mine 2013 altis 1.6 1ZRFE gives 10km/l approx with light foot . did everything cleanup(throttle, manifold, injectors, AFR) and at last the culprit was spark plug. change to old spark plug i.e SC20HR11 with 1.1mm gap set. previously old owner mechanic set that gap to .8mm.

Total running kilometres divided by petrol liters.. total 76k km driven

That means i should go for tuning and throttle cleaning.. and whats the function of plug gap size

pre ignite and delay ignite search google for explanation. the main thing which i know that every engine is designed for a specific gap size. i set that gap by readings service manual of 2009-2013 1zrfe engine. the range vary from 1.1mm to 1.3mm. you should try 1.2mm. but manual recommended SC20HR11 which is now replaced by SC16HR11. denso ones. here every mechanic set gap to 0.8mm which was old carb engines gap.
anyway i shared my experience. 10km/l is calculated on full tanks and total km covered while meter shows 10.4km/l-10.5km/l.

Thank you bro for your guidance and i would go through my vehicle's user manual to know which gap size is recommended for mine.. jazakallah

1.6 altis has 1z rfe so preferred gap is 1.1mm. check plugs will be iridium too. although people donot recommend iridium gap setting but due to the price do it before buying new ones
