My question is regarding fuel consumption of Wagon R after second service.
Recently on Sunday 25th of July, 2016,I got second free service (oil change, gear oil change, oil filter change, air filter not changed, as the mechanic himself said, it was okay) of my car at 3700KM (i was reluctant to have 2nd free service at 3700KM, but people there at 3S there told me that i need to get my Car's second free service after 5K KM or 6 months, whichever comes first, so i went for it).
Anyway my question is, that before 2nd free service, i was getting fuel average of 12 to 13KM/L with 80 to 85% AC on within city. And now don't know what has happened, that after 2nd service instead of fuel average getting better, it has suddenly decreased to almost 10KM/L with same usage and on same roads and almost same traffic (when i would get 12 to 13/L before 2nd service)
Has the mechanic there done anything wrong? Should i take my car back to 3S or is it normal that after first oil change it initially consumes more petrol?
The mechanic there (at Suzuki Township Motors) was lethargic. Tho they have good mechanics as well, but the one i got last time was not good. He did not do satisfactory work.
If someone could suggest me what should i do?
