Many people have the perception that since synthetics are more slippery than petroleum oils (which simple don't reduce friction as well), that wet clutch packs in either their automotive automatic transmission or motorcycle transmission will slip when using super slippery synthetics. 

Look at it this way. Wet sandpaper removes paint as well as dry sandpaper does. The slipperiness of the water does not impede the sandpaper's ability to function. The same applies to the slipperiness of synthetic lubes in wet clutches.

It is simply not an issue. However, just as rinsing the sandpaper keeps it cleaner longer so it functions better longer, so the synthetic lubricant keeps wet clutch plates cleaner longer so they function better.

And, since synthetics are superior cooling agents to conventional petroleum lubes, using synthetics will help wet clutches last longer, too.

Petroleum oils have low resistance to heat and allow varnish and glaze to form on clutch plates,  which eventually leads to slippage and increased heat generation and eventually failure of the clutch pack.

Also, AMSOIL motorcycle oils are specifically formulated without any friction modifiers for compatibility with wet clutch packs. AMSOIL ATF lubricants are also designed with specific coefficient of friction values to meet the requirements of each and every specification that it not only meets, but far exceeds.

Now you know the facts. The next time your buddy mentions this as a potential issue, you can explain to him exactly why it is simply not an issue.

Since 1972, AMSOIL  Synthetics have proven to be the BEST.   AMSOIL also engineers and manufactures Super Duty Oil filters which have a 12,500 mile service life as well as specialized filtration systems for commercial and fleet  applications in cars and light, medium and heavy trucks which can filter particles down to less than one micron ( a standard full flow oil filter can only filter to 20-25 microns, and at a reduced efficiency) making oil changes virtually unnecessary and virtually eliminating engine wear.  These filters have been proven by millions of miles of over-the road trucks, construction equipment and fleet service.  

• AMSOIL saves you time and money.
• The only 25,000 mile/one- year and 35,000/one- year motor oil in the world.
• Exceeds the most stringent performance specifications of all major U.S. and foreign automotive and truck manufacturers.
• Provides up to two-times the wear protection of other motor oils.
• Increases the life of your vehicle.
• Improves performance, fuel economy and efficiency.
• Diesel oil and filtration products designed to deliver 1,000,000 miles for over-the-road trucks before engine overhaul. 
• Used by many national racing teams, fleets, police departments, construction firms and trucking companies.
