Just got back my second UOA from this truck today. Results are better but still not what I want to see. Iron numbers are down and shearing was not as much of a problem but I just can't figure out why iron is still twice as high as what they consider average. I am considering a switch to RTS or GC. ***NOTE: The first UOA where iron was at 41ppm is on Mobil 1 5w-30. The more recent UOA numbers are on Mobil 1 0w-30.
