STA-BIL Full Synthetic 2-Cycle Oil 2.6 oz (12-Pack) — Premeasured 50:1/40:1 Low-Smoke Bottles, Built-In Fuel Stabilizer

STA-BIL Full Synthetic 2-Cycle Oil 2.6 oz (12-pack) is a ready-to-pour, low-smoke synthetic oil with built-in fuel stabilizer formulated for 2-cycle engines and designed to treat one gallon per bottle.

Keep small engines running cleaner and starting easier with a compact, premeasured oil that simplifies mixing and extends fuel life. Each 2.6 oz bottle in this 12-pack contains full synthetic 2-cycle oil blended with a stabilizer that helps preserve mixed fuel for long-term storage. The low-smoke formula reduces visible exhaust during startup, while the one-shot pour size eliminates measuring and mess—ideal for seasonal tools, recreational equipment, and service shops that need consistent, reliable mixtures.

How does this product make fueling two-stroke equipment easier?

Every 2.6 oz bottle is calibrated to treat one gallon of gasoline, so you can add oil directly to fuel without calculating ratios. Premeasured dosing minimizes over- or under-oiling, which helps maintain engine performance and simplifies refueling for users of different skill levels.

• One-shot pour size for a precise 50:1 or 40:1 mix depending on engine needs
• Premeasured bottles eliminate measuring tools and reduce spills
• Consistent synthetic formulation for repeatable mixing

Will this reduce smoke and visible exhaust during startup?

The formula is engineered to produce less visible smoke than conventional two-stroke oils, especially during cold starts or initial throttle. Lower smoke improves user comfort and keeps equipment looking cleaner without changing how you operate the engine.

• Low-smoke synthetic base for neater startup emissions
• Designed for modern carbureted and direct-injection two-cycle engines
• Helps keep spark plugs and exhaust ports cleaner over short-term use

How does the added fuel stabilizer benefit stored fuel and seasonal tools?

Each bottle contains a stabilizing additive that helps slow fuel degradation when oil is blended with gasoline. Treated fuel stays usable for extended periods—helpful for seasonal equipment stored over winter or backup tools kept for occasional use.

• Fuel stabilizer extends mixed-fuel freshness for up to one year
• Reduces varnish and gum formation in carburetors and fuel lines
• Useful for seasonal storage and emergency backup equipment

How long can I keep an opened bottle and is this oil compatible with my engine?

STA-BIL recommends using any STA-BIL branded product within two years after opening when properly stored, and marking the open date on the packaging helps track shelf life. The multi-mix synthetic formula is safe for most two-stroke engines that call for 50:1 or 40:1 mixtures, including handheld outdoor tools and recreational engines.

• Use within two years of opening for best performance (mark the open date)
• Multi-mix technology compatible with common 2-cycle ratios (50:1 and 40:1)
• Suitable for chainsaws, string trimmers, leaf blowers, snow blowers, and many marine or recreational two-stroke engines

Who is this for: This 12-pack of STA-BIL Full Synthetic 2-Cycle Oil is made for homeowners, landscapers, rental yards, and small engine technicians who want a clean-burning, premeasured oil that simplifies mixing and extends the life of stored fuel. Pick this pack if you value convenience, consistent oil-to-gas ratios, and the added benefit of a stabilizer for seasonal storage and occasional-use equipment.
