Hindi ata volatile ang oil sa normal na takbo ng makina sa 60 centigrade. Hindi mageevaporate ang lube oil base stock. Ang gamit sa automotive engine oil ay halimbawa 500 SN may flash point na 237 centigrade.
AP/E SN 500.

Pag umabot ng 200 centigrade ang engine oil temperature mo, magdasal ka na men.

Ang ZDPP anti-wear lang ito, ika nga e pampadulas lang ng bakal.
