Evaluation of the effects of Gasoline-Methanol (GM) fuel blends on SI engine perfor-mance and emissions analysis was the aim of this research. Engine performance was ana-lyzed using M15 fuel blends at Wide Open Throttle (WOT) and various speed conditions between 1200 to 1800 rpm. A computerized 4s, 1cyl, VCR petrol engine test setup was used for the experimental work. The results found that the BSFC of M15 blends in-creased as much as regular gasoline for all engine speeds at full load. Exhaust emissions, including CO, HC, CO2, and NOx, are found to be minimized while engine torque and brake power (BP) is less than regular gasoline. This research recommends a methanol-gasoline blend can be an effective alternative for gasoline in transportation engines with-out requiring hardware modifications or causing major environmental harm. It found that the M15 fuel blend was appropriate for both increasing engine performance and reducing emissions.
