The ...Automotive fuels derived from petroleum propel our cars by converting the energy of combustion to heat and work. The challenge for an efficient, powerful engine is to maximize the work available. The second law of thermodynamics teaches this can be done by designing engines with high compression ratios. However, problems of uneven fuel combustion and knocking must be overcome through fuel reformulation or by finding an appropriate additive.

For the most part, we are comforted by the fact that we can at least observe the macroscopic. Here is a wonderful representation of the way chemical reactions take place that may help you understand chemical kinetics and thermodynamics.
