Nearly every gas station in New York City is failing to provide properly labeled gasoline, according to recent inspections. This widespread issue can lead to engine problems and drivers being ripped off. Here’s what you need to know.
### Background
Inspectors from New York City's Department of Consumer and Worker Protection (DCWP) found widespread issues at gas stations between 2023 and 2025. These inspections involve checking fuel quality and ensuring accurate labeling.
### The Problem: Mislabeled Octane
The primary issue is gas stations selling lower octane fuel while advertising it as premium. This can happen due to accidental or intentional mixing of fuel in underground tanks.
### Why This Matters
### How to Prepare
1. **Know Your Car's Requirements:** Check your vehicle's manual for the recommended octane level. 2. **Look for TOP TIER Stations:** Choose gas stations with TOP TIER certification, indicating higher quality fuel with detergents. 3. **Be Observant:** If you notice your car is not performing as expected after filling up at a particular station, consider switching to a different one.
