LUCAS High Mileage Oil Stabilizer Pack of 2 — 100% Petroleum Formula, Reduces Friction & Quiet Gearboxes

LUCAS Oil 10118 High Mileage Oil Stabilizer (Pack of 2) is an all‑petroleum formula designed to reduce friction and wear in older or high‑mileage 4‑stroke engines, transmissions and primaries.

This concentrated oil stabilizer blends with existing motor oil to improve lubricity, quiet noisy gearboxes and help prevent the metal‑to‑metal contact that accelerates wear. Formulated from 100% petroleum base stocks and developed from racing‑grade knowledge, the product is compatible with air‑cooled and water‑cooled 4‑stroke engines and gearboxes that recommend SAE 20W‑50 oil. Supplied as a convenient pair, the twin-pack is ideal for routine maintenance or seasonal service intervals.

How does this stabilizer reduce engine friction and heat?

The formula deposits a thin, durable coating on metal surfaces that improves lubrication and reduces direct contact between moving parts. With better film strength the engine runs cooler and components experience less wear during operation. The stabilizer helps preserve oil viscosity under stress so the oil cushion remains effective at high temperatures.

• Creates a persistent lubricating film on metal surfaces
• Helps maintain oil viscosity under heavy use
• Reduces metal‑to‑metal contact and operating temperatures

Will it stop noisy gearboxes and prevent dry starts?

Yes — the coating action fills microscopic surface irregularities, which quiets gears and reduces start‑up wear when oil pressure is still building. That eliminates the harsh metal contact responsible for clatter and premature component fatigue. The result is smoother engagement and fewer cold‑start stresses on bearings and gears.

• Minimizes gearbox and primary chain noise
• Reduces wear during cold starts
• Improves clutch and transmission feel under load

How do I use LUCAS High Mileage Oil Stabilizer and when should I add it?

Mix the stabilizer with your engine oil according to the label directions — typically added during an oil change so it blends evenly. It’s suitable for periodic maintenance on high‑mileage machines or as a preventative measure whenever you change oil. Using the product as part of a scheduled service helps maintain protection between changes.

• Add during an oil change for best distribution
• Compatible with SAE 20W‑50 in 4‑stroke engines and gearboxes
• Sold in a two‑pack for multiple services or dual applications

Is this formula safe for seals, gaskets and older engines?

The stabilizer is an all‑petroleum product formulated to be seal‑safe for most older engines when used as directed. Its chemistry is designed to cling to metal surfaces without causing swelling or hardening of common elastomers. Still, consult the product instructions or manufacturer recommendations for specific seal or material concerns on very old or specialty engines.

• 100% petroleum base — designed to be seal‑compatible
• Formulated for high‑mileage engines and vintage applications
• Works with primaries, transmissions and 4‑stroke motor oil systems

Who is this for: LUCAS Oil 10118 High Mileage Oil Stabilizer (Pack of 2) is aimed at riders and vehicle owners with high‑mileage or aging 4‑stroke engines who want to reduce noise, extend component life and improve lubrication between oil changes. It’s well suited for motorcycle owners, small engine operators and anyone maintaining air‑cooled or water‑cooled engines and associated gearboxes that call for SAE 20W‑50 oil. Choose the twin pack if you perform regular maintenance on more than one machine or prefer to keep a spare on hand for future services.
