TL;DR
Automakers and environmental experts advise drivers to avoid adding accessories that increase a vehicle’s fuel consumption. These accessories can significantly reduce fuel efficiency and increase emissions, affecting both costs and environmental impact.
Automotive experts are warning drivers to avoid installing certain gas-guzzling accessories on their vehicles, citing increased fuel consumption and environmental impact. This advice comes amid rising concerns over fuel efficiency and emissions, especially as fuel prices fluctuate and environmental regulations tighten.
Several automotive and environmental organizations have issued statements urging caution against accessories such as large roof racks, heavy-duty bull bars, oversized spoilers, and aftermarket wheels that can increase a vehicle’s aerodynamic drag and weight. According to the Environmental Protection Agency (EPA), these modifications can reduce fuel efficiency by up to 15% or more, leading to higher fuel costs for drivers.
Automakers and industry experts emphasize that many of these accessories are marketed as enhancing vehicle appearance or utility but often come at the expense of increased fuel consumption. For example, a recent study by the Automotive Research Institute found that roof-mounted carriers and oversized tires are among the most common accessories that negatively impact fuel economy.
While some accessories are designed with safety or convenience in mind, experts warn that unnecessary additions that increase aerodynamic drag or weight should be avoided, especially for daily drivers aiming to save on fuel or reduce emissions.
Why Reducing Gas-Guzzling Accessories Matters for Drivers and the Environment
Choosing not to install accessories that increase fuel consumption can lead to significant cost savings over time, as fuel prices continue to fluctuate. Additionally, reducing unnecessary weight and aerodynamic drag helps lower vehicle emissions, contributing to environmental protection efforts. For consumers, this advice underscores the importance of making informed modifications that balance utility, safety, and efficiency.
From a broader perspective, minimizing the use of such accessories aligns with national and global initiatives to cut greenhouse gas emissions, especially as transportation remains a major contributor. Drivers who heed these warnings can play a role in reducing their carbon footprint while also saving money.

Recent Industry Warnings and Consumer Trends on Vehicle Accessories
Over the past year, several automotive safety and environmental agencies have increased public outreach about the impact of aftermarket accessories on fuel efficiency. The trend of customizing vehicles with larger wheels, roof racks, and other modifications has grown, but so have concerns about their environmental and economic consequences.
In 2023, the EPA reiterated that certain modifications can void vehicle warranties and lead to higher emissions. Meanwhile, consumer reports have highlighted that many drivers are unaware of how these accessories affect fuel economy, prompting calls for better education and regulation.
Automakers themselves have begun emphasizing factory-designed options that optimize aerodynamics and efficiency, contrasting with some aftermarket modifications that can hinder vehicle performance.
“Drivers should be cautious about accessories that add weight or increase aerodynamic drag, as they can significantly reduce fuel efficiency and increase emissions.”

Unclear Scope of Impact for All Aftermarket Accessories
While specific accessories like roof racks and oversized wheels have documented effects on fuel efficiency, the precise impact of less common modifications remains less clear. Industry data on the cumulative effect of multiple accessories installed simultaneously is limited, and individual vehicle models may respond differently.
Additionally, some drivers argue that certain accessories can be used strategically to improve efficiency, such as aerodynamic roof boxes, though evidence on these benefits is still limited and contested.
