Well, I feel a little stupid but also excited to have figured out that my mpg can be found in different ways. I've been looking at the ongoing readout on the empower screen option (finally hit 41mpg today!), but today I checked the trip 2 readout, which I had reset at my last (2nd!) gas-up. (The pump shut off early, at 3/4 tank for some reason, which is actually what I wanted and what I did at my first fill-up, preferring not to carry the extra fuel weight of a full tank.) Anyway...the trip 2 says I'm getting 43.7 mpg! Yay!

Another dumb question, then: what is the empower mpg reading from? Some accumulation but what accumulation? Is that a lifetime reading?

From the last time you reset it with pushing down the OK button for five seconds or when it goes to zero. I always reset it when I reset trip gauge.

I turned off the cabin heater despite it being 50F this morning and most of the trip was EV; I went from 40MPG to 54MPG, Spring/Summer is not getting here fast enough this year, at this rate I'll be planting stuff outside at the end of May.

I have used 3m clear film to cover my large middle grill, my fog lights, headlight seams, and inoperable body seams. Time will tell...

Just watched a video for the air filter. Not quick, but also doesn't look complicated at all. I may crack it open and see how it looks. If it looks like my cabin filter, I'll be glad to change it. Ordering air filter now!

Can't find any videos of the spark plug change. I'm half scared to mess with it, knowing that plugs can break, get corroded onto the block, get stripped, etc. Why mess with a good thing? Unless, the plugs are crappy, the wires old and tired. Since my car has a lot of engine use from freeway driving, and I don't have any record of a spark plug change, I feel like it might be a good thing to change them. Will keep looking for schematics etc...

Got my new/used audio module installed today. Took about 10 minutes and came with a free motivational cd. Hahahaha.


The hardest thing to change is the cabin filter.  If you can do that the plugs and the air filter are super easy.  You have to lift the engine cover off in order to get to the air filter.  The plugs are right there.  a deep socket set will help you get the outer plug coils off.  The plugs are easy to change.  Good luck with everything.
