    https://www.duramaxnews.com/post/top-dexron-ulv-fluids The 3.0 Duramax oil analysis results are IN — and they were not what I expected.In this episode of the 3.0 Duramax Podcast, I’m breaking down the results from running Motul 5W-30 for over 5,000 miles. After sending the oil out for analysis, the wear-metal numbers came back surprisingly low. We’ll look at the results, compare them to previous oils I’ve tested, and talk about what they could mean for 3.0 Duramax owners.I also got an up-close look at an Insane Diesel bypass setup featuring both the engine oil bypass and transmission bypass. Seeing this system in person seriously impressed me, so I’ll show you what caught my attention and why this setup is worth talking about.Plus, we cover:• Motul 5W-30 oil analysis and wear-metal results• Insane Diesel engine oil and transmission bypass systems• Dexron ULV transmission fluid and TRiAX ULV ATF• My upcoming premium DEF fluid test• New 3.0 Duramax tools and testing• The new Diesel Buyer’s Report project• Upcoming DemonWorks projects, products, and giveawaysTriax Ulv: https://amzn.to/4wNO2fWTriax Dexos D: https://amzn.to/4q2s0UcBlowzer Giveaway Coming Soon: https://amzn.to/4hWXt8iIf you own a 3.0 Duramax or you’re thinking about buying one, subscribe for real-world testing, maintenance information, technical breakdowns, and firsthand experience from a GM technician and 3.0 Duramax enthusiast.Let me know in the comments: Would you run an oil bypass system on your 3.0 Duramax?
