Vader as he goes by here also frequents a couple Impala/Caprice forums I am active on. Haven't seen him around lately. Since then whenever someone starts spouting off bad oil info on one of the other car forums I visit I point them straight here. Most guys go by the "always worked for me" theory and the UOA section is the only way to prove what actually works. These same guys want dyno numbers for parts but then ask for no proof as to how oil is working the UOA section really opens eyes.
