I don't recommend to replace everything for the Corolla. That'll be pricey. Just replace what's really due for replacement.
If it's FC you're concerned about, start by checking the ff:
1. Engine oil - when was the last time you had your oil changed? What oil rating and viscosity are you using? Fully synthetic or semi-synthetic oil can give you a slight improvement in FC over regular mineral oil. Also make sure to replace your oil filter, preferably with an OEM one.
2. Spark plugs - as far as I remember, the Corolla doesn't use iridium plugs yet, so you have to change plugs every 20-30,000 km. Again, make sure to use spark plugs that are OEM spec to get the best power/efficiency.
3. Air filter - have your filter checked if it's already clogged. Usual replacement of filters is every 10-20,000 km depending on need. Replace if necessary.
4. Fuel filter - again, could already be clogged.
All of these are cheap maintenance items - it won't cost you more than 3k to have all of that replaced, since Corolla parts are cheap, and many shops in Banawe (and all over the country actually) carry them.
