   Want Better MPG From Your 3.0 Duramax? Stop Buying This Stuff

   Will an aftermarket part actually increase the fuel economy of your 3.0 Duramax? How can you get better MPG without wasting money on modifications that may never pay for themselves?In Episode 32, I break down what I’ve learned from testing different parts and modifications on the 3.0L Duramax diesel. We’ll talk about air intakes, air filters, fuel additives, the Edge EZX, PPE charge air cooler, tires, wheels, driving habits, maintenance, and what I believe actually makes a difference when you're trying to improve fuel economy.The 3.0 Duramax is already an incredibly efficient diesel engine, but with diesel prices climbing, every MPG counts. The important question is whether spending hundreds of dollars on a modification actually saves enough fuel to justify the cost.I also cover a few updates before getting into our main MPG discussion, including the LM2 vs. LZ0 pistons, what I found after cutting open my 10L80 transmission filter, oil supply concerns, fuel filters, and some new products.Filters: https://www.demonworkshop.com/collections/oil-and-filtersKlickWrench Socket: https://link.amazon/B0f5hIl4yAs an Amazon Associate, I earn from qualifying purchases.⏱️ CHAPTERS00:00 – Can You Get Better MPG From a 3.0 Duramax?01:00 – Channel & Shop Updates03:25 – Fuel Filters & Cold Weather Maintenance04:35 – Metal Found in My 10L80 Transmission Filter05:15 – Oil Supply & Rising Maintenance Costs06:20 – LM2 vs. LZ0 Duramax Pistons08:15 – How to Get Better 3.0 Duramax Fuel Economy09:30 – Do Air Intakes & Filters Improve MPG?11:20 – Edge EZX & Fuel Economy12:05 – PPE Charge Air Cooler: Does It Improve MPG?12:55 – Do Diesel Fuel Additives Improve MPG?14:20 – Tires, Wheels & Lift Kits Can Hurt MPG16:15 – Driving Habits That Improve Fuel Economy17:20 – Maintenance & Fluids Matter18:05 – Should You Buy Mods Just for Better MPG?19:10 – Final ThoughtsWhat kind of fuel economy are you getting from your 3.0 Duramax?
