Plug Reading

[Len Sabatine]

  Yep , and  to that end , additive packages vary per fuel provider, add to 
the art
  of reading spark plugs. Spec additive packages provide us with end 
results of what
  they do to plug coloration, from what I've observed along the way. Some 
blends
  tend to rapidly deposit the metallic component[ s ] on insulators, 
tending to muddy
  the tune up in short order. Others don't color readily /easily , Fuel 
itself is a variable
  in the tuning mix. Fuels dosed with  aromatics can look fat , when in 
fact, may be
  a tad lean , as a variable. GM deals with these issues in calibrations as 
well , it's a
  big variable producing vehicles that work anywhere under nearly any 
conditions.
