A colloid is a heterogeneous mixture whose particle size is intermediate between those of a solution and a suspension. The dispersed particles are spread evenly throughout the dispersion medium , which can be a solid, liquid, or gas. Because the dispersed particles of a colloid are not as large as those of a suspension, they do not settle out upon standing. The Table below summarizes the properties and distinctions between solutions, colloids, and suspensions. Particle size: 0. Particle size: nm, dispersed; large molecules or aggregates.
Particle size: over nm, suspended; large particles or aggregates. May either scatter light or be opaque. Colloids are unlike solutions because their dispersed particles are much larger than those of a solution. The dispersed particles of a colloid cannot be separated by filtration, but they scatter light, a phenomenon called the Tyndall effect. When light is passed through a true solution, the dissolved particles are too small to deflect the light.
However, the dispersed particles of a colloid, being larger, do deflect light. The Tyndall effect is the scattering of visible light by colloidal particles. All three are examples of colloids. Suspensions may scatter light, but if the number of suspended particles is sufficiently large, the suspension may simply be opaque and the light scattering will not occur.

No it is not a colloid. Colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspension. Technically it could be any of those, depending on the type of cooking oil.
