Fleet operators today face significant complexity as they balance emissions targets, operational efficiency, and cost management. Fuel diversity is increasing as fleets incorporate lower carbon intensity fuels such as compressed natural gas (CNG), renewable natural gas (RNG), biodiesel, and renewable diesel along with petroleum diesel. Yet this fuel diversification can create new challenges: maintaining compatibility across mixed fleets, managing multiple supplier relationships, and ensuring that lubricants work optimally with evolving fuel technologies.
Chevron addresses these challenges through integrated expertise in both advanced fuels and lubricants. This dual capability allows the company to deliver solutions that work together to help maximize performance, efficiency, and lower carbon intensity across diverse fleet operations.
Advanced fuel solutions driving measurable results
Chevron’s broad fuel portfolio demonstrates the company’s focus on both innovation and practical performance. Each fuel type delivers specific advantages that address different needs while maintaining the reliability fleet operators require.
Chevron is widely known for its production and supply of petroleum diesel, which is an essential fuel for most fuel portfolios. From here, fleets have options to incorporate a range of lower carbon intensity fuel choices, depending on the emission reduction targets they may have set, available engine types, and their budget.
When considering lower carbon intensity fuel options from Chevron, their renewable diesel represents years of innovation in lower carbon intensity fuel technology. Produced from renewable feedstocks such as used cooking oil, animal fats, and plant oils, it can deliver an average of 50% lifecycle carbon intensity reduction compared to petroleum diesel. The fuel integrates with existing infrastructure, normally requiring no engine modifications or special handling procedures.
Chevron’s biodiesel blends may offer carbon emission reduction benefits with existing infrastructure compatibility. B20 blends (i.e., blending 20% biodiesel and 80% petroleum diesel) can provide lifecycle carbon reductions while maintaining cold weather operability and fuel system compatibility. Biodiesel has natural lubricity and meets fuels specifications without the need for additives.
For fleets looking to reduce their costs along with emissions, Chevron’s CNG and RNG solutions can deliver compelling advantages. CNG typically costs around 20% less than diesel on an energy-equivalent basis while reducing nitrogen oxide emissions by 90% relative to 2010 standards. According to an American Gas Foundation study, RNG produced from organic waste sources such as manure from dairy farms can reduce carbon intensity by more than 100% on a lifecycle basis, making it one of the lowest carbon intensity transportation fuels available today. Chevron’s network of CNG stations offer refueling times comparable to traditional diesel.
Lubricant innovation enabling fuel flexibility
Managing multiple fuel types can bring complexity to lubricant use. Different engine technologies require different oils, creating inventory challenges and increased risk for misapplication. Chevron’s Delo 600 ADF eliminates this complexity while optimizing performance across all fuel platforms. In essence, Delo 600 ADF serves as a one-stop-shop for all engine technologies, helping to cut down on confusion, cost, and inventory in the maintenance shop.
Introduced in 2019, Delo 600 ADF incorporates Chevron’s patented OMNIMAX™ technology formulated with just 0.4% ash content, a 60% reduction compared to conventional CK-4 oils. This ultra-low ash formulation serves both traditional diesel and compressed natural gas engines with a single product, eliminating inventory complexity and application risks.
The certification process validated this capability through rigorous testing. “This certification followed an exhaustive two-year field testing process in Cummins engines, culminating in a complete engine teardown and inspection by Cummins engineers,” explained Shawn Whitacre, Principal Engineer at Chevron. The result was Cummins CES 20092 approval, the industry standard for mobile natural gas engine oils in North America.
Additionally, Delo 600 ADF is ahead of the curve for PC-12, the next generation heavy-duty engine oil specification currently in development. This forward-thinking certification means fleet operators investing in Delo 600 ADF today are positioning themselves for future regulatory requirements without likely needing another oil change. While competitors scramble to reformulate their products when PC-12 becomes mandatory, Delo 600 ADF users will already be compliant, avoiding the disruption and costs associated with specification transitions.
The synergy of integrated solutions
The true advantage of Chevron’s approach emerges when fuels and lubricants work together as an integrated system. This synergy delivers performance and efficiency benefits for operations.
Renewable diesel generates lower particulate matter emissions than petroleum diesel. When combined with Delo 600 ADF’s ultra-low ash formulation, it significantly extends diesel particulate filter performance (DPF). Research shows that approximately 90% of the incombustible ash that clogs diesel particulate filters comes from metallic additives in engine oil. By reducing ash content by 60%, Delo 600 ADF can dramatically extend DPF service life. Fleet operators have reported extending DPF service life by up to four times, reaching up to 24,000 hours before requiring maintenance.
