How to clean engine oil
Engine oil cleaning is an important part of vehicle maintenance. Regular cleaning can effectively extend engine life and improve performance. This article will introduce in detail the steps and precautions for engine oil cleaning, as well as related technical discussions on recent hot topics.
1. The necessity of engine oil cleaning
After long-term use, engine oil will accumulate impurities, sludge and carbon deposits, affecting the lubrication effect. If not cleaned in time, it may lead to increased engine wear, increased fuel consumption or even failure. The following are common signs of oil contamination:
| Pollution type | Symptoms |
|---|---|
| Sludge accumulation | The color of the engine oil turns black and its fluidity becomes poor |
| Carbon deposit formation | Engine power decreases and noise increases |
| metal particles | Tiny metal shavings visible in engine oil |
2. Engine oil cleaning steps
To clean engine oil, you need to follow the following steps to ensure safe and effective operation:
| steps | Operating Instructions |
|---|---|
| 1. Warm up the engine | Start the vehicle and run it at idle speed for 5-10 minutes to increase the engine oil temperature. |
| 2. Drain old oil | Unscrew the oil drain bolt and drain the old oil completely |
| 3. Add cleaning agent | Pour in special engine cleaning agent and run at idle speed for 10-15 minutes |
| 4. Discharge again | Discharge the waste liquid after cleaning to ensure that there is no residue |
| 5. Replace the oil filter | Install a new oil filter to avoid secondary pollution |
| 6. Fill in new engine oil | Add new engine oil that meets specifications according to standard amount |
3. Recent hot topics and discussions related to engine oil cleaning
In the past 10 days, hot topics about engine maintenance on the Internet have mainly focused on the following aspects:
| hot topics | focus of discussion |
|---|---|
| New energy vehicle oil maintenance | Do hybrid vehicles need traditional engine oil cleaning? |
| Environmentally friendly cleaning agent | Market feedback on biodegradable cleaning agents |
| DIY cleaning risks | Common problems caused by car owners’ own operations |
4. Precautions for engine oil cleaning
To avoid problems during cleaning, pay attention to the following:
| Things to note | Reason explanation |
|---|---|
| Avoid frequent cleaning | Excessive cleaning may damage engine seals |
| Choose regular products | Inferior cleaning agents may cause oil lines to become clogged |
| Hot car operation | Impurities are difficult to completely remove when the car is cold |
5. Professional advice and user FAQs
Based on recent discussions on automotive forums, we have compiled three frequently asked questions:
| question | Expert answers |
|---|---|
| Engine noise after cleaning | There may be detergent residue, so it is recommended to rinse twice. |
| How often should you clean it? | It is recommended that ordinary vehicles be cleaned every 20,000 to 30,000 kilometers. |
| Can diesel fuel be used instead of cleaning agent? | It is strictly prohibited to use it as it will corrode the seals. |
6. Future technology development trends
Judging from recent industry trends, engine oil cleaning technology is developing in two directions:
1.Disassembly-free cleaning system: The high-pressure circulation device is used to achieve deep cleaning without disassembling the engine. It is currently used in some high-end models.
2.Intelligent monitoring system: Real-time judgment of cleaning needs through the oil quality sensor to avoid excessive or insufficient maintenance operations.
Through regular and standardized engine oil cleaning and maintenance, combined with correct operating methods, the working efficiency and service life of the engine can be significantly improved. It is recommended that car owners refer to the vehicle manual and develop a reasonable maintenance plan based on actual usage conditions.
