What Colour Is 2 Stroke Oil

Oil is dyed blue to make it easier to recognize it in the gasoline.

Is all 2 stroke oil colored?

A. Color is an identifier only. Oil manufacturers have a choice of colors for 2-cycle oils and some choose not to dye the oil at all. Color is used to help determine if the fuel:oil mix has been made but has no bearing on its application or quality.

Is mixed gas blue?

If gasoline is blue, it is 2-stroke gas, that means it is mixed with 2-stroke oil. Such gas is used for 2-stroke engines, meaning the piston fires every 2 strokes rather than every 4 like most engines. The reason they put blue dye in this oil is to make it easy to tell if it is 2-stoke gas.
