As a model system, we pick the\n  Rayleigh-B\\'enard setup, filled with an oil-water mixture. For oleophilic walls, e.g. using only $10\\%$ volume fraction of oil in water, we observe a remarkable heat transport enhancement of more than $100\\%$ as compared to the pure water case. In contrast, for oleophobic walls, the enhancement is then only about $20\\%$ as compared to pure water.