This extended DPF life directly impacts fuel economy through multiple mechanisms. Ash buildup increases system backpressure and demands more frequent regeneration events, both of which consume fuel. Chevron’s research demonstrates that vehicles using conventional oils experience steadily worsening fuel economy as ash accumulates, while those using ultra-low ash oil maintain better fuel efficiency over time. The data indicates potential fuel economy retention benefits of up to 3%.
For operations using Chevron’s renewable diesel, the fuel’s superior combustion characteristics produce less soot and fewer combustion byproducts than petroleum diesel. This combustion profile complements Delo 600 ADF’s low-ash formulation, supporting extended maintenance intervals and sustained engine performance.
For CNG operations, the benefits are equally compelling. Natural gas combustion produces minimal soot, but using oils formulated for diesel applications have historically been incompatible. Delo 600 ADF’s dual certification eliminates this risk while its ultra low-ash formulation complements CNG’s lower nitrogen oxide emissions. Operations using both products can also see lower carbon intensity from CNG and extended oil drain intervals from the lubricant’s advanced formulation.
Oil drain intervals see improved extension with this integrated approach. Fleet operators using Chevron fuels and Delo 600 ADF consistently report safe extensions from intervals for both short- and long-haul operations. These extended intervals can translate to reduced downtime, lower maintenance costs, and decreased environmental impact from waste oil disposal.
Real-world transformation across fuel platforms
The benefits of Chevron’s products are proven when real customers find value. Take Santoro Oil for example, a family-owned heating and cooling service provider in Rhode Island and southern Massachusetts, operates in challenging stop-and-go conditions with significant idle time. Since switching to Delo 600 ADF, the company has extended oil drain intervals from 350 hours to 1,050 hours while increasing DPF service life by four times, reaching up to 24,000 hours before requiring maintenance. With industry average DPF cleaning costs at $500 and replacement costs around $1,200, these extensions represent substantial financial savings.
For mixed fleet operations, the integrated approach proves transformational. Ecology Auto Parts operates 625 vehicles running on both traditional diesel and CNG.
“Using one oil means we don’t need multiple tanks,” explained Greg Evans, the company’s fleet director. “There’s no risk of misapplication, and it reduces our inventory and labor expenses.”
The operational simplicity enables Ecology Auto Parts to evaluate additional fuel options, including renewable diesel and biodiesel blends, without concern for lubricant compatibility or inventory complexity.
Customers have also found operational success by incorporating CNG into their fuel portfolio. Gazelle Transportation, a fleet that specializes in transporting crude oil and petroleum products in California, added seven CNG trucks to their fleet in 2019, working with Chevron as their fuel provider. Within 90 days, drivers were comfortable in the new vehicles, noting very minor differences in performance compared to traditional diesel.
Fast forward to 2025, and Gazelle now has 23 CNG trucks — demonstrating their confidence in CNG technology.
“The benefit of running CNG trucks for us has been lowering our number two operating expense — diesel fuel,” shared Ron Lallo, CEO of Gazelle Transportation. “It’s number two next to labor. We’ve essentially been able to cut our fuel costs in half.”
Single-source advantage
Working with Chevron as a single provider for all fuel types and lubricants enables operators to streamline their supply chain while ensuring compatibility across operations. This single-source approach eliminates the complexity of managing multiple suppliers with different specifications, quality standards, and delivery schedules while providing access to technical expertise across the entire range of fuel and lubricant products.
The technical support advantage proves particularly valuable during fuel transitions. Chevron’s integrated expertise means fleet operators receive guidance on optimizing both fuel selection and lubricant performance for their specific operational profiles. This holistic approach identifies opportunities for efficiency improvements that might be missed when working with separate fuel and lubricant suppliers.
Supply chain reliability benefits from consolidated sourcing as well. Single delivery schedules, unified quality standards, and integrated inventory management reduce administrative burden while ensuring consistent product availability. For fleet operators managing multiple locations, this simplification translates to significant cost savings and operational efficiency.
Chevron is your source for the path forward
As the transportation industry evolves under increasing pressure to improve efficiency and reduce emission intensity, fuel diversification has become increasingly important for competitive operations. Yet diversification without integration creates new complexities that can erode the intended benefits.
Chevron’s approach helps solve this challenge by delivering both advanced fuel technologies and compatible lubricant solutions through a single provider with deep expertise in both domains. The real-world experiences across diverse applications validate the transformative impact of this integrated strategy. From extending drain intervals and reducing DPF maintenance to improving fuel economy and simplifying inventory management, the benefits are substantial and measurable.
As fleet composition continues diversifying with alternative fuel adoption, Chevron’s integrated approach offers operators the flexibility to optimize their complete energy strategy while maintaining the operational simplicity that drives profitability in an increasingly competitive landscape.
