X15 down on fuel economy recently?

[marek4792]

Not much of an update, power is back mpg is so so. Soot level seems to be stabilizing after climbing to the moon a couple times and a few rolling regens later..

But an issue I didn't mention earlier but I thought I'd pass on, so I had noticed an oil pressure drop-off at lower end of spec at 1500rpm warm. Idle at 700rpm was 26psi warm. Decided to have new rods and mains rolled in and oil pump put in based on a recommendation from a friend with x15 who had done his the previous week at 570k miles mines at 533k miles. Went from low 30's psi at 1500 rpm warm to 40ish psi at 1500rpm warm, big difference! Oil sample pre repair came back clean. Had a picture of the worst main bearing smooth when scraping with fingernail, but rods looked clean all across, but if you're above 500k miles and noticed a pressure drop off that seems to be no apparent reason. Oil pump sounds like a very likely culprit in my situation.
