I have Passo 1.0 (Black), Model 2012 and registration of 2015.
I have been using the car since 2019 as 2nd owner and meter reading of my car is 108,000 Kms.
Initially, the fuel average of car was 14-15 km/l within city (While in Islamabad) but now the average has dropped to 11-12 km/l (In Karachi-Multan).
I have recently changed the Transmission Oil (Genuine Toyota CVT-FE) and got new tyres aswell. I'm using the engine oil (Guard API- 5W 20). Recently got the tuning done as well but average is not improving.
Someone suggested me to change the Engine Oil to Liqui Molly 0W-20.
If anyone can suggest/ recommend any solution regarding the Engine Oil choice and fuel average.
