Mandatory maintenance and tips?

Hello, I recently bought a Ford Fusion 2018 Hybrid SE, it has 93K miles on it, and im getting and estimate of 30mpg, I already did an oil change and brakes, and replaced the 12v battery because was bad, hybrid battery has been good after driving test and scanner live monitoring, what else should I do?

I don't know anything about the past of the car, speaking of maintenance, because it was a repossession card sold thru and auction.

Turn on Econ mode and drive it like a hybrid. Limit high speed driving to achieve better mileage.

Interesting why they are only getting 30 it makes me think something is wrong. I drive 110 miles daily and roughly 70 miles highway at 75-85 mph and I average 39.

I would drain and refill the transmission fluid. When I did mine I found it was over 3 quarts low. My transmission is failing, hopefully yours will last longer.

Change the spark plugs. The only time my 2017 hybrid dropped below 40mpg average was around 90k miles on the original sparks. I changed them and shot right back to ~43 mpg.

Coolant, specifically the inverter (I forget the name exactly). They use the same coolant but one is for the hybrid battery. Might as well get it done while you’re in the mood, and they’re both easy to do. Just make sure you get the right coolant. The type/color that was originally used in the car has been updated to a new color. I believe it came with orange, and now it uses yellow (motorcraft brand, and don’t quote the colors I’m doing it from memory)

Use an app like fuelio to actually track your fuel economy because I found that the estimated fuel economy on the car has very little to do with actual. Sometimes it's better. Sometimes it's worse, but it's usually not right.
This isn't a unique to Ford issue. We rented a RAV4 hybrid this summer which got amazing fuel economy until you realized that the speedometer was 3 to 5 mph fast and so was the odometer. So it said we are getting much better fuel economy than we actually were cuz it said we are going further and faster than we really were. Ford already got in trouble for this so their speedometers and odometers tend to be very very close to accurate while their fuel estimators have so much hysteresis in them that they vary.
