Sinclair in Johnstown, Colorado is one of those underrated local gems.
If you live in Johnstown, CO or are traveling through Northern Colorado on I-25, this Sinclair is a super convenient, reliable stop. The gas pumps are easy to access, prices are competitive, and the store is always clean and well stocked.
The staff here is what really makes it stand out- genuinely friendly, fast, and consistent. Whether I’m grabbing a coffee between appointments or just fueling up on the way through town, it’s always a smooth stop with zero hassle.
As a Northern Colorado real estate agent, I’m constantly driving between Johnstown, Loveland, Windsor, Firestone, and Longmont, and this Sinclair has become one of my go-to quick stops because it’s easy to get in and out of and right where I need it.
What I appreciate most is that it feels like a true neighborhood business; familiar faces, friendly service, and well cared for.
If you’re new to the area, relocating to Johnstown, or just want a dependable local gas station with great service, this Sinclair is a solid choice. Small places like this are what make Northern Colorado feel like home.

incompetent cashier charged me twice and I never got my money back!!!! She just blamed my bank but I called my bank after a couple hours only to figure out the old lady did charge me twice she was very coy and not helpful. Don't go here unless you want your money stolen!!!!!!!!
