I would not recommend to flush yr engine at all...... you will wash off all the carbon deposits that have built up over its life.... (primarily is good)
leaving your car to sound like a diesel......
Plus taking all those crystalized deposits into yr bearing shells ...
just order a new engine same time you pay for yr oil flush...
