Oil Change: Signs and How to Change Your Cars Oil

Regular oil changes are crucial for maintaining the health and performance of your car’s engine. By regularly replacing the oil, you can ensure that your engine stays properly lubricated and protected from wear and tear. In this article, we will explore the signs that signify your car needs an oil change and provide a step-by-step guide on how to change your car’s oil.

So you may be wondering why and how engine oil becomes dirty here’s why: when oil is first put into your engine, it appears golden-brown as it moves through the engine. When an engine runs, the metal parts inside it rub against each other, generating small metal particles known as wear metals. These wear metals can combine with oil to form sediments, which are thick, dark substances that can clog oil passages and reduce the oil’s ability to lubricate and protect the engine.

Types of Motor Oil

it’s important to familiarize yourself with the different types of motor oil available:

1. Conventional oil

Conventional oil is the most basic type of motor oil, suitable for regular driving conditions. It provides adequate lubrication but may require more frequent oil changes compared to synthetic options.

2. Synthetic oil

Synthetic oil is chemically engineered to offer superior lubrication and performance in extreme temperatures and high-stress driving conditions. It generally lasts longer and provides better engine protection.

3. High mileage oil

High mileage oil is specifically formulated for vehicles with higher mileage, typically over 75,000 miles. It contains additional additives to minimize wear and tear on ageing engine components.

Recommended oil change intervals varys depending on the make and model of your car. It’s important to consult your owner’s manual or the manufacturer’s recommendations to determine the appropriate interval for your vehicle.

Signs That Your Car Needs an Oil Change

1. Dashboard Warning Lights

Modern vehicles are equipped with sophisticated dashboard warning lights that monitor various aspects of your vehicle’s performance. If the oil pressure or oil level warning light shimmers, it’s a clear sign that you should check your oil level and schedule an oil change if needed.

2. Strange Engine Noises

When your engine lacks sufficient oil, you may start noticing unusual noises, such as knocking, ticking, or grinding sounds. These noises often indicate that the engine parts are not properly lubricated, highlighting the need for an oil change.

3. Decreased Fuel Efficiency

If you’ve noticed a sudden drop in your car’s fuel efficiency, it could be attributed to dirty or old oil. When the oil becomes polluted, it loses its ability to reduce friction and keep the engine running smoothly, resulting in increased fuel consumption.

4. Dark, Dirty Oil

Checking your car’s oil colour and consistency regularly can give you important clues about its condition. Clean oil is amber or light brown, while dark, dirty oil indicates that it’s time for a change. Dirty oil can contain contaminants that can harm your engine’s performance.

5. Oil Smell Inside the Car

In some cases, you may detect a strong oil smell inside your car’s cabin. This odour often indicates an oil leak or spillage, which should be addressed immediately to prevent any damage to the engine.

How to Change the Oil in Your Car

To perform an oil change, you will need the following tools and materials:

•  A socket wrench or wrench set
• An oil filter wrench
• An oil drain pan
• A new oil filter
• The recommended type and amount of oil for your car
• A funnel
• Safety gloves and goggles

1. Park the Car on a Flat Surface and Jack It Up

Before getting started, ensure that your car is parked on a level surface, then raise the car high enough to allow you to work underneath it. Make sure that you are completely safe whether you use a hoist, ramp, or jack stand. Never work underneath a car that is only supported by a floor jack. Gather all the necessary tools and materials to have them within easy reach during the oil change process.

2. Draining the Old Oil

• Locate the oil drain plug: The oil drain plug is typically located underneath the engine, towards the bottom. Consult your owner’s manual if you’re unsure about its exact location.
• Position the oil drain pan: Place the oil drain pan directly beneath the drain plug to catch the old oil.
• Remove the drain plug and let the oil drain: Using a socket wrench or a wrench set, carefully loosen and remove the drain plug. Allow the old oil to flow freely into the drain pan until it stops.

3. Removing and Replacing the Oil Filter

• Locate the oil filter: The oil filter is usually located near the engine block. Check your owner’s manual to locate its specific position.
• Use an oil filter wrench to remove the old filter: Attach the oil filter wrench securely around the old filter and twist it counterclockwise to loosen and remove it.
• Apply a thin layer of oil to the rubber gasket of the new filter: Before installing the new oil filter, apply a small amount of fresh oil to the rubber gasket to ensure a proper seal.
• Screw the new filter into place: Carefully plait the new oil filter into position by turning it clockwise. Use your hands to tighten it securely, but avoid over-tightening.

4. Add The New Oil

• Check the recommended oil type and capacity: Refer to your owner’s manual or consult the manufacturer’s guidelines to determine the suitable oil type and the amount of oil needed for your car.
• Use a funnel to pour the new oil into the engine: Insert a funnel into the oil filler hole and slowly pour the new oil into the engine. Take care not to overfill, as it can lead to performance issues.

5. Check the Oil Level

• Let the oil settle for a few minutes: Allow the newly added oil to settle for a few minutes before checking the oil level.
• Remove the dipstick and wipe it clean: Locate the oil dipstick, pull it out, and wipe it clean with a lint-free cloth or paper towel.
• Reinsert the dipstick and check the oil level: Fully reinsert the dipstick into its tube, then pull it out again. Check the oil level against the markers or indicators on the dipstick. If it falls below the recommended level, add more oil as needed.

6. Dispose of the Old Oil

Used oil is considered a dangerous waste and should never be disposed of in regular trash or poured down drains. Take the old oil and the oil filter to a recycling centre or an authorized oil change facility for proper disposal.

Tips for Maintaining Your Car’s Oil

1. Regular Oil Checks Between Changes

In addition to scheduled oil changes, occasionally check your oil level and condition to ensure it remains within the advised range. This approach allows you to detect any potential issues early on.

2. Checking for Oil Leaks

Inspect your car’s engine bay and the area beneath the car for any signs of oil leaks. Address any leaks promptly to prevent further damage to the engine and ensure optimal oil levels.

3. Monitoring Oil Quality

Keep an eye on the oil colour and texture during your regular oil checks. If the oil appears excessively dark or dirty, it may signify a need for an early oil change or an underlying engine problem.

4. Following the Manufacturer’s Guidance

Always follow the oil change intervals and suggestions provided by your car’s manufacturer. They are tailored to your specific vehicle and driving conditions, ensuring optimal engine performance and longevity.
