About Us

The Duke of Oil

The Duke of Oil opened its first lube center in 1988 in Munster, Indiana. Today we operate 18 quick lube centers throughout Northern Illinois and Northwest Indiana. All of our quick-lube team members are highly skilled and undergo a rigorous employee certification program. The Duke of Oil employs over 150 professionals, and many of our employees have been with us since the beginning.

Still headquartered in Munster, we are a local family owned business that supports the communities we serve whenever possible by working with local vendors, suppliers and businesses, as well as sponsoring many local volunteer and school events.

AutoFix & Firestone Repair Centers

AutoFix was established to offer a complete one-stop facility for automotive repair services for virtually any make or model car or truck. With 7 locations in Northern Illinois and Northern Indiana, we have a convenient location for quick, efficient and cost effective auto repairs.

All AutoFix and Firestone locations offer a comprehensive vehicle inspection, without the inconvenience of having to visit a technician elsewhere. With friendly and reliable service from any of our ASE Certified AutoFix locations, you can trust your car or truck repairs to AutoFix.
