Oil analysis after 9400 miles

Thanks mac7 for your detailed reply. I was a bit sceptical about the test procedures myself and glad you put my mind at rest.
I'll continue using my Motul with confidence.

But is it any good? It seems from the article Mobil 1 did not fare too well. Wonder if the Mobil 1 ESP is any better
I use Motul Specific 504 00 5W30. I wonder how this would fare?

Motul Specific will produce a big wear scar. If it didn't, I'd be worried.

The test they use is entirely misleading - as they say, a little knowledge can be dangerous. Firstly it is not representative of any loading condition in the engine. Secondly the results are as expected and do not highlight any deficiencies in the decent oils (Motul, Helix, Fuchs, Mobil 1) but rather show they are superior. Lastly it is a very basic comparison of oil viscosity which was created in the 1930's before we developed an understanding of the science of lubrication.

The reason the obscure and cheaper oils produced much smaller wear scars is that they are thicker at room temperature (higher base oil viscosity). In fact high viscosity is the last thing you want in a cold engine. All the decent oils shown have lower viscosity at room temp as you'd expect of 0W and 5W rated oils. You'd get a similar test result from cooking oil, and I don't think most people would consider that for their GTI engine.

Of particular note is the Penrite oil, which they claim to be the best and based on its 5W60 rating seems to be suited to a huge temperature range. However it is a high viscosity oil (proven by the testing) not suited to low temperatures and only achieves its 5W rating because of viscosity modifiers. In use these break down relatively quickly, the oil will thicken and become more like a 15W50 within 1500 miles or so - good for the high temperatures and unsophisticated V8 engines in Australia, but not really suitable for turbo motors driven in Europe.

As a side note, the oil analysis in the original post found higher concentrations of iron in the oil. This provides evidence that wear does occur as components are run in - even with the 'modern engine tolerances' which many claim make running in irrelevant.

This is good stuff to read, very intresting thanks Mac

Thank you again for clearing that up I just posted it up and didnt think that that test was that accurate on engines.

Also like I said I did not break in my engine. I redline it pretty much all the time.

So what about an oil FILTER CHANGE @ 5k? Would that help?

Definitely with every oil change, as the filter will be new and clean, without any debris and does not cost the earth. Not to change would be pennywise pound foolish.

[Dawnskaybug]

No I meant change the filter at every  5k then the oil at 10k

Is it easy to do without a complete oil change?
If you can, then why not. But is it worth it?

[Dawnskaybug]

The filter takes 45 seconds to remove its on top of the engine and there is a check valve so you dont drip a drop of oil. you just have to top off whatever oil was in the filter.
The filter removes stuff from the oil and I have stuff in it..

Ok then. Go for it. Just shows how out of date I am!
Do you use Mobil 1 ESP?

[Dawnskaybug]

Yes I used Mobil 1 ESP. The test was with OEM Castrol.

I did an oil change today on my GTD, its not that simple anymore found it a bit fiddley TBH, its the filter where they put in the top part of the engine got remove pipe work & senser to get to it bit of nightmare to do!!
