Diversifying Fleet Fuels with Diesel, Renewable Diesel, CNG, and More
Chevron scientist Dave Slade advocates for a diverse fuel strategy, utilizing diesel, CNG, and renewables to manage market volatility and reduce carbon intensity.
Energy provider Chevron is encouraging fleet operators to adopt a multi-faceted approach to fuel procurement rather than switching to a single alternative source. In a report by FreightWaves, principal biofuels scientist Dave Slade noted that maintaining a diverse portfolio allows companies to navigate price fluctuations and seasonal availability. The company currently offers a variety of solutions, including traditional petroleum diesel, renewable natural gas, and various biodiesel blends.
Quality remains a primary concern for operators integrating renewable fuels into their supply chains. Slade emphasized that poorly processed biodiesels can result in equipment downtime due to filter blockages or failure in cold climates. To mitigate these risks, Chevron suggests that fleets verify fuel specifications against specific operating environments. The company also offers testing services to help clients determine the root causes of performance issues involving high-cost equipment.
The use of compressed natural gas is highlighted as a method for stabilizing fuel budgets. Historical data from the Department of Energy indicates that natural gas prices often experience less volatility than petroleum-based fuels. To lower the barrier for adoption, Chevron and Cummins have launched a demonstration program allowing eligible fleets to test heavy-duty natural gas engines for up to 18 days, providing an opportunity to evaluate performance before committing to a full conversion.
Technical collaborations are also focused on streamlining maintenance for mixed-fuel fleets. Lubricant technology, such as the Delo 600 ADF, has been approved for both diesel and natural gas engines, which may allow operators to consolidate their inventory. Slade argues that selecting the right energy source is essentially "choosing the right tool for the job," depending on specific goals, budgets, and hardware requirements.

Brent Back Above $100 as Houthis Hit Saudi Infrastructure
Crude oil prices, which dipped on Tuesday, reversed their direction, with Brent ticking above $100 again earlier today following reports of fresh Houthi attacks on Saudi energy infrastructure. At the time of writing, Brent crude was trading at $101.49 per barrel and West Texas Intermediate was changing hands for $90.14 per barrel, despite a statement from Saudi Arabia’s energy minister, Prince Abdulaziz bin Salman, who said Tuesday the kingdom’s oil flows via the Rast-West pipeline had rebounded to 5.8 million barrels daily.

Iranian Oil Starts Flowing to Tajikistan Despite U.S. Sanctions Risk
Tajikistan announced that it is now receiving oil and petroleum products from Iran, opening a potential new energy source for a country whose fuel supplies have long been dominated by Russia. The deliveries began in late August, Tajikistan's Energy and Water Resources Ministry told the Asia-Plus news agency, following talks between the two countries on expanding cooperation in the oil and gas sector. The ministry has not disclosed the volume of the shipments, their commercial terms, or how the oil and petroleum products were transported to Tajikistan.…
Iran’s Disappearing Oil Is Becoming Everyone’s Problem
Iranian oil is disappearing from the market just as its biggest buyer returns for more. China’s recovering crude demand is colliding with the loss of a supplier that sustained its independent refiners through the crisis, forcing them to compete for increasingly expensive alternatives. The consequences reach beyond China: every replacement barrel tightens supplies for other buyers, while Tehran faces a growing incentive to disrupt the Strait of Hormuz, which is now carrying an unexpectedly strong 13 million barrels a day (just 5 million below…
