Oil Sampling Kit

Product Code: 
OAI
Teaser: 

A single sampling analysis is useful in providing information when critical failure conditions exist. However, trend analysis is a better tool for estimating the useful life or overall condition of your engine or equipment. Trend analysis samples are taken and analyzed at regularly scheduled intervals. Comparing the most recent analysis to previous reports on a given machine shows the development of trends. Monitoring these trends enables early detection of internal abnormalities. Tested values falling within acceptable limits may show a pattern of subtle variance, which could signal a developing problem.

AMSOILs AMS-OILER Oil Precharger

Product Code: 
AMK
Teaser: 

Over the years, AMSOIL research and development has responded to changes in the industry by developing products that keep AMSOIL on the cutting edge. The new AMS-Oiler is the most recent example in a long line of top-quality innovations from AMSOIL. Independent studies have concluded that engine wear during start-up is a major concern. Even though engine components remain dry for only a short period of time at ignition, when this circumstance is multiplied by the 400 to 600 dry starts a year by the average motorist, the potential for harmful metal-on-metal contact and significant wear is great.The AMS-Oiler is an oil pre-charger that puts an end to dry-engine starting.

AMSOIL Bypass Oil Filters

Product Code: 
BMK
Teaser: 

The AMSOIL By-Pass Oil Filter provides the best possible filtration protection against wear, oil degradation, rust and corrosion. Working in conjunction with the engine's full-flow oil filter, the AMSOIL By-Pass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately ten percent of the oil at any one time and traps the extremely small, wear-causing contaminants and water that full-flow filters can't remove. The AMSOIL By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
