I've been using Techron/Progard periodically over the
past 5-6yrs on 2 of my cars.  It 'seems' to make 
a difference, sometimes more than others.  Lately, 
it doesn't appear to help my occasional pinging on 
heavy acceleration on either car, and I almost 
always fill up with Chevron.  [Going to midgrade octane
helps, but that's just masking my problem, if it is
a problem].

QUestion is:  has anyone physically inspected
their pistons/valves before/after treatment?  Can
one see anything by shining a light down into the
sparkplug hole?  

I find it hard to believe the pictures I see on
the little cardboard packaging that comes with
each bottle.  The before and after a single treatment
results seem exaggerated.
