Just to close off this post with the cause of my oil consumption issues. Vertical scoring and glazing at the bottom of cylinder 6. I'm not happy, but at least I finally found something. I'll pull it and get it apart asap. Hopefully I don't need to go one size up in piston. -

I finally got around to purchasing an actual articulating borescope. Great tool to have, I've been very impressed vs my old regular inspection camera. With that being said, sadly I finally found the cause for my oil consumption. I always had the feeling something wasn't right but compression and leak down tests were always perfect and I had already inspected the cylinders. This time i dropped each cylinder to its absolute lowest point and with the better quality camera I found this... Bottom of cylinder 6. Scoring looks deep and I'm presuming oil getting by caused the glazing. I already spoke with my assembler, and will be dropping it off as soon as I can pull the motor and get it apart. I'm just hoping it's not deep enough to require boring out from 86.5 ->87mm. Pistons aren't cheap. -
I think it's the same. It all comes from the same shithole refinieries in SE Asia. -

I was referring to the final octane level achieved once 10% ratio of ethanol is added. -
