From the below, I wouldn’t be surprised if mmex sells its diesel product to help produce drilling mud. Thus non combustible.

From mmex,

“Based on where we are today, we expect to be selling our three products to three different purchasers that are well known oil and products trading institutions: (i) the Diesel is being sold at our plant tailgate (ii) our Naphtha is being sold FOB to a purchaser in the Permian Basin near our plant; we will transport the Naphtha by truck to the customer and we have the arranged the truck transport, (ii) our Residual is being sold FOB Port of Houston, which we will transport by railroad on the Texas Pacifico-South Orient RR (which runs across our land) via either the Union Pacific or the BNSF. We have the truck and railroad rate quotes and we are finalizing the truck and rail agreements now.”
