Oil change
How many mile you drive pulling the FW before you change the synthetic engine oil?

- Book says 5,000... I drive my truck 10,000 on Mobil 1 between changes.
Not all of that is towing... but most of it is now.
No change based on time, just miles. Could be two+ years between changes. - I go by my oil change message on the dash. I can scroll thru and see what my % left is.
- Follow the manufacturers' recommendation for SEVERE SERVICE in the manual.
I also use the Oil-Life Monitor (OLM).
