Worn or bad spark plugs do not directly cause more oil consumption. However, if spark plugs are faulty, engine misfires can occur, potentially leading to unburned fuel washing oil off cylinder walls. This could increase oil burning slightly. It's crucial to maintain proper engine care, including regularly checking and replacing spark plugs, to avoid such issues.
