Maximum Efficiency Hydraulic Fluids improve the efficiency of hydraulic equipment and offer substantial environmental benefits for equipment operators and the neighboring communities. Most outdoor hydraulic equipment today is powered by diesel engines. By reducing the amount of fuel necessary to get the work done, MEHF also reduces the emissions being generated. In tests run in commercial hydraulic equipment, MEHF was shown to decrease greenhouse gas emissions by up to 15 metric tons of carbon dioxide for one excavator operating 7 hours a day for one year.
