before using such product; better make sure the engine is in good condition.
for aged persona;i recommend to
-clean your engine from any grease first
-change your valve cover gasket to new one
-change your fuel filter
-clean and reset your throttle body
-change to K&N air filter
-use 5W-30 engine oil
-use new spark plugs
-use Caltex Techron injector cleaner.
-check or replace your purge valve canister.
hopefully your Persona will be much better.from my observation;u can get 300-350KM per 35 liter of fuel for 100% city driving if u keep your engine in tip top condition.
nothing we can do about the sluggishness below 2-3K RPM.but u can try to minimal the effect by
-remove your catalytic converter
-use 4-2-1 extractor
-use lightened crank pulley with same size as OEM.
