Ravenol Professional Engine Cleaner is a high-performance engine flush designed to safely remove sludge, varnish and carbon deposits from petrol and diesel engines before an oil change. By cleaning the internal oil galleries, piston rings and hydraulic components, it helps restore proper oil flow, improve engine efficiency and prepare the engine for fresh oil.
This intensive cleaner uses advanced surfactants to break down harmful deposits that build up over time due to short journeys, delayed oil changes or general engine wear. Once drained, contaminants leave the engine with the old oil, allowing the fresh oil to perform at its best.
For best results, Ravenol strongly recommends using this cleaner when switching to Ravenol engine oil for the first time.
Suitable For
- All petrol and diesel engines
- Vehicles with or without catalytic converters
- All mineral, semi-synthetic and fully synthetic oils
- Cars, light commercial vehicles and marine applications
When to Use
- If black sludge is suspected
- If hydraulic tappets are rattling
- If oil changes have been delayed
- For visibly soiled engines or heavily used oil
How to Use
- Warm the engine to operating temperature
- Add the entire contents of the can to the old engine oil
- Do not allow the oil level to drop below the minimum mark
- Run the engine at idle for 15–20 minutes
- Drain the oil completely
- Replace the oil filter
- Refill with the correct grade of Ravenol engine oil
Key Benefits
