Keeping up with oil & fluid changes can sometimes fall by the wayside when you’re doing long-haul deliveries or managing a fleet. But issues when it comes to oil & fluid levels or condition can be both a cause and an effect of further problems with your truck or fleet. Here are some common problems to look out for so you know when you need oil & fluid changes or further maintenance.

Common Signs of Oil & Fluid Problems

Poor Quality Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is a type of engine fluid used to help reduce the amount of air pollution produced by a diesel engine; it’s used in the selective catalytic reduction (SCR) that helps lower NOx emissions. However, low-quality DEF can cause significant damage to your truck and quickly increase repair costs. If DEF deteriorates, it can increase DEF consumption or reduce its effectiveness in addition to causing SCR system malfunctions or complete equipment failure. The quality of diesel exhaust fluid can be affected by crystallization, which can occur when too much DEF is present and can be detected by inspecting your truck’s exhaust piping visually, or more basic things like contamination from dirt, metal, and other fluids such as diesel fuel. Your DEF is suffering from the former if it appears cloudy or colored and the latter if it has a distinct diesel smell. You should replace the diesel exhaust fluid immediately to prevent further damage and/or issues.

Suspect Transmission Fluid

Just as your transmission is an important part of transferring power from your engine to your wheel, transmission fluid is an important part of making sure your transmission’s parts run smoothly and stay cool. However, transmission fluid can be both a cause and a sign of transmission issues. For example, if your transmission fluid isn’t its typical bright red color but rather darker and opaque, then that may be a sign of transmission issues. On the other hand, transmission fluid loses its friction reduction properties over time which can cause an overheating problem; this has the follow-on problem of causing a burning smell due to the fluid burning from the transmission’s heat. Ideally, transmission fluid should be changed every 100,000 kilometers (roughly 62140 miles) or any time you get your oil and the rest of your fluids checked.
