As a fuel oxidizes, it may form organic acids and polymers that may cause fuel system deposits, fuel filter clogging, and fuel system malfunctions. Once auto-oxidation of the fuel begins, there is no way to reverse the effects. Although continued acid formation cannot be stopped, the process may be slowed by the addition of anti-oxidants. Oxidation Stability is performed in accordance with EN 15751.
ASTM D6751 Requirement: a minimum oxidative stability of 3 hours.
