Thanks, Mr. Amhale. Not a secret, it's just that mine is an MT and my city does not have that congested traffic like Bangalore/Mumbai/NCRs

Hope you have fixed the canister issue and the micro relay, if not I strongly recommend you to do so.
I noticed that AT is slightly high revving in XUV to extend the life of the gearbox, especially for the Petrol powertrain. With congested traffic conditions (like Bangalore/Mumbai) it is bound to give only single digits and I expect your FE numbers to improve to a decent 8-10kmpl in City for you. (well actually it is still not a decent number to quote, but for 2L heart & two-ton beast it is not bad neither).
Even Diesel under those conditions would offer just above 10-11kmpl.
What we Petrol heads really miss is that we don't get drive modes hence there is no power/torque limitation that improves FE numbers. With Diesel Drive Modes, Zip is capped at 153bhp, Zap is 183bhp + lower state of torque output and Zoom is 183bhp+420N-m. Zap is very much ideal for city duties.
See if following the below procedure works for you.
Whenever you do an SW update or you believe your car is not giving the right FE, follow the below one (may or may not work, subjected to terms & condt

).
a. Start the car as per the idle procedure given below and take it for a spin. After at least a 20km ride to do this is preferable though. And probably do it before you do a highway run as well.
b. Idle the car for 30-90secs. Turn off the car.
c. Remove the negative terminal of the battery.
d. Press the brake pedal or use the horn to discharge if there is any juice left in the system.
e. Let it be for 5-10mins. Reconnect the battery. Then keep driving as usual or plan a ride in the same week.
Do post me back after doing this and driving atleast 500-1,000kms.
As a ritual, I follow the cold start procedure. And I have penned down a few things I am following (and most of them are plain and pretty generic):
1. Idle Start Procedure: When you take the car, turn the key, let the SW settles for 15secs, then start the car and idle it for 90secs until rpm drops to/under 900rpm. Till then do not turn on the AC or blower, rather open the sunroof + roll down the windows so that the warm air can go out (not to be tried under rainy circumstances��)
2. AC Output:
a. Clean the HVAC filter once in 5k kms
b. Best way to keep the car cool The below is for only MX/AX3/AX5 as we folks do not have FATC
c. Then turn on only the blower, keep in max speed, keep the vent position as face and foot....and use this until you get out of a parking area.
d. Close the sunroof, and turn on your AC with min. temp. + max. blower speed and drive it for about a 5min span, then reduce the blower speed to 3 and keep a desired AC temperature based on no. of occupants.
3. For AT riders:
It is all about with what courtesy we bash the A pedal. Just don't floor it suddenly.
For AT Diesel riders, I do not think anything magic trick is needed for them, they will easily get 14-16kmpl on highways at ease. And the good news for them is, they can check their daily trip FE numbers on the EcoSense page and it is very reliable (Go to Fun With XUV, Choose Zap Mode, Swipe Up then select EcoSense). And M&M for some poor logic skipped this for Petrol ATs.
M&M if you are listening please fix them by adding EcoSense.
P.S: Also please don't plan to delete this feature, spare this at least for the poor MX/AX3/5's like me. 4. For MT riders:
Inside the city do not engage the higher gears with lower speeds. As because, when you pull it from lower speed in higher gear it will gulp more petrol than in the lower gear. This is just because when you move it from 1.2k rpm to 1.7k turbo spools up and burns more fuel. Just maintain the ride between 1.3-1.8k rpm at any gear inside the city. This will also help you avoid frequent gear shifts and half-clutching.
You can observe the same in the FE graph phenomena in the MID). By this, you can avoid frequent gear shifts. Engage higher gears (3rd/4th), only if you see/sense a plain road ahead for at least about 500m-1km.
I was very mindful of seeing the MID FE graph that comes below our FE indicator. This is a very useful indicator to keep up your FE. Nowadays, I am not seeing it as my driving style has now got adapted to keep a balance bw FE and Power (I now keep the Power & Torque graph)
5. Petrol Brand Suggestion:
Preferably fill petrol in the mornings.
Don't waste your money on Shell V-Power. Continue to fill in from the same pump (preferably COCO pumps in your area). Try to continue to fill from IOCL or BPCL (from my experience so far, RUDRA returns good FE numbers when filled there). If you want to run a little peppier and cleaner, use XP95 or Speed93.
Post me if the above works. Fellow riders correct me if I was wrong somewhere.
