UOA's - Used Oil Reports - Let's See 'Em

Engine oil reports from my 2012 Speed3, stock engine:





(note: the Supertech seemed to change formulation slightly and around the same time the "Dexos" certification labeling appeared. I have labeled the one sample accordingly)

Transmission oil reports from my 2012 Speed3:



Engine oil reports from my 2007 Speed3 with Wiseco OTS pistons (note: the engine was rebuilt around 60k miles):



Currently the 2007 has the Supertech 5W-30 full synthetic Dexos in it and next oil change I am going to try the Mobil1 0W-40 "European" car type gas engine oil.

 

I'm just about to send my pezoil platinum out that I cooked at a track day (300+ oil temps) I will post the results when I get them back

Great idea! Expect lots once I get my engine fired.

 

Brad Penn 10w40
Manley 2618 Pistons and H-Beam rods.
Built motor had 57,800 miles at time of analysis
Oil had 2800 miles. Tuning for 6th port (I switched from meth injection over the winter) was done on this OCI, plus my normal driving. So atleast 2 dozen, if not more WOT pulls.

 

The last one I did before building the motor. Working the stock block pretty damn hard, E85 mix, methanol. Mobil 1 Extended (15K mile oil). Details are in the report:

 

First report is the last one before I spun the bearing on cylinder 4 on my way to dragon camp. The second is from the oil after the spun bearing. I was running Rotella from the first day I picked it up brand new. 72,000 miles

Stockblock. TMIC, TBE, E33, SRI+TIP are the power mods. 85k on the odo.

Little update on how my engine is wearing. The motor probably had about 12k on it at the time I pulled the most recent sample. It burns oil like a mofo (I've been told Wiseco has a rep for this due to crappy OCR design), but static compression has gone up since I bought it 5-10 psi across the board and it continues to produce excellent oil reports and make great power. I'm not sure why the oil keeps shearing down other than I'm using the oil for autocross and with ECT's hitting 230+ at times, it's possible the oil's getting a little overheated.

So far seems like the Mobil1 "European" 0W-40 is in the lead as copper is the lowest in that report indicating the rod bearings are being well protected. I'll probably continue using this oil for the rest of the motor's life.

 

I got the kit, changing oil Wednesday and will send it off. Never had it done.

 

Not sure what to think of mine yet....

 

Craigslist gonna be like "runs great, fresh oil change."
