We Ran an EcoBoost F-150 on Regular vs. Premium Gas for 100,000 Miles — Then Opened the Engines

Does premium gasoline actually help a Ford EcoBoost engine last longer, or are F-150 owners simply spending more money every time they fill the tank? We compare two similar EcoBoost F-150s over 100,000 miles—one consistently running regular gasoline and the other premium. We examine fuel economy, performance, engine behavior, deposits, ignition timing, long-term fuel costs, and overall engine condition before taking a closer look inside both engines. Premium costs significantly more over 100,000 miles, so the real question is whether that extra money actually buys better performance and long-term protection. #Ford #F150 #FordF150 #EcoBoost #PremiumGas #RegularGas #35EcoBoost #FordTrucks #100000Miles #EngineTeardown #F150Owners #FordMaintenance #TruckReliability #FuelTest
