Change Engine Oil In Car

Change Engine Oil in car is a fundamental maintenance task that can help prolong the life of your vehicle’s engine and ensure optimal performance. While it may seem daunting at first, with the right tools and knowledge, you can easily perform this task yourself and save money on professional services. In this guide, we’ll walk you through the step-by-step process of changing engine oil in your car.

Introduction

Regularly changing the Engine Oil in your car is essential for maintaining its health and longevity. Engine oil serves several crucial functions, including lubricating moving parts, cooling the engine, and cleaning contaminants. Over time, oil breaks down and becomes less effective, potentially leading to engine damage if not replaced regularly. The frequency of oil changes varies depending on factors such as driving habits, vehicle age, and manufacturer recommendations.

Gathering Supplies

Before you begin, gather the necessary supplies, including:

  • New engine oil
  • Oil filter
  • Socket wrench or box-end wrench
  • Oil filter wrench
  • Drain pan
  • Funnel
  • Safety gloves and goggles

Preparation

Start by parking your car on a level surface and allowing the engine to cool down. It’s crucial to work on a cool engine to avoid burns. Additionally, wear safety gloves and goggles to protect yourself from hot oil and debris.

Locating the Oil Drain Plug and Oil Filter

Refer to your car’s owner’s manual to locate the oil drain plug and oil filter. Typically, the oil drain plug is located on the underside of the engine, while the oil filter may be found near the engine block.

Draining the Old Oil

Place a drain pan beneath the oil drain plug and use a socket wrench to loosen the plug. Allow the old oil to drain completely into the pan. Once drained, tighten the drain plug securely.

Types of Engine Oil

There are different types of engine oils available in the market, each with its unique characteristics and benefits.

Conventional Oil

Conventional oil, also known as mineral oil, is derived from crude oil. It is the most affordable option but requires more frequent changes compared to synthetic oils.

Synthetic Oil

Synthetic oil is chemically engineered for superior performance and longevity. It offers better protection against extreme temperatures and maintains its viscosity for an extended period, making it ideal for high-performance engines.

Synthetic Engine Oil

Synthetic Blend

A synthetic blend combines synthetic and conventional oils, offering a balance between performance and affordability. It provides improved protection compared to traditional crude while being more budget-friendly than full synthetic.

Viscosity Grades

Engine oils are classified based on viscosity grades, which determine their flow characteristics at different temperatures. Common viscosity grades include 5W-30, 10W-40, and 20W-50, with the first number representing viscosity at cold temperatures and the second number at operating temperatures.

How Often Should Engine Oil Be Changed?

The frequency of oil changes depends on various factors, including the type of oil used, driving conditions, and manufacturer recommendations. Typically, it is recommended to change the engine oil every 5,000 to 7,500 miles for conventional oil and every 7,500 to 10,000 miles for synthetic oil.

Signs of Low Engine Oil Levels

It is essential to regularly check the engine oil level to prevent damage to the engine. Signs of low oil levels include illuminated oil pressure warning lights, engine knocking or ticking noises, and visible oil leaks under the car.

Steps to Check and Change Engine Oil

Preparation

Before checking or changing the engine oil, ensure that the car is parked on a level surface and the engine is cool. You will need gloves, a wrench, an oil filter wrench, a funnel, and the appropriate type and amount of engine oil.

Checking Oil Level

Locate the oil dipstick, remove it, and wipe it clean with a cloth. Reinsert the dipstick fully, then remove it again to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick.

Changing Engine Oil

To change the engine oil:

  1. Locate the oil drain plug underneath the car and place a drain pan beneath it.
  2. Unscrew the drain plug to drain the old oil completely.
  3. Remove the old oil filter and replace it with a new one.
  4. Refill the engine with the appropriate amount of fresh oil using a funnel.

Common Mistakes to Avoid When Changing Engine Oil

  • Forgetting to tighten the oil drain plug properly
  • Overfilling or underfilling the engine with oil
  • Using the wrong type or grade of oil
  • Neglecting to replace the oil filter during oil changes

Benefits of Using High-Quality Engine Oil

Using high-quality engine oil offers several benefits, including improved engine performance, better fuel efficiency, reduced emissions, and extended engine life. Investing in premium engine oil can save you money in the long run by minimizing the risk of costly repairs and engine failures.

Environmental Impact of Engine Oil Disposal

Proper disposal of used engine oil is essential to prevent environmental contamination. It should never be poured down the drain or disposed of with household waste. Instead, it should be taken to a designated recycling center or automotive service facility for safe disposal or recycling.

Replacing the Oil Filter

Remove the old oil filter using an oil filter wrench. Before installing the new filter, apply a thin layer of fresh oil to the rubber gasket to ensure a proper seal. Install the new filter by hand, being careful not to overtighten it.

Adding New Oil

Locate the oil filler cap on top of the engine and remove it. Use a funnel to pour in the appropriate type and amount of new oil as recommended by your vehicle’s manufacturer. Check the oil level using the dipstick to ensure it falls within the recommended range.

Checking for Leaks

After adding new oil, inspect the oil drain plug and filter for any signs of leaks. Address any leaks immediately to prevent oil loss and potential engine damage.

Cleaning Up

Wipe off any spilled oil from the engine and surrounding components using a rag. Dispose of the old oil and filter responsibly at a recycling center or auto parts store.

Final Checks

Start the engine and allow it to run for a few minutes to circulate the new oil. Check the oil pressure gauge or warning light to ensure proper oil circulation. Finally, recheck the oil level using the dipstick and add more if necessary.

Dispose of Old Oil Properly

Never dispose of old oil by pouring it down the drain or onto the ground, as it can contaminate soil and water sources. Instead, please take it to a designated recycling center or auto parts store for proper disposal.

Conclusion

Changing your car’s engine oil is a relatively straightforward task that can greatly benefit your vehicle’s performance and longevity. By following these simple steps and performing regular oil changes, you can keep your engine running smoothly for years to come.
