Hyundai Tucson excessive oil consumption requiring one liter every 1000 kilometers on Hyundai Tucson

Some Hyundai Tucson owners report experiencing excessive oil consumption, with some engines requiring one liter of oil every 1,000 kilometers, which may indicate underlying issues. Specifically, owners of the 2017 Hyundai Tucson and models from 2016 to 2020 have reported problems linked to engine wear, oil sludge, and valve seal failures, with the 2016 model's 2.0L engine consuming up to 1.5 quarts per 1,000 miles. While some oil consumption is normal, Hyundai considers rates exceeding 1 quart per 1,000 miles as excessive, prompting the need for investigation. The recommended oil consumption for most Hyundai models is around 0.5 quarts per 1,000 miles, making it essential for owners to monitor their vehicle's oil usage to identify any issues that may require attention. Addressing excessive oil consumption promptly is crucial to prevent potential engine damage and ensure optimal vehicle performance.
