This value pack pairs Flushing Oil Concentrate with CRD Fuel Enhancer - an engine flush for the oil side and an injector cleaner for the fuel side. Flushing Oil Concentrate restores pristine cleanliness to the oil-wetted parts of the engine, while CRD Fuel Enhancer cleans fuel pumps and injectors and minimises injector rattle. Together they save rebuilds from the common problems affecting diesel and petrol engines.

Sludge and dirty injectors usually arrive together: as oil degrades it leaves deposits through the engine, while fuel varnish blocks injector spray patterns. An engine flush and injector cleaner pack treats both at the same service - flush at the oil change, then dose the fuel at each fill.

Choose the engine flush and injector cleaner pack size to suit the job, from the small pack (treats one 4WD easily) up to the fleet pack for a number of trucks. Buying the two products together makes this engine flush and injector cleaner pack better value than buying separately.
