New AMSOIL Synthetic Motorcycle Oils Provide Superior Transmission and Rust Protection

Rust Protection - Expected or Neglected?

Motorcycle engines are more susceptible to corrosion and rust than automobiles. Often stored and unused for extended periods of time, motorcycle engines are commonly exposed to humidity and damp environments that promote rust. In addition, the combustion process and short trip driving create condensation and acids that further promote corrosion and rust.

Because it is as abrasive as dirt, rust causes a myriad of problems, including scratching and pitting on cylinders, pistons and bearing surfaces, leading to blow-by, lower compression and reduced power and performance. When rust forms on Harley-Davidson needle bearings, bearing failure results. Rust also cause excessive wear on bearings, camshafts, lifters and gear surfaces.

Motor oil cannot provide rust protection on its own. It must be formulated with special rust inhibitors. However, because rust inhibitors typically sacrifice wear protection by competing with antiwear additives for the metal surface, most motorcycle oils are formulated without rust inhibitors. New AMSOIL Synthetic Motorcycle Oils are formulated with break-through technology not previously available, providing outstanding protection against rust without sacrificing wear protection.

The ASTM D-1748 Rust Test measures a lubricant's ability to protect against rust and corrosion. A standard metal reference coupon is immersed in the test oil before being placed in a humidity cabinet for 24 hours at 120 degrees F. As evidenced in the photos, the reference coupons treated with AMSOIL Synthetic Motorcycle Oils showed no signs of rust and corrosion, while the competitors failed the test.

Benefits of the two new oils include:

· Improved Transmission Protection
· Excellent Wet Clutch Performance
· Excellent Corrosion Protection
· Outstanding Heat Resistance
· Robust Additive Levels
· Excellent Value for Cost Effective Performance
