If you are experiencing blue exhaust smoke on start-up and an increase in oil consumption, it is likely to be caused by leaking valve stem oil seals. Rislone High Kilometre Oil Seal Repair is designed to rejuvenate and reseal old, hardened and shrunken valve stem oil seals commonly found on older vehicles or those with higher kilometres. The formula is reinforced with synthetic polymers that create a polymeric film around seals to prevent excess oil from passing the seal, reducing exhaust smoke and oil consumption. Rislone High Kilometre Oil SealRepair can be used in all vehicles including petrol, diesel, and LPG. It is suitable to mix with all oil types including conventional mineral, semi-synthetic and full synthetic oils. Dosage: One bottle treats oil capacity from 4 litres to 6 litres. Use bottle for oil capacity from 2 litres to 3.9 litres. For larger systems use 1 bottle for every 5 litres. On 4-Stroke ATV, Motorcycle and small engines, including wet clutch applications, use approximately 100 mL per litre of oil capacity.
