   HOUSTON, TX (DTN) --U.S. wholesale rack prices for ultra-low sulfur diesel 
(ULSD) finished higher on the week ended October 23, while gasoline prices were 
mixed as supply disruptions driven by the Middle East conflict continue 
pressuring fuel markets.

   Nationwide ULSD rack prices averaged $5.4283 gallon, up 15.81cts, or 3.0%, 
from the previous week's $5.2702 gallon. Conventional unleaded gasoline 
averaged $3.2768 gallon, down 6.76cts, or 1.97%, from $3.4317 gallon a week 
earlier.

   Four of the five PADD regions finished above the previous week's levels. The 
Midwest posted the strongest increase, rising 30.28cts, or 5.81%, to $5.5174 
gallon, due to supply tightness amid ongoing operational issues at ExxonMobil's 
275,000 bpd Joliet refinery

    Gulf Coast ULSD rack prices rose 23.45cts, or 4.70%, to $5.2212 gallon, 
despite Environmental Protection Agency (EPA) extended its emergency diesel 
fuel waiver in Texas through November 13, allowing continued use of 
higher-sulfur diesel in certain older engines. 

    Rack prices at the East Coast advanced 9.80cts, or 1.92%, to $5.2052 gallon.

   Rocky Mountain diesel edged up 3.37cts, or 0.59%, to $5.7527 gallon. The 
West Coast remained the highest-priced diesel region at $5.9176 gallon, 
although prices slipped 2.26cts, or 0.38%, from the previous week.

   Gasoline racks showed a more mixed regional pattern despite the decline in 
the U.S. average. The Gulf Coast recorded the sharpest weekly drop, falling 
66.21cts, or 18.02%, to $3.0120 gallon. The drop was driven by the transition 
from gasoline A3 specification toward higher-volatility A4 gasoline.  The 
seasonal transition raises the Reid vapor pressure (RVP) specification from 
12.5 psi for A3 gasoline to 14.5 psi for A4, a 2 psi increase that allows 
greater volatility in winter-grade CBOB gasoline shipped on Colonial Pipeline.

   Meanwhile, West Coast gasoline rack prices declined 42.64cts, or 10.17%, to 
$3.7672 gallon, while East Coast prices fell 5.22cts, or 1.68%, to $3.0618 
gallon.

   Rocky Mountain gasoline rack prices saw the steepest increase, climbing 
81.36cts, or 27.22%, from the previous week to $3.8023 gallon, followed by 
Midwest gasoline, which rose 7.62cts, or 2.38%, to $3.2799 gallon on the week.

   Rack prices continued tracking a weekly rally in the oil futures market 
driven by the escalating Middle East conflict. At 12:00 am ET the NYMEX WTI 
futures contract for December delivered rose $2.46 to $102.66 bbl an 8% 
increase from the previous week. 

   The diesel crack stood at $105.20 bbl Friday, compared with the gasoline 
crack at $35.85 bbl, reflecting stronger distillate refining margins.
