By improving seal pliability it helps stop or slow oil seepage, prevents fresh oil from dripping under the vehicle, and reduces oil dilution. The additive also assists piston rings and valve guides to restore better combustion sealing and reduce engine noise.\u003c\/p\u003e\n\n\u003ch3\u003eHow does LM 1005 stop or reduce oil leaks?\u003c\/h3\u003e\n\u003cp\u003eThe additive works by penetrating and softening oxidized or shrunken rubber and certain plastics used in engine seals. Restored seal geometry reduces gaps where oil can escape, which lowers visible seepage and puddling underneath a parked vehicle.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSoftens hardened seal compounds to restore flexibility and sealing contact\u003c\/li\u003e\n  \u003cli\u003eExpands slightly shrunken seals to close micro-gaps\u003c\/li\u003e\n  \u003cli\u003eCompatible with common automotive rubber and plastic engine seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it lower oil consumption and engine noise?\u003c\/h3\u003e\n\u003cp\u003eBy improving the sealing action of piston rings and valve stem seals, LM 1005 can reduce the amount of oil entering the combustion chamber and burning off.

Liqui Moly LM 1005 Oil Leak Stop is aimed at vehicle owners, maintenance technicians and fleet managers who want a non-invasive, in-engine option to reduce oil leaks, lower oil consumption and quiet seal-related engine noise. It’s suited to passenger cars, light commercial vehicles and older engines showing seepage from shaft seals, valve stems or increased oil usage due to degraded sealing components. For severe leaks or structural seal failure, mechanical repair or seal replacement remains the correct solution.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can LM 1005 fix big oil leaks from torn seals?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. It restores hardened seals and reduces seepage but cannot repair torn or mechanically damaged seals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How much of the 300 ml bottle should I add to my engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Follow Liqui Moly dosing instructions relative to your oil capacity; the bottle is sized for common treatment volumes.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Liqui Moly","offers":[{"title":"Default Title","offer_id":48084755644574,"sku":"B001CZSGTE","price":37.84,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/liqui-moly-lm-1005-front-packaging.jpg?v=1785861840","url":"https:\/\/northtrailauto.ca\/products\/liqui-moly-oil-leak-stop-engine-oil-additive-300-ml-restores-rubber-seals-reduces-oil-leaks","provider":"North Trail Auto","version":"1.0","type":"link"}
