Oil testing kits are available here
http://www.e-monitor.com.au/ for $32.50.
I've been using ALS for years, as I've mentioned on other threads, although I use a slightly more expensive test kit called 'Wear Check' which is the one aimed at heavy vehicle operators, both off and on road. As I've stated before, I'm able to take the Patrol well past 20,000km oil/filter changes instead of the book recommended 5,000km and the Landy goes 15-20,000km. I get both vehicles tested every twelve months, just to keep an eye on things.
