Frequency of oil & filter changes, etc

[Ryan Wright]

What do you all recommend for oil & filter changes on the 8V92?

My generator manual (Yanmar/Kohler 12.5kw) says oil & filter every 150
hours, air & fuel filters at 300 hours, so I'm following that for him.
However, I don't see recommendations for the 8V. I changed everything
on it 1000 miles ago, so in terms of miles I'm OK, but time wise - I
changed it last summer shortly after I bought the coach. I doubt I'll
put more than 2000 - 3000 miles a year on the thing in the near term.

Also, when should the engine air filter be cleaned & what's the
procedure on that? I'm particular about maintenance and just want to
make sure I keep up with the details.

Thanks!

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.

Unlike most of the good folks on the forum I am not a fan of over
maintaining. For the most part, I'm lazy and cheap. I always looked
at the 12 month date to change factor with little reguard but did
the oilchange exersize annualy as I have a bum odometer and oil was
cheap. I never do oil analysis because I dont think I would open
the engine if the result dictated a need. Now that an oil change is
$140.00 parts I might do an oil analysis to check the condition of
the oil and need for change at my Aug 10 change date.

You never need to change the airfilter if it doesnt get dirty. This
is where time and mile prompts are of little value . My dump truck
runs off road so I air blow clean once then replace the filter
about 4 times per the year. My 94pt and most trucks have a gauge
that shows air filter issue. . I like to set the new filter in;
start the truck then try to pull it out prior to locking it inplace.
this will test for a tight seal.

FWIW, the '95 DD Series 60 has a 'forever' air filter. You blow it clean with compressed air and put it back in. In theory, it never needs to be replaced.

That's really interesting Pete. Our 97 has a disposable and we just
had it replaced for the second time in 64K miles. I know we didn't
*need* to have it done, but it wasn't all that expensive and a real
pain to change, so when I have an opportunity to get it done
reasonably, I do it.

Thank you all for the replies. I'll go ahead and stick with once a
year, then, unless my mileage increases dramatically.

Ditto here Paul. My '02 has the factory OEM paper disposable unit.

Under the conditions I subject my coach to, the paper element lasts a

long time: 100K plus miles. In fact, they work better once broken in;

i.e., once they've accumulated a layer of outer dust which functions

as a prefilter.



The folks over on the DetroitDiesel forum strongly recommend

against the aftermarket cleanable lifetime air filters.

As far as I can tell, the 'forever' filter on my DD Series 60 is an OEM unit. They may have had second thoughts after going with it or it was a Blue Bird idea at the time.

Pete, that brings up a good point about taking part numbers off a
broken or worn part to make a change. You can not tell if the PO
(previous owner)used the correct replacement. The forever cleanable
filters are good but if you blow air inward the sharp dust may clog
or open holes in the fabric. I bet owner-operators do a good job
but employee drivers and shop techs may not cop to blowing a hole
in a $250.00 filter. You can tell if the filter seals up by trying
to remove it with the Detroit running.
