1. True or false, low tyre pressure has an impact on fuel economy?

True

False

Low tyre pressure can have a significant impact on fuel economy. When the tyre pressure is low, the rolling resistance of the tyres increases, causing the engine to work harder and consume more fuel to maintain the same speed. This extra effort required to move the vehicle results in decreased fuel efficiency. Therefore, it is essential to regularly check and maintain the recommended tyre pressure to improve fuel economy and reduce fuel consumption.

2. What is the most important thing to do before checking your engine oil?

Wipe the dipstick clean of oil

Shake off the oil on the dipstick

Tap the dipstick against the side of the engine

Fill up the oil

If you use the reading when you have first pulled the dipstick out it might not be accurate

3. Your car uses six primary fluids that should be checked on a regular basis. Which of these is not one of those six?

Engine oil

Coolant

Power steering fluid

Brake fluid

Tire fluid

Transmission fluid

Windscreen wiper fluid

The question asks which of the fluids is not one of the six primary fluids that should be checked on a regular basis. The six primary fluids that should be checked are engine oil, coolant, power steering fluid, brake fluid, transmission fluid, and windscreen wiper fluid. Tire fluid is not a primary fluid that needs to be checked regularly, therefore it is the correct answer.

4. If your car doesn't have a reservoir for antifreeze/coolant, you should wait until the engine has cooled down and pour the fluid directly into your...

Gas Tank

Radiator

Wind shield

None of the above

If your car doesn't have a reservoir for antifreeze/coolant, you should wait until the engine has cooled down and pour the fluid directly into your radiator. The radiator is responsible for cooling the engine by transferring heat from the coolant to the air. Without a reservoir, the radiator is the only place where the coolant can be added. Pouring the fluid into the gas tank or windshield would be incorrect as they are not related to the cooling system of the car. Therefore, the correct answer is radiator.

5. How long do car batteries last?

1-3 years

2-4 years

3-5 years

8-10 years

Car batteries typically last around 3-5 years. This is because over time, the chemical reactions within the battery that produce electricity become less efficient. Additionally, factors such as extreme temperatures, frequent short trips, and lack of maintenance can also contribute to a shorter lifespan for car batteries. Regular maintenance, such as checking the battery's voltage and keeping it clean, can help extend its life.

6. What is the most important thing to remember when tightening lug nuts?

To tighten the lug nuts in a clockwise direction

To tighten the lug nuts in an anticlockwise direction

To tighten the lug nuts in a criss cross pattern

When tightening lug nuts, it is important to remember to tighten them in a criss cross pattern. This means that you should start by tightening one lug nut, then move to the lug nut opposite to it, and continue in a diagonal pattern until all lug nuts are tightened. This ensures that the pressure is evenly distributed and prevents any one lug nut from being tightened more than the others. Tightening in a criss cross pattern helps to ensure that the wheel is properly secured and reduces the risk of it becoming loose while driving.

8. What is the biggest mistake people make when changing a flat tyre?

Jacking the car in the wrong spot on the frame

Not tightening the lug nuts enough

Not remembering to put the jack on level ground

When changing a flat tire, one of the biggest mistakes people make is forgetting to put the jack on level ground. This is important because if the ground is not level, it can cause the car to become unstable and potentially fall off the jack. It is crucial to ensure that the car is on a flat and stable surface before attempting to change a tire to ensure safety and prevent any accidents.
