First time doing a UOA, as I got curious what happens when oil sits in a crankcase for 5+ years in a low mileage car.
Quick facts-
- Maserati 3.0L twin turbo 90° V6 (officially the "Ferrari F160" engine, as it was hand built by Ferrari in Modena).
- oil sat almost 6 years in crankcase. this was the car's first oil change. stock fill Shell Helix Racing 10W-60.
- car stored in a climate controlled garage.
- 2,300 total miles. bought new, and never "topped off" with any oil.
- completely babied the car, followed proper break in procedures (varied RPMs, driven gently while cold, never exceeded 5k RPM)
- no short trips, I made sure to drive it at least 50 miles every time I took it out. no lengthy idling either.
Is the high copper content (8x the average) typical with a new engine? Ditto with silicone (possibly due to sealants during manufacture?).
Because the lead + iron is normal (thus not a sign of premature wear?), perhaps it's (high copper content) the oil coolers? or something else?
I'm a technical car guy (love sketching out A-arm / wishbone suspension geometry designs when bored), but not really an expert on UOAs.
Thanks in advance for everyone's input.
