Hot Gas Debunked

Hot Gas Debunked
By John Eichberger

For the past few years, some reporters, consumer advocate groups and politicians have tried to convince the nation that petroleum retailers have engaged in a long-term collusive effort to cheat consumers. They claimed a gas gouge they can’t even see â€" hot gas â€" was ripping off drivers.

A standard U.S. gallon occupies 231 cubic inches. For more than 100 years, the petroleum industry has defined a stan­dard motor fuels gallon as 231 cubic inches at a temperature of 60 degrees Fahrenheit. At issue is the fact that at 75 degrees, the same amount of fuel occupies 233.3 cubic inches, while at 45 degrees, that same fuel occupies 228.6 cubic inches.

The science is clear: Gasoline mole­cules will expand and contract one percent for every 15-degree Fahren­heit change in fuel temperature (diesel fuel expands and contracts approxi­mately 0.6 percent). And a much quot­ed survey attributed to the National Institute of Science and Technology (NIST) â€" but derived from a survey conducted by an equipment manufac­turer (the raw data for which cannot be found) â€" estimated that the average fuel temperature in the United States is 64.7 degrees Fahrenheit.

These two data points launched a frenzy of activity over the last couple of years:

  • The media estimated consumers overpaid for fuel by more than $2 billion annually.
  • State legislation proposed dividing states into different regions with dif­ferent size gallons, based upon aver­age regional fuel temperatures.
  • Legislation was introduced in the Senate requiring all retailers to retro­fit their dispensers with automatic temperature compensation (ATC) de­vices within six years, with an aver­age cost per dispenser estimated at $2,000.
  • Multiple investigative hearings oc­curred in the House of Representa­tives.
  • The National Conference on Weights and Measures considered proposals to establish a method of selling petro­leum that would either allow retailers to install ATC voluntarily or require ATC installation within 10 years.
  • The U.S. Government Accountability Office released findings from its re­port assessing existing information.
  • More than 50 defendants were named in class action litigation claiming widespread collusion and coordinat­ed deceptive practice to defraud the consumer.

This debate, based upon broad assumptions, unreliable estimates and unsubstantiated allegations, can finally be put to rest with the early 2009 release of two definitive economic analyses:

  1. Fuel Delivery Temperature Study," prepared by the California Energy Commission (CEC), and
  2. An Economic Analysis of the Cali­fornia Energy Commission Staff’s Fuel Delivery Temperature Study and the ‘Hot Fuel’ Allegations prepared by Mike Flynn, principle at LECG.

These two reports reviewed the al­legations made in the debate over "hot fuel" and automatic temperature com­pensation and analyzed the economics affecting the petroleum marketplace.

Thankfully, the conclusions completely refuted the charges levied against the industry by the media and consumer groups.

What happens now remains to be seen, however. While there’s been no further action on federal legislation, the litigation continues, the National Con­ference on Weights and Measures votes on the issue this July, and many state leg­islatures are now in session. Hopefully, this new information will resolve the hot fuel issue once and for all.

Key Findings from the Reports

Retailers Do Not Generate "Hot Fuel" Profits.
At the core of the hot fuel (also called hot gas) debate is the allegation that re­tailers are collecting billions of dollars from consumers for fuel that consum­ers never receive. In its exposé on the issue, the Kansas City Star used NIST state-level temperature data and the average retail prices on July 31, 2006, (the national average was $3.01 per gal­lon) to calculate how consumers have "overpaid" more than $2 billion annu­ally. These estimates have been used repeatedly in allegations of retailer profiteering. However, in his analysis, Mike Flynn with LECG proved that such excess profits were "illusory."

Figure 1 demonstrates that alleged hot fuel profits in many states exceed the average total pre-tax profits for the industry, indicating that the conclu­sions reached by the Star were over­blown. Flynn noted, "It strains credulity to think that no one â€" not the U.S. Com­merce Department, the Internal Reve­nue Service or the retailers themselves â€" appears to have noticed these phe­nomenal results."

