• We reccomend two treatments for engines with the mileage of over 40,000 kms (25,000 miles).
  • You are advised to carry out the first one approximately 400 km (250 miles) before an oil change.
  • If the oil capacity is larger than 9 litres, you can combine G4 and G6 products and use in an engine that contains 10 litres of oil; with two G6 packages, you can treat an engine that contains 12 litres of oil etc.
