LOL...Well, my engine certainly isn't dirty, and I hope it isn't broken. Anytime you modify a car like I did you can expect more wear. The rev limiter in my car is a fuel cutoff, but the ignition still fires and the car is under full boost, which causes detonation. I'm sure that's why the iron levels are higher than usual. Whether or not the elevated levels of potassium and sodium are because of coolant remains to be seen. I have 2 quarts of Redline left. What I might do is switch back to Mobil 1 again in 3500 miles and then do another analysis. Mobil seems to have gotten their act together and I was thinking about it anyway. I was at Wal Mart and saw 5 quart containers of Mobil 1 for $18 about a month ago. By the way, I only pay $80.89 after sales tax for a 12 quart case of Redline from a local place, so that's not much more than what most places sell Mobil 1 for.
Patman, the reason they put the question mark in the anti-freeze column is because of the elevated potassium and sodium levels. Here are their comments:
"We've seen many samples of Red Line oil where potassium and sodium show up. These elements in your sample are probably from the oil itself but it is worth mentioning that they can also come from anti-freeze in the oil. We are seeing no other signs of anti-freeze. This oil was in normal physical condition for a 10W/30 and appears to be getting the job done in your engine. Iron went higher this time (compare wear to universal average levels for this type engine) and is above agerage, but it may be related to your longer oil use. Stay at 3,500 miles next sample."
Bror, I hope you're wrong, but it's possible. When the kit was put in my car, the 2 geniuses that installed it didn't bleed the air out of the coolant. With the A/C on, the temps got way too high when at a stop a few times. I remember one time when I pulled in the driveway to let the car idle (cools down the turbo) and forgot to turn off the A/C. The temps started climing pretty fast, I panicked and shut the car off. I don't think that was a good idea and may have warped the head slightly, I don't know. Since I bled the air out, everything is fine. Even though I see what looks like oil residue in my coolant overflow, I've done compression tests, leak down tests, and even NAPA's leak tester and found nothing wrong. What looks like oil residue might also be from Water Wetter I've been told.
Thanks for all the comments, I appreciate it!
