[quote="rick130remember that the centrifuge does most of the cleaning. If you cut open the full flow filter at 60,000km, I'm guessing there would be very little in there.

Actually the centrifugal filter does very little. See quote from manual.

"The Td5 engine features two types of oil filter; the main filter is a standard disposable cartridge-type full flow oil filter which is augmented with a by-pass centrifuge filter used to filter out particulate matter having a smaller diameter smaller than 15 micron but greater than 3 micron."

"Approximately 10% of the total oil flow enters the centrifuge pot through a side port in the pot casting which is mated to an outlet port at the lower side of the oil cooler housing."

I have all of the TD5 manuals on CD, including the service form. Yes those intervals are correct.

HI Disconut, I probably should have said that the centrifuge filters to a far greater level than the full flow filter, or that it filters more (as in finer) particles. Full flow filters generally only filter approximately 50% of 25-30 micron particles when tested in a multi-pass test done to the relevant ISO standar. They are a compromise of filtration vs flow.

Most nearly all by-pass type arrangements only siphon off around 10% of total flow at any one time, but they capture far, far more particles than a full flow filter because they use a much finer, (and more restrtictive) media, or they are a centrifuge like the one on the TD5.

Hi Rick,
Thanks for the clarification. In terms of filtration, the centrifugal filter removes the finer particles. (does the hard work).
Cheers,
Trev.
