Condition Flash Point (°F) Fire Risk Level Fresh Motor Oil 400 – 450 Low Heated Motor Oil (Degraded) Below 400 Moderate to High Oil-Soaked Rags Very Low (Spontaneous Combustion) High. Motor oil should be kept in tightly sealed, original containers or approved safety cans, away from direct heat sources and ignition materials.
Debunking the Motor Oil Combustibility Myth: Understanding Fire Risk
This distinction depends on the specific temperature thresholds required to ignite the substance, which differ significantly from materials that ignite instantly at room temperature. This high thermal stability is why motor oil is used in hydraulic systems and industrial applications where fire resistance is a priority, though this does not mean it is fireproof.
In a garage or workshop, storing oil away from spark-producing tools and maintaining clean floors to prevent the buildup of oil-soaked rags is crucial. Because it requires such high heat to ignite, it is categorized as combustible rather than flammable.
Debunking the Motor Oil Combustibility Myth: It's Combustible, Not Flammable
The short answer is complex, as motor oil is combustible rather than strictly flammable in its standard form. When oil is heated to its smoke point, it begins to break down chemically, producing volatile compounds that can ignite more easily.
