Car used too much fuel

So we have 2 cars, 2007 Altima 2.5 and 2009 Camry 2.4. Both cars have around 207k KM. The thing is that the Altima uses around 13L/100km all year around. Sometimes its get to 15L/100km in winter and 11L/100km in the summer. The Camry on the other hand is way different. In the summer it uses like 12-14L/100km. And out of nowhere, around October-November, the fuel economy slowly climbs to 15L/100km and then it reaches to 20L/100km. It shouldnt be that bad I mean its my dads car. The Camry I think has OEM spark plugs. Spark plug interval is 192K and its 207K. Its my dads car, and it has no problems so he gets its changed once there is problem. Or it can be because of cold. But the gas mileage cant be 30-40% more in winter.

What caused the previous spike to 20L/100km?
There are many things that could cause a rise in fuel usage.
vacuum leaks
carbon buildup
bad fuel injectors
bad o2 sensors
bad tstat
a fuel leak
etc.

Op, you need to post your dad's driving habits. Is he idli g the car for 20 minutes to get it warm? Is he driving to the corner store that is 100 metres away to play lotto? Is he driving during rush hour? Is he driving downtown Toronto?
A life spent making mistakes is not only more memorable, but more useful than a life spent doing nothing.

It can easily be that bad depending on how it's used.

Has the 2.4 Camry had the pistons and rings replaced? Is it also burning oil (won't be smoking - just not much left at oil change time).

Its a 4 cylinder. Plug change takes 10 minutes and $30 materials. Do it.

Disconnect battery cables for period of 45 min, then reconnect. This will reset you ECU. But Radio code will have to be entered again and radio station.

Nothin caused it to spike. It drives properly. No check engine light

Car warms up properly. But sometimes, what happens is that when I warm it up, the temperature goes down slightly and then goes up when driving. Then it's normal when driving

No, never had pistons and rings replaced. I think it's burning a little bit of oil
