Analisis Variasi Kekentalan Oli Mesin Terhadap Performa Motor Honda Beat Street 109,5 cc

Abstract

This study analyzes the effect of engine oil viscosity on the power and torque of the Honda Beat Street 109.5 cc (2022). Using a laboratory experimental method, tests were conducted on three lubricant variations (SAE 10W-30, SAE 15W-40, and SAE 20W-50) on a chassis dynamometer, employing a rapid throttle application method across a 2,000–6,000 RPM range. Pertamax RON 92 fuel was used as the control variable. Test results indicate that peak power for all three oils was achieved at 3,000 RPM, with the highest output recorded for SAE 10W-30 (8.16 HP), followed by SAE 15W-40 (8.00 HP) and SAE 20W-50 (7.90 HP). Meanwhile, peak rear-wheel torque—influenced by the CVT transmission characteristics—was achieved at 2,000 RPM. The SAE 10W-30 lubricant yielded the highest wheel torque (29.98 N.m), followed by SAE 15W-40 (25.09 N.m) and SAE 20W-50 (24.78 N.m). The study concludes that differences in oil viscosity significantly affect motorcycle performance; SAE 10W-30 proved to be the superior and ideal variation for optimizing power and torque output in the eSP technology engine of the Honda Beat Street 109.5 cc.
