The test is from a company called Roktex and costs nothing if you use the promo code in the above link.
Seems like a pretty comprehensive test: http://www.roktex.com.au/whatIsTested.
This is not a deal at all. You get a free test kit but you have to pay for the results. Thats just normal.
I'm sending in some Selenia Racing ;)
A club member who used to sell oil, used this test the oil method to actually see when the oil was contaminated, fleet owners use it to see how the oil is going, and when it has x amount of carbon, acid, sludge and other nasties, when they change the oil, to a fleet owners oil no doubt, if you had Selenia or other expensive oil, it might be worth trying, just so you are not throwing out $120 worth of good oil, but it would depend on where the place is and how much it costs, i will still be flinging my oil after 6 months or 6,000klms or so, Colin.
$38 for the basic test.
