Are brands different?
Yes. The above specifications are intended to ensure minimal quality standards are maintained, however as well as the fuel hydrocarbons, the manufacturers add their own special ingredients to provide additional benefits. A quality gasoline additive package would include:- * octane-enhancing additives ( improve octane ratings ) * anti-oxidants ( inhibit gum formation, improve stability ) * metal deactivators ( inhibit gum formation, improve stability ) * deposit modifiers ( reduce deposits, spark-plug fouling and preignition ) * surfactants ( prevent icing, improve vaporisation, inhibit deposits, reduce NOx emissions ) * freezing point depressants ( prevent icing ) * corrosion inhibitors ( prevent gasoline corroding storage tanks ) * dyes ( product colour for safety or regulatory purposes ). During the 1980s significant problems with deposits accumulating on intake valve surfaces occurred as new fuel injection systems were introduced. These intake valve deposits (IVD) were different tha
