What this week's oil slide means for a trucker, a plow crew and a delivery van: pump diesel is still $6.29

Crude has had a hard week. The December WTI contract settled at $104.12 a barrel on Oct. 30 and was trading near $90.69 at about 10:20 AM ET on Friday, according to Yahoo Finance data, a drop of $13.43, or 12.9%, with a low close of $88.12 on Wednesday. Our War Room coverage has the geopolitics behind it: hopes for a deal with Iran, offset by fresh reports of tanker attacks. This piece is about something narrower: how much of that drop reaches an owner who buys diesel and gasoline by the gallon, and when.

The number that matters is heating oil

Diesel does not track crude directly. Its futures cousin is heating oil, and December heating oil went from $4.79 a gallon at the Oct. 30 close to about $4.31 on Friday morning, a fall of 48 cents, or 10.1%, by our arithmetic. (Crude alone explains about 32 cents of it: $13.43 divided by the 42 gallons in a barrel.) The wholesale benchmark has moved a lot.

The pump has not. The Energy Information Administration put the average U.S. price of on-highway diesel at $6.292 a gallon on Nov. 2, down only 6 cents from $6.352 a week earlier and about $2.54 above a year ago. Regular gasoline averaged $4.153, down 11.6 cents on the week. EIA's figure is a Monday snapshot, so most of this week's futures slide is not in it yet. Its next update is due Nov. 10, and that is the reading to watch.

What it is worth, trade by trade

These are illustrations on assumed usage. Substitute your own gallons.

• An owner-operator or small fleet running one tractor. A truck running about 100,000 miles at 6.5 miles per gallon burns roughly 15,400 gallons a year, so call it 15,000. If the full 48-cent futures drop reached the pump, that is $7,200 a year, or $600 a month. At the 6 cents the pump has moved so far, it is $900 a year. The gap between the two is $6,300 a year that has not yet shown up on the fuel card.
• A snow-plow or landscaping crew with three diesel trucks. Burning about 1,500 gallons each over a season, 4,500 gallons in total, a 48-cent drop is $2,160 for the season. A crew that signed seasonal contracts last month at fuel-inclusive prices keeps the saving. One that bills fuel at cost passes it to the customer.
• A bakery or caterer with two gasoline delivery vans. At 1,200 gallons each a year (2,400 total), the 11.6-cent weekly drop in gasoline is worth about $278 a year if it holds. That is real money for a small shop, but small next to a $6.29 diesel bill for the supplier that drives to it.

We hold records for 24,679 independent trucking companies, 44,163 landscaping firms and 35,649 bakeries in the CheckThisBiz directory, and the three above are why a drop in one commodity reads so differently across them. See our trucking playbook for the cost structure.

Why not to bank it yet

Futures fall faster than pump prices, but they also rise faster. The oil market is trading on Iran headlines, and the same tanker-attack reports that rattled it this week are still coming. A fall that is 12.9% in a week can be partly reversed in two days. We covered the same pattern on Monday in what Monday's oil drop means for a trucker, when pump diesel stood at $6.352. It is lower now, but only just.

What to do

1. Do not prepay or lock fuel at today's price. If the decline persists, the pump will keep falling for weeks. If you buy on a card or contract, make sure the price tracks the weekly index.
2. Check your fuel surcharge schedule. Surcharges that follow the EIA diesel average will fall on the same lag as the pump. If you bill customers on a flat rate set at the peak, the savings are yours until you reset it. If you bill at cost, expect the next invoice to show it.
3. Check the EIA figure next Tuesday. Nov. 10's reading will show how much of the 48 cents has arrived. If it is still near $6.25, the lag is longer than a week.
