Unknown Jiffy Lube filter.
3000 miles on RedLine HP 5W30 following JL's engine clean & flush service performed by previous owner prior to sale.
Loosened soot residue was dry and flakey. Had it occurred to me, I would have checked on and likely changed the filter after 1000 miles and every 1000 after until the oil reached 5000 miles.
Replaced with Fram XG8481 and Valvoline R&P 5W30.
