Commando Fuels marine-grade renewable biodiesel is produced from american-grown seed oil feedstocks using a process called transesterification, where the natural oils are chemically converted into biodiesel. Our fuel is engineered to perform where conventional biodiesel fails. Conventional biodiesel has been excluded from the marine and defense fleet for two decades because of three specific failure modes: oxidation stability collapses in marine storage conditions, cold-flow behavior fails in cold-climate operations, and post-2007 engine designs reject high-blend biodiesel due to fuel system tolerance issues. Our targeted engineering is focused on overcoming the critical performance limitations of conventional biodiesel.
