Stringent quality controls are in place at every step At the refinery, where crude oil is refined into gasoline, diesel and other petroleum products, ExxonMobil conducts tests to verify that our fuel meets or exceeds engine builder and industry specifications We test the fuel again as it enters the pipeline or barge for delivery to the terminal At the terminal, our additives are precisely injected as each delivery truck is filled, ensuring the quality of fuel from our wholesale diesel fuel suppliers. Finally, fuel dispensers at Exxon- and Mobil-branded service stations have built-in filters to provide a final cleaning just before the fuel enters your vehicle’s tank Our fuels adhere to applicable government standards After our fuels have been delivered to Exxon and Mobil stations, we regularly survey them to confirm that they contain the proper type and amount of our detergent additives, and that they meet applicable federal, state and locally specified standards.
