diesel exhaust tailpipe tips
The exhaust tips on the 2008-and-up f-super duty diesel trucks have special exhaust tips installed at the factory. These tips should not be removed or covered with dress sleeves that will seal off the ports on the sides. the new generation of diesel engines from all makes will have some odd-looking exhaust tips on them. The tips are designed to draw cool air into the tip, by use of venturi action, to cool the exiting gases during filter regeneration.
During filter regeneration mode, the exhaust temperatures are more intense than normal. Without the special tips, the exiting gases become hazardous to the paint on the truck’s body, dry grass that might catch fire or someone’s legs who happens to be standing too close to the tail pipe.
Starting in 2008, the epa has thrown diesel manufacturers a curve ball. As part of the new regulations, these engines now have to be equipped with a particulate filter after the catalyst. The job of the filter is to trap soot. Periodically, the pcm performs a regeneration on the filter. During regeneration mode, raw fuel is injected into the filter to literally burn the soot out of the filter. The soot is reduced to ash and drops to the bottom of the filter. The ash never leaves the particulate filter assembly, and eventually, the filters will need to be replaced.

why seals fail
When a seal fails, don’t just replace it. Determine the real cause of failure. Some causes for failures, which are often ignored, are listed below:
misalignment of components.
Poor bearing lubrication.
Vibration of rotating components.
Contaminated fluid (water, acids or particulates).
Rotor imbalance or shaft whip.
Inadequate flushing procedures during commissioning or start up after repairs.
Poor, or careless seal or bearing installation.
Piping strains, due to misalignment or temperature variations.
Looseness of bolts and brackets.
Addition of incompatible fluid.
An increase in temperature (or a dramatic change in temperature).
Unclean operating conditions which cause dirt ingression.
Selecting the correct seal is only the beginning of sound equipment operation. The implementation of a sound preventative maintenance program will ensure the long life of seals, eliminating leaks and preventing environmental damage.

energy consumption
With few exceptions, lubricants and lubrication methods that reduce energy consumption will also reduce heat and wear debris generation. When heat and wear debris are reduced, less stress is imposed on additives and the base oil. The result will be longer thermal and oxidative stability, and in turn, longer oil drains, lower oil consumption and the ancillary costs associated with oil changes (as much as 40 times the cost of the lubricant itself!) - more to come on this subject in a future issue….watch for it!

avoid overfilling gearboxes
Overfilling a gearbox sump can be just as damaging as under filling. Overfilling May cause air entrainment and foam, overheated oil and leakage due to overflow. Over time oxidation May occur due to increased temperatures and exposure to air.

lube trivia:
Which particle is the hardest?
Question: which particles are typically harder, road dust or wear debris?
Answer: road dust.

there are more logical reasons to use high performance engineered lubricants than there are by comparing up-front prices. Swepco has the quality you demand, along with measurable “bottom-line” savings!
