    It has nothing to do with how an engine operates, I know that test looks impressive but it is all about selling oils. Apparently bleach is better than oil in that test. We get back multiple race engines for freshen up after a season of torture in the harshest of enviroments [8400+rpm lap after lap, some drag race 9300+]and we see the results of the oils used. with VR1 the bearings look brand new, you can even see the dial bore gauge marks from when the clearance was checked. Those results and the lack of any wear in the engine are all we need to verify the oil we use is good. Now if you want to talk about what oils we have tried and the results of that, I am open to discussion. I will not name brands but you will know what I mean.

    AED,
    Believe what you like.

    The Timken bearing load test is a test that tests one facet of an engine oil: the oil's load bearing capacity. It does not test things like the temp at which the oil breaks down, it's ability to control sludge etc.

    Have you had a look at the link/video I posted? In the old Aussie test why would a lower grade oil from one manafacturer outperform their higher grade oil. These are massive companies with all the resources and technology.
    I think its hard to ignore the real world evidence that has been given in this thread.

    I’ve never trusted/looked at Valvoline. Maybe it’s because of John Laws. Know what I mean. Might have to reassess the situation. I used to always run Fuchs, but the 355 has penrite hpr30 10 tenths. Seems good at the moment.

    Here is a link to a comprehensive oil test, over 200 oils from memory. VR1 did very well. The pressure test is used. Also, the zinc myth gets a had grenade...

    The valvoline synthetics did well too. Great read. Its long though lol. All the big names were up there Mobil, Castrol, Pennzoil, Amsoil along with the expensive exotics. There really is no need to go above 40w with the quality of base oils now.

    I agree 100% with that, with heavy oils the filter by pass is open all the time and unfiltered oil is passed through the engine, this is why old holden V8 mains look so bad when you pull them down.
    If you block the by pass and use a 20-60 oil you run the risk of collapsing the oil filter and blocking supply, I remember someone on here had that problem before. Also there is the side benifit of making more power with the thinner oil so, its a win win. The engine will love you for it.

    with a blocked bypass and 15w40 oil even cold the pressure goes high & have collapsed filters. pretty much have to idle it until oil is warm which takes longer than the coolant to get upto temp. 80psi at less than 2K rpm is asking for problems

    I remember Street Commodore doing a timken test of a number of oils. From memory royal purple was the only one that passed.
    Naturally all the other oil companies were not impressed with their testing and Street Commodore had to back off. On the basis
    of their testing I started using royal purple. When our dollar went down the price went up, when it went back the price remained
    the same so I stopped using it. Also their claim of a 5 rwkw power increase certainly didn't work with my car.
    I also read the oil report mentioned earlier, certainly worth reading, it would have been a better read if it wasn't so long.
    Having said that a layman like myself certainly learned a lot.

    I dont think even Gary Halbert from north of jewfish creek could have written a better sales page for amsoil or that additive if he tried. But it does resemble his sales letter technique. He used to charge $40k for a sales page like that.. regardless im keen to switch to a oil higher up the list from now on with my stupid rubbed lobes

    Should have read his water filter sales page, cant remember if he was a retired municiple underground water pipe repairer or an engineer in that one either... old man used to say believe none of what ya hear boy and half of what ya see and you will be ok.

    Keith,
    In that SC test, first place was a tie between Royal Purple & Penrite.
