description: The present study examines the utilization of fuel blends comprising waste tire pyrolysis oil (WTPO) at varying ratios (10%, 20%, 30%, and 40%) in a compression-ignition (CI) engine at different loads (25%, 50%, 75%, and 100%). This is with a view to elucidating the performance and emission characteristics of the blends in detail. The performance and emission data were subjected to detailed analysis. Energy, exergy, exergoeconomic, exorgoenviroeconomic, and sustainability analyses were conducted with the objective of comparing the fuel blends. Based on these analyses, the energy dissipation of the engine, exergy losses, cost of power from the engine shaft, and sustainability index (SI) were calculated for each fuel at all operating conditions. As the fraction of WTPO in the fuel blends increased, fuel consumption increased and energetic efficiency declined owing to the lower energy content of the alternative fuel additive. As the percentage of WTPO in the fuel blends increased gradually, the exergy losses increased, resulting in a decline in exergy efficiency. At the highest load, the exergetic efficiency of TP20 was found to be 5.65% higher than that of TP40. Given that the cost of traditional diesel fuel (D100) was 73.3% higher than WTPO, the cost of power from the engine shaft decreased as the WTPO ratio ascended in the blends. Consequently, the aforementioned parameter for TP10 was calculated to be 144.55 $/GW at a load of 75% while 120.90 $/GW was found for TP40. The greatest quantity of CO<sub>2</sub> released into the environment was 11,512.4 kg CO<sub>2</sub>/month in TP40 at the highest load. Under the same conditions, it was calculated as 5,958.2 kg CO<sub>2</sub>/month for D100. In the context of an SI based on load, a reduction of 5.89% was observed in the case of conventional D100 in comparison with TP40 in the CI engine operating at full load. The findings of the present examination indicate that WTPO may be a viable alternative fuel for CI engines running on D100.
