Motor oil serves as the essential lifeblood of any vehicle's engine, playing a crucial role in maintaining optimal performance and longevity.
Periodic oil changes are a fundamental aspect of car maintenance that every vehicle owner should prioritise.
Understanding when and how to change motor oil, as well as how to dispose of it properly, is vital for keeping an engine running smoothly and efficiently.
Engine Oil Change: Interval and Price
The regularity of oil changes depends on various factors, including the vehicle's age, mileage, and manufacturer recommendations. Generally, it's advised to change the oil at least once a year, or between 10,000 and 20,000 kilometres, whichever comes first.
However, if a vehicle has already reached these mileage milestones, it's best to change the oil, even if a year hasn't passed since the last change.
Diesel engines may demand more periodic oil changes compared to gasoline engines. Additionally, some diesel vehicles may need periodic refilling of diesel exhaust fluid (urea) to reduce nitrous oxide emissions.
The cost of an engine oil change can differ depending on some factors. They include the type of oil used, the size of the engine, and the location where the service is performed. For an independent mechanic, the cost typically ranges from 30 to 60 euros.
If synthetic oil is chosen, the price can increase to around 90 euros. Authorised workshops may charge double these amounts due to higher oil costs per litre and labour rates. When considering the price of an oil change, it's important to factor in the cost of the oil filter as well.
A quality oil filter generally costs around 10 euros. While it may be tempting to opt for a cheaper filter, investing in a high-quality one can provide better protection for the engine and potentially last longer.
For a complete oil and filter change service, vehicle owners can expect to pay between 70 and 80 euros for a small car. This price may increase for larger vehicles or those requiring specialised oils.
When to Change the Oil
Several indicators suggest it's time for an oil change. These include the illumination of the engine oil warning light on the dashboard and unusual engine noises. Regular checks of the oil level, at least once a month, can help identify when an oil change is necessary.
One clear sign that an oil change is overdue is when the oil becomes thick, black, and viscous. In this state, the oil is no longer able to properly lubricate all engine parts, potentially leading to damage from friction or overheating.
Step-by-Step Guide to Changing Motor Oil
- Warm up the engine to ensure proper oil drainage
- Find the oil drain plug. Then, put a container underneath
- Extract the oil filler cap and drain plug to allow oil to flow out
- Replace the drain plug and tighten it securely
- Add new oil through the filler hole, using the correct type and amount
- Restore the oil filler cap and inspect for leaks
- Run the engine momentarily to distribute the new oil
- Inspect the oil level with the dipstick and top up if necessary
Proper Disposal of Used Motor Oil
Wrongful disposal of used car oil can have severe environmental consequences. It's crucial to dispose of used oil responsibly.
Many local auto parts stores, service stations, and recycling centres accept used motor oil for proper disposal or recycling. Never pour used oil down drains, into the ground, or mix it with other substances.
Used motor oil can be recycled and refined into new oil products, helping to conserve resources and protect the environment. Some areas may have specific regulations regarding the disposal of used motor oil, so it's important to check local guidelines.
Benefits of Regular Oil Changes
Maintaining a regular oil change schedule offers numerous advantages. It helps improve engine performance, extends engine life, and can even enhance fuel economy. Clean oil effectively lubricates engine components, reducing friction and wear.
Some motor oils contain additives that can further protect the engine from wear and stress, potentially increasing its long-term performance. These additives can help reduce engine deposits, improve fuel efficiency, and provide better protection in extreme temperatures.
Keeping the Engine Running Smoothly
Routine oil changes are an intrinsic part of vehicle maintenance. By understanding when and how to change motor oil, as well as how to dispose of it properly, vehicle owners can ensure their engines run smoothly and efficiently for years to come.
Prioritising this simple yet essential maintenance task can lead to improved performance, longevity, and potentially significant cost savings in the long run.
Maintaining a consistent oil change schedule, using high-quality oils and filters, and following proper disposal procedures not only benefits the individual vehicle but also contributes to environmental conservation efforts.
