https://www.duramaxnews.com 3Max 3.0 Duramax had some big updates come up in the past few weeks. Engine Oil pan has been redesigned and DEF warnings on the dash have been corrected with calibration changes. We discuss a new engine oil that will be run in the 24 ZR2 to see how well it performs (Motul 5w30). We answer a question from a viewer about a def injector replacement and discuss the move !
Did the EPA just make diesel deletes legal?Over the last few days, headlines about the 2009 Endangerment Finding being rescinded and auto start/stop credits being removed have caused a lot of confusion in the diesel world. Many 3.0 Duramax owners are asking whether emissions rules were rolled back and whether DEF or DPF systems could be going away.In this episode, I break down what was actually rescinded, what it means legally, and — just as importantly — what it does NOT change.We discuss:• What the 2009 Endangerment Finding was• How greenhouse gas regulation differs from diesel aftertreatment standards• Why the Clean Air Act still matters• What the anti-tampering provision means for deletes• How Right to Repair fits into the conversation• What would actually have to happen for emissions removal to become legal• And what 3.0 Duramax owners can realistically expect moving forwardI also share real-world experience from my 2024 LZ0 and how calibration updates are quietly refining the platform year over year.
Is 300,000 miles on a 3.0 Duramax realistic, or just a fantasy? In this episode of DemonWorks, we move past the internet rumors and break down real-world reliability data from over 200 owners. We reveal the actual failure rates of the LM2 and LZ0 engines, identifying what breaks, what lasts, and who is actually hitting high mileage.Plus, we dive into your technical questions: How to properly configure your Banks iDash for towing vs. daily driving, diagnosing phantom idle vibrations on the LZ0, and why some owners are smelling dangerous exhaust fumes in the cab during regen.www.duramaxnews.comhttps://www.bankspower.com/demonworks hrtps://www.duramaxnews.com Will the 3.0 Duramax really last 150,000… 200,000… even 300,000 miles?Real owner mileage data from 200+ trucks.In this episode of the 3.0 Duramax Diesel Podcast, I break down actual owner-reported results from public forums and Facebook groups to answer the biggest question I get asked:👉 How long does the 3.0 Duramax REALLY last?This discussion is based on documented mileage reports, not hearsay. We analyze what’s actually failing, what isn’t, and why Facebook can make reliability look worse than it really is.🚛 What We Cover in This Episode✅ Can the 3.0 Duramax realistically reach 150K, 200K, or 300K miles✅ Results from 200+ owner-reported trucks (LM2 & LZ0)✅ Common issues vs. rare failures✅ Why most problems are system-level, not engine failures✅ Real high-mileage examples (200K–300K+ trucks still running)✅ Why social media amplifies failures — not failure rates🔧 Listener Questions AnsweredBanks iDash Setup (3.0 Duramax)• What data actually matters• Best gauge layouts for daily driving vs towing• Regen tracking, EGTs, oil pressure, air density explainedIdle Vibration on LZ0• Why vibration at idle happens• GM’s diagnostic approach• Engine mounts, exhaust contact, injector balance & fuelingExhaust Smell in the Cab• Why exhaust fumes are more noticeable during regen• Common leak points (turbo clamp, DPF joints, backpressure valve)• What to check and when to involve the dealer🧠 Bottom LineThe data shows the 3.0 Duramax engine itself is not the weak link.High-mileage trucks already exist — they’re just quieter than the complaint posts.The real question isn’t “Will it last?”It’s “How much modern diesel complexity and downtime are you willing to tolerate?”🔗 Helpful Links & Resources• Demon Works YouTube Channel• Duramax News Blog: https://duramaxnews.com• Demon Works Shop: https://demonworkshop.com• Email questions via the links in the description📩 Have a question you want answered on the podcast?Drop it in the comments or send it through DuramaxNews.com.👉 Subscribe for weekly 3.0 Duramax tech, diagnostics, and real dealership insight.ACDelco Fuel Filter: https://amzn.to/3QFfXex3.0 Duramax Oil Change W/ PPE Oil Filter: https://amzn.to/3qmLR6o3.0 Duramax Oil Change W/ ACDELCO: https://amzn.to/3QtmDO5PPE OIL FILTER: https://amzn.to/3JP9j22 - BE SURE YOU ARE BUYING FROM PPE ONLY - CHECK SELLER NAMEFuel Filter Socket: https://amzn.to/4b52BkYFuel Filter KlickWrench Socket: https://amzn.to/42arKH6Aluminum Fuel Filter Cap: https://amzn.to/3FZir28K&N Air Filter: https://amzn.to/3S5sLvqK&N Fuel Filter: https://amzn.to/4b6Ux3ihttps:/www.maxl.com/demonworks https://www.bankspower.com/demonworksBANKS DISCOUNT CODE "DemonWorks"WEIGH SAFE HITCH: https://www.weigh-safe.com/product/weigh-safe-drop-hitch/?affiliate=demonworksALSO USE Discount Code DW10 at weigh-safe.com www.bankspower.com/DemonWorkswww.duramaxnews.comwww.bankspower.com/demonworksAs an Affiliate / Influencer, I earn from qualifying purchases.

