No. Green Plus actually lowers the temperature of the combustion process. This is done by lowering the temperature needed for the fuel to combust by enabling the oxygen in the air to more completely combine with each hydrocarbon molecule. This means that more energy is available for the expansion from the combustion process producing more work or power and thus less heat is created. You can see the results of a horsepower test conducted by William Adams (the sole distributor of Caterpillar engines in Australia) on Green Plus by clicking here.
