Reminds me of the tests that Slick 50 or Duralube use to show on TV, that later through the courts turned out to be bogus.
I'm not familiar with Austrailian oil companies, so I don't know if those are everyday brands, but it kinda looks like its sponsored by RP.
RP's good oil, but IMO not worth the price. There are many guys on this forum that have gotten over 200k miles and at least one that I know about that's gotten 300k using Mobil 1, so how much better protection do you need.
I'm not a big fan of Mobil 1, I just buy the cheapest oil that meets GM4718M and most of the time that has been Mobil 1.

This is one of the oil tests that does NOT relate to actual engine conditions. The results don't mean much. I think vinegar scores well in this test!
This is known as the Falex Lubricity Tester, here is some more info on it (Note: Street Commodores is an Austrailian magazine):
"I bought this issue (March 2006) of 'Street Commodores' when I was told of the oil test. I had some concerns about the application of this test to engine oils, and the way 'Street Commodores' applied the test. I actually bought an ASTM standard - which turned out to be a slightly different test but near enough - to evaluate 'Street Commodores'' application of the one it used. I formed the opinion that 'Street Commodores' was likely to be sued, potentially by all the oil companies but Royal Purple.
In particular, the range of the "Pressure Resistance" (1540 to 295,722 psi) beggared belief.
As I recall, in its next issue, 'Street Commodores' stated that it had been advised, and acknowledged, that the test was inappropriate for engine oils. I didn't buy that issue, so I won't speculate on what else may have been said, or the circumstances which prompted the backpedalling by 'Street Commodores'."
Turns out this is a standard for very heavy viscosity oil and the method of loading (initial application of weight) determines much of the results. It is NOT very repeatable, you get widely different results with the same oil.
