How aggressive is your aggressive? Deng can still return 15km/L

Update
4) Fuel Consumption (in the meter) : 11.4km/l
4) Fuel Consumption (self measured) : 12.18km/l
5) Driving Condition : 100% urban within Subang Jaya
6) Average Speed: 30km/h
7) Mileage : ~284km
8) Modification : None

I also feel something's not right with the FC.
Moreover I almost never used the aircond, no passengers, and tires are pumped to specified pressure.

Mine isnt mixed, its full urban.

Interesting.

My previous refuel with 12.18km/l was on Petronas 95.
My latest refill using Shell 95 gave 10.8km/l despite driving with all the same conditions.
Too bad it slipped my mind to try Petron or BHP this round

bear in mind my driving is almost all urban, meaning short trips, a lot of accelerate and braking, traffic lights, etc. not to mention only averaging only about ~30km/h

With more extra-urban conditions I think 15-16km/l is feasible

so far the best i managed was 18km/l on a long distance trip. But that one had an 80+kg passenger.

Petron 95 mixed Petronas 95
4) Driving Condition : ~95% highway, ~5% urban
5) Average Speed: 80km/h highway, 30km/h urban
6) Mileage : 71.6km
7) Refuel amount: 3.9L
8) Fuel Consumption : 18.35km/l

No passengers and aircond was off. Now I wonder how the claimed 21km/l would be possible
Add: The meter showed a supposed 20.5km/l

something's definitely wrong in the formula somewhere.....

Was there anything different done during the 4th service?

And, have you checked your tires if any of them are low on air (especially the front-driven wheels) ?

And, is your urban driving in smooth traffic or constant short trips, traffic lights, jams, etc?

Things I could think of, but may not be likely either:

1. They put in some fuel additive/cleaner which inadvertently affected your fuel consumption
2. During part of the service they did some routine software updating of your engine control unit which inadvertently affected your fuel consumption
3. Fuel is leaking somewhere

That said, do have a proper check of the tire pressures just to be sure

any updates?

Actually

After much observation since my post

I've concluded that petrol brands dont affect consumption

But it is the different pumps at different stations that skew the measurements and give false findings

A pump that refills slower can fill in more petrol before it cuts off, thus giving the illusion the car used more petrol.
