Nanofiber is a phrase generally referring to a fiber with a diameter less than one micron. Cellulose fibers, on the other hand, are larger than nanofibers and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, resulting in higher restriction and less capacity.

AMSOIL Ea Air filters incorporate a specially constructed cellulose media with exclusive synthetic nanofibers applied to the surface. Dust and submicron particles are trapped on the nanofiber surface, preventing them from lodging in the filter media depth.

Here’s how it works: Imagine two filtration media, a chain link fence and a mosquito net. Each is required to stop contaminants, in this case tennis balls. A tennis ball will fit quite nicely into an opening of a chain link fence, but will obstruct the hole almost 100 percent. Now, imagine a tennis ball covering a mosquito net. The tennis ball, at the point of contact with the netting, will obstruct much less filter area than the chain link fence example. In fact, air will flow around the tennis ball all the way to the point of contact. It will take many more particles to obstruct the netting surface area than the chain link fence.

The new nanofiber technology used in AMSOIL Ea filters surpasses all other technology in efficiency, capacity and service life. With AMSOIL Ea Air Filters, dust and submicron particles remain on the surface and are trapped in the nanofibers, preventing particles from lodging in the filter media depth. This produces higher efficiency and higher capacity which extends engine and filter life and reduces engine wear.

Amsoil offers Synthetic Motor Oils specifically formulated for motorcycle use. AMSOIL Synthetic Motorcycle Oils have been reformulated with new high performance additive technology that provides even greater multi-functional benefits for the special requirements of motorcycle applications. These independent and exclusive new AMSOIL formulations provide second-to-none viscosity protection for hot- running American and foreign motorcycle engines, transmissions and primary chaincases.

One of the greatest advantages of Amsoil's motorcycle oil is their superior rust-resistance. Anti- rust additives are difficult to get right, but Amsoil's engineers have figured out how to get great rust resistance without compromising the performance of the oil. This is very important for motorcycles that sit for a few days or weeks between uses. Rust in your motor is BAD!

From AMSOIL Action News:
The function of a vehicle’s differential is to transmit engine power to the wheels, while allowing them to rotate at different speeds. Differential design has evolved greatly since its conception. The first differential is thought to have been an early clockwork mechanism of Greek origin, and it can be traced back to around 87 B.C. The lubrication used for these gears is unknown, but because a lubricant of any kind may have changed the clock’s timing, it is speculated that no lubricant was used. Most all branches of engineering owe something to clock making. For example, the thermostat in an oven, the chain drive of a dredger and the differential gear in the axle of a car were all first invented for clockwork. Wooden cylindrical peg type gears lubricated with animal fat were used around 1200 A.D. for ship anchor hoists and catapult pre-tensioning. In 1827 Onesime Pecqueur of France installed the first differential gearing into a steam-powered machine. Pecqueur also invented and patented the first limited slip type axle. In 1870 James Starley, known as the father of the British bicycle industry, invented a tricycle with a differential gear, and the principle was used as the basis for the automotive differential. Automotive differentials incorporated worm drive gear sets lubricated with heavy petroleum oil until Packard introduced the modern hypoid differential in 1925.

The worm drive differentials used in early automobiles were unreliable and noisy. The introduction of hypoid gears solved the noise problem, but their sliding action increased wear. In order to extend gear life, lead-type extreme pressure (EP) additives were developed and added to gear lubes in 1930. However, because lead was determined to cause health problems, the lead-type EP additives were replaced by sulfur phosphorus EP additives in the 1950’s. The sulfur phosphorus additives provided improved benefits and are still in use today.

Automotive and truck differentials were not always exposed to the extreme conditions seen today, and higher quality gear lubricants have become increasingly important as vehicles have changed and improved.

Although differential designs and sizes have not changed much over the last 40 years, the operating conditions are very different. Differential operating conditions have become increasingly severe through the years due to the following: 1) Less lubricant used 2) Up to 93 percent more horsepower 3) Towing limits increased from 7,500 to 18,000 lbs. 4) Air flow for cooling decreased in favor of increased aerodynamics 5) Smog systems require hotter running engines, generating increased air temperatures around the differential 6) Increased differential temperatures up to 300°F 7) Increased interior room sacrifices air space for cooling around the differential 8) Exhaust pipes and mufflers pushed closer to the differential, increasing heat.

AMSOIL Synthetic Gear Lubes are specifically formulated to address modern differential operating conditions, providing extended drain intervals, long differential gear and bearing life and peace of mind. New differentials go through a break-in period and should have the break-in gear lube changed after the first 5,000 miles to assure differential integrity over the life of the vehicle. AMSOIL Synthetic Gear Lubes provide superior protection and performance for differentials following the break-in period, saving motorists money through extended drain intervals, while also costing less per quart compared to many competing OEM gear lubes.
