oil change ? (Merged with previous thread)

This blackstone report is going to be meaningless because its the first oil change in this car and the wear numbers are going to be high regardless becuase its from the break-in oil. The TBN should be very very low as from the pics the oil looks to have oxidized and your viscosity will probably be on the 40wt side.

Meaningless in a sense that if the wear metals are high, for example if the value of iron in yours was 15 and his comes out to be 50, what are we to conclude from that??? If he changed his oil at 5,000 miles and if is driving style is much different than yours his iron levels at 5k might be 25. First UOA's on a new car are meaningless but they are important if you plan to get subsequent UOA so you can have a trending effect. He's just doing this to show off that he can go 10k and not worry about the car breaking. There will be no trending in his part.

The results are in! All is good! Blackstone thinks I can go even longer on my next oil change... So 10,000+ miles for the first oil change was just fine, and keep in mind, I REALLY drive my car hard... I don't let it warm up, I floor it all the time... So if you don't drive the car as hard, I'm sure longer would be possible, since the opposite logic always holds true...
I am thinking about going to 12,500 or 15,000 for my next oil change... Thoughts? (BTW, the shop used normal Castrol 5W-30 oil for my oil change)
Summary of results: TBN = 2.0, additive is left... Blackstone says my next oil change can go to 11,000 safely... Here are the details of the results:

See, I was right !!!
Seriously, even tho you still had moly and your metal reads were acceptable, your oil was very dark (dirty). I believe Castrol dino is the factory fill, so you're fine there. You shoud stick with 10k OCI and do your next change at 20k (if you still have your IS by then - LOL). . .

For the most part, your results look about like my 5K and 10K UOA numbers added together, which is great. The biggest difference is the amount of silicon. It seems that there is a ton of silicon inside the engine from manufacturing, which I would assume you would want to rinse out sooner than 10K miles. My silicon dropped from 288 at my 1st change to 75 at the second change (and 25 at the 3rd). Obviously, if you add my silicon numbers together, it will be more than yours, but I'm sure that is due to a difference in air filtration and environment.

Damn I'm good, now if I can only be this good in Vegas during Football season . . .

Cool. nice to know that its VERY safe for me if I change my oil at 5K miles.
Did you reset the oil change indicator at 5K? cuz it stays on and bugs the heck out of you if you dont change the oil... I had my 15K mile done at 15200 and that 200 extra miles was the worse! I hated seeing that red ! and the Maintenance required on my instrument cluster
