
A1: Regular oil changes and checking tyre pressure are among the most critical maintenance tasks to ensure your car runs smoothly and safely.
Q2: What does it mean if my car's 'check engine' light is on?
A2: The 'check engine' light (or 'engine management light') indicates a potential issue with the engine or its emissions system. It's best to have it diagnosed by a mechanic.
Q3: How often should I get an MOT test?
A3: In the UK, most cars over three years old require an MOT test annually to ensure they meet roadworthiness standards.
Q4: What's the difference between a petrol and a diesel engine?
A4: Petrol engines use spark plugs to ignite a fuel-air mixture, while diesel engines use compression to ignite the fuel. Diesel engines are generally more fuel-efficient but can be more expensive to maintain.
Q5: What should I do if I have a flat tyre?
A5: If you have a spare tyre and the necessary tools, you can change it yourself. Otherwise, it's advisable to call for roadside assistance.
