What Fleet Owners Need To Know About PC-11

By now, you’re probably already using PC-11 or are about to. To date, ExxonMobil has accumulated more than 27-million miles of testing on its CK-4 and FA-4 PC11 diesel engine oil blends. The main thing fleet owners need to remember is there are two sub-categories, CK-4 and FA-4: • CK-4 – replaces CJ-4 oils, is a higher-viscosity blend with the high-temp, high-shear qualities needed for older-style diesel engines and is back-serviceable. • FA-4 – In order to meet increasing emissions and fuel efficiency standards, new diesel engine designs will benefit from using a lower viscosity engine oil. FA-4 does...

Keep Your Lubricants Ready For Use: Fluid Storage Best Practices

In the world of lubricants, inventory costs are a universal concern in an industry that has forced many companies to go lean. Protecting inventory is critical and proper storage of lubricants will insure quality and prevent waste. Following lubricant storage best practices will help increase efficiency in your operation. Cool, Dry Storage While climate-controlled is best, keeping fluid storage containers indoors out of the elements is the next best option. Direct sunlight can heat fluids to over 150F causing premature oxidation which can lead to additive insolubility and varnish. Also, temperature fluctuations can cause containers to expand and contract,...

Prepping Diesel Fuel Tanks For Winter

Diesel fleets depend on clean, moisture-free fuel to stay running their best, especially when temperatures start to drop in winter. Moisture in a diesel fuel system can cause numerous problems including bacteria growth, filter plugging and, in colder temperatures, icing. The summer of 2016 in the Midwest was wet and humid, and that moisture and humidity combine to create problems in diesel fuel tanks and dispensing systems once temperatures start to drop. Moisture More moisture means a better environment for bacteria growth. Bacteria create waste, which can cause corrosion and clog filters. Test your tanks annually or, better yet,...

Treat DEF How You Treat Fuel

Fuel is the energy that drives any fleet. Fluctuations in fuel price can mean big changes in fleet operations. For businesses that run diesel fleets, DEF is equally as important as fuel, and managing DEF supply is equally as critical to successful operations as managing fuel supply. To keep NOx emissions in check, most manufacturers have turned to Selective Catalytic Reduction systems that inject Diesel Exhaust Fluid (DEF) into the exhaust to break down NOx into nitrogen and water. DEF is 32.5% urea and 67.5% de-ionized water. While simple, it’s a specialized fluid that, like diesel fuel and oil,...
