This article determines the right lubricating oil for a 110-cc petrol engine. The Honda Blade was a sample for a 110-cc petrol motorbike engine. This article is aimed to be used as a guide for selecting the right type of monograde engine lubricant according to the gasoline used. Torque and engine speed measurements are carried out using a dyno meter, while fuel consumption is determined using a flow meter and stopwatch. This research found SAE 20W as the most appropriate engine lubricant to produce the best specific fuel consumption and engine thermal efficiency. The second-best lubricant option is SAE 30W. When SAE 20W lubricant and Pertamax or Pertalite fuel are used, the optimum motor engine speed to produce specific fuel consumption and optimum engine thermal efficiency is 2900 [RPM]
