- The full corridor list: all 12 Costco diesel stations within 12 miles of I-5 — 3 in California, 2 in Oregon, 7 in Washington — listed south to north with addresses and phone numbers.
- Next-diesel mileage for every station, so you know exactly how far each tank has to stretch.
- Tap-friendly links: each station links to its Costco warehouse page and a Google Maps navigation pin when you read on a phone.
- Detour backups: 7 more diesel Costcos 12–25 miles off the freeway (Bakersfield, Roseville, Folsom, Simi Valley, Temecula, Bonney Lake, Silverdale) for the gaps.
- Print-friendly: Letter format, big type, one state per page — prints clean in black & white.
The two gaps every I-5 diesel driver needs to know
Only 71 of 689 Costco fuel stations sell diesel, and on the West Coast's main road-trip route they cluster around the cities. Two stretches have no Costco diesel at all:
The PDF also flags the third-longest stretch (Elk Grove → Redding, 162 miles) and marks every gap over 120 miles in red in the station tables.

Who it's for
Diesel RVers chasing the cheapest clean diesel on the West Coast (see our diesel RV road-trip guide), truck drivers who fuel at Costco where the rig fits, and Costco members towing boats, campers or equipment up and down the coast. If your diesel truck can't comfortably do 370 miles between fills, this planner is the difference between a fuel plan and a fuel problem.
- Scepter 5-gal diesel fuel container — legal spare diesel for the 369-mile gap
- Hot Shot's Secret Diesel Extreme — the additive we run on long trips
- 6000A jump starter with air compressor — dead-battery insurance in the Siskiyous

Diesel availability and hours can change, so call ahead on long legs. Edition 1 covers I-5; I-10 and I-95 editions are next.
