Solvents and primers are not an effective way to correct oil damage: they provide only a short-term solution to clean the area and help sealcoat adhere to damaged pavement. When oil penetrates an asphalt surface, the only way to permanently correct the issue is to remove the oil-saturated asphalt.
Test The Oil Spot to See if it Needs Repair
If an oil spot is new (less than 3 days old), it may not have had time to absorb into the pavement. Try washing the oil away using hot water, detergent and a soft broom. Once you’ve cleaned the oil as best you can, test the spot by scratching it with a screwdriver. If the pavement cracks or crumbles in any way, the material is already breaking down, you’ll need an infrared pavement patch.
