Lucas Oil Semi-Synthetic 2-Cycle Motor Oil 1 Gallon — Low‑Smoke, Up to 50:1 Premix

Lucas Oil 10115 is a semi-synthetic, low-smoke 2-cycle motor oil formulated for oil-injection systems and premix ratios up to 50:1 to promote cleaner combustion and reliable lubrication.

This 1‑gallon Lucas High Performance Semi‑Synthetic 2‑Cycle Oil blends mineral and synthetic base stocks with a low‑ash additive package and exclusive detergents to help reduce deposits and spark plug fouling in gasoline‑powered two‑stroke engines. It’s engineered for a broad range of handheld and recreational equipment — from chain saws and brush cutters to snowmobiles and leaf blowers — and meets ISO GD, JASO FD, and exceeds API TC specifications for two‑cycle service.

How does this oil improve combustion and reduce smoke?

The formula combines mineral and synthetic oils with a low‑ash additive system designed for more complete fuel burning and lower visible emissions. The mix of detergents and dispersants helps the oil combust more cleanly, contributing to reduced smoke output compared with conventional two‑stroke oils.

• Advanced "Smokeless" formulation for cleaner burning
• Low‑ash additive package to limit residue and deposits
• Detergents reduce carbon buildup on pistons and ports
• Suitable for low‑smoke oil requirements and colder temperatures

Will it protect engine parts and prevent fouling?

Lucas ashless detergent inhibitor package is included to minimize spark plug fouling, ring sticking, and combustion chamber deposits. The lubricants and inhibitors work together to keep exhaust ports, piston rings and crowns cleaner, extending trouble‑free operation between service intervals.

• Detergents and dispersants prevent carbon and varnish formation
• Lubricant additives reduce wear on cylinder walls and rings
• Minimizes spark plug fouling for more consistent ignition
• Less carbon on skirts and crowns for improved performance

What equipment and mixing ratios are recommended?

This oil is formulated for any oil injection system and for premix use up to a 50:1 ratio, covering most domestic and commercial two‑stroke machines. It’s designed to mix well with gasoline across a wide temperature range, so it’s suitable for both seasonal recreational equipment and everyday yard tools.

• Compatible with oil injection systems and manual premix
• Recommended premix ratios up to 50:1 (follow manufacturer guidance)
• Intended for air‑cooled gasoline two‑stroke engines
• Works with a variety of small engines: chainsaws, trimmers, blowers

How does this product meet industry standards and testing?

Lucas 10115 meets ISO GD and JASO FD performance classifications and exceeds the API TC requirement, reflecting its formulation for modern two‑stroke performance needs. Those standards indicate the oil has been evaluated for protection, cleanliness and smoke control in applicable test protocols.

• Meets ISO GD specification for two‑stroke oils
• JASO FD compliant for improved detergency and wear control
• Exceeds API TC baseline requirements
• Technical datasheets available from Lucas Oil for detailed specs

Who is this for: Lucas Oil 10115 is aimed at owners and operators of gasoline two‑stroke equipment who want a semi‑synthetic oil that balances cleaner combustion with strong deposit control. It’s a practical choice for professionals and homeowners who use chainsaws, hedge trimmers, string trimmers, blowers, snowmobiles and other two‑stroke machines and who need a single, versatile oil that performs in oil‑injection systems and premix setups. Always follow your engine manufacturer’s recommended oil-to-fuel ratio and service practices.
