Why buyers look at this type of cleaner
An ester-based engine oil cleaner for petrol and diesel engines, made to remove sludge, varnish and deposits before fresh oil is added.
Oilsyn ReleaseTech is a long-life engine oil cleaner and flush for petrol and diesel engines. It is used to help dissolve sludge, varnish and other deposits that build up inside the engine, with the aim of leaving a cleaner surface before fresh oil goes in.
The formula uses Oilsyn’s ReleaseTech cleaning and dispersant technology, along with Group VI ester and a friction modifier. The listing says it is ashless, non-corrosive and safe to keep in the oil, with compatibility for all petrol and diesel engines.
- Helps remove particulates, sludge and varnish from the engine oil system.
- May assist with deposit removal around seals and internal surfaces.
- Can be used as part of preparation before Oilsyn Veloyn or NanoC5.
- Supplied in a 250ml bottle, which is the key size detail given in the listing.
Points to check before buying
- Make sure an engine flush or cleaner is suitable for the maintenance job you have in mind.
- Check your vehicle’s oil capacity and the product instructions before use.
- Use the cleaner only in line with the guidance on the bottle or listing.
The product is described as a cleaner rather than a repair treatment, so it is best treated as part of routine engine maintenance rather than a fix for mechanical faults.
