Quizplus · Accepted Answer

Technician A is correct because gasoline at a busy station is less likely to have been sitting for a long time, which can result in degraded fuel quality. Additionally, overfilling the vehicle's tank can result in fuel reaching the vapor canister, resulting in damage to emissions components. Technician B is incorrect because oxygenated fuels are designed to help reduce CO emissions, not increase them.
