Put Hydrogen Peroxide HERE and Your Truck Will Thank You

There's a hydrogen peroxide hack going around for trucks. One version solves a real problem. The other costs you a fuel system. Do not put it in your tank. Household peroxide is 97% water, and water is what kills high pressure fuel pumps. A proper diesel biocide costs a few dollars and is actually tested for it. Where it does earn its place is the sleeper. If you live in your truck, you have a mildew problem whether you know it or not — and air freshener does nothing, because the smell is being made by something living. Inside: where that smell really comes from, the cabin air filter step that fixes it on its own more often than you'd think, and the safety points peroxide deserves. Keep it in the bunk. Keep it out of the tank. #truck #peroxide #mechanic
