I Investigated 7 US Truck Engine Oil Brands (Only 2 Are Worth Buying)

I spent months investigating the 7 most popular truck engine oil brands in the United States — and what I found will change how you shop forever. From Mobil 1 to Royal Purple, from Pennzoil to Quaker State, I went deep into API certifications, independent lab data, OEM approvals, and real-world fleet reports to find out which oils actually protect your engine and which ones are just marketing in a bottle. If you own a Ford F-150, Ram 1500, Chevy Silverado, or any diesel truck running a Cummins, Duramax, or Powerstroke — this video is for you. Only 2 brands made it through. The other 5 failed in ways most truck owners never expect. #TruckEngineOil #BestEngineOil #EngineOilBrands #Mobil1 #PennzoilPlatinum #ShellRotella #CastrolEDGE #Valvoline #RoyalPurple #QuakerState #TruckMaintenance #F150Maintenance
