Wanted to update the post since I drove the car from Charlotte, NC to Tallahasee, FL to take my son to FSU Football camp. Just finished his freshman year of high school and was registered at the camp 6'-2-3/4" at 201 lbs. He had a great time and it was an opportunity for me to see how the motor would perform. Can't say I didn't get into boost, but with my passing under boost a lot I got ~23.5mpg on the drive down.
As documented I broke in the motor with Valvoline VR1 10W-30 (racing oil) and had no measurable oil consumption. After ~450miles I switched to the Mobile 1 0W-40 FS, but didn't put many miles on it before the TOB took a dump. Before driving to Tallahassee I added a little bit of oil to make sure it was exactly in the middle of the top notch. Well, on the trip down, which is ~493miles the engine consumed some oil and was showing just above the bottom notch. Needless to say this had me slightly concerned and not what I saw during break in. The car doesn't smoke other than lightly black upon initial boost hit with no signs of oil in the pipes or oil smell, but my catch can breather does smoke. However, catch can is more or less completely dry.
I went to NAPA in Tallahassee and purchased a case of Valvoline VR1 20W-50 (racing oil) and a new Napa Gold filter and had it changed at the local Jiffy Lube for $29. The mark on the dipstick last night after parking before my trip home was exactly in the middle of the V of the top notch. After the ~493mile return trip the dipstick was EXACTLY at the same place as when I left Tallahassee. Simply put, the car did not consume any oil that I could measure on the dipstick after 500 miles using Valvoline VR1 20W-50 Racing Oil.
The Mobile 1 0W-40 FS has great test data, but too damn thin for this motor. Not sure where the heck it was going, but sticking with the Valvoline VR1 Racing Oil going forward.

No problem, just sharing my experience. ZMax is having an open Test-n-Tune tomorrow so I will take the car to drag strip to see what it will do. I have only launched the car 2-3 times on the street in the 13 years I owned the car so unsure if I will try to launch it tomorrow. Really just interested to see what kind of MPH the car will see, which I hope to be in the 134-136 range. This is also the 1st time I have taken the EVO to the track so don't know what to expect. Supposed to be 67F by 9pm so it should make for some good weather for a track outing. My last outing was with the GTR after the Xona Green turbo upgrade (~706@wheels on Shell 93 pump gas) and the car went 10.24@138 stock engine and trans.

Like I said, I've only launched the car a few times since owning it and it definitely showed last night. Won't make excuses for the performance in terms of ET, but I am happy with how the engine performed. For safety I added 8 gallons of race gas and ramped in 3 degrees more timing from 6500 to 8000rpm so 12 total at the top.
First pass I slipped the **** out of the clutch, but atleast the car did not bog. Never taken the car to the track and quickly realized the gearing sucks so I was bouncing off the 8500rpm Rev Limiter in 4th so I let off well before the traps. For some reason AFR's were steady at 11.0:1 so probably having something to do with the race gas. I actually feel good about this pass because I watched a ZR1 run ~11.5@125.
Next pass I leaned out the fuel 4% and raised the rev limiter to 9,000rpm. AFR on this was was ~11.3:1 to 11.4:1 so much better. I tried to slip the clutch for a second and then let it rip, but rpm was too low and the car fell on its face. I also think I have an area of the VE Table that needs to be tweaked because AFR's went lean for a second so I just sat there waiting for the damn thing to make boost. Car pulled real strong and I was through the traps ~8900rpm or so, but didn't hit the rev limiter.
Final pass I leaned out AFR another 1% and again tried to slip then dump the clutch, but same results. Car fell on its face, went lean and then had to build boost again. The car pulls real strong once it gets going and again went through the traps just shy of 9000rpm.
I don't think I will take it back to the track again only because this car is my daily driver and I need it in one piece. Launching my GTR at 3200rpm and 0psi cutting 1.6 60ft is much easier than launching the EVO. I would likely need to setup the two step and get the RPM's up to ~6K in order to launch the car, but just don't feel like risking it breaking a diff or an axle. Oh well!

Just a little update. Car is running well with no complaints, but started to smell burning oil so I put the car on the lift. Definitely oil coming from the turbo return line drain, but the line was soaked externally from top to bottom. The hose was purchased from a local hydraulics shop and they said it was rated for oil at high temp despite it saying "Gasoline" on the outside. I was originally going to just run a short piece between the hardlines, but the hose was flexible enough that I just ran it in between the turbo and oil pan instead of mostly hard line. My buddy also warned me the long tube headers can more around after being heated so I wanted the ability to absorb the movement. I had just a 2" piece of straight tubing welded to each of the flanges, but I don't think it was sufficient for sealing. When I removed the tube it had hardened at the ends so I bet it was just blowing oil past the clamps.
I ordered a pair of 3/4" barb weld on fittings and replaced the straight tube I had welded to each of the flanges.
And installed...
I ordered some hose that is rated for high temperature engine oil so it should arrive Wednesday. Fragola Performance Systems Series 8000 Push-Lite Race Hose (803012) is -12 hose rated for oil at 300F.

Nice!
I’ve had bare oil return hoses get brittle and crack when they’re near a bare DP.
The DP is now wrapped and I treat oil return hoses as a replacement item that gets inspected every oil change and replaced when needed.
