AMSOIL SEMI-SYNTHETIC BAR AND CHAIN OIL

AMSOIL Semi-Synthetic Bar and Chain Oil delivers superior lubrication and wear protection for chainsaws, keeping bars, chains, and sprockets running cooler and lasting longer than conventional bar oils allow.

Chainsaw bars and chains operate under punishing conditions. The chain travels at high speed around the bar nose, generating significant friction and heat, while sawdust and debris constantly work their way into the contact surfaces. Conventional bar and chain oils often fling off at high chain speeds or thin out under heat, leaving metal-on-metal contact right where you need lubrication most. In cold weather, thick petroleum bar oils can struggle to flow through the oiler system at all, starving the bar of oil when you first start cutting.

TACKY FORMULA THAT STAYS WHERE IT BELONGS
The semi-synthetic formulation in AMSOIL Bar and Chain Oil clings to metal surfaces better than conventional bar oils. Its tackiness resists the centrifugal force that flings oil off the chain at operating speed, maintaining a consistent lubricating film across the bar rails and chain drive links. Less fling-off means more of the oil you put in the reservoir actually ends up doing its job, reducing consumption and keeping the saw cleaner around the clutch cover and housing area.

ANTI-WEAR ADDITIVES EXTEND BAR AND CHAIN LIFE
Friction between the chain's drive links and the bar rail groove is one of the primary wear points on any chainsaw. AMSOIL Semi-Synthetic Bar and Chain Oil contains anti-wear additives specifically formulated to reduce metal-to-metal contact at these high-load surfaces. The result is measurably longer bar and chain life, which adds up quickly if you're cutting firewood regularly, running a logging operation, or maintaining property with multiple saws in rotation.

REDUCED FRICTION, COOLER OPERATION
A well-lubricated chain doesn't just last longer, it cuts more efficiently. AMSOIL's semi-synthetic base oils provide a lower coefficient of friction than straight petroleum bar oils, which translates to less drag on the chain and lower operating temperatures at the bar nose. Lower friction also means less load on the engine, so the saw responds better under cut and wastes less power overcoming drag.

WORKS ACROSS A WIDE TEMPERATURE RANGE
One common frustration with conventional bar and chain oils is cold-weather performance. Many petroleum-based bar oils become too thick to flow through the oiler pickup when temperatures drop, leaving the bar dry during the first critical minutes of cutting. AMSOIL Semi-Synthetic Bar and Chain Oil maintains pumpability in cold conditions while still providing the tackiness and film strength needed in warm weather. This single-product versatility simplifies inventory whether you're running saws in a Canadian winter or a summer cleanup after a storm.

APPLICATIONS AND COMPATIBILITY
AMSOIL Semi-Synthetic Bar and Chain Oil is suitable for use in all chainsaws equipped with automatic or manual bar oiling systems, including Stihl, Husqvarna, Echo, Poulan, and other major brands. It is also well suited for use on bicycle chains where a tacky, protective lubricant is needed. Available in quart bottles, gallon jugs, 5-gallon pails, and 55-gallon drums to match usage volume from occasional homeowner cutting to professional timber and land-clearing operations.
