GM’s HUGE New 8.3L Duramax Sounds MEAN! 🔊 Turn the volume UP! I’m behind the wheel of the new Chevy Silverado 2500 HD, letting you hear how this massive 8.3L Duramax diesel sounds out on the road. As a diesel mechanic, I love hearing an engine get to work—and this big Duramax has a mean growl! Come along for the drive and listen for yourself. What do you think of the sound? Would you take this over a Power Stroke or Cummins? 👇 #Duramax #83LDuramax #ChevySilverado #Silverado2500HD #DieselTrucks

Why does GM recommend 0W-20 oil in the modern 5.3L V8? The answer isn’t simply “better engine protection.” As emissions and fuel economy standards have become stricter, manufacturers have moved toward thinner oils because they reduce internal engine friction. Less friction means the engine requires less energy to turn, improving fuel economy and helping lower emissions. The modern 5.3L V8 also uses an electronically controlled variable displacement oil pump, which adjusts oil output based on engine demand. When full oil pressure isn’t required, the pump reduces its output to decrease parasitic losses, further improving efficiency and fuel economy. These technologies are very effective at meeting today’s efficiency targets, but they also highlight the balancing act manufacturers face between maximizing fuel economy and designing engines for long-term durability. What are your thoughts? Would you rather have maximum fuel economy, or would you prioritize maximum engine longevity? #GM #Chevrolet #Silverado #53LV8 #V8
