I think the manual is closer to right than you are on this one.
Unless you are having problems with clogging filters.



I change the filters whenever they become restricted. That is seldom 
less than 30kmi and could be as long as 75kmi. But it only takes one bad

I change the inline fuel filter at least 3X yearly due to clogging, and at
least annually for the main filter, regardless of mileage.  Cheap fixes.

[MBZ] Fuel filter changes

2006-11-14 Thread Stephen D Murrell
How to tell; my 300D started slowing down to about 45 mph top speed  i
turned off to check filters; yes i have most all parts to fix car in
OTHER CAR!!!; I did remove main filter  dump out; then clear pre
filter; had black specks all around inside: i shook  blew thru it enough
to get home w. no more loss of power; OH! the night before i had
removed the tank screen  cleaned  checked not bad at all; then i stuck
my finger up in tank  rubbed it all around to loosen up a small layer of
sludge; only felt like thin layer???then the sludge went to pre filter,
never had a pre filter so stopped up! hadn't had this car for long;
changed  repaired a lot of other items, but did not change the
CHEAPEST?? the pre filter; i have used diesel additives also in tank;

Not really worried about it as I think my car has reasonable power for its 
type. Was just curious as to whether
there were obvious symptoms I should keep in mind as this is all fairly new to 
me.

They can slowly reduce in power overtime, or reduce suddenly. I have had
several diesels get massive increases in power after filter changes, when
I had never realized they were slowing down. Usually you will notice a
serious reduction, and difficulty climbing even mild grades. I always
carry spare filters, and the tools to change them when driving any diesel
vehicle anywhere. If you are in doubt, change them now and stop worrying
about it. It's easy and cheap to do, and then you can keep around the old
filters that still flow as emergency spares!

Tyler

 How sudden should I expect the onset? As we all know, these old cars are
 not too speedy to begin with. I might not
 notice unless it becomes fairly obvious.
 This is a 76 115 300D that I am referring to. I have had it 2 summers now
 and have yet to change fuel filters. I
 bought some and have one in the trunk but
 have yet to install one. I got some of the clear inline prefilters too but
 my car does not appear to have one
 installed at this time.

The only time you should need to do that is if you routinely buy 
seriously contaminated fuel OR the is debris in the tank that needs to 
be cleaned out.

When your car starts having less power.  The first time I experienced it
with my 83' 300D, the top speed on the highway dropped to around 65mph, and
trying to climb hills was at a significantly reduced speed.

Yes-even on my 240D I could feel the loss of power-esp. under load.
(Imagine that.)   I have also been able to see the little black flecks
in the clear inline filters-less so in the translucent ones. On my 300D
2.5t it started to miss at speed-just before the turbo kicked on.
Marshall is right-change as needed-but I carry some spares in the trunk
of both of mine.

0-60 acceleration time increases, top speed decreases, fuel consumption 
USUALLY increases (doesn't seem logical does it?) and you have shift 
sooner to get up hills. If changing the filter remedies all the 
problems, then you had a clogged filter.

Tom,
 
I would say overkill.   On a diesel, the result of a clogged  filter is 
merely a loss of power, no harm comes to the engine.  Leaning out  a gas 
engine, on 
the other hand, can burn a valve or fry a piston.  
 
I always try to carry a spare filter, as one bad load of fuel can clog  a 
filter, even the day after you change it!  I change mine at about 30,000  miles 
and have only been slowed once on a trip, in over 500,000 miles of diesel  
travel.

Depends on the diesel!  The non- common-rail 24-valve Cummins motor
used by Dodge 'twixt 98 and '-2 (?) would eat the injection pump if
the fuel filter clogged.  It has a rotary fuel-lubricated pump, however.
