Cleaner Diesel Fuel

The EPA also established emissions standards for diesel engine highway vehicles for model year 2007 and later. These engines are designed to operate only with ULSD fuel. Using our Green Diesel fuel and advanced exhaust emission control systems can reduce vehicle particulate emissions by up to 90% and emissions of nitrogen compounds (NOx) by 25% to 50%. ULSD fuel helps reduce emissions in older engines as well.
Our Top Tier Diesel Fuels meet the high-quality fuel performance standards developed by some of the leading automotive and heavy-duty equipment manufacturers. TOP TIER™ provides benefits to consumers, retailers, and vehicle manufacturers by improving fuel quality to meet the increasing demands of evolving engine technology.

Green Diesel

Renewable diesel is a transportation fuel produced from non-petroleum renewable sources – specifically, vegetable oils and animal fats. The chemical and structural properties of renewable diesel are similar to petroleum-derived (conventional) diesel, and renewable diesel meets the federal registration requirements for fuels and fuel additives and the ASTM D975-21 Standard Specification for Diesel Fuel. Therefore, renewable diesel can be used as a direct substitute for conventional diesel (up to 100% or R100). Blends of renewable diesel and conventional diesel are labelled with an R followed by the percentage (by volume) of the renewable diesel content.
