I've gone from an average of 46mpg to 49+, and I just have over a 1K miles.
This is way cool!
UPDATE!
Next day went on a 110 mile round trip. Average went to 51.7 traveling at 65-70mph. Would have been better if there was less traffic.
I didn't think I would be in this range until first service was completed. WOW!
This is the stuff dreams are made of.
