What Fleet Managers Need to Know About Commercial Fluids

Manage a fleet of diesel trucks and want to extend their longevity without spending a fortune? Commercial fluids are designed to keep fleet vehicles running in top condition for longer, and they can be purchased either online or at many retailers. Read on to find out what fleet owners need to know before they choose what fluids to use in their trucks.

Ensuring Coolant Compatibility

Choosing the right coolant is essential, since not all diesel engines use the same kind. The two main types of coolant used in diesel trucks are organic acid coolant (OAT) and nitrated organic acid technology (NOAT) coolant.

There is a misconception that these two different types of coolant can be distinguished based on color alone. Unfortunately, this is not the case. Fleet managers can avoid compatibility issues by ensuring that they purchase their coolant from a reliable supplier that clearly labels all of their products.

Understanding Coolant Additives

Supplemental coolant additives (SCA) are designed to avoid cavitation and corrosion in diesel engines. Chemical concentrations can be measured using test strips to determine whether additives will be necessary, though many fleet managers find that it’s easier to simply buy coolant that comes premixed with SCA to avoid the need for frequent chemical checks.

Diesel Exhaust Fluid

Diesel exhaust fluid (DEF) is used to reduce greenhouse gas emissions in trucks that feature SCR, or selective catalytic, technologies. In order to ensure that trucks are not producing excessive nitrogen oxide, modern engines are designed to run at decreased capacity when DEF fluid levels are low, so keeping a steady supply on-hand is a must for commercial fleets. It’s also important to purchase DEF from a supplier that offers high-quality, proven fluids.

Proper Storage

Proper storage is essential for all fluids, but this is especially true for DEF. It can be stored in either a bulk container or in smaller, portable ones, but should never be stored in an unapproved container. SCR systems tend to be extremely sensitive to impurities so avoiding contamination is key.

The best way to ensure that DEF fluid is being stored safely is to purchase containers directly from a trustworthy retailer that also sells diesel exhaust fluid. These suppliers will be more likely to understand their customers’ storage needs.
