 Larry,
 << Any time you mix avgas with jet fuel it becomes milky. So always check
your fuel!!!>>
 The color and clarity were normal. I check fuel after every fill-up and
before each first flight of the day.  I drained the rest into an open 55
gallon drum for disposal and it looked like regular Avgas.  This was back in
'99.  Have additives been added since that time to cause the milky appearance?
