Gas Prices in Cary, NC Today

Cary drivers are paying around $3.20–$3.35 per gallon for regular unleaded in late March 2026, near the North Carolina state average of roughly $3.30 and about 55–70 cents per gallon below the national average of $3.91. As one of the most affluent planned communities in the Southeast and the suburban anchor of the Research Triangle, Cary has a gas market that might surprise you: despite high household incomes and a premium-brand-heavy retail landscape, the actual pump prices here are very competitive.

Why Cary's Gas Prices Are Low Despite High-Income Demographics

The conventional wisdom is that wealthy suburbs pay more at the pump, fewer price-sensitive consumers, lower station density, premium branding. Cary partially inverts that pattern. The Research Triangle's tech and pharma workforce is analytically minded and comparison-shops everything, including gas. When your commuter base includes engineers, data scientists, and finance professionals, a significant share of them will actually calculate per-gallon costs before filling up. That behavior keeps stations in Cary from extracting a substantial premium.

The physical reality helps too. Cary sits at the confluence of I-40 and US-1, both of which carry heavy Research Triangle commuter traffic. High-volume corridors generate high-volume gas demand, and that volume compresses margins. The Crossroads area, where I-40 meets US-1/64, is one of the highest-traffic commercial nodes in Wake County, and the station cluster there is among the most competitive in the Triangle.

North Carolina's low gas tax structure applies here identically to the rest of the state, about 40 cents per gallon combined (below most major states), and Colonial Pipeline reaches the Triangle efficiently through the Charlotte-to-Raleigh distribution corridor.

Where to Find the Cheapest Gas in Cary

The Crossroads area at I-40 and US-1 is the anchor for cheap gas. Kildaire Farm Road and Walnut Street corridors in the older parts of town have solid competition. Avoid the boutique commercial areas near Preston and MacGregor where station density drops and pricing slips upward.

Costco at Crossroads

The Costco at the Crossroads shopping complex in Cary is the single best gas option in the Research Triangle for members. It's located directly at I-40 exit 290, making it easy to combine with a shopping trip and almost effortless to access during a commute. The Cary Costco fuel station regularly undercuts the Wake County average by 20–35 cents per gallon. For Triangle commuters doing 12,000–15,000 miles per year, a Costco membership is one of the better fuel economics decisions available.

RTP Commute Timing

The Research Triangle Park sits just northwest of Cary along I-40 and Davis Drive. RTP employers run large shift populations that create predictable peak demand periods around 7–9 AM and 4–6 PM. Stations along the Davis Drive and McCrimmon Parkway corridors near RTP see the sharpest demand spikes during these windows. If you're filling up near RTP, midday or off-peak timing will be faster and occasionally slightly cheaper due to lower impulse demand from commuters.

nA tire pressure gauge is one of the cheapest ways to improve fuel economy, properly inflated tires save up to 3%. And a phone mount makes navigating to the cheapest station hands-free.
