During this unprecedented time, Mazda and Sill-TerHar would like to honor the selfless dedication of the nation's healthcare heroes in the fight against COVID-19.

In that spirit, we are honored to announce the Essential Car Care program, through which we will invest a minimum of $5 million of service costs, by offering U.S. healthcare workers a free oil change and enhanced vehicle cleaning from April 16 to May 4, 2020.
Eligible participants are all active healthcare workers in eligible U.S. medical facilities (defined below.) Medical Facilities for the purpose of this program include:
     • Hospitals, Urgent Care, Surgical Centers, Birth Centers
     • Healthcare Providers, Doctor Offices, Medical Clinics, Medical Offices, Medical Centers,

Eligibility for the program is simple. Healthcare workers will be asked to share proof

Most standard make/model passenger cars, crossovers and SUVs are eligible. The program excludes certain vehicles, including exotic vehicles, classic car vehicles, off-road vehicles, vehicles with greater than 8-quart engine oil capacity or any other vehicles with special manufacturer requirements. To ensure we can service as many healthcare workers as possible, the program allows for each worker receive the service on one car, per program period.
