A visual inspection can only reveal so much about the operating health of your equipment. But ongoing oil analysis helps you spot small problems long before they become costly repairs. That means you get more productive hours and fewer downtime headaches.

Only S•O•S Services gives you detailed information about your equipment’s oil condition, internal wear and contamination levels. Plus, get wear metal trending data specific to your machine, which quickly spots deviations and monitors gradual changes in concentration levels.

Our technicians perform comprehensive analysis on lubricated systems (engines, transmissions, hydraulics, final drives, differentials, gearboxes, compressors.) We can spot:

  • Early signs of damaging wear metals
  • Overall particle analysis
  • Condition of your oil
  • Contaminants that hurt performance
  • Total Acid Number (TAN)
  • Total Base Number (TBN)
  • Water (Karl Fischer Titration)


Some equipment users may be overlooking their cooling system maintenance or even recycling coolant to reduce disposal costs. But today’s engine operating temperatures are higher than they used to be, and smaller radiators and cooling system capacities are being designed into modern diesel engines. These and other factors are placing ever-higher demands on your coolant and cooling systems.

Problems that originate in your cooling system often spread into major issues throughout your engine, transmission or hydraulic system. In fact, about 50% of all engine downtime can be attributed to cooling system problems. That’s why it’s so critical to care about your coolant as much as your oil.

Tests and interpretation include:

  • Glycol level
  • Elemental Analysis
  • Freeze point / Boil Point
  • Conductivity
  • Nitrite
  • Magnetic solids
  • Appearance
  • Precipitate
  • Odor
  • Color
  • Foam
  • pH

Includes all tests performed in Level 1, plus:

  • Evaluating coolant chemistry
  • Elemental analysis
  • Contaminants
  • Water quality
  • Anion analysis of coolant additives & their breakdown products


Fuel quality can be a key indicator of the overall health of your system. And poor-quality fuel can affect how your equipment performs—including abnormal wear of components, valves, valve guides, piston rings, etc. This has bottom-line impacts on your maintenance and operating costs.

Beyond performance, equipment owners are increasingly realizing the value of regular fuel analysis when it comes to meeting emissions requirements. Are you putting quality fuel in your tank?

S•O•S Services and Louisiana Cat can help check your fuel quality, inside the tank and out. We offer several options to pinpoint problems before they become serious.

Periodically testing your fuel is an easy way to spot common issues like water contamination, which can lead to filter-plugging microbe growth. Prolong the life of your parts and get good insight into issues like hard starting, wear and power loss as well as Fuel Specification.

Large operations often store fuel on site for convenience. But when fuel is subjected to heat, moisture and other conditions, its quality can degrade. This service is just as handy as Fuel Monitoring for hard starting and white smoke—and it’s the best for detecting causes of rapid filter plugging, deposits, accelerated wear and low power, as well as Fuel Specification.

Go beyond the Basic to keep your productivity on track, while ensuring your machines meet emissions requirements by minimizing diesel particulates. This service is even better for insight into filter plugging, hard starting, accelerated wear and low power, as well as Fuel Specification. It also can reveal sources of white smoke and deposits.

If you’re using or storing fuel in a cold-weather environment, that can further impact its quality. It’s crucial to recognize issues such as particulate clouding early. (This service also provides robust insights about all issues discussed in other testing options.)
