Why is diesel more expensive than gas can anyone explain it? I'm talking fuel....but yes engines is the same question.
Diesel fuel use to be cheaper, but what changed the equation is the EPA’s low sulfer requirement...To reduce sulfer to ultra low levels in diesel requires private investment and the construction of new multi-million dollar hydrotreating units where sulfur is bonded onto Hydrogen thereby converted into H2S gas for removal...The capital to build these costly units must be recouped at the commercial pump...
