Can you post your oil analysis results?

I just received mine back and few things don't seem right for only 9,563 miles on the odometer, and oil changed every 12 months:

Copper (average = 3) = 3 (my value)
Tin (average = 1) = 2 (my value)
Boron (average = 71) = 90 (my value)
Fuel % (average = <2.0%) = 2.8% (my value & 5% is critical)

My main concern is that the fuel dilution seems awfully high for such a low mileage engine....

{Note: I put 1,000 to 2,000 miles in between oil changes, so my vehicle has had 5 oil annual oil changes}

When you drive it, are the trips long enough to allow the oil temps to reach normal operating temps? This aids greatly in boiling off the fuel that naturally works its way into the engine oil.

Next to check is your Crank case Ventilation lines to make sure they are connected properly and not cracked/damaged.

You can also have your injectors tested with ISTA loaded on a laptop and enet cable if you are a DIY'er or take to dealer and request injector leak test in ISTA/E-sys as it could be a possible failing/sticky injector.

interesting you didn't go with the HX. I haven't done much reading, does anyone know the pros/cons on going +0.001"/0.025mm on the S63? Is there any data proof?

[Chilled]

Or the better question would have been, does anyone know what's a good spec for the S63?

Looking around and a few of the shops that have built the S63 to 1000whp+ all just hide and say proprietary. No brand, nothing.

The only thing I could find was a down under place, PPM. and their 5.0L kits. These run the ACL bearings.

sorry for not updating the thread for so long...

i already made 10k km on the rod bearings replacement and no issue at all.
meanwhile i made some huge upgrades. Pure turbos stage 2 turbos, jb4 with methanol injection, remap. And everything gone to a result of 920hp.

The car is driving wonderful and it's a true beast.
And for sure i recommend to change the oil every 5-6k. Better if you have an aggressive tune.

If you have any question, i'm here to answer them and help as much as i know

Wow, nice.

Well done sounds like a beast.
