The car engine is known as the "heart" of the vehicle, and the oil is the blood that flows in this heart, and its importance is self-evident. Regular oil changes not only ensure smooth engine operation and reduce wear, but also extend engine life. However, how to properly change the oil is not familiar to all car owners. This article will introduce the whole process of changing the engine oil in detail, and help car owners take care of the "heart" of their car with their own hands, so that it can be kept and replaced forever.
1. Preparation before changing the engine oil.
1.Choosing the right oil: First, consult your vehicle's manual to find out the type, viscosity grade, and capacity recommended by your vehicle manufacturer. There are many types of motor oils on the market, including mineral oil, semi-synthetic oil, and fully synthetic oil, and car owners should choose the most suitable oil according to their vehicle operating conditions, driving environment, and budget.
2.Tools & Accessories Preparation: Gather the tools you need to change your oil, including wrenches, funnels, oil drums, oil filter wrenches, new oil filters, and protective equipment such as gloves and old newspapers.
Second, the specific steps to change the engine oil.
1.Preheat the engine: Start the engine and let it run for about 5-10 minutes before changing the oil to allow the oil to pre-heat up and flow, allowing the old oil to drain more thoroughly.
2.Place the oil pan tray: Place an oil pan tray under the vehicle to catch the old engine oil that is about to flow out.
3.Unscrew the drain bolt: Use a wrench to unscrew the drain bolt and let the old oil flow out slowly. Note that the oil temperature is high, so be careful of burns when operating.
4.Replace the oil filter: While the old oil is still coming out, use an oil filter wrench to unscrew the old oil filter, then apply the new oil to the seal of the new filter, install it in place, and tighten it properly.
5.Drain the old oil: When the old oil is almost drained, wipe the drain bolts with a clean cloth before screwing them back. After that, start the engine slightly for about 10 seconds to drain the remaining oil, then turn off the engine and re-unscrew the oil drain bolt to make sure all the oil is drained.
6.Add new oil: After closing the drain bolt, add new oil to the engine through the oil port. Pour slowly with the help of a funnel while checking the oil level against the dipstick to ensure that it is added within the specified scale.
7.Check the oil seal and clean up the site: confirm that there is no oil leakage in the oil filter, the oil port cap is tightened, and the old oil in the oil pan tray is properly disposed of, and the oil replacement can be completed.
3. Precautions after changing the oil.
1.Start the engine and check: After the change, start the engine, let the new oil circulate for a few minutes, then stop again, pull out the dipstick to check the oil level, and if necessary, make up the appropriate amount.
2.Change your oil regularly: Follow the vehicle manufacturer's recommended oil change cycle, which is usually every 5,000-10,000 kilometers or six months to a year. At the same time, it should also be appropriately adjusted according to the use of the vehicle and the driving environment.
3.Check the oil condition regularly: Between oil changes, car owners should regularly check the oil level and color, and if they find that the oil color has turned black, the viscosity has increased, or the oil volume has decreased, they should replenish or replace it in time.
By changing the engine oil correctly, the owner can not only ensure that the engine of your car is always in the best working condition, but also effectively prevent all kinds of failures caused by oil problems, so that your car's heart will always be young and accompany you through a longer journey.
