So far PA is the highest on the list and NJ is the lowest. https://www.statista.com/statistics/509649/us-states-with-highest-gas-tax-and-prices/
Cor-butthole gave us the highest gas tax to underwrite Philly transit and reward the rest of the state with neverending "structurally deficient" (translation: no bike lanes) bridge replacements.
I can’t read the Statista site, but per the American Petroleum Institute, Pennsylvania is highest, NJ is number 11, and Alaska is the lowest. This is as of 7/2/2018.
