Well I will hopefully be performing another oil change here shortly. Still on my first batch of Eneos 0w50 at 5k miles. Will be changing the oil with Eneos again, and running it for another 6-7k miles before sending off samples to Blackstone. I did not want to send them a slight mixture of my previous oil with the Eneos.

I get 5 L of LiquiMoly 10w60 for $40, so it's a very affordable change.
Here is the re-uploaded report.

I've read a previous article on MOTUL V300 with Snogard & Lscman but it's dated 2007 so I prefer to post this test here :

Comparatif huiles moteur, Royal Purple, Motul, Castrol? - Renox France

It's in french but you can use Google translate to understand the main ideas...

MOTUL 300V 15w50 isn't good, even for short term protection (compared to other tested), as you can see with the Timken test.

it's not graph or oil analysis report but I though you'd find this interesting.

Also, below is the link of a oil analysis :


Look at the right column, it's 10 000kms oil test with the product Ecotec T2S. Last line is wear particule indice.

you can see the same kind of resistance test with this product below :

Maybe the kind of product used in RP HPS oil to get its extreme protection.

Personnaly, I'm using this product in all my cars including the E39 M5 for engine & gearbox. (Yes, it's not OEM, but !)

Here's my current oil analysis on 5K miles on AMSOIL Premium Protection 20W-50. Sample #1 in report is the baseline on TWS 10W-60 oil change done by PO. I bought my car in Nov 2014 and have been working steadily on it. Applicable items have been fuel filter, spark plugs, all four O2 sensors; just before sample #2 drawn I replaced all CPS and VANOS solenoid seals.

My current opinion is that this oil is providing excellent protection. Engine runs fine but I need to get it out more on longer, harder drives - the last time I did the fuel mileage was much better than the 16-17mpg I get in "around town" driving. I have yet to address changing the thermostat and MAFs.

Liqui Moly 10w60. No idea how many miles were on it or how much oil was added; it was the oil that came in the car when I bought it. Car has 146k miles, MY2000:
WILLIAM: Thanks for the notes. We didn't find any extra bearing wear in this sample. In fact, lead is below
average at 1 ppm, so the bearings in this S62 appear to be getting along well. You mentioned some oil
consumption too, but if the engine only used a quart over 5,000 miles that sounds pretty normal. Something
like a quart per 1,000 miles would be more worrisome, and we'd just keep an eye on how much oil the
engine is losing. The flashpoint being above the expected value shows no measurable amount of fuel. The TBN of 9.7 is well above our 1.0 lower limit.

ZINC 1035

SUS VISCOSITY @ 210*F 87.1
cSt Viscosity @ 100*C 17.27
Flashpoint in *F 405
Fuel % <0.5
Antifreeze % 0.0
Water % 0.0
Insolubles 0.2
TBN 9.7

Red Face Latest LiquiMoly 10w60 analysis

From Blackstone:
If you did something differently on this fill compared to last time, keep it up - nickel and silicon both
dropped out of cautionary ranges, and the small amount of fuel we'd been seeing for the last four years has
cleared up. With the absence of highlights, this M5 has earned its first perfect report, and we see no issues
with how this engine's operating. Besides having no fuel, there was no other measurable contamination,
either, and viscosity was fine for 10W/60 grade oil. Air and oil filtration both look great. Good-looking BMW
at just under 150,000 total miles.
