Pennzoil—The Supreme Standard in Pennsylvania Quality

For over a century, Pennzoil has been the trusted name in motor oil, delivering unmatched protection and performance. From classic service stations to high-performance engines, Pennzoil’s Pennsylvania-grade oil set the gold standard in lubrication. This vintage-style porcelain sign is a tribute to the golden era of gas stations and automotive service, featuring bold Pennzoil branding, classic typography, and nostalgic design elements. A must-have for collectors of gas & oil memorabilia, vintage garage décor, and classic automotive advertising.

Remember when things were built to last? When craftsmanship mattered?

We do too. That’s why we don’t cut corners. This Pennzoil Supreme Pennsylvania Quality 12” Porcelain Sign is built exactly like the originals—real kiln-fired porcelain enamel, layered onto ¼-inch heavy-gauge steel for a finish that lasts a lifetime.

Built Like the Originals—Because It Is.

After 15 years as an auctioneer and lifelong collector, I saw firsthand how true craftsmanship was disappearing. Today’s market is flooded with flimsy aluminum and cheap stickers. We bring back the weight, feel, and durability of true vintage porcelain signs, with hand-punched mounting holes, thick steel, and a rich, baked-on finish.

Key Features:

✔ 12” diameter – Classic size for garages, man caves, and collections
✔ ¼” heavy gauge steel – Thick, durable, and built to last
✔ Hand-rolled edge – Just like the originals, for an authentic feel
✔ Kiln-fired porcelain enamel – Weatherproof and fade-resistant
✔ Hand-punched mounting holes – No pre-drilled factory shortcuts
✔ Weatherproof for indoor or outdoor display

Satisfaction Guaranteed.

We’re collectors too, and we know how it feels to be disappointed with a purchase. That’s why we stand behind every sign with a no-questions-asked return policy—plus, we cover shipping.
