how to flush engine using off-the-shelf engine flush additives?
Is flushing engine safe or not? I read the net and read conflicting reports on the effectiveness of it. Some would say it would even be harmful to the engine as it dislodges all the build-up dirt.
Also is there a proper way of performing an engine flush using off-the-shelf additives?
I was thinking:
1. put engine flush additive.
2. run engine
4. put some cheapest motor oil I could fine
5. run engine
6. put engine flush additive
7. run engine
9. put proper motor oil and filter
I only thought of putting a cheap motor oil so any sludge that wasn't removed in the first drain will hopefully come out this time around.
