1. Drain oil except one quart, or you can drain all the oil and add one quart of new oil. (Starting with a NEW oil filter is recommended).
2. Add the remainder as kerosene, approx. 3 quarts.
3. Start the engine. DO NOT REV THE ENGINE
4. Let it run until warm, not HOT, just warm. About 5-10 mins.
5. Drain the entire contents, during or just after you can continuously pour kerosene into the engine until it comes out clear...
6. Add one quart oil, 3 quarts kerosene.
7. Run the engine again until slightly warmer. DO NOT REV THE ENGINE
8. Drain the entire system.
9. Again if you think it requires, you can pour Kerosene into the NON-running engine as it drains out until it comes out clear.
10. Pour about one quart of oil and let it run out of the oil pan.
11. Add your favourite oil/oil filter.(replace oil pan plug...)
12. Run engine until it’s at operating temperature. Check to make sure it is running ok.
13. Optional...You can drain the system one last time and add new oil filter and oil...

This does a great job...

The residue that comes out should be quite black and a thin liquid...Chunks or sludge should be dissolved...

Flushing engine with kerosene gives very good results. Engine oil flush additives are basically kerosene too, put them in a glass bottle and compare..

However, there is one exception for the engine flush: high mileage cars. In an old engine you really don't want to remove all the deposits. Some of these deposits help seal rings, lifters and even some of the flanges between the heads, covers, pan and the block, where the gaskets are thin. I have heard of engines with over 180000 miles that worked fine, but when flushed it failed in a month because the blow-by past the scraper ring (now really clean) contaminated the oil and screwed the rod bearings. So having said that …

Disclaimer: I am not responsible for the out come of this procedure... do so at your own risk.. IE you decide if your car is of insufficient mileage to expect a good result..
