With its extended drain intervals, AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil reduces maintenance costs, downtime and the cost of waste oil disposal.

Designed for high horsepower racing engines, typically supercharged and alcohol-burning or nitro-fueled, and requiring a high viscosity oil to resist the thinning effects of fuel dilution. Formulated specifically for wear protection and friction reduction in the extreme service conditions of racing. It has been proven on-track to bring down high engine oil sump temperatures by 20 degrees F, which speaks directly to its ability to reduce friction, promote power and inhibit wear.

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.
