Hi Gschoen:

___Where did you see that I said the Prius II was not a PZEV?

___I did add that the PZEV based HCH and Accord are cleaner then the PZEV based Prius II. The CAT’s and fuel control systems on the PZEV based Honda’s are more emissions efficient then the CAT(s) and fuel control systems currently available on the Prius II’s. The differing CAT efficiencies will show a Delta in emissions on either LS or HS fuels … The Prius is a Tier II - Bin 3 rated automobile on non LS fuel and a CARB rated PZEV on LS. The Accord and HCH PZEV’s are Tier II - Bin 2 rated on non LS fuel and a CARB rated PZEV on LS fuel.

___In terms of fuel, it is not a specially formulated fuel, it is low sulfur fuel (LS) that lets the PZEV’s really shine. This helps most other PZEV’s and non-PZEV’s clean up their act as well. LS gasoline is available from many states outside of California as well as many stations around the country. BP-Amoco’s Ultimate here in the Chicago area, Green Planet at some Holiday stations in upper WI., and MN., and some Shell’s in MN. to name a few in the Midwest. We in the Chicago/Milwaukee area have the worst fuel of all other then the few specific examples listed above (extremely high sulfur and 10% ethanol laced) if you can imagine that

___Good Luck
