Soil contamination by waste oils from automotive workshops is a significant environmental issue in Soritor, Peru, as these residues contain hydrocarbons and heavy metals that deteriorate the soil’s physicochemical properties, affect microbial biodiversity, and pose risks to public health. In this context, the objective of this research was to evaluate the effectiveness of Trichoderma sp. in reducing F3 hydrocarbons in oil-contaminated soils through an applied, quantitative, and experimental study, which included nine treatments with three doses (10, 15, and 20 ml/L) and three application times (20, 40, and 60 days). The results showed that the highest reduction was achieved with 20 ml/L at 60 days, with statistically significant differences (p < 0.05). Factorial analysis revealed that dose, time, and their interaction explained 98.6% of the variability in the results, confirming their strong influence on hydrocarbon degradation. In conclusion, the use of Trichoderma sp. is an effective, economical, and sustainable alternative for the bioremediation of soils contaminated with automotive oils, contributing to environmental health and to the achievement of the Sustainable Development Goals.
