Leak Doctor is a multi-functional oil additive especially suitable for use in high mileage or older vehicles. The special additives work in all oils to stop oil leakage caused by hard and brittle old seals, and help recover “like new” performance.
Leak Doctor also improves oil viscosity at high temperatures, and contains soluble molybdenum to reduce engine wear.
- Reduces oil leaks by softening and expanding old seals.
