Properties of Regular and Super Unleaded Automotive Gasolines (Ottawa/Hull Area-Summer, 1979) (Proprietes des Essences Auto de Types Sans Plomb Regulier et Super (Region Ottawa/Hull-Ete, 1979)

摘要

Unleaded, automotive, summer grade gasolines, both regular (type 2) and super (type 1), sold in the Ottawa/Hull area by the major oil companies are all excellent in quality. They meet requirements of CGSB Standards 3-GP-5 and 3-GP-5Ma for Unleaded Automotive Gasoline, except for some Reid vapour pressure values and one lead content that marginally exceed limits. The tested gasolines have nil or negligible lead and phosphorus contents indicating excellent protection against catalyst poisoning. Most gasolines have manganese, probably as the methylcyclopentadienyl manganese tricarbonyl antiknock agent. (Author)
