Changing car oil regularly is essential for maintaining the health and performance of your car’s engine. In this blog, we will explore the importance of oil changes, how to check your oil levels, what the oil light on your dashboard means, the differences between synthetic and conventional oils, recommended oil change intervals, and the role of oil filters in the process. 

The importance of a regular oil change 

Keeping the engine clean: 

Regular oil changes help to remove contaminants and debris that accumulate over time. Clean oil ensures optimal engine performance and reduces the risk of engine damage. 

Low vehicle emissions: 

 Fresh oil helps to reduce harmful emissions from your vehicle, contributing to a cleaner environment. 

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. 

Optimum engine performance: 

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

How to check your 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

Why has my oil warning light come on? 

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 synthetic engine 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. 

How often should I change my 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. As a general guideline, it is recommended to change your oil every 5,000 to 7,500 miles or every six months, whichever comes first. However, always refer to your owner’s manual for the manufacturer’s specific recommendations. 

What engine oil do I need? 

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

Oil change intervals for older cars 

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. 

Oil Change Intervals for New Cars 

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.

When to Change Your Oil Filter?

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.
