Here's How PSX's Flexible Crude Slate Supports Its Refining Economics
Read MoreHide Full Article
Key Takeaways
PSX can process light, medium and heavy crude grades to capture feedstock discounts across markets.
PSX benefits from Canadian and Venezuelan crude supplies and optimized sourcing to boost refining margins.
Every $1 widening in the WTI/WCS differential adds an estimated $140 million to Phillips 66's annual EBITDA.
Phillips 66’s (PSX - Free Report) refining system benefits from a flexible crude slate that enables the company to process a wide range of light, medium and heavy crude grades. Its refineries hold a peer-leading position in bottoms upgrading capacity, supporting greater use of medium and heavy barrels while retaining the flexibility to shift toward lighter crude when economics favor that mix. This flexibility gives PSX more options to capture favorable feedstock discounts across changing crude markets. The company sources low-cost hydrocarbons from the United States, Canada and Latin America and converts them into higher-value refined products.
PSX’s commercial network strengthens the advantage by optimizing crude sourcing across its refining system. Management highlighted the company's ability to replace costlier international crude with cheaper domestic grades at its U.S. refineries while marketing higher-priced barrels elsewhere, thereby strengthening refining margins. Phillips 66 has expanded its exposure to advantaged Canadian and Venezuelan crude supplies, providing additional opportunities when heavy crude differentials widen.
Please note that every $1-per-barrel widening in the West Texas Intermediate (“WTI”)/Western Canadian Select (“WCS”) differential adds an estimated $140 million to PSX’s annual EBITDA, highlighting the earnings leverage from discounted heavy crude. This feedstock flexibility complements improving refinery utilization, clean product yields and cost discipline, with crude utilization reaching 96% and realized refining margin at $24.08 per barrel in the second quarter of 2026. Therefore, Phillips 66’s ability to switch among crude grades, source advantaged barrels and optimize flows across its integrated network strengthens its refining margins and supports more resilient downstream earnings.
Flexible Feedstocks Aid Refining Margin for MPC & VLO
Among Phillips 66’s refining peers, Marathon Petroleum Corporation (MPC - Free Report) benefits from a highly flexible refining network that provides access to abundant, advantaged North American crude. MPC highlights the flexibility of its refining system as a key margin driver, while the Garyville Feedstock Optimization project is designed to improve the feedstock slate and raise crude throughput by 30,000 barrels per day by year-end 2027. For MPC, this combination of complex refining assets and feedstock optimization strengthens its ability to capture favorable crude differentials and lift refining economics.
Valero Energy Corporation (VLO - Free Report) operates a large refining network with 14 refineries and nearly 3 million barrels per day of throughput capacity, giving it significant flexibility in feedstock selection and product optimization. VLO processes a broad range of feedstocks, including heavy sour crude at its Port Arthur refinery, giving the company exposure to discounted crude grades when market spreads are favorable. This flexibility, combined with extensive pipelines, storage and dock infrastructure, helps VLO direct advantaged feedstocks across its system and support stronger margin capture.
Together, MPC and VLO demonstrate that feedstock flexibility and access to discounted crude grades remain key competitive advantages for complex U.S. refiners.
