Abstract
From time to time the authors have been receiving enquiries from engine builders and operators about the reason why diesel engine oils or gas engine oils have both basicity and acidity. In order to respond to the enquiry, the principle of acidity and basicity measurements in color-indicator titration of aqueous solutions is explained. Similar methods are used to determine neutralization values of non-aqueous solutions such as petroleum products, even though electrometric titration is more suitable for darker-colored oils and used oils. The practical importance of neutralization value tests is also discussed, with particular reference to diesel and gas engine oils.
