Diesel climbs into planting season

Diesel is climbing into planting season and growers are absorbing it, InForum reports. Ag is one of the heavier seasonal pulls on distillate outside of harvest, and when tractors are running long days across the Upper Midwest, that demand has to be supplied out of the same rack barrels serving freight. Haulers working farm country tend to feel the tightness first.

Surcharge lag

Most freight fuel surcharges reset weekly against a published national average. In a flat market the lag costs nothing. In a rising one the carrier buys fuel today and bills a number set last week, and the gap comes out of operating margin until the index catches up. A week of lag on a long-haul lane is real money if the move keeps going.

Fuel haulers have a version of the same problem with less flexibility. A tank wagon route priced on a delivered cents-per-gallon margin can't be repriced mid-week without a conversation the customer doesn't want to have. Carriers with weekly-indexed contracts should be checking how far behind their surcharge actually is right now rather than assuming it tracks.

Propane bus fleets

Newport News schools say moving buses off diesel to propane is saving the district money, according to 13newsnow. The story doesn't put a dollar figure or a timeframe on it. Allegany County converted its public transit fleet to propane autogas, per the Hornell Evening Tribune. Neither story gives fleet size or gallons. Together they point at where propane keeps picking up ground, which is municipal and school fleets with fixed routes and a central fill point. Those fleets run on public budgets, so fuel cost shows up in a line item officials have to defend.

For a jobber the volume moves rather than disappears. The jobber still has the customer, but on propane margin, and somebody has to pay for the dispenser. Many of these conversions have used grant money, so the economics one county over may not look the same.

Coffee grounds to biodiesel

Phys.org reports researchers found a route from spent coffee grounds to biodiesel and other bio-based products. That's lab-stage feedstock work. It may matter eventually for waste-derived diesel supply, but it isn't a reason to change the biodiesel supply plan you are buying against now.

What to watch

Watch whether the diesel firmness holds past planting or fades once the fields are in. Watch how quickly surcharge indexes catch up to the rack. The longer that lag runs, the more of the increase the carrier absorbs instead of passing it on. And watch for more school district and county transit RFPs specifying propane autogas, since two conversions inside a week may turn up in neighboring counties' budget cycles next.
