Diesel Oil Filters Need To Be Replaced!

Using Fleetguard oil filters can reduce your risk of damage. Cummins filters are built for Cummins and many other competitive engines, Fleetguard oil filters are original equipment (OEM).

Engine oil lubricates, protects and cools internal engine components. As the engine oil gets used it changes two ways:

1. The oil becomes contaminated.
2. The viscosity of the oil is decreased. (Damaging Acid begins to accumulate)

Having your engine oil sampled and lab tested occasionally to check for contamination and viscosity, especially if you are interested in performing extended drain intervals. Contamination normally consists of one or more of the following:

1. Metal
2. Fuel
3. Soot
4. Water & Coolant

Metal Contamination – mostly from engine wear, but performing regular oil samples can foretell of possible upcoming failures.

Metal Type / Possible Component

1. Iron / Cylinder liners, rings, gears, crankshaft, camshaft, valve train, oil pump gear, wrist pins
2. Chrome / Rings, liners, exhaust valves, shaft plating, and stainless steel alloy
3. Aluminum / Pistons, thrust bearings, turbo bearings (Cat)
4. Nickel / Valve plating, steel alloy from crankshaft, camshaft, and gears from heavy bunker type diesel fuels
5. Copper / Lube coolers, main and rod bearings, bushings, turbo bearings, lube additive
6. Lead / Main and rod bearings, bushings, lead solder
7. Tin / Piston flashing, bearing overlay, bronze alloy, and babbit metal along with copper and lead
8. Silver / Wrist pin busing (EMDs), silver solder (from lube coolers)
9. Titanium / Gas turbine bearings/hubs/blades, paint (white lead)

Fuel Contamination – caused by unburned fuel in the oil. Common causes of this would be over fueling injectors, leaking injector O-rings or internally leaking engine mounted fuel pump. Most oil samples will show some normal amounts of fuel in the oil, test readings of less than 2% is desired.

Soot Contamination – basically carbon that is in the oil. Soot is most often due to incomplete combustions, which can be caused by worn piston rings or valve guides, poor fuel spray pattern from injectors, or plugged oil filter. Again, an oil sample will show some soot contamination, a test reading of less than 3% is desired.

Water Contamination – water or coolant found in the oil. Most often water is due to condensation and the amount of water will vary with engine application. Coolant should never be found in your oil. If it is, common sources of coolant would be leaking liner seals, pitted or cracked liner, internally leaking water pump, or leaking oil cooler. It is often hard to find water or coolant in the oil. This is because the oil reaches temperatures above the boiling temperature of water, causing most water and coolant to be boiled out of the oil system. Oil sample test results less than .1% is desired.
