especially suitable for use in high mileage or
older vehicles. The special additives work in all
oils to stop leakage caused by hard and brittle old
seals, and help recover “like new”performance.
- Reduces oil leaks by softening and expanding old
seals
- Improves lubrication, reduces oil consumption
and exhaust smoke in worn engines
- Increases engine compression and reduces wear.
- Cushions regular impact areas such as tappets,
cams and gears
