To add to this with my anecdotal evidence, I started getting a P0420 in my Subaru STI with around 70K miles, I tried clearing it and using other fuel adds without succcess over 5k miles. It's older than 10 years so no warranty left. I was starting to get power loss and hesitation as well. I...

Oil Temp 220F-230F, defi gauge. Pressures were just fine as well. If there's anything I'm worried about it's the cooling. Water temp got to the 3rd long tick mark, which is just a bit too hot for the system but stabilized. This was towards the end of just a 10min session. If there's anything...

If it was a coolant leak, you see it under glycol, which is 0. The engine was given a proper beat down so I would expect higher iron content. Sorta still wearing in. The engine mount broke along with the dogbone, so it was clunking for bit . Maybe loosened up some particles HA!

2549mi, Track Day and at least 100 AutoX runs. ("Spirited Driving") Pennzoil Ultra,not PUP Filled with Pennzoil Ultra again. OEM Oil Filter Replaced Air Filter before the 2549mi run. 100% Stock Car The previous 1319 result was just a sample pumped through the dipstick tube and was not...

Originally Posted By: Donald OP - can you verify if there is an engine oil cooler? Maybe because of the turbo there is one? The high copper is not good. Could be break-in but not sure how much break-in there is in a bearing vs rings or cylinder wall. The lack of lead is also interesting. I am...

Originally Posted By: Eddie I see you added 1/2 quart of oil on this OCI that wasn't needed before. Have you been beating the snot out of it? I was half way down the dipstick reading last oil interval. (In between the L and F) I just didn't have oil to add it back to F which is fine. STi takes...

Pennzoil Ultra 5w-30 2013 STi, Stock Mileage is slightly incorrect on the sheet. Should be 3131. [/URL] Going to give it another short OCI, same oil. Other numbers are on par

Originally Posted By: fdcg27 Why not do a couple of 5K runs of Ultra and then do a UOA? This is obviously an engine still wearing in, so you'd expect high wear metals levels, although your second UOA shows much lower iron and aluminum than your first. For science and because race-car! Curiosity...
