Fluctuations in the cost of petroleum products coupled with the depletion of fossil fuel resources are placing enormous pressures on economies around the globe. Furthermore, the new emission standards for internal combustion engines that are installed on 95% of vehicles are becoming more and more stringent to move towards sustainable development goals. Therefore, finding alternative fuels is always an urgent need for any sustainable development strategy, especially recycled sources from petroleum-based incremental products such as waste plastics and waste rubber. The objective of this review is to shed light on the significant role of tire pyrolysis oils (TPOs) as an alternative fuel for compression ignition engines. Pyrolysis is the preferred solution to respond to the rapidly increasing number of waste tires globally. This work begins with production-to-adaptive perspectives of rubber tire pyrolysis oils, followed by objective assessments of the effects of this fuel’s properties on engine performance and emission characteristics considering the relevant published literature. Finally, some perspectives and recommendations are presented before concluding on the impacts and applicability of TPOs as an alternative fuel for diesel engines.
