Engine Stop Leak reduces annoying oil leaks in all petrol, diesel and LPG engines. Use this product if your car has any of the following symptoms: loses or leaks oil, blows blue smoke at start-up, on take-off after a period of idling at traffic lights, or when decelerating downhill.
NOTE: Can be used to control leaks in manual gearboxes and differentials (See directions for use).
Add 1 bottle for every 5 litres of engine oil. Shake bottle and add contents to engine oil. Idle engine for at least 1 minute. Use with every oil change. To reduce gearbox and diff oil leaks, add 60 ml per litre of oil.
NOTE: It may take 14 days or 500 km to achieve maximum benefits. Excessively worn or damaged seals may not respond and will require replacement.
For advice, contact a Poisons Information Centre (Phone e.g. Australia 131 126; New Zealand 0800 764 766) or a doctor (at once).
Running a very thick oil can sometimes cause issues in modern engines. An area that is often overlooked when oil comsumption is a problem is hardened valve stem seals. Oil will bypass hardened seals and allow oil into the combustion chamber via the valve stems. Consumption as high as one litre per thousand kms can be caused by valve stem seal leakage. Nulon Engine Stop Leak can rejuvenate hardened valve stem seals and should be used before moving to a thicker engine oil.
Yes, Nulon engine treatments (Worn Engine Treatment,E20 Engine Treatment,Long Term Engine Treatment,Passenger Car Diesel Engine Treatment, Heavy Duty Diesel Engine Treatment etc) will reduce cylinder blowby and reduce crankcase pressures. Engine Stop Leak will also rejuvinate hardened oil seals
White exhaust smoke on morning start-up is generally caused by leaking valve stem seals. Engine Stop Leak would be the best product to use to reduce this smoke.
Nulon Engine Stop Leak is an additive that can rejuvenate elastomer type engine seals that have hardened or shrunk. "rear main" and "timing cover" seals are typical areas for external oil leaks.
No, oil changes should still occur at the intervals set by the vehicle manufacturer.
No, all Nulon engine treatments are compatable with synthetic and mineral oils
It will dilute the engine oil, effecting its viscosity and ability to protect vital components. We recommend replacing engine oil and filter before driving.
Nulon ani-wear Engine Treatments based on PTFE can be added to engine oil at any time but are best added to new engine oil after an oil change. Please follow directions of use for the Nulon Engine Treatment products to ensure your engine receivesthe best possible protection from wear and friction.
No, all engine treatment products should only be used as per dosage recommendations as per directions. We would also recommend to not use more than one additive in an engine at one time.
Worn Engine Treatment,E20 Engine Treatment, Passenger Car Diesel Engine Treatment and Heavy Duty Diesel Engine Treatment are recommended at each oil change, Long Term Engine Treatment can give protection for up to 80,000km on certain vehicles.
It is recommended to only use one Nulon engine product at each oil change.
This depends to the fuel type (petrol or diesel) and also the age and mileage on the vehicle. Worn Engine Treatment for high mileage engines with some wear, E20 Engine Treatment for engines in good condition, Long Term Engine Treatment as a long term treatment. Small capacity diesel engines should use Passenger Car Diesel Engine Treatment, while for larger diesel engines use Heavy Duty Diesel Engine Treatment.
