Will using 100:1 mix ratios with AMSOIL Saber Professional or Saber Outboard Synthetic 2-Cycle Oil void warranties? Answer: Using AMSOIL Saber Professional or Saber Outboard at 100:1 mix ratios, where 50:1 is recommended by the manufacturer, will not void warranties.

Is it okay to break in new two-cycle equipment using AMSOIL synthetic motor oils? Yes. There are no problems using AMSOIL synthetic 2-stroke oils for break-in periods.
Does AMSOIL have a two-stroke oil recommended for power valves? AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil is recommended for power valve applications. It provides optimal detergency to keep power valves clean and superior anti-wear protection.
Two-Stroke Applications Two-stroke engines are generally less expensive to build compared to four-stroke engines, and they are lighter and can produce a higher power-to-weight ratio. For these reasons, two-stroke engines are ideal in applications such as chainsaws, weed trimmers, outboard motors, off-road motorcycles and racing applications. Two-stroke engines are also easier to start in cold temperatures, making them ideal for use in snowmobiles. Four-stroke engines, on the other hand, produce more torque at lower rpm, generally providing greater equipment durability than high-revving two-stroke engines, while also providing greater fuel efficiency and lower emissions. For these reasons, four-stroke engines are ideal in applications such as motorcycles, ATVs and personal watercraft.
Two-Stroke Lubrication Two-stroke engines collect some oil beneath the crankshaft; however, two-stroke engines employ a total-loss lubrication system that combines oil and fuel to provide both energy and engine lubrication. The oil and fuel are combined in the cylinder’s intake tract and lubricate critical components such as the crankshaft, connecting rods and cylinder walls.
Oil-injected two-stroke engines inject the oil directly into the engine, where it mixes with the fuel, while pre-mix two-stroke engines require a fuel-oil mixture that is combined before being installed in the fuel tank. In general, two-stroke engines are known to wear more quickly than four-stroke engines because they don’t have a dedicated lubricant source; however, high-quality two-stroke oil significantly reduces engine wear.
AMSOIL provides a full line of premium synthetic two- and four-stroke oils that provide outstanding protection and performance for recreational and work equipment.
