Truegard HD RR SAE 40, 20W40 is a superior, Low Ash Heavy Duty engine oil formulated to address the emerging fuel and emission standards coming to large, medium speed locomotive, marine vessels, and electric- powered generators. It is formulated with a blend of stable synthetic and premium mineral base stocks for long-life performance in 2 and 4 stroke Gen 6 (and all previous category) engines used in a wide range of marine trunk
piston, railroad, inland marine, mining and stationary engine applications. Patented non-chlorinated technology is  future proof for Gen 7 emission requirements.

Truegard HD RR SAE 40, 20W40 contains a Silver allow compatible thermally stable ashless additive package with an extremely shear- stable viscosity improver to protect under conditions of extreme heat in today's smaller engines which create more heat and pressure than previous generation. The ashless formulation is designed with no zinc nor chlorine to meet stringent government regulations. This also allows for use with alternate fuels such as distillates and asphaltenes. The protection afforded by this unique additive technology Truegard HD RR SAE 40, 20W40 to provide protection beyond that of a normal SAE 40 grade lubricant by controlling film thickness on critical engine parts such as Top Ring pistons.

The combination of premium synthetic and highly refined mineral base oils eliminate wax formation allowing the engine to reduce emissions and oil consumption. These heavy weight base stocks also drastically reduce volatility in high-temperature areas of the engine leaving thicker layers of the protective films which reduce wear and improve fuel economy. Reduced volatility also reduces soot and other deposits that collect to retard and place stress on internal engine components.

Frequently asked questions

Find answers to common questions about our products and services

  • This oil is formulated for large and medium-speed 2-stroke and 4-stroke engines used across railroad (locomotive), marine trunk piston, inland marine, mining, and stationary power generation (including electric-powered generators) applications. It meets requirements for Gen 6 and all previous engine categories in those sectors.

  • The 20W rating means the oil flows adequately in cooler conditions like a lighter 20-weight oil, while the 40 rating ensures the correct film thickness at full operating temperature. The product description notes that the thermally stable additive package and shear-stable viscosity improver allow it to deliver protection beyond that of a standard SAE 40, particularly by maintaining film thickness on critical parts like top ring pistons under extreme heat and pressure.

  • The ashless, zinc-free, and chlorine-free formulation is designed to meet stringent government emission regulations for locomotive and marine environments. This formulation is also what makes the oil compatible with silver alloy engine components common in these applications, and it enables safe use with alternate fuels such as distillates and asphaltenes without chemical incompatibility.

  • Yes, the additive package is specifically described as silver alloy compatible, which is important in medium-speed marine trunk piston and locomotive engines where silver-plated bearings and components are commonly used. This compatibility is a direct result of the ashless, non-chlorinated formulation.

  • Yes, the ashless formulation with no zinc or chlorine allows for use with alternate fuels such as distillates and asphaltenes, making it suitable for operations where fuel composition may vary or where non-standard fuels are used in stationary or marine engines.

  • According to the product data, the patented non-chlorinated technology is described as 'future proof' for Gen 7 emission requirements, meaning operators investing in this oil now should not need to switch formulations when next-generation engine emission standards take effect.
