Yes, bad piston rings can lead to high fuel consumption. Worn or damaged piston rings can allow engine oil to enter the combustion chamber, causing incomplete combustion and increased fuel consumption. Additionally, if the rings fail to maintain proper compression, the engine may work harder, further reducing fuel efficiency.
