Description
Overview:
The STP Engine Flush 450ml is a solvent-based cleaning additive designed to clear harmful sludge and varnish-like deposits from inside four-stroke petrol and diesel engines before an oil change. Supplied in a durable ring-pull metal tin for straightforward pouring, it circulates with the old oil to loosen and suspend contaminants so they drain out more completely. This helps restore clean oil flow to vital components and supports smoother running after fresh oil is added. Suitable for cars, vans, light commercial vehicles, and machinery using conventional four-stroke engines, it is a practical choice for routine servicing across road and site equipment. Use as directed by the manufacturer as part of a standard oil and filter change.
Key Features:
- Removes built-up sludge and deposits to aid cleaner oil circulation
- Suitable for both petrol and diesel engines across road and plant use
- 450ml ring-pull tin for easy opening and controlled pouring
- Helps improve engine smoothness and responsiveness after servicing
- Supports more effective oil changes by suspending contaminants for drain-down

Typical Applications:
Used immediately before an oil and filter change in cars, vans, 4x4s, and light commercial plant. Suitable for four-stroke engines in generators, compressors, and site equipment where an oil change is due. Ideal for engines that have experienced frequent short trips, extended drain intervals, or heavy-duty use that can encourage sludge formation.
