got my 2nd uoa in with diesel 15w/40, changed at 2K
my wear metals are better (new engine )
It all looks better (and I will post it tonight from home) EXCEPT
I now have a 2.5% fuel percentage and thats not good. It affected my viscosity and flash points. Now for those of you who are not aware, I am supercharged with larger injectors and a water meth injection system that I turn on only in boost (not often).
I am presently scratching my head--may have to go to a 20w/50 all the time. I do keep my oil temps up now with the coolers blocked.
Maybe i need a better oil pan vacuum system?

I didn't send my old oil in - but my first oil change was done yesterday.
We took a small sample due to me having a brand new engine and we ran it under a 10x scope and an electromagnet.... there was no discernible metal in the oil; thank you ceramic seals!!!!!

Shhhhhh but I use old oil to help me check for exhaust leaks.... LOL redneck I know.
The vis looked fine; but it has been cold here and I haven't driven the **** out of it - no fuel smell really either.
Then again I was using like $100 bucks worth of high end motor oil as break in oil... hahaha

Hell yeah! We have the statewide meet coming up soon so 300 miles of curves and switchbacks should do it I also plan to do a impromptu run of the route prior to that.

First oil change results
Here is my first report (is there a better way to include the image?).
It's better than I would have imagined, considering the interval, first oil change, etc. The make-up oil was probably closer to 2 quarts, as I bought it as a factory rep car with 1000 miles on it and the dealer had topped it off before I took it.

how the heck did you have a cst of over 8 with a 5w/20 oil?
I am beginning to believe the devil invented uoa's
Your's sure looks good
Just for the hell of it --i will changing out my diesel oil for a track oil for a w/e at Road Atlanta march 12/14.
I will do a uoa post weekend on that change. I will be going with a 20w/50 oil for track--probably castrol gtx.Maybe Redline 15w/50 --dont know yet.

Here you go Pete. It looks really good for 5,500 miles (a lot better than the GC 0W-30 i had at 1500 miles). I was just talking to grungepup this morning about doing a UOA of his 5W-20 since his car is dealer serviced every 3k. Thanks for posting a UOA of 5W-20.

Here's mine with RotellaT 10W30 - none added during the 2000 mile oci. It was very clean before this oil went in since I have changed it 4 times in 7,000 miles. (I just bought the car in Oct, and have no proof of oil changes beyond the factory recommended.
Does this phorphorus and zinc look good (from the perspective of people who don't like the newer ILSAC std)? 797 and 954
1.8% gas; 330 flashpoint
Who can help me post this .rtf? I click the manage attachement button and it just says error on page.

As for the rest, I expected worse since I don't know how the car was handled for the 1000 miles before I bought it. I imagined a lot of cold starts to move it around, etc., but I guess it wasn't too bad. I have 5w30 GTX in it for winter, and probably will go to 10W40 for summer. Future UOAs should be interesting...

I don't see anything out of the ordinary. A viscosity of 8 cSt is about average for a 20W oil at 212*F. It may be a little higher or lower. He's at 8.3 which is right where it should be. Here's a chart showing expected ranges for various oil weights.
