I was messing around with my OBD2 reader andwas looking at some live readings.. I did see some readings for my fuel trims.. STFT on both the left and right bank was close to zero....the long term fuel trims were around +8%..left+7.9%,right+8.1%...
Are these pretty normal values for a 160k miles m62? Is the positive adjustment an idication of anything obvious or just an age thing?
No obvious engine issues and no codes....and new pre-cat oxygen sensors..

I'd expect to see a few percent positive on any engine that would have originally been tuned on straight gas and is now running e10. Within 10 precent wouldn't worry me.
