Mistubishi Magna 2002 (Diamante) 4sp auto @ 202,000km (125k miles).
Runs though an external cooler after the radiator then back through a magnefine filter.

Not sure if I should change it just yet. It looks ok on the dipstick but appeared dark in the bottle. I think the cooler and filter are doing a good job.

Cooled and cleaned.... I'd keep running it

Change the magnefine, top off as needed and keep going.

Visc at 100c is needed.

I changed the magnefine filter at 16k miles, it wasn't that dirty so I think I changed it too early. The service book says to change the oil at 65k miles, this is without the cooler and filter. The oil isn't in great shap after that long without a cooler or filter as it comes out really black and changing it makes quite a difference to how the transmission runs.

Will keep running it and get another test with Visc @ 100c

I think Mitsubishi state 45,000km for ATF OCI

That is for 4WD models. FWD is 105,000km or 45,000km if in severe service.

2WD they state 90,000km (only example I think of is a Trition Ute).

Your probably fine running it, but if you're worried about it I would change it for piece of mind(usually easy and fairly cheap to change fluid)

I'm just worried that there are other additives in the oil which are used up but don't show on a UOA.
