Broke a 70mpg trip last week. Also got my oil analysis back from Blackstone.

Thanks for the report!
Some information, if it's helpful:
I swapped the 1.0L engine in "Gaptooth" for a Japanese market equivalent of a Honda K24A2 (from the 04-08 Acura TSX). The engine looked good inside and was advertised as low miles, but the actual miles are unknown. I'm unsure where the lead comes from in this engine but it could well be crank bearings.
The oil used was Mobil 1 0w30 (standard) and the engine was run quite hard over a 7500 mile interval, with a lot of bouncing off the rev limiter and WOT pulls. It also has very tall gearing, so there's a lot of very low RPM, high load operation.
The numbers look pretty good to me, but given the information I've provided, do you have any insights or cautions for me? I replaced the oil with Mobile 1 0w20 Extended Protection, and will be sending in a sample of that at the next 7500 interval.

Interesting to me is that a 2.4L engine, driven far harder and with way more moving parts has lower wear indicators. There's also more oil in the pan, but liter of displacement to liter of oil, the K24 has less.
