Crude oil price [US$/barrel]<br />
• Diesel fuel prices rise and fall with crude oil prices – there‘s a high degree of correlation<br />
• Natural gas prices also correlate with crude oil prices (although less strongly)<br />
• As oil prices rise, the diesel-natural gas price gap widens, increasing HPDI‘s fuel cost savings<br />
