Concentrated oil stabiliser designed to mix with engine oil and extend effective service life. User reports say it reduces startup rattle and smooths engine operation.
Longer Oil Life – thanks to oil stabiliser action
Label claims the stabiliser increases oil life by at least 50 percent, by blending with existing engine oil to preserve its useful properties. Application is intended during normal oil service to extend effective oil intervals.
Fewer oil changes are needed, which is useful for drivers who cover high mileage. Extended intervals reduce routine maintenance time and frequency of top-ups.
Reduced Oil Consumption – with improved oil retention
Product description lists reduced oil consumption as a primary benefit, aimed at engines that tend to consume oil between services. The stabiliser is intended to address oil loss mechanisms that lead to frequent top-ups.
Lower oil usage means fewer emergency top-ups and less monitoring between services. This helps owners keep engines running closer to scheduled maintenance.
Quieter Start-ups and Smoother Running – with anti-dry start effect
Elimination of dry starts is specified in the description, and multiple user reviews report stopping timing chain rattle and reducing startup noise after use. The effect is reported most clearly on high-mileage and ageing engines.
Quieter, smoother cold starts improve driving comfort, especially in older vehicles. Reduced rattles and smoother idling can make an ageing engine feel revitalised.
