## NHTSA's summary

This bulletin provides the inspection procedure to diagnose and repair vehicles with concerns of engine oil consumption, including methods to resolve symptoms caused by carbon deposits within the engine. All internal combustion engines consume engine oil as normal part of the operation during the combustion process, depending on driving conditions and habits and mileage. Hyundai recommends regular oil changes according to factory maintenance schedules and checking engine oil levels periodically using the dipstick.
