The national average for regular gasoline fell to $4.19/gal on June 15, according to EIA weekly data — down from $4.62 on May 18. That's a 9.4% slide in four weeks, and for most DSP operators, gasoline is the second-largest variable cost after labor.
The math is straightforward. A Ram ProMaster 2500 running 120 route miles at 18 mpg burns 6.7 gallons per shift. At the May 18 peak, that's $30.95 per van per day. At June 15 prices, it's $28.07. A 30-van fleet running five days a week saves roughly $432/week — or about $22,500 annualized if prices hold.
Cost-per-stop impact is smaller but real. Assuming 100 stops per route, the fuel component dropped from roughly $0.31 to $0.28 per stop over the same period. Doesn't sound like much until you model it across your entire annual volume.
A few things worth keeping in mind:
First, four weeks isn't a trend. EIA data shows gas averaged $4.62 in mid-May — near the seasonal high. Summer demand typically floors the spring drop, then pops again. Prices could easily bounce $0.20–$0.30 before August.
Second, Amazon rate cards are annual. The savings you're seeing now won't show up as a negotiating lever until your next renewal. What they do provide is margin breathing room — use it to build reserves, not lifestyle.
Third, if you're still running older vans at 15 mpg instead of 18+, the efficiency gap now costs you roughly $0.07 extra per mile compared to current-generation fleet. The EIA slide makes that spread visible.
