TESTING PETROL
CORROSIVE CONTENT PRIVATE INVESTIGATIONS Large purchasers of petrol often make their own testa to ensure that a certain standard of volatility and purity is maintained. The Auckland City Council applies tests to petrol used in its large fleet of trucks and buses. In the valuation of motor-spirit the main considerations arc the distillation range, the aromatic content and freedom from corrosives. Spirits rich in aromatics arc not as liable to detonate or “p ; nk” as those with low aromatic content. During relining, petrol is treated first with sulphuric acid and then with caustic soda. The acid treatment removes certain gum-forming substances, and the caustic soda is used to remove traces of the acid. Should acid remain, corrosion of the gauze strainers and of the carburetter float will result.
