For the initial treatment, add to engine oil at a ratio of between 2.5% and 5% of sump capacity (i.e. between 25ml and 50ml per litre of oil). In automotive applications this treatment will last for no longer than 25,000 miles / 40,000 km or 5 oil changes (whichever is the sooner). Manufacturers’ recommended frequency of oil changes must be observed but there is no need to add any more ACTIV8 Friction Reducer until 25,000 miles / 40,000 km or 5 oil changes after the fi rst treatment. Then another treatment with half the original quantity will maintain the required ratio for a further 25,000 miles / 40,000 km or 5 oil changes. The survival of the effects of ACTIV8 Friction Reducer can differ under different operating conditions. For example, the higher the load and/ or temperature, the quicker the residual effect of ACTIV8 Friction Reducer will be reduced.
For example, the reapplication of ACTIV8 Friction Reducer is recommended once every second oil change (half of the original quantity), although many use it in every oil change.
For example, for all vehicles operating under constant maximum load conditions such as light commercials or towing, it is known that ACTIV8 Friction Reducer usually requires more frequent reapplications.
