OK should have googled first, but I just didn't see that weight as bringing me down all that much.

Weight of vehicle with only me is about 4300 lbs, with the extra passengers last night it would have been at least 4800 pounds. So that would be a about a 10% increase/decrease (depending on how many people are in the car) from the other weight. Based on the figures in this link (https://www.h3xed.com/blogmedia/Rica..._MPG_Study.pdf, I could expect 1-2 MPG hit by increasing the weight by 10%.

But still, that is a good 4 MPG.... Perhaps the incline had something to do with it as well?
