Fill Up With New Sinclair Gasoline Large 30-Inch Porcelain Enamel Sign

Sinclair Gasoline – Fill Up with Nickel Power

Back when dinosaurs ruled the fuel world (literally), Sinclair was pushing innovation and advertising with style. This bold 32" porcelain enamel sign celebrates their Nickel Compound blend—a fuel additive that promised more power, cleaner engines, and better performance. The proud Sinclair Dino charging across the design brings back memories of two-lane roads, full-service stations, and fuel you could actually trust.

It’s more than a sign—it’s a time capsule from the golden age of American motoring.

Remember when people were proud to own things? When American-made meant something?

We do too. That’s why we don’t cut corners. This Sinclair Nickel Compound 32” Porcelain Sign is made exactly like the originals—real kiln-fired porcelain enamel, layered on ¼-inch heavy-gauge steel for a glossy finish that won’t fade, flake, or peel.

Built Like the Originals—Because It Is.

After 15 years in the auction world and a lifetime as a collector, I’ve seen all the shortcuts—flimsy aluminum, sticker overlays, factory fakes. We do it the old way: heavy in your hands, timeless on your wall, and true to the original era. Weighing in at 18–22 lbs, this sign includes hand-punched mounting holes for an authentic vintage feel.

Key Features:

✔ 30” diameter – Oversized and eye-catching for your shop, garage, or collection
✔ ¼” heavy gauge steel – Built for serious collectors and built to last
✔ Kiln-fired porcelain enamel – Fade-resistant, weatherproof, and beautifully glossy
