When it comes down to improving the performance, longevity and health of your car engine, you certainly shouldn’t look past regular oil changes. Oil change intervals are set by manufacturers, giving you a rough guide on when you should look to change the oil in your engine. Usually, manufacturers recommend that you replace your car’s engine oil after you reach a specified amount of miles or how long you’ve had the vehicle. In this blog, we’ll take a look at the importance of regular oil changes, how you can check your oil levels, the role of oil filters, and the recommended oil change intervals for some of the top car manufacturers!

Why is it Important to Change Engine Oil?

Before we go into more detail about oil change intervals, you might be wondering why you need to change your engine oil in the first place. Here are just three reasons why you need to change your engine oil!

Keeping the engine clean

One of the main benefits of changing your car oil is that it helps you maintain a clean engine. Over time, oil can collect contaminants and debris from the engine’s internal combustion process. Dirty oil in your engine can damage its components, resulting in a decline in engine performance. Changing your oil regularly means that you can flush out these contaminants and prevent them from circulating around the engine.

Low vehicle emissions

Changing your car’s engine oil can also help protect the environment. Clean, fresh oil means that a vehicle can run more efficiently, with better combustion, less engine wear, and a functional emission control system.

Improved mileage

By reducing friction and maintaining proper lubrication, regular oil changes can improve fuel efficiency and help you get the most out of every litre of fuel. 

Better engine performance

Clean and properly lubricated engine components result in smoother operation, reduced wear and tear, and improved overall performance. 

How to Check Engine Oil Levels

To ensure your engine has adequate oil levels, follow these steps: 

  1. Park your car on a level surface and allow the engine to cool down. 
  2. Locate the oil dipstick, usually indicated by a brightly coloured handle. 
  3. Pull out the dipstick, wipe it clean with a cloth, and reinsert it fully. 
  4. Remove the dipstick again and check the oil level against the markings on the dipstick. 
  5. If the oil level is below the recommended range, it’s time to add more oil. Consult your owner’s manual for the correct type and quantity of oil for your car

What Does the Oil Warning Light Mean? 

When the oil light on your dashboard illuminates, it can indicate low oil pressure. This drop in oil pressure could be due to several factors, including: 

Low oil level: Your vehicle may be running low on oil, requiring a refill. 

Dirty oil: Oil that is contaminated or hasn’t been changed for a long time can trigger the oil light. 

Oil leak: A leak in the engine oil system can lead to decreased oil pressure and trigger the warning light. 

If your oil light comes on, it is crucial to address the issue promptly to prevent potential engine damage. Check the oil level and consult a mechanic if necessary. 

What is the Difference Between Semi Synthetic and Fully Synthetic Oil? 

Synthetic oil is a lubricant made from artificially created chemical compounds. It offers several advantages over conventional oil, including: 

  1. Better temperature resistance and stability, ensuring consistent lubrication in extreme conditions. 
  2. Enhanced engine protection and reduced wear and tear. 
  3. Improved fuel efficiency. 
  4. Extended oil change intervals. 

Semi-synthetic engine oil, as the name suggests, is a blend of synthetic and conventional oils, offering a balance between performance and affordability. 

Can You Mix Synthetic and Semi-Synthetic Oil?

It’s recommended that you do not mix synthetic and semi-synthetic oil because this can change the properties, leading to issues such as poor lubrication and decreased engine performance. Instead, it’s best to follow the recommendations set out in your manufacturer’s vehicle guidelines. For further advice, you can always consult your local mechanic.

How Often Should I Change My Engine Oil? 

The frequency of car oil changes depends on various factors such as the age of the car, the type of oil used, and driving conditions. Take a look at the list below to see the recommended oil change intervals for some of the most popular car manufacturers!

BMW Recommended Oil Change Intervals

BMW recommends that you have a “Safety & Oil Service” every 15,000 miles or after 12 months, whichever comes first. This service includes changing the oil filter and inspecting the vehicle. 

Ford Recommended Oil Change Interval

The oil change intervals for Ford vary by vehicle and engine type, however you can use their maintenance schedule portal to find out the intervals for your specific vehicle.

KIA Recommended Oil Change Interval

KIA states that ‘5,000 to 7,000 miles is a good guideline for oil change frequency’. They do note that different driving styles can influence how often you have your car’s oil changed. For instance, off-road driving and heavy towing can cause more stress on your engine than regular driving, therefore it would need an oil change on a more regular basis.

VW Recommended Oil Change Interval

Volkswagen state that an oil change should occur every 10,000 miles or 12 months, whichever comes first. It’s important to note that is just a rough guideline, and you should consult your vehicle manufacturer guide to see which is the suitable intervals for your vehicle!

Audi Recommended Oil Change Interval

Audi’s website state that an oil change can be required anywhere between 9,300 miles and 18,600 miles. In order to receive specific information about the oil change intervals for your Audi vehicle, it’s recommended that you consult your vehicle’s handbook.

What engine oil do I need? 

To find the correct engine oil for your car, you can refer to the owner’s manual or even ask a member of staff at APD Car Parts. Remember to always follow the manufacturer’s recommendations. 

How Often Should You Change Oil in an Old Car?

Older cars may require more frequent oil changes due to their age and potential wear and tear. Consult your mechanic or refer to the owner’s manual for specific recommendations. 

How Often Do New Cars Need Oil Changes?

Newer cars often come equipped with advanced technology that automatically detects when an oil change is needed. These systems take into account factors such as mileage, driving conditions, and engine performance to provide more accurate oil change intervals. Check your vehicle’s manual or consult a dealership for information on your specific model. 

Different Grades and Quality of Car Oil 

Engine oils come in various viscosity grades, indicated by numbers such as 5W-30 or 10W-40. The lower the number before the “W,” the better the oil performs in cold temperatures. Higher viscosity oils are better suited for maintaining film strength in high-temperature conditions. Choosing the right grade depends on your vehicle’s specifications and the climate you drive in. 

For high-quality engine oil, consider the benefits of Liqui Moly’s products: 

Enhanced lubrication: It provides superior lubrication, reducing friction and wear on engine components. 

Engine cleanliness: Liqui Moly oils have detergent properties that help keep the engine clean by minimising deposits and sludge buildup. 

Improved performance: The oil’s advanced formulation can enhance engine performance and fuel efficiency. 

Extended engine life: With its high-quality additives and protective properties, Liqui Moly oil can contribute to the longevity of the engine, reducing the risk of premature wear.

How Often Should Oil Filter Be Changed?

When changing car oil, it is recommended to replace the oil filter as well. The oil filter plays a crucial role in removing contaminants from the oil, ensuring cleaner oil circulates through the engine. For guidance on oil filter replacement, refer to your owner’s manual or consult a trusted source like APD’s website

The oil filter in a car removes contaminants from the engine oil to prevent damage. It captures dirt, metal particles, and sludge, keeping the oil clean. Over time, the filter may get clogged, so regular replacement is necessary. It ensures engine longevity and performance. 

Understanding oil change intervals and the importance of regular maintenance is vital for preserving the health and performance of your car’s engine. By following recommended guidelines, checking oil levels regularly, and using the right oil and filters, you can ensure your engine operates smoothly and efficiently for years to come. Remember to consult your owner’s manual and seek professional advice when needed.