Flynn challenges the notion that re­tailers enjoyed excess profits and sus­tained these profits through collusion by quoting statistics reported by the Risk Management Association. These statistics demonstrate that "the retail stores in the ‘hot’ parts of the U.S. actu­ally are no more profitable than their counterparts in the ‘cold’ regions." No evidence supports the hot fuel profit al­legations; rather, all evidence points to the contrary. Flynn concludes: There were no excess profits.

Temperature Is Already Factored into the Retail Price of Fuel.
It’s well known that the retail petroleum marketplace is very competitive and that this competition strongly influences pricing decisions. However, each retailer must start the decision-making process with a target retail fuel price in mind. Hot fuel advocates often forget that this target price has already been adjusted for temperature variations.

Flynn explains in his report that re­tailers receive only gross liquid gal­lons, even though they might pay a temperature-adjusted net price. In other words, as Figure 3 shows, at 60 degrees the retailer receives 8,000 gross gallons and pays for 8,000 net (temperature-compensated) gallons. However, at 80 degrees, the retailer still receives 8,000 gross gallons but pays an invoice that has been adjusted to a temperature-compensated net gallon equivalent of 7,889.6 gallons.

The effect on the retailer’s target re­tail price is simple to deduce: Divide the invoice amount by the 8,000 gallons re­ceived â€" and available for resale â€" to de­termine the actual cost per gallon. Hence, at 60 degrees, the retailer’s cost is $2.875 compared to $2.835 at 80 degrees.

Consequently, the retailer’s target retail price is $3.00 per gallon and $2.96 per gallon, respectively. The consumer pays less per gallon due to the price ad­justment made to accommodate for the warmer fuel the retailer received. No phantom gallons generate excess profit.

ATC Installation Will Cost Consumers.
Hot fuel advocates claim that automatic temperature compensation devices will ensure that consumers receive all the fuel they pay for. They mistakenly as­sume that retailers would continue to sell temperature-compensated gallons at the same price as non-compensated gallons. But both Flynn and the CEC explain that retailers would have to ad­just their prices an amount equal to the adjustment in volume or risk going out of business.

For example, a 15-degree change in fuel temperature would result in a one percent volume change in gasoline, as well as a one percent change in the tar­get retail price. No retailer is going to give away free gasoline, and no compet­itor will allow a retailer to sustain in­flated profits without losing customers.

Flynn and the CEC reached the same conclusion: Installation of auto­matic temperature compensation de­vices would increase costs to consum­ers. The two reports differ in the magnitude of this cost, but the bottom line is unmistakable.

Figure 3 shows the costs estimated by CEC for implementing automatic temperature compensation. Although Flynn considers these estimates signifi­cantly underestimated, they still pro­vide a solid basis for analysis.

The CEC found that the only poten­tial benefit available to consumers would be through additional transpar­ency at retail facilities (CEC sought to assign a monetary benefit to informing consumers that the size of their gallons had changed according to fuel tempera­ture variations), which it valued at $257,729 per year â€" compared to ongo­ing costs of $7.4 million annually that would be passed through to consumers. Even when using its low-cost estimates, the CEC concludes that ATC would cost consumers more than $245 million over 20 years.

The Bottom Line
The market, as it currently functions, serves both the interests of the retailers and the consumers. Retailers post their prices on large signage at the curb, en­abling consumers to compare the price of a gallon of gas while driving by at 45 miles per hour.

This ability to comparison shop with such simplicity has empowered consumers to seek the best price in their market â€" in fact, 70 percent of consumers shop primarily on the basis of price, according the 2009 NACS Consumer Fuels Report. Consequent­ly, retailers have to be conscious of competitive positioning, and as a re­sult, provide consumers with the best value for their dollar.

The installation of ATC, as proven in two economic analyses, would do noth­ing but increase the price of gasoline to consumers and provide them with no tangible economic benefit.
