We all know that cars need oil to run smoothly but knowing which oil your car needs and how often to check it can be confusing. That’s why, with the experts at Castrol, we’ve created this easy guide to answer your most common engine oil questions, from choosing the right oil for your vehicle to checking and maintaining oil levels for optimal performance.
What are the benefits of topping up your oil?
Keeping your engine oil topped up is important for many reasons:
- Better fuel efficiency: Good lubrication helps your engine run smoothly, reducing fuel consumption.
- Cleaner engine: Oil keeps dust and debris out of your engine, reducing the risk of clogging.
- Longer engine life: Topping up your oil helps your engine last longer, preventing unnecessary wear.
What to do if my oil warning light appears?
Your dashboard warning lights are your car’s way of communicating with you. If the oil warning light comes on, it’s an alert to check your oil level immediately. Ignoring it could lead to serious engine damage, so it’s best to check as soon as you can.
How often should I check my oil?
We recommend checking your oil every couple of weeks. Regular checks help ensure that your engine is well-lubricated and running smoothly, which can prevent costly issues further down the line.
How do I check my engine oil levels?
Checking your oil is a quick and straightforward process but if you’ve never done it before, here are a few simple steps:
- Park on level ground and turn off the engine, letting it cool for a few minutes.
- Locate the dipstick (it’s often marked with a brightly colored handle).
- Remove the dipstick, wipe it clean with a cloth, and then reinsert it fully.
- Pull it out again and check where the oil level falls between the markers. If it’s low, it’s time to top it up.
How do I top up my oil?
Remove the oil filler cap, then use a funnel to add the oil slowly. Check the level again using the dipstick and once the oil level is sufficient, ensure the oil cap is fully secured.
How do I know what engine oil my car uses?
The best way to find the correct oil for your car is to check your car’s manual or use Halfords’ online vehicle registration tool. Different cars require specific oil types, so it’s important to pick one that suits your vehicle’s needs. You can also drop by your local Halfords, where our experts can recommend the right oil for your car.
What do the letters and numbers mean on oil bottles?
The letters and numbers on oil bottles can be confusing. The first number indicates oil viscosity at low temperatures, while the second number shows viscosity at high temperatures. The “W” stands for ‘winter’. For example, 5W-30 is thinner in cold weather, making it more effective in lower temperatures.
What happens if I use the wrong oil?
Using the wrong oil type can result in serious engine damage, causing it to overheat and become clogged, so it’s essential to get this right!
Can I mix engine oils?
It’s not recommended that you mix engine oils from different brands, even if they are the same viscosity, as varying formulas can potentially impact your engine.
What can happen to my car if I don’t top up my oil?
Without sufficient oil levels, your car engine can’t stay lubricated, leading to excessive friction and wear. Over time, this can cause your engine to overheat and lead to costly repairs. In the worst cases, it can result in total engine failure.
Can topping up my engine oil regularly save me money?
Topping up your oil can help you avoid costly engine repairs. Additionally, with a well-lubricated engine, you’re likely to get better fuel efficiency, meaning you’ll save money on fuel too.
Does topping up my engine oil make my car last longer?
Yes, regular oil checks and changes can extend the life of your car. Regularly topping up oil reduces wear on engine components, helping your car run more smoothly and extending its life. Keeping your oil topped up is one of the easiest ways to make your car last longer and save on repairs.
