OIL Fill Level - 2008 R56

[Rob Mc]

Race shop filled oil about 1/4 inch over max and advised that .25 quart over max is way to go with mods I have.  Never heard anything good about going past max fill line.  Thoughts please.

What mod are they saying they are accounting for.

Sorry I should have said it better.  They said it was what they recommended for my car.  Just an assumption on my part.   I have water meth and tune by Fred at Tech Tune Crofton. Complete mods are:

 

Manual Trans - Ringer Racing Clutch Stage 3 and Flywheel

Milltek Performance downpipe High Flow Cat

-        vibrant j spacer with their smallest size jetting

Wagner intercooler

Borla Sport Exhaust

K&N Cold Air Intake

ecu tune SPS Tech Tune Crofton 

-        ( Stock, 18, 20 and 21.4 psi) ( stages set by plug in controller stored in glove box)

Brisk Spark plugs gapped at .025 

Snow Performance Water Meth injection (controller on dash to left of wheel – washer fluid tank converted to Boost Juice reservoir)

BC Racing coil overs

Torques solutions engine mount.

Zimmerman drilled rotors (front)

The only reason I can think that they are slightly overfilling is to account for blow by. These engines have blow by normally, but will a turn with increased boost this could increase. 

 

As you have no internal mods or that would change the oil need or representation of fill level. 

 

The right way to address this would be to check your oil every time you fill up with gas and top off with oil to replace any loss.

I have 150k miles on the car with a complete new engine at 75k when the orginal owner lost his timing chain/tensioner.

I only put about 4,000 miles a year and use full synthetic.  No significat blow by.  typically only down to 3/4 to 1/2 of fill line at time of oil change.  Race shop was highly recommend on this forum and they love cars, I see a lot of minis in for service - that said I am inclined to drain a bit out.  Agree?   And thank you for the help!