Aftermarket intakes on the 3.0 Duramax generate a lot of questions — and a lot of misinformation. In this episode, I answer the most common intake questions owners ask, including power gains, MAF accuracy, EGR interaction, MPG changes, intake design, and why sound doesn’t always equal airflow. This is a data-first, no-hype discussion focused on how the 3.0 Duramax actually uses airflow and sensor data to make decisions.https://www.demonworkshop.com/products/2020-2025-gm-3-0l-duramax-diesel-fuel-cap-173001000Amazon Fuel Cap: https://amzn.to/4iSznKiACDelco Fuel Filter: https://amzn.to/3QFfXex3.0 Duramax Oil Change W/ PPE Oil Filter: https://amzn.to/3qmLR6o3.0 Duramax Oil Change W/ ACDELCO: https://amzn.to/3QtmDO5PPE OIL FILTER: https://amzn.to/3JP9j22 - BE SURE YOU ARE BUYING FROM PPE ONLY - CHECK SELLER NAMEFuel Filter Socket: https://amzn.to/4b52BkYFuel Filter KlickWrench Socket: https://amzn.to/42arKH6Aluminum Fuel Filter Cap: https://amzn.to/3FZir28K&N Air Filter: https://amzn.to/3S5sLvqK&N Intake: https://amzn.to/4b6oy35K&N Fuel Filter: https://amzn.to/4b6Ux3ihttps:/www.maxl.com/demonworks https://www.bankspower.com/demonworksBANKS DISCOUNT CODE "DemonWorks"WEIGH SAFE HITCH: https://www.weigh-safe.com/product/weigh-safe-drop-hitch/?affiliate=demonworksALSO USE Discount Code DW10 at weigh-safe.com www.bankspower.com/DemonWorkswww.duramaxnews.comwww.bankspower.com/demonworksAs an Affiliate / Influencer, I earn from qualifying purchases.

Welcome to Episode 4 of the 3.0 Duramax Podcast — built for new 3.0 Duramax (LZ0/LM2) owners and anyone using their truck for heavy-duty work like towing, long idling, or snowplowing.https://www.bankspower.com/demonworks Discount Code DemonWorkshttps://www.duramaxnews.comwww.archoil.com Discount Code DemonWorkswww.weigh-safe.com Discount Code DW10The break-in period (what GM says at 500 miles vs real-world break-in expectations)When to tow, RPM limits, and what to avoid early onFirst oil change + rear differential break-in thoughtsRegen explained (DPF self-cleaning): what you’ll notice, what’s normal, and what to do if a message appearsDEF tips (how to avoid costly mistakes + storage/freshness basics)Reliability upgrades for extreme use: monitoring temps, charge air cooling, transmission cooling/capacity, and maintenance prioritiesDrop your experience in the comments — especially if you’re a veteran owner — so we can keep building the strongest 3.0 Duramax community.
In this episode, we take a deep dive into the LZ0 3.0 Duramax thrust bearing failures that have been making waves across the diesel community — specifically affecting some 2025 and 2026 model year trucks and SUVs.I break down what’s actually happening, what GM has (and hasn’t) said, and share my real-world observations as a GM technician who has seen these failures firsthand. We talk about what a thrust bearing does, why these engines fail when they do, and whether this is something owners can realistically catch early.This episode also answers common owner questions, including:Is there any warning before failure?Can oil analysis catch it?Does making it past 10,000 miles mean you’re safe?Should you avoid buying a 2025–2026 LZ0?Would I still buy one myself?This is a community-focused discussion, based on real data, real failures, and real ownership concerns — not internet speculation. If you own a 3.0 Duramax or are thinking about buying one, this episode will give you clarity, context, and confidence.Have questions for the next episode? Leave a comment — they shape future shows.
In this episode, I answer three listener questions that are better suited for the podcast format, including when it actually makes sense to use a block heater, what the “best” year of the 3.0 Duramax really means, and how certain topics are handled differently on the podcast versus YouTube. We also start a broader discussion around emissions deletes—why the topic comes up so often, how it’s commonly misunderstood, and why context matters—without getting into instructions or recommendations.I also briefly reference my latest video explaining blowby and the closed PCV system on the 3.0 Duramax, and why visual checks like popping the oil cap can be misleading on modern diesel engines.In the next weekly episode, I’ll take a direct look at the LZ0 3.0 Duramax and address a question many owners are asking right now: is it actually a bad engine, or is important context getting lost online?
In this episode, I answer real viewer questions pulled directly from YouTube — the same questions I hear every day as a GM technician.We cover 5W-30 oil use in the 3.0 Duramax, early oil changes and engine break-in, blowby expectations, LM2 teardown findings, LZ0 improvements, long-term wear concerns, engine swaps, and what the future looks like for the 3.0 Duramax platform.No speculation. No warranty talk. Just practical, real-world answers based on what I’m seeing in the shop.Duramax® is a registered trademark of General Motors.
