In this study, the synergistic effect of nanoparticles with vegetable oil has been investigated for thefirst time to prevent asphaltene precipitation. For this purpose, three types of nanoparticles (Al۲O۳,Fe۳O۴, and NiO) and three types of vegetable oil have been used to change the onset of asphalteneprecipitation. Among the nanoparticles, the Al۲O۳ nanoparticle showed the best performance on thesorption of asphaltene particles and could increase the onset of asphaltene precipitation by ۵۰%.Coconut oil, hazelnut oil, and wheat germ oil were also able to increase the onset of asphalteneprecipitation up to ۴۸%, ۴۸%, and ۵۰%, respectively. The synergistic effect of Al۲O۳ and wheat germoil succeeded in increasing the onset of asphaltene precipitation and was able to increase the onset ofasphaltene precipitation and it performed better than other nanofluids
