OIL BASED SEALERS ARE A FARCE. There is no such thing as a oil based pavement sealer. Pavement sealing is needed to lock / seal the pre-existing oils into the pavement to keep them from being pulled out by the UV Rays of the sun. Once the pavement has been neglected to the point of theoretically needing oil added or infused back into the pavement the damage has already been done. Any attempts to introduce oils back into the pavement are futile attempt to save the pavement which will result in excess oil laying on the surface of the pavement. This excess oil laying on the surface will soon begin to turn the pavement into a mush. A prime example of this type of damage would be the oils stains on a commercial parking lot. If you were to shove a screw driver into one of these stains you would then see first hand the amount of surface softening that results from oil laying on the surface of the pavement.
