Recommended maintenance 

​

• Grease job every 20-25k

• Oil filter change every 30k; this is known as a “Dry Oil Change” at some service locations

• Full oil change every 60k with 10w30 semi-synthetic oil - TEL recommends Rotella t5

  The above intervals are per the manufacturer; oil changes can be done sooner, if you prefer.

• Replace the Davco fuel filter as needed (Level in the clear bowl will rise as the filter clogs).

• Replace the fuel filters on the engine about every other oil change.

• Replace the engine air filter every 90-100k miles.

• Replace the cabin air filter as needed. If you have a pet, this will need to be changed more often.

• Air dryer Coalescent filter must be replaced every 150,000 miles (Freightliner filter must be used). Failure to replace this can cause emission system related issues.

• Drain your air tanks daily to prevent moisture build up in the air system which can damage emissions and transmission components.
