Frequency of oil & filter changes, etc

[Don Bradner]

Table 4-1 of the document at
http://www.detroitdiesel.com/pdf/vocatio...ements.pdf calls
for every 15,000 miles for "Motor Coach" applications, and 6,000 miles for
"Transit Coach" applications. An RV application probably covers the spread
between those two. Note that there is no time on either, but probably that's
because an OTR coach or transit coach will hit those miles more than once per
year.

I run between 6 and 15K miles per year, and therefore choose to go with annual
replacement (and did with SOBs in the past also). My first year with an 8V has
turned out to be a 15-month year, because of the inability of CCW to get the
drain plug out, but it was only an 8K+ mile stretch so I'm not too concerned.

When you don't run even 6K miles it gets quite a bit subjective (different ideas
for everybody). I've not had any years with mileage as low as you have, so I'm
not sure what I would do if I were you.
