The video discusses three methods of engine flushing: disassembling and washing the engine with special chemicals, gentle flushing with high-viscosity oil, and aggressive flushing with a special liquid. The speaker also experiments with using dimexide, a pharmacy-bought substance, to clean a piston and remove sludge. Although dimexide effectively removes sludge, it corrodes aluminum and paint, making it a risky choice for engine decarbonization. The speaker warns against using dimexide in the engine due to its negative effects on aluminum and advises against washing the engine with it. Instead, they recommend using it to clean the engine from the outside with a high-pressure washer.
Here are the key facts extracted from the text:
1. The engine should not be started when it's in a dirty state.
2. Regular oil changes are necessary to keep the engine clean.
3. Oil changes should be done according to the seasons or mileage.
4. A dirty engine can cause problems with oil circulation and engine performance.
5. Engine flushing can be beneficial, but it's not always necessary.
6. There are three main methods of engine flushing: disassembling the engine, gentle flushing, and aggressive flushing.
7. Gentle flushing involves draining old oil and replacing it with new oil that has a high package of detergent additives.
8. Aggressive flushing involves using a special liquid to clean the engine.
9. Dimexide can be used to clean the engine, but it must be used with caution.
10. Dimexide crystallizes at 20 degrees Celsius and must be heated before use.
11. Dimexide can corrode aluminum and should not be used on aluminum parts.
12. Dimexide can dissolve paint and should not be used on painted surfaces.
13. The engine should be warmed up before using dimexide for decarbonization.
14. The procedure should not take longer than 20 minutes to avoid freezing.
15. If the engine is very clogged, washing may not be effective and can cause problems with the filter and engine.
16. It's not recommended to use dimexide in the engine due to its negative effect on aluminum.
17. Dimexide can be used to wash the engine from the outside.
18. A high-pressure washer can be used with dimexide for external washing.
19. White spirit did not work effectively in the experiment.
20. The conditions for the experiment may have been different, affecting the results.
