Can Valero's Heavy Crude Advantage Support Stronger Refining Margins?
Read MoreHide Full Article
Key Takeaways
Valero expects heavy sour crude discounts to remain elevated, supporting favorable refining margins.
VLO processed 514 MBPD of heavy sour crude in second-quarter 2026, highlighting its feedstock flexibility.
Valero anticipates record Venezuelan heavy-crude runs, while Canadian supplies offer an additional option.
Valero Energy Corporation (VLO - Free Report) is well positioned to benefit from a favorable crude-sourcing backdrop, with management expecting crude-quality discounts, particularly for heavy sour grades, to remain stronger than historical levels. The outlook supports refining economics because discounted feedstocks can widen the spread between crude input costs and refined-product values. The U.S. Gulf Coast remains a key crude-sourcing hub for Valero, offering access to oil from domestic producers, Canada and Venezuela.
The sourcing advantage fits well with VLO’s operating footprint. The company runs 14 refineries across the United States, Canada and the U.K., with roughly 3 million barrels per day of throughput capacity, giving it meaningful flexibility across crude grades. In the second quarter, Valero processed 514 thousand barrels per day (MBPD) of heavy sour crude, highlighting its ability to handle these barrels at scale. Management expects Venezuelan heavy-crude runs to exceed historical highs in the coming months, while Canadian heavy remains another important feedstock option.
The sourcing flexibility gives Valero greater room to shift toward the most attractive barrels as regional pricing changes. Management identified lower delivered crude costs as a key tailwind entering the third quarter and noted that several crude grades were being purchased at discounts to benchmarks. VLO is focusing on shorter-cycle projects to improve crude and product optionality across its refining system. As heavier crude availability improves and crude-quality discounts remain supportive, Valero’s feedstock flexibility strengthens its ability to capture favorable refining economics.
Heavy Crude Flexibility Supports PSX & MPC Refining Margins
Heavy-crude processing capability remains an important advantage for complex U.S. refiners such as Phillips 66 (PSX - Free Report) and Marathon Petroleum Corporation (MPC - Free Report) , as discounted sour barrels improve feedstock economics and support stronger margin capture.
Phillips 66 is well-positioned to benefit from wider heavy-crude discounts through a refining system designed to process medium and heavy grades while retaining flexibility to shift toward lighter crude. The refiner has highlighted its peer-leading bottoms upgrading capacity, which enhances its ability to capitalize on discounted feedstocks without sacrificing crude-slate flexibility. The earnings leverage is meaningful, with PSX estimating that every $1-per-barrel widening in the West Texas Intermediate-Western Canadian Select (“WCS”) differential adds about $140 million to annual EBITDA. This flexibility, along with access to Canadian crude and strong Central Corridor positioning, strengthens Phillips 66’s refining economics when heavy-crude differentials widen.
Marathon Petroleum has substantial exposure to sour-crude economics across its refining network. The refiner expects roughly half of the crude processed at its refineries in 2026 to be sour, with its sour basket including WCS, Maya, ASCI and Alaska North Slope grades. Marathon Petroleum estimates that a $1-per-barrel change in sour crude differentials affects annual Refining & Marketing adjusted EBITDA by about $520 million, highlighting the importance of feedstock discounts to profitability. MPC benefits from advantaged Canadian crude logistics at several Mid-Continent refineries, while its broader system provides flexibility to optimize crude sourcing and product placement across regions.
VLO’s Price Performance, Valuation & Estimates
Valero shares have risen 183.5% over the past year compared with the industry’s 149.1% growth.
