The Problem With Oil
Motor oil, transmission fluid, and hydraulic fluid all contain solvents that soften and dissolve asphalt binder. Left untreated, they create dark, spongy spots that continue to spread and eventually fail entirely.
Sealcoat will not adhere to oil-contaminated pavement. Applied over an untreated spot, the sealer will lift, blister, and expose the failure.
Correct Treatment
- Scrape and remove loose or soft material
- Detergent scrub with a heavy-duty degreaser
- Rinse and dry completely
- Apply oil-spot primer — a specifically formulated bonding primer, not standard sealer
- Allow cure per manufacturer instructions
- Sealcoat the entire lot in the normal sequence
When The Spot Is Too Far Gone
If the pavement beneath the oil is soft, spongy, or has visible dissolution, primer will not save it. That section needs a saw-cut patch before sealcoat.
Prevention
- Address vehicle leaks promptly
- Place drip trays under known-leaking equipment
- Sweep quarterly to remove residue
- Keep dumpster and delivery zones on concrete pads where possible

Frequently Asked Questions
Can I clean oil spots myself before the sealcoat crew arrives?
Yes — a stiff broom, dish soap, and rinse will remove surface residue. Deep saturation still needs primer.
Does kitty litter really absorb oil?
Fresh spills, yes. Soaked-in stains, no — those need chemical or mechanical treatment.
Will the spot come back?
Only if the source of the leak is still active. Fix the leak, and the treated spot stays sealed.
