WYNN’S ENGINE FLUSH - After an oil change, the new oil in the engine frequently turns black after a few hundred kilometres. This is because the new oil, charged with additives, goes to work to remove the sludge and varnish that remained in the engine when the dirty oil was drained. The sludge causes sticky piston rings and hydraulic valve lifters. The new oil becomes contaminated and the additives are depleted. Prevent this by pouring WYNN’S ENGINE FLUSH into the oil before draining it. Drive the vehicle for 30 - 100km, drain the oil, replace the filter and add fresh oil. WYNN’S ENGINE FLUSH helps the new oil do a better job protecting the engine.
