Hey All, Have a 2016 Prius Four that just crossed the 130k mark and my mpg is hovering around 45-48 which is pretty low for me. As for big ticket items I have replaced the spark plugs and all four rotors and brake pads around the 120k mark. I know the previous generations recommended MAF cleaning to improve fuel efficiency but is that needed for the gen 4 as well? Also, is there anything else I'm missing that can contribute to my lower mpg? I'm up to date on the usual items... 1. oil/filter changes 2. cabin and engine air filters 3. hybrid battery vent cleaning Perhaps when I got the brakes replaced they didn't grease the calipers? Or maybe the battery is finally dying on me. Let me know if I'm missing anything else!
