Got my first oil report back from Blackstone.
I got the car at 1800 miles from a dealer who said they did an oil change.

So, assuming they really did... I changed the oil at 2300mi so 500 miles or so on this sample. In those 500 miles I saw probably half street and half track.

I am sending in my next one today after another 500 miles of mostly track.

It is noted in the report that the iron number is high. I called them to inquire why. The average is 38, mine says 20, why is that high?

The answer is because the "universal averages" are for oil that has seen 2300-3300 miles. Mine was only 500.

So, an iron count of "20" is high for 500 miles, although they feel the car is still "breaking in" at 2300 miles.

Comments appreciated. I'll know a lot more after I send this next sample in but any feedback is good.

The iron count of 20 is highlighted. All the additive numbers down near the bottom are fine they say and can vary because people use different oils.

I am now really wondering if the selling dealer did an oil change if my oil doesn't resemble what most would look like at a 500 mile initial interval...

I doubt that the dealer did a change, but not because of the oil report, just because dealers tend not to do anything that is not absolutely necessary. At that mileage, the engine is certainly still breaking in, so I wouldn't get too concerned about any values in the report unless something is way out of spec.

Anyone else have a Blackstone report with high iron counts?
What about all you valve issue guys?
I don't know what worn valve guides would show in a report.

I do believe my high iron is because the selling dealer never did the oil change as asked when I bought her with 1800mi on the odo.

If they had not changed the oil, this report would look pretty normal for a first change at at 2300 miles.

Seeing that they "say" they did it, and I did call them yesterday to verify, I still will need to see another report to tell if anything is going on.

here is my report i copied & pasted, excuse the format . this was the first oil change on my brand new '13 my numbers are higher than yours considering the fact of miles between our samples (5323 vs 500) a lot of the initial break in metals were removed from the original oil in your engine so I would tend to believe they changed the oil, I should
See a similar # as yours next time around (although I'm not changing at 500 more like 5-6000 mi.
Hope this compare helped
Rob.

Here's my last Blackstone report info.

https://www.corvetteforum.com/forums...and-sport.html

My iron was "18", after 7324 miles, but don't really know what that means as a comparison for yours, so be careful as you compare numbers between the reports.

My last sample had high iron after the heads were replaced.







I just sent in my 5000 mi resample, and it was received by Blackstone this am. I will post those results when I get them.

Rob,
I'm no expert but your iron and copper numbers look very high to me based upon the averages, albeit those being for typical oil changes on average at 3300mi.
My iron was high at 20 for oil that had supposedly only 500 miles on it.
That is why myself and my new dealer agree that in all likelihood the previous dealer did not change the oil at 1800 miles.
If he had, my iron numbers should have been way lower on oil with only 500 miles on it.
What oil do you run and what comments did Blackstone have?

12zo

Erik,
Thanks. Your sample is interesting too.
I see you had one sample with only 450 miles on the oil a while ago. That sample had similar iron to mine at 500 miles.
The next one seems normal.
I'm wondering what prompted a change with 450 miles and curious as to how we both have similar iron in those.

I just ordered the kit!

That report looks great.

Yes a bit of iron is due to rings scuffing and breaking in cylinder finish. Engine is still new.

Cars that dont get driven often tend to exibit slightly higher iron as the cylinders tend to get a slight flash of rust if sitting for long periods expecially in humid areas.

Roadcourse use, may want to look at a better oil. Looks like you are using M1 5w30?

The sample with 450 miles on it, was taken as a baseline shortly after I got the car.

The heads were replaced in April 2013 at 36,000 miles, so the last sample was to see what was going on after the heads were replaced. My latest sample should be tested today has about 5000 miles on the oil, and right at 46,500 on the vehicle. I'll post that as soon as I get it.

Rob 99

In your case you need to set your own history with changing and testing cause your not exactly sure what happened previously and don't have the luxury of the initial baseline, then you'll have a pattern you can trust.

As for my numbers I'm not to concerned now, if they don't drop and stay high then I'll have to worry about it then. My previous vette '07 &'04 had similar #'s at initial testing.
Also this oil was factory fill dexos and was in the engine for about a year & half 5323 miles(I know I don't drive it enuff ) as for Blackstone's comments here they are;

"ROB: When it comes to brand new engines, a lot of metal and silicon in the first sample isn't enough to make us cringe. The high metals are from new parts wearing in and the silicon is from harmless silicone sealers and sand casted parts. This engine initially makes a lot of metal, but after a few oil changes, this stuff should wash out and your samples should look a lot like universal averages (or better), which show typical wear for this type of GM engine after about 4,600 miles of oil use. No issues were found with the oil's physical properties. Check back to monitor progress.''

Just got my most recent results from Blackstone.
