Caterpillar bi-fuel kits: feed methane into the air intake which
reduces diesel useage by up to 70%.
Apache made a deal with Caterpillar, Halliburton and
Schlumberger to introduce these kits to fracture stimulation
while in the Caterpillar R&D stage.
Third party bi-fuel kits have been available but they may void
the Caterpillar warranty.
