Where are you getting such high numbers? Using the spot prices listed on the EIA website for 7/5 of
$2.963 for Gulf Coast ULSD
$2.731 for Gulf Coast gasoline and
$103.09 for WTI at Cushing
yields a 3-2-1 crack of ~$14.83
Avery day on my excel spreadsheet I calculate the 3.2.1. crack as per IEA meaning with LLS, also the crack with WTI and the Brent using the 2.1.1. You have to use the IEA GOM gasoline price and diesel. If you use the lowest price WTI and the highest Gasoline and Diesel, the crack will be larger. This is the case with LLS which is priced higher than even Brent. On the other hand LLS is heavy crude fetching more diesel.
ALDW does not buy LLS but WTI from the Permian and at a discount. I do not know ALDW discount. Friday July 12 the crack was: WTI = $20.95 per barrel. LLS = $16.57 per barrel. Brent = $34.38 per barrel. My guess is that ALDW crack should be higher, if you know their WTI feedstock discount.
