How to Use Engine Internal Cleaner?
2 Answers
Engine internal cleaner is used by following these steps: 1. Add the cleaner to the engine oil before an oil change to flush out harmful sludge along with the old oil; 2. Add new engine oil; 3. Add an engine super additive protector product, then start the engine and let it idle for a period of time; 4. Turn off the engine, drain the old oil, replace the oil filter, and add new oil. Engine internal cleaner can remove residual dirty sludge from the engine oil passages and, to some extent, clean carbon deposits from the piston rings and ring grooves, providing practical maintenance benefits for the engine.
I started using engine flush last year, and the whole process was quite straightforward. First, make sure the engine is warm before shutting it off—don’t do it when the car is cold, just a few minutes of driving is enough. Then, open the engine oil cap, pour in the entire bottle of flush, tighten the cap, and start the car to let it idle for 10 to 15 minutes—don’t drive it, just wait in place. During this time, the flush will circulate and dissolve internal sludge. After the idle period, turn off the engine immediately, drain the old oil, replace the oil filter, and refill with fresh oil. I used a well-known brand, and the manual recommends doing this every 20,000 kilometers. The benefits are noticeable: my car accelerates more smoothly, fuel consumption has dropped slightly, and the engine runs much quieter. Just be careful not to use low-quality products, as they might corrode engine parts. The whole process takes about 20 minutes, making it perfect for weekend DIY maintenance.
