Selecting Heavy-Duty Engine Oil for Improved Fuel Efficiency and Performance

Whitepaper

Noria Corporation

The EPA/NHTSA’s jointly issued GHG (Greenhouse Gas – CO2) Phase 2 Requirements in 2021 and these requirements will tighten in 2024 and 2027. These requirements reduce GHG by increasing fuel economy, thus burning less fuel, for medium and heavy-duty trucks. The Phase 2 requirements also tighten NOX (Nitrogen Oxides) limits, which should help reduce smog. The Phase 2 requirements will not only improve the energy efficiency of the nation’s fleets but will also reduce petroleum consumption in the United States, lower greenhouse gas emissions and improve air quality.

One way engine manufacturers are striving to meet the Phase 2 fuel economy requirements is through the strategic selection of engine oil viscosity grades. The harder your engine works, the more fuel it burns to compensate for the energy lost through heat and friction. Furthermore, as an engine works harder, it’s increasingly susceptible to wear and overheating, which can affect engine performance over time. The right oil will reduce friction in the engine by optimally lubricating contact points so components don’t require as much energy to run smoothly. The result is improved fuel economy and a protected engine, which can save a company major costs in the long haul.
