Redline 5W-40 not so great.
Mobil-1 0W-40 is terrible.
Valvoline DuraBlend 10W-40 is best value.

Take this with a grain of salt, and by grain of salt i mean the test is almost useless when it comes to engine oil....
google "street commodores oil test" there is some good info on bobistheoilguy.com forums with regards to this test too.Black 7M-GE 84 P-type Hardtop

link #1 and it's sub-link are of interest.
a couple clicks later you get this:
which is the actual magazine that published it. which says the following:
"If there's one thing we try and do here at Street Commodores, it's give you, our readers un-biased info on which products are good, and which ones suck. There's so much BS marketing guff out there, that it can be tough to nut out which products can walk the walk – so that's where we come in, doing our best to sort the Holdens from the Lada Nivas.
A few months back (issue 108), you might remember we did an oil comparison. At the time, we thought it was a bloody good thing, and we don't mind telling you we were pretty proud to publish an article that basically bagged a heap of big name brands. You see, at Street Commodores, we can't, and won't be bought. We like to play things straight. And in the name of playing things straight, we'd like to tell you what has happened since that story went to print.
Basically, we made a few oil companies very cross, and some others quite happy; but we've also been educated some more on engine oils, and being the type of publication that we are, we wanted to fill you in on it. The information we've learned since then suggests the test we performed may be irrelevant. Some sources have advised us that the test we used would have been better served testing some of our favourite greases rather than the engine oils we commonly use on our street cars. Sure, we did the test with the best intentions, with a level playing field for each oil and no preconceptions as to who would perform better than another, but when, and if, we mess up, we like to think that we're man enough to set the record straight.
So keep an eye out in an upcoming issue real soon for an in-depth look at what makes up the contents of your oil, what to look for when choosing one, why certain ingredients are so important and whether the test we used was irrelevant for testing oils. "Black 7M-GE 84 P-type Hardtop

here's a video where AMSOIL explains how the falex test can be done improperly, and manipulated to with great variance in results. extremely similar to the tests performed in the magazine.
would you put shampoo in your engine? According to this test, it could be the best oil ever made!
just take things with a grain of salt and realize that there's much more to oil than any one specific test can show. Used oil analysis using various oils is the only way to know....
mobil 1's response to tests of this type:
There are certain oils in the market today that use EP (extreme pressure) additives in their engine oil that are really designed for gear oils and not engine oils. Extreme pressure additives are typically not used in engine oils for a number of reasons but the most important is because they can cause engine corrosion over time. The rigs being used in these demonstrations are primarily designed for industrial applications like gear oils where extreme pressure is an important performance feature you need. These demonstration rigs have very little to do with modern engines and that is the reason that market leading oils in the industry perform poorly in these tests.Black 7M-GE 84 P-type Hardtop
