It is aimed at owners of gasoline and diesel 4-stroke engines who need a gentle but effective way to dissolve lacquer, isolate contaminants and restore engine smoothness before fresh oil is added. The single biggest reason to buy is straightforward: it cleans the engine interior quickly and safely so the subsequent oil change delivers maximum benefit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy to use:\u003c\/strong\u003e Add the flush to the existing engine oil, run at idle for 10 minutes and then drain, which keeps the procedure simple and fast.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective cleaning:\u003c\/strong\u003e Formulated to dissolve sludge and lacquer and to isolate solid particles and liquid contaminants so they can be removed with the used oil.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGentle on materials:\u003c\/strong\u003e The formula is neutral to seals and other engine materials so it will not degrade installed components during the short cleaning cycle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalytic converter compatible:\u003c\/strong\u003e Safe for vehicles with catalytic converters, avoiding downstream system concerns when used as directed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestores performance:\u003c\/strong\u003e Customers report improved smoothness, reduced engine noise and better responsiveness after treatment and an oil change.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is best for private owners and small workshop technicians who perform routine maintenance on 4-stroke gasoline or diesel engines and want a cost-effective way to remove internal deposits before an oil change.
