Yes it's pricey and yes I dump it every 7,500kms but I like to treat the Triton as well as I possibly can in the hope she will look after me in return. So far, mostly so good.
Which valvoline are you using mate? I dumped the oil out at 1000km, and i've been using Valvoline MST 5w30 with Nippon Max oil filters. It may be overkill but its had oil and filter changes at 1000km and 6000km, as I usually do it every 5000.
Here's what I posted about it back in May 2010 in this same thread (quoting from responses I got from both Penrite and Valvoline as to which oil was best for the 2.5):

Our website gets updated quarterly, so your model vehicle will be in the next upcoming update.
Based on the specifications you have provided (ACEA A3/B3 A3/B4 A5/B5 and API CF-4), it indicates that you do not actually have a Diesel Particulate Filter (DPF).
A catalytic converter may be fitted on your exhaust.
With these specifications, HPR Diesel 5 (semi-synthetic SAE 5W-40) is our recommendation.
I have attached the HPR Diesel 5 information sheet, for your perusal.
Now here's what Valvoline had to say:The specifications have not changed on your vehicle from 2009.
We are waiting on our Lubrication Advisor to update our Web Site.
Our Engine oil recommendation for your vehicle is;
Synpower 5W-40
