AMSOIL Synthetic Motorcycle Oil - Rust Protection

Rust protection is particularly important in motorcycle applications.

Motorcycle engines are more susceptible to corrosion and rust than automobiles. Often used seasonally, then stored and unused for extended periods of time, condensation and moisture within the engine promote rust formation. 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 causes excessive wear on bearings, camshafts, lifters and gear surfaces.

Motor oil has little or no natural ability to prevent rust and 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 anti-wear additives for the metal surface, many motorcycle oils are formulated without rust inhibitors. AMSOIL Synthetic Motorcycle Oils are formulated with breakthrough technology not previously available, providing outstanding protection against rust without sacrificing wear protection.

The ASTM D-1748 Rust Test (humidity cabinet test) measures a lubricant's ability to protect against rust and corrosion. A standard metal reference coupon (metal plate) is immersed in the test oil before being placed in a humidity cabinet for 24 hours at 120 degrees F. Following the test period, the coupons are removed and inspected for rust. In order to pass the test, an oil may allow no more than three rust spots less than or equal to 1 mm in diameter. Oils allowing more than three rust spots, or one rust spot larger than 1 mm diameter, fail the test.

Two separate tests were performed. One test for SAE 40 and one for SAE 50 oils. Failing oils were divided into three categories: oils showing 1-10 spots, oils showing 11-20 spots and oils showing over 20 spots.

Both AMSOIL 10W-40 Synthetic Motorcycle Oil (MCF) and AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) showed no rust spots, placing them at the top of their respective test groups. Many competing motorcycle oils failed the test. AMSOIL Synthetic Motorcycle Oils provide unsurpassed rust protection, allowing motorcycles to perform better, last longer and require less maintenance.

AMSOIL Synthetic Motorcycle Oils

• Excellent for roller bearings and does not cause "skate" or "float" in V-Twin Engines
• Prevents foaming in high-RPM engines
• Eliminates the need for multiple lubricants
• Absolute shear stability maintains protective viscosity in high heat, high shear conditions
• Better performance and price than competitive motorcycle oils

AMSOIL Motorcycle Oil Filters

Only AMSOIL Ea Motorcycle Oil Filters feature full-synthetic nanofiber technology. It is the nanofibers that allow Ea Filters to provide greater efficiency than any other filter available. Ea Filters stop more particles, stop smaller particles and last longer than any other oil filter available for motorcycle applications.

AMSOIL Motorcycle Air Filters

AMSOIL Ea Motorcycle Air Filters with nanofiber technology hold 15 times more dust than wet gauze type filters. Nanofiber media removes 5 times more dust than traditional cellulose filters and 50 times more dust than than wet gauze type filters while allowing more efficient air flow compared to traditional filter medias.

FULL WARRANTY

AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.

Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.
