Altered my work route, now is 10 miles, about 15-20 minutes. Route has a big impact on this car's MPG, and the shorter 7 minute route, which I abandoned pretty early on, was an MPG killer. But even the longer 12 minute route wasn't helping, and additionally I was worrying about 12 volt health (unwarranted I think), hence the switch.

A note, early in this tank I had a gas gauge blip where the gauge, in stop and go traffic and hot ambients (95F), without warning "increased" the number of pips to suddenly read as a full 130 miles into the tank. The odometer reading was fine, but the multifunction display mileage zero'd out. This can be an indicator of a failing 12 Volt battery (the Goofy Gas Gauge issue), but I'm not seeing any other issues for now and these cars can have issues with their fuel bladders.

It's an absolute struggle to maintain any semblance of decent MPG with the AC use given the temps. Really pretty disappointed and I hope this isn't the harbinger of another issue like a failing hybrid battery.

Does not like using AC. Not sure how to mitigate MPG hit from that as it's a non-starter (to not use the AC) here in the South; it's May and the temps are already in the upper-80s.

Combination Meter went out for a 15 minute trip and I googled the distance (12 miles) and added it to the odometer number. Combination Meter is getting replaced tomorrow.

Also, added upper grill blocker at some point (maybe 1/3) on this tank.

Furthermore, temps have become winter and this car suffers from the bad-mpg warm up cycle.

First tank! And while it's below the ideal EPA numbers, I'm still learning how to drive this (there is a technique), and my normal route is less than ideal (as compared to the EPA settings). So I'm happy so far, with the Corolla this is a 29-32 MPG route.
