This makes a big difference in my observation. A lot of people skip the load factor when quoting fuel efficiency. This can in fact have a bigger impact than the speeds at which you drive or using the air conditioning.

To be fair, the effect of load isn't immediately apparent if you do not have an MID. With the tankfull-to-tankfull method, it's very likely that you've averaged the variations introduced by a variety of contributing factors.

My observation is that it's very easy to hit 22.5+ km/l on the MID when I'm driving alone. With two persons, it's still not difficult to maintain 21 km/l. With a full load of 5 people, it's hard to get 19 km/l on the same roads unless I really put my mind and time into it.

All these figures are true for my 50% city + 50% suburban driving cycle.

Things I forgot to mention is 50% AC usage and 40% City driving and 60% highways with medium-high traffic.

Tyre pressures are also things that most forget to mention as under-inflated tyres loose out on efficiency. Over-inflated would have you bouncy all over the road and induce rattles+ damage to suspension.

Agreed load is an important factor, even for a single person onboard, the FE figures are too good and the road pattern is what we encounter daily; 60:40 highway to city usage with moderate usage of a/c. These are similar to a typical/average indian vehicle. Please do ask your SA at MASS on what he has done, because as far as I know, the ECU cannot be tuned/tweaked without the help of piggyback / standalone units like RaceDynamics / Digital Vampire / Pete's.

The guy who looked after my car from the first service till 80,000 kms has resigned and started his own garage in KA. Don't have his number also.

Will still try and ask the service manager about this issue if there is any such chance.

Or this is purely psychological feeling that makes me drive sedately than like driving on fire types.

Anurag.

From my knowledge, this is definitely not possible. I wonder how he has done it !!

In fact, I have seen many who boast that they have started to gain 2KMPL extra after their first service as it is now 'tuned for mileage'

I am glad to announce that my Ritz has completed 1 Lakh kms today. It has been a total of 2 years and 9 months to reach this milestone.

......

OT:

Thinking whether to get it serviced for 1,00,000 kms or no as I am selling it off and going for a Torque Blue Swift ZDi. Will update the thread accordingly soon.

Anurag.

Awesome Anurag, 100k in 33 months is no small feat.

And congratulations on the blue Swift. I was in a dilemma if I should choose white or blue. Finally settled for white

I bought a Swift after owning a Ritz too. Am sure you'll enjoy every bit of Swift.

Thanks buddy.

Sadly my new swift purchase is delayed to early next year or mid-next year. :(

Anurag.

Possibly, the facelifted Swift will be launched by then. I believe it will turn out to be an advantage for you.

Enjoy Ritz till then!

Fingers crossed for the new swift. Hope they launch it by then.

Guys, don't think its a good idea to drive a Diesel car with very low fuel in the tank. The Diesel fuel pumps don't like near empty tank and can get busted.

Absolutely. I refill the moment the low fuel level warning blinks. No dragging the engine til the last drop of fuel.

I feel it is risky to drive with low fuel in the tank as there would be sediments that would have settled over a due period of time so there is a chance that the fuel pump could get bust ot not work as designed.

1000 kms in 9 days!



I am loving this car more now!

Anurag.

[a4anurag]

The car is now at 103899 kms as of yesterday.

Mileage: 23 kmpl and 21 kmpl (last two consecutive full tank checks)

Rattles: Front passenger seat and somewhere near the left side of the parcel tray. None are irritating but they are evident over bad roads.

Just checked the engine oil and I feel it is too black. The colour is like our hair. The SA says it is normal and he has shown me a Dzire that is at 85K kms with the same oil condition. I am not worried but just a doubt somewhere in my head.



The tyres on the car are nearing to its end. Thinking to change but in half mind as to why spend so much as the car will sold in March or April.

Overall drive ability and feel is still rocking.

I suggest a change. Reasons :

1. You drive quite a lot from what I understand, which also means that you are the one who runs a higher risk. Better be safe than sorry.

2. At the time of selling, if the tyres are bald, that gives the buyer a chance to haggle more. This might offset all the gains that you may have.

3. Tyre prices keep increasing, so you might be better off buying a set now than later.

Thank you buddy. I do drive a lot (110 - 130 kms a day)

Will be going in for Bridgestone S248 (165/80 R14). Will be replacing all five tyres .

Will do it this weekend or by Tuesday.
