Better to ask the engine manufacturers than the 'accessory' manufacturer,
IMO.
Most if not all the major diesel engine manufactureres offer by-pass filters
as options. This filter, as they state, will allow for extended oil drain
intervals IF combined with an oil sampling program.
So how's that for double speak??? In a nutshell if you have a by-pass
filter, and I personally think the GC filter is better than the factory
offered ones, then you need to establish a known change interval under your
operating conditions that keeps the oil at the manufactures require
condition level.
In many diesels the addition of make-up oil can keep it with-in these
guidelines for thousands of hours. OTH, if your engine uses no oil then you
need to add an additive package to keep the oil at the proper specs for your
engine.
With the advent of the tier 2 and EU/EC diesel engine specs all manufactures
are going to tighten up on what you can do to their engine while it is under
warranty. They are the one's on the hook for emmisions more than you. So
anyone fiddling/adding gear or otherwise breaking the 'seals' will cause
them to walk....and perhaps rightly so. They don't need Big Brother shutting
down an engine line cause someone added something and put the emissions out
of spec.
Some call this moving forward but others call it something else......<BG>
We have a Detroit Diesel 2 stroke whose manufacture was killed by the
watchdogs so perhaps I have a bit of bias. However, as went the DD 2
strokes, so goes all the natural 4 strokes and the non-computer operated
turbo diesel. Line em up and lay them down. Welcome the chips and the seals,
mates!
