Yeah, iron is high but the copper is even higher. Basically it is still the wear-in materials since this looks like only the second oil change. Letting a vehicle sit for months unused with oil that has been run isn't the best since moisture still gets into the engine and cause issues. The older used oil has a higher acid build up in it so that adds to wear when it sits and then gets started up. No TBN to report so we can't say how much additive pack was left in the oil. I have always been a believer in changing out the oil in anything that is going to sit for a few months at a time. There are oils on the market now that are made for classic vehicles that have additive packs to help with moisture and this tailored oil helps keep things in condition while the vehicle sits by keeping a protective layer on all internal parts that normally would go unprotected with normal oil.
Mobil 1 has always shown high iron levels on LS engines, just the nature of the oil. You can view a ton of LS used oil analysis listed on bitog web site where Mobil 1 has been used and see the trend on iron in that respect. Nothing major but just higher than when other brand oil has been used.
