2013 Golf R - Motul X-Max 0w-40 -

[mkosem]

I just got back the next sample from my Golf R. This car is set up with an APR Stage III kit with runner flaps deleted and an additional low pressure fuel system upgrade. This setup is supposed to be good for ~450hp at the crank. Still not looking terribly awesome, but iron is tracking closer to where my FSI engined GTI eventually settled. I'm not loving that blip on the lead. It's otherwise as it was last interval. I replaced it with RedLine 0w-40 this time.

The oils here are:
Motul X-Max 0-w40
Motul X-Max 0-w40
Motul Specific 505.01
Motul Specific 505.01

Blackstone's comments were:
MATT: There's a little fuel in this sample (again), the viscosity is a little low (again) and iron is just a bit elevated compared to averages (again). It's not that we love the word "again" it's just that we're kind of glad to see that the status quo isn't changing much from sample to sample. Maybe less fuel, iron, and a normal viscosity reading would be nice, but with nothing changing significantly from sample to sample it's hard to complain too much. Iron did improve just a little, so we didn't mark it. Overall, no real changes here, and that's okay because nothing needs changing

Does the car have lead bearings?

How much WOT does it see? You've almost doubled the factory horsepower rating, expect some accelerated wear.

Dunno. Blackstone's universal averages show 2ppm for this engine, so maybe it isn't unexpected. The big 2.0T FSI UOA thread shows lots of samples with similar pb numbers: http://www.bobistheoilguy.com/forums/ubbthreads.php/topics/1433235/1

I see some non-zero lead numbers here too, but on lower mileage motors: http://forums.vwvortex.com/showthread.php?5812687-The-Blackstone-oil-analysis-thread

Might be something to watch. Too early to call it a trend based on those others I'm assuming.

Quite a bit. Things seem pretty OK so far, all things considered. These wear numbers aren't too far off of what others are sharing from their reports on stock cars, but my intervals are intentionally pretty short.

The fuel dilution and viscosity don't seem as bad as the summary seems to be implying to me. I know I had one over 3% on my GTI once. Lead seems to be right where it should be too.

We'll see how the RedLine stuff does in a few months. Warmer weather should help too.

What is APR's recommendation? You are extracting a lot of power out of the motor, and the fuel is accelerating the break down of the oil. 10cst is awfully light for a 40wt oil, especially when you are boosted.

 

[mkosem]

Their recommendations are for Motul Specific (first two samples), X-Cess (not as good as X-Max), and 300v. 300v is probably good, but I'm not sure how well it scales in mileage.
