May 2026 Special: Chevron Delo 400 XLE 15W‑40

Texas heat and heavy-duty cycles are unforgiving on diesel engines. This May, Pak Petroleum Marketing is offering $1 off per gallon on Chevron Delo 400 XLE 15W‑40 synthetic blend. If you’re preparing equipment for long hours through summer, this is the time to stock up.

Why This Oil—and Why Now

Delo 400 XLE 15W‑40 is a synthetic‑blend heavy‑duty diesel engine oil designed for modern on‑ and off‑road equipment. In practical terms, that means stable viscosity under load, dependable film strength in high ambient temperatures, and protection that helps mixed fleets standardize on a single 15W‑40 across tractors, dozers, haul trucks, and generators.

As operating windows lengthen in Southeast Texas, engines spend more time at temperature and under load. A synthetic blend resists oxidation and shear so oil maintains pressure, film strength, and contaminant control between scheduled changes.

Who Benefits Most

This special is a fit for farmers and ranchers running tractors, combines, and stationary generators; construction crews fueling excavators, loaders, and dozers on tight timelines; and trucking or industrial operations that rack up long service hours in high ambient temperatures. If your equipment works outdoors in Southeast Texas, 15W‑40 remains the practical, proven viscosity—and Delo 400 XLE’s synthetic‑blend formulation adds a margin of protection when heat and load peak.

May Pricing

For the month of May, Delo 400 XLE 15W‑40 is available at the following prices:

• 3/1‑gallon case: $45.00 (was $48.00)

• 5‑gallon pail: $73.00 (was $78.00)

• 55‑gallon drum: $770.00 (was $825.00)

If you manage multiple machines or plan preventive maintenance cycles ahead of harvest or summer projects, the pail and drum formats typically offer the best per‑gallon economics and fewer changeovers.

Choosing the Right Format for Your Fleet

Smaller operations and service trucks often prefer the 3×1‑gallon case for clean top‑offs and light equipment service. Farms and job sites running several units benefit from 5‑gallon pails—easy to handle on site while minimizing open container time. High‑consumption fleets and shops standardize on 55‑gallon drums to reduce cost per gallon, keep inventory consistent, and simplify dispensing with dedicated pumps.

Whichever route you choose, store containers out of direct sun, keep bungs and lids clean, and use labeled pumps to prevent cross‑contamination. Monitoring hours and fuel use helps dial in drain intervals to your duty cycle and environment.

Order or Add to Your Next Delivery

We can deliver Delo 400 XLE 15W‑40 with your regular fuel or lubricants order, or stage it for pickup at our El Campo bulk plant (cash discount available).
