HARRISBURG, Pa. (WHTM) – New independent laboratory testing released from AAA Thursday reveals significant differences in the quality of gasoline sold at retailers.
AAA reports cheaper gasoline often lacks enhanced, engine cleaning detergent additives that can cause lower gas mileage and damage to a vehicle’s engine.
Non-TOP TIER gasoline caused 19 times more engine deposits than TOP TIER brands after just 4,000 miles of driving, according to AAA. Those carbon deposits can lead to increased emissions, lower fuel economy, and negatively affect vehicle performance, especially on newer vehicles.
