Here's How Engine Flushing
"Power-Flushes" Harmful Sludge And Abrasives Out Of Your Engine
1. Heated detergent solution is injected under pulsating pressure through the oil filter port.

2. Engine Flushing Solution flows through the engine's lube-oil system, power-flushing out sludge and abrasives.

3. The oil pump pickup screen is backflushed with sludge-dissolving detergent solution

4. Dissolved sludge, varnish and abrasives are vacuum extracted out of the engine.
