The Caltex Power Flushing Oil works the same way as cheaper monograde oil used for the same purpose. It's not the type of flushing chemical added to your current oil then drained after 5 minutes. IMO, this is a less risky method of flushing. In my experience, it gets a lot of dirt out, but perhaps not as cleanly as flushing with the chemical.
Speedy, is it safe to use flushing chemicals every oil change? Or would that be overkill? When would you recommend we flush using chemicals, and not just ordinary or flushing oil?
They're using mineral oil most probably.
