A public-school district based in San Diego County, California Vista Unified School District (VUSD), has converted its fleet of 53 school buses to run on Neste MY Renewable Diesel in order to cut back on the fleet’s maintenance costs.

Neste MY Renewable Diesel is a low-carbon fuel produced from 100 percent renewable and sustainable raw materials, primarily wastes and residues. This premium diesel cuts greenhouse gas emissions by up to 80 percent, and can reduce carbon monoxide by 24 percent and fine particulates by 33 percent, all while enhancing fleet performance. Unlike biodiesel, Neste MY Renewable Diesel is a direct replacement fuel that requires no blending and is compatible with all diesel engines.
VUSD is the 4th largest school district in San Diego County and is comprised of 32 schools with diverse educational programs that range from kindergarten schools through adult education facilities. VUSD serves more than 23,000 primary to high school students and 2,000 adult education students.
According to Bill Weisberg, director of transportation for VUSD, Neste MY Renewable Diesel offered improvements in several respects.
“When considering our students’ health and safety, the local air quality, and the reduction in preventative maintenance costs, this was clearly a win-win solution” Weisberg said. “We should see less residue in our fuel filters and in the Diesel Particulate Filters (DPF) filters. These filters constantly need attention when using standard CARB (petroleum) diesel. This will save our mechanics time and keep our buses on the road”.
Jeremy Baines, Vice President of Sales, Neste US, Inc., added that school-age children are some of the most susceptible to the effects of harmful emissions.
Biodiesel contain aromatics and impurities that can contaminate oil, foul fuel injectors and clog the DPF filters while renewable diesel contains nearly zero impurities and burns much cleaner. This can have an instant positive effect on exhaust aftertreatment systems – less soot produced can mean fewer DPF regenerations. It has a positive effect also on fuel system components as lack of impurities reduces deposit formation in critical fuel injector parts.
