TEL Recommended Maintenance Intervals - Volvo:
Grease job every 20-25k
Full oil change every 45k 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 (clear housing fuel filter under the hood).
Replace the fuel filter on the engine every oil change - this is usually included with service done at T/A Petro, Love’s, and Speedco’s.
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 (the Volvo 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.
