Mileage/Average/Fuel Economy(FE)

its all confusing...

if Indian oil octane is 81 and HP is 88, why both are selling at same rates? Indian Oil should have been cheaper.

one more confusing item is, in this era of competition why Indian Oil is selling 81 octane petrol if 88 octane petrol performs better. does this mean that Indian Oil simply cares for maximum profitisation.

i dont have any clue about this octane thing.

very nice review loganromeo.......... u crossed ludhiana by nh 1.........i would have been there to greet you as i live in a place 5 mins from nh 1 ........... i literally want to meet all loganizers......

i dont have any clue about this octane thing.

the octane standard in different companies of petrol determines the anti-knock quality or the resistance of that petrol to knock or detonate..........
petrol has an octane no. rating and each engine has a minimum octane requirement below which the engine will not run knock-free......
if you run your car without the minimum required octane level for your engine, there will be a tendency of the fuel to pre-ignite, thus damaging your engine slowly,
so it's better to know the actual octane requirement for the engine before re-fueling..................

and higher octane petrol will not produce more power or run clearer than the low octane petrol if an engine is designed to operate on low octane fuel...................

Hitesh, my apologies. Actually the entire programme was finalised in a bit of a jiffy. Besides, now that I know that one can look you up in the vicinity of Ludhiana, will certainly look you up some day; I frequent that route fairly often.

my pleasure dear

thanks guys. so basically what i conclude is Indian Oil / HP has nothing to do with Logan mileage.

I completed a trip to Jaipur from Delhi last friday and here are the results:

Total Distance covered: 680 kms
Total fuel consumed: 44.72ltrs
Average Speed: 90kms
Maximum speed 110kms
Total Average: 15.20

Some good:

1. Super secure ride. My wife is the most scared person in the world and she was sleeping peacefully while i was busy dodging.

2. Super comfortable, I intentionally took some bad roads and it came out a winner everytime.
3. AC is as effective as ever. It was on all the time including nights and performed well.

Some Bad:

1. I am an extremely good driver(My family members have different opinion though) and yet an ave. of 15.2? I was expecting a lil more.

2. Brakes are a concern. They dont inspire a lot of confidence over high speeds. ABS is the way to go.

3. 2nd gear lacks pulling power, specially on the hills where it is a must. Anyone also experienced the same?

@adamkathy23:
1. i got some 13.2 odd kmpl on my trip ahmedabad - udaipur - nathdwara - ahmedabad (750 kms) with A.C. on all the times.
2. Brakes definitely are not the best specially above 140 kmph. However they are the same on any other vehicle around. Or rather i would say one must not have experienced non ABS brakes on other vehicles beyond 140 kmph. One has to anticipate well.
3. when i was in udaipur we did go uphill. i was on this trip with my machine only some 300 kms old. i did experience problems driving uphill with A.C. on. however after the trip i completed 1st service of 1000 kms. After this service the problem has disappeared. i asked the service guys to check power and pick up which they did.

ON big hills just turn off the AC .I have no AC and have driven up some Long hills in the Alps but I have never been in 2nd gear for any of them in fact most strait hills I have only needed 4th I suppose you must have some very steep hills or its the AC s fault It does take a lot of power

With outside temperature at 35 - 40 centigrade A.C. stands warranted, specially with kids along. so it is more of necessity rather then priviledge.

A.C. is obvious to draw maximum Power given the conditions. also i was fully loaded with 4 adults and 2 kids.

Hill should not have been that steep. i am talking of this place http://en.wikipedia.org/wiki/Sajjangarh_Fort. there i learnt it was in a 1983 Bond movie, Octopussy. just to refresh (F5) general awareness this movie had many sequences shot in Udaipur.

initially i thought it should not be logan fault.
but then i tried swapping it with second car we had, tata indigo TDI sedan and it was smoother. may be its turbo overpowered.

however as i said the problem now does not exist after its first service and now logan climbs smoothly at par if not better then other cars.

Hey Mir... and Stu....

I should have mentioned earlier, AC was switched off on Hills...my bad!!!

Logan romeo..i am so jealous of you man.... an ave. of 17+... phew!!!

May be i should change my screen name to logan romeo or sumthing... wud it help?

@adamkathy23: this warrants you to get your car checked up. something unusual. Without A.C. it cruises even at full load.

yea ac do grab some power but not too much extent..

it smoothly cruises with full load ........ well truely in my case when i visited many steep hills in himalaya

adam.. I agree with you that you could get better FE and I am sure you will get much better average since you are focussed towards it.

You've mentioned average speed of 90; is it a deliberate and considered effort figure during the drive (ie you were making an effort to keep the vehicle at or around 90) or as per the DIS (ie the average driving speed for the round trip).

In the former case, better FE is solicited, however, in the latter, an average speed of 90 would have meant frequently revving up to higher speeds and rpm; hence lower FE.

Besides, 15+ with ac on for a vehicle this size is commendable; 17+ definitely desireable though!

The issue of power in a 1.6 is not a concern; to be honest the primary reason one had decided to go in for a 1.6 was a perceived concern for adequate power in a 1.4L engine. However, with ac off for some stretches the power issue can be resolved.

A word about Sajjangarh Fort in the Arravalli Hills near Udaipur; the area asks some serious questions from any automobile; Mir is right about it. Besides the roads are narrow, for most parts single lane and sharp bends; ghat sections (steep climbs) appear out of nowhere. One cannot hold a consistent gear for long! Last I went there was in 2002, things would not have changed radically since then I guess.

I have also driven extensively along the Swiss Alps, the longest drive starting from Spiez (on Lake Thunersee) near Thun - Luzern - St Gotthard Pass - Biasca - Bellinzona - Lugano and on to Isone (where the Special Forces School of the Swiss Army is located high up in the Alps) and then crossing over into Italy. The altitude is definitely more that of the Arravallis and more snow of course, but the roads are a lot better, much wider and allows the vehicle more breathing space (and obviously as Stu says, one does not need any ac). I had a Subaru 2.0, which of course also helped. Comparing the two drives are like comparing apples and oranges.

adam..since you are in Delhi, would be a pleasure interacting and sharing details!

I use a fuel with 98 Octane this is the fuel recomended by Renault  

What is the matching fuel in india??

I have read somewhere that filling up the fuel during early hours of the day would result in more fuel, as the density of the fuel will be higher than filling up during hot afternoon.

Is this true?

Yes you may get one teaspoonfull more than at midday
Stu

F1 uses frozen fuel to get more into the tank

the difference when compared to logan tank is too negligible. meaning by if you are passing by a gas station in early hours and if there is nothing queued up it is a good idea to get a refill done.

but the advantage is not enough to make one specially visit the gas station early hours.

Mir has hit the nail bang on the head... I have met people who take an extra ride just to fill petrol from a certain pump at a certain time.. the amount of fuel spent going out of the way in an odd time for this is way higher than the spoonful of extra fuel you actually get

haha yea thats true....

i too have encountered many such peoples...

i simply fill from a single pump to get consistent fillups.

I just fill up !
