In 2017, Mansfield Energy Corporation contacted the Fuels Institute to discuss a pervasive problem popping up amongst their customers.Many fleets were experiencing diesel engine problems and downtime presumably as a result of fuel quality. Perplexed as to why this was happening and looking for answers, Mansfield reached out to the Fuels Institute and asked us to start an industry-wide initiative to investigate the issue and see if we could come up with any mitigation strategies.

Why Fuels Institute?

The Fuels Institute is known for bringing together transportation stakeholders to deliver objective, balanced research and analysis concerning fuels, vehicles and consumers. Because of our non-advocacy approach, we are a trusted source in the industry to tackle challenges facing the market in a collaborative way. When Mansfield approached us with this issue, we did what we do best – provided an unbiased forum in which all sectors of the market could come together to work toward a unified goal.
