and it's not so good. Here's the report, iron is high at 60 ppm which is on the lower high
Iron Generally results from ring, bore, cam, tappet or crankshaft wear. If the concentration
quickly reaches 50 ppm inspect to determine the cause. Permissible maximum is about 100
ppm.
That's the oil from 2023 when I bought the car. Oil was end of life (0% in computer).
Valvoline MST C3 5W30 full synthetic (Dexos 2)
What are our stock cams made of? Iron with no coating?
I'm waiting for my BTR parts to arrive: cam, gaskets, springs, DOD delete kit so that's on point. I hope my crankshaft is fine tho
Do you mean the Mobil1 ? As far as any oil is Dexos approved it doesn't matter does it?
I changed oil yesterday with iirc Champion Full Synth 5w30 Dexos and will run that for 500 miles, then flush again and get the new recommanded Mobil Supercar 0w40 Dexos3/R if I can source it in Europe
Yes, Mobil 1 0W-40. The recommended oil by GM and Chevrolet. Good job. Also, if you can find a non Mobil 1 Dexos approved 0W040 in Europe, I would guess this would be ok.
Have you floated this question to BTR and see what they have to say? Hopefully it is one of the things you are replacing. As to the oil, maybe it would be best to give them a list of oils you can get and have them make a selection?
I've heard of high iron levels from having rust inside the engine (cylinders?) if the car was stored too long. Is that possible in your case?
Before doing the work and expense of your mods, I'd do an oil change first and have it analyzed after maybe 2k miles to see what's happening.

Yes car has been sitting 12+ month in cold garage with some humidity. Our blocks are iron right? I'll have a talk with the lab specifying that. Maybe that will impact the range of acceptable values for iron
The parts are ordered tho, I just wanted to physically delete the damn DOD anyway. I'll analyze oil again next change
It would appear GM is conservative on their OLM so at 0% the oil is most likely still good, but that's where an oil test would have to come in. Prime example. I changed my oil in November and when I pulled it out of storage in March it was down to 70-80% without being driven. The oil was fresh but the monitor is counting down the months as it will go to 0% after 12 months regardless.
Here's a good example explaining the system. Sounds like GMs is the best as it's more conservative.
Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
Today a lab analyzed my engine oil
