2nd fil with maybe 25% back roads 17.83 mpg
3rd fill 99% + interstate 19.92 mpg, getting better hopefully just tirea breaking in.
I do have a slight intermitten vibration in floorboard on interstate, I have pulled over and crawled under checking everything out, all looks good.
Feels like side of the road rumble strips about 15%, very faint felt on floor board, nothing else , consistent about every second for a half a second, been trying to figure it out.
Cv's feel good, driveshaft feels good, front end looks good.
I tried my previous oem wheels and tires and still feel, so not the new tires.
I am debating on taking off the front axle drop and trying.
