Liqui Moly Motor Oil Saver engine additive — 2 x 300 ml pack, restores seals & reduces oil consumption

Liqui Moly Motor Oil Saver is an engine additive that helps soften and restore hardened rubber and plastic seals in the oil circuit, reducing oil consumption and external leaks.

This concentrated formula from Liqui Moly is designed for gasoline and diesel engines to rejuvenate valve stem seals and other oil-carrying elastomers without needing disassembly. By conditioning seals and gaskets, it helps curb blue exhaust smoke, limits oil loss, and can reduce the frequency of minor repairs. It is supplied here as a convenient two-pack of 300 ml bottles, suitable for periodic maintenance or multiple treatment intervals.

How does this product reduce oil consumption?

Motor Oil Saver works by penetrating and conditioning aged rubber and plastic components in the engine’s oil circuit, improving their elasticity and sealing function. As seals regain pliancy, they prevent oil from bypassing into combustion chambers or leaking externally.

• Restores flexibility to valve stem seals and gaskets
• Reduces internal oil blow-by that causes blue smoke
• Helps minimize external weeping and drips

When and how should I use the 300 ml bottle?

For most passenger cars, one 300 ml bottle is mixed into the crankcase oil during an oil change or with the engine at operating temperature per Liqui Moly instructions. The two-pack lets you treat two vehicles or apply a follow-up treatment after mileage accumulates.

• Add during oil change or pour into warm oil for best dispersion
• One 300 ml dose typically treats a single full-size engine oil capacity
• Repeat treatments can be scheduled according to oil consumption and service needs

Will it affect engine oil properties or warranties?

Motor Oil Saver is formulated to be compatible with common engine oils and intended as a maintenance additive—not a performance oil substitute. Always check vehicle manufacturer recommendations and warranty terms before use; compatibility with the oil type (mineral, semi-synthetic, synthetic) should be verified.

• Designed to be mixed with existing engine oils
• Does not replace regular oil specifications or scheduled service
• Consult manufacturer guidance for warranty-related questions

How quickly will I see results and what are realistic outcomes?

Some users notice reduced smoke and lower oil consumption within a short driving period after treatment; full benefits can appear over several hundred kilometers as the additive conditions seals. Results vary with seal age, engine wear, and the severity of existing leaks.

• Initial improvements often visible after short use
• Complete effect may require driving several hundred kilometers
• Best for engines with aging seals rather than severe mechanical damage

Who is this for: Liqui Moly Motor Oil Saver 300 ml — 2 Pack suits vehicle owners and maintenance professionals looking to extend the service life of engine seals, reduce oil consumption between repairs, and limit visible exhaust smoke. It is intended for owners of gasoline and diesel cars who prefer a preventative or restorative additive as part of regular maintenance, or workshops that want a handy two-pack for multiple customer jobs. This product is not a substitute for required mechanical repairs where seals are physically damaged or where internal wear is severe.
