Some notes:
Engine is a Isuzu 4XE1-MT turbo I4 (Lotus modified version of the Isuzu Impulse RS)
An additional 2 qts of oil was added due to the replacement of the timing belt and assorted seals midway through the oil change interval.
Lotus originally recommended using a fully synthetic 10w30 with this engine, but now recommends Mobil 1 0w40, the Mobil 1 is now in the car.
Purchased the car at the beginning of the oil use. Not sure what the previous owner used.
This is what Blackstone has to say:

We haven't seen a lot of these Isuzu engines before, so our average file isn't as solid as it
might be. We'll know more about your engine as trends develop, but at the present time, we don't see
anything too out of line. Aluminum and iron are a bit higher than average, but your oil run was also twice as
long, so a little extra metal isn't necessarily a bad thing. Other metals look great. The viscosity was just a
touch low, but that shouldn't give you any trouble. The 0.8% fuel isn't a serious concern either. Overall, this
is a nice report. Resample in 5K for another look.
