Oil Additive Colorovo RUN FLUSH PB/ON 400 ml

Colorovo RUN FLUSH PB/ON 400 ml is an oil additive formulated for use with petrol and diesel engines. Supplied in a 400 ml dose, it is intended to be added to the engine oil to assist in loosening and suspending sludge and deposits, improving circulation of the oil during maintenance or prior to an oil change. The formulation is suitable for routine servicing and for pre-flush treatments that prepare the lubrication system for fresh oil.

Advantages

This oil additive helps dissolve and suspend accumulated deposits and varnish in engine oil pathways, crankcase areas and oil galleries. By promoting better circulation and cleaner oil flow during the service interval, it can make oil and filter changes more effective. The 400 ml format is sized for single-treatment use in a range of passenger vehicles and light commercial engines that accept oil additives for cleaning purposes.

Suitable for

• Petrol engines (PB) requiring a pre-flush or in-service cleaning treatment
• Diesel engines (ON) needing assistance to remove sludge and deposits
• Routine maintenance and oil change procedures where improved oil circulation is desired
• Engines with moderate deposit build-up before mechanical cleaning

When it may not be suitable

This product is not a substitute for mechanical repairs and will not fix worn bearings, severe varnish baked onto components, or hardware failures. It is intended for use with compatible engine oils; compatibility should be confirmed with the oil manufacturer if uncertain. Vehicles under warranty should use additives only if recommended by the vehicle maker or permitted under warranty terms.

Key specifications

• Formulation type: oil-based additive for cleaning and flushing
• Intended engine types: petrol and diesel
• Volume: 400 ml single-treatment pack
• Primary function: loosen and suspend sludge, deposits and varnish for removal
• Application timing: added to engine oil during running-in period before oil change or during service

How to use

Add the entire 400 ml bottle to the engine oil according to the vehicle manufacturer’s instructions or the product label directions. Run the engine at normal operating temperature for the recommended period (typically specified on the bottle) to allow the additive to circulate and act on deposits. After the treatment interval, drain the oil and replace the oil filter, then refill with fresh engine oil to the specified level.

What to consider before purchase

• Confirm compatibility with the vehicle’s engine oil and any manufacturer restrictions on additives
• Assess the level of internal deposit build-up—severe mechanical issues may require specialist cleaning
• Check the recommended treatment volume for your engine to ensure a single 400 ml pack is sufficient

Usage recommendations

Use as part of routine maintenance or as a pre-flush prior to an oil change. Always warm the engine to operating temperature before treatment and follow up with a full drain and new oil and filter to remove suspended contaminants.
