For Duramax owners, understanding the complexities of your Diesel Exhaust Fluid (DEF) system is the first step toward safeguarding it. A little knowledge can help to reduce cryptic fault codes that can trigger derate countdowns and expensive dealer quotes. It’s within these nuances that you’ll find the best DEF fluid for your Duramax engine. Which …
Maintaining peak engine performance across modern diesel rigs starts with keeping your aftertreatment system clean. Distinguishing an electrical sensor glitch from compromised fluid lets you make accurate maintenance decisions early on. Finding the best diesel exhaust fluid (DEF) for Cummins engines requires understanding how your selective catalytic reduction (SCR) system operates and how the right …
One minute, your truck is pulling like normal. Then, a warning light pops up, and the dashboard starts counting down miles. Ignore it long enough, and your truck’s computer takes matters into its own hands — restricting how your vehicle performs, if you can keep driving at all. That’s typically what happens when diesel …
If you drive a diesel truck, tractor or piece of heavy equipment built after 2010, you’ve probably noticed the blue-capped diesel exhaust fluid (DEF) fill port next to your diesel tank. DEF is the working fluid that your selective catalytic reduction (SCR) system uses to clean nitrogen oxide (NOx) emissions and keep your diesel running …
As your diesel vehicle ages and puts on more miles, it only makes sense that its fuel efficiency will begin to drop sharply, right? Actually, miles per gallon (MPG) is a measurement used to determine your vehicle’s fuel economy. It reveals how many miles a vehicle can travel with a single gallon of fuel. A …
Whether you’re hauling a camper or carrying supplies, your diesel vehicle is designed to handle heavy loads. However, most modern diesel engines have highly sensitive, high-pressure fuel systems that are vulnerable to contamination and have lubricity issues. Fuel system maintenance remains the best way to enhance performance and longevity, while avoiding catastrophic failures and multi-thousand-dollar …
Declines in engine performance could stem from your fuel. Modern ultra-low sulfur diesel (ULSD) strips away the lubricity and affects the cetane that diesel engines depend on, and standard pump gasoline leaves behind carbon deposits on injectors, valves and pistons with every fill-up. Fuel injector deposits can impact fuel economy, and burning more fuel costs …
Most diesel drivers operate under a simple assumption — if it’s at the pump, it meets spec. They trust the gas station to sell quality fuel, but what’s available at the pump may not meet their standards. The legal minimum for diesel fuel quality and what your engine actually needs are different. Federal law sets …
Your truck starts fine. The engine runs. You fill up, drive and enjoy consistent engine performance. If everything seems fine now, why add anything to the tank? Rather than creating immediate problems, skipping fuel additives means effects accumulate slowly, over thousands of miles, in ways you won’t notice until the damage is already done. By …
