I own vitz 2005.
Engine mileage: 51,000kms
Tyres: 15 inch alloy rim
It is giving +13km/L (ac on and off)
Car produces a sound like a diesel engine sometime or something like foxy sound. A mechanic said all vitz have such sound. Please guide me what should a need to fix. Does it require ecu tuning?
How many Km/L should be given by this car.
Any suggestion on boch plugs which has 4 sparks!
