any major plant manufacturer has them, cat, volvo, hitachi, John deer and JBC are all kit packs I've seen in the ADF, I think I still have a couple of the sample kit boxes down stairs if you want the details for CAT SOS oil samplingQuote:

FWIW, all 3 diesels I've owned (1994 Delica, 2007 Kia Sorento and 1981 Nissan Patrol) turned the oil back within a few minutes of running after oil and filter change.
My BIL insists that this is how they should be; he's a diesel mechanic by trade. I used a good oil flush concentrate and the old hilux diesel's oil is still relatively clear after hours of operation. Not as clear as the TD5 but in good condition compared to how the oil behaved prior to using the flush. So even though most people reckon that's how old diesels behave, it's not necessarily correct.

How dirty the oil is after a change probably tells you more about the shape of the oil galleries and oil reservoirs inside the motor than it tells you about anything else.
Hey Chris, FYI I've just picked my Puma up from service. Here's a pic of my dipstick immediately after pickup. Looks very similar to yours I reckon, what do you think? New oil, new filter, slight residue of old oil visible, but nothing to worry about. Hope that helps.
Cheers

Mine looks a lot cleaner after an oil change because I give it a good 15 mins or more before putting the sump plug back in.
I've seen people tip a bit of fresh oil in while the sump plug is out, just to flush more of the old oil out, but thats probably over the top.
Yes agreed Beery. I also specifically drain oil warm when change my own so it flows freely, though the slight remnant oil staining the new is not really cause for concern. Cheers
