Red face Which route to take?

Hi Guys,

I have a rather strange question. I can reach my office in 2 ways. The first is 10 kms long with medium traffic, but there are 3 stretches where the speed can go upto 60kmph...hehe..I am talking about peak traffic hours here

The second is 8 kms long with very very less traffic.

However, the time taken to traverse both these routes is the same. This is because the longer route has smoother roads which means I can drive much faster than I can on the shorter one.

My question is which route would yield better economy of fuel and be good for the car?

The idea is to generalise the fact that fuel consumed is equally a factor of time as it is for distance covered. Which means if I am taking 20 minutes to reach the destination irrespective of the route taken, the fuel consumed is the same. Ofcourse, this includes the same amount of gear shifting and clutching. Its just that I have some stretches in the longer route that I can manage to average higher in terms of speed.

Is this true? Experts please

Hi my Fiat Siena Weekend has started to give horrible average eversince I visited Shaman Auto for routine servicing last weekend

My car use to average about 7 - 8 km per litre with 100% a/c in city before the service and now its average is dropped horribly to 2 - 3 km per litre can anyone tell me what could be the cause ??
I have taken an additional engine treatment service alongwith the routine service n checkup the service guy wanted me to take the carbon cleaning also done but I refused since my car was giving good average dont know what they did I m pretty sure they are cheats

I suggest, take the route you enjoy more. The difference in fuel consumption won't be much given the short distance.

I have a question for you. Wouldnt less traffic & shorter route translate into less time?

Shorter route might have bad roads riddled with potholes maybe.

There could be a problem in the quantity and not quality. You may wan to check that too.

@Risga : I believe DieselFan has answered your question.

The idea of my question's answer is to generalise the fact that fuel consumed is equally a factor of time as it is for distance covered. Which means if I am taking 20 minutes to reach the destination irrespective of the route taken, the fuel consumed is the same. Ofcourse, this includes the same amount of gear shifting and clutching. Its just that I have some stretches in the longer route that I can manage to average higher in terms of speed.


Since this thread is about getting max FE, so I wanted to query this. Not that I am very FE conscious.

Hi,
Considering the fact that I leave my house at around 7:45 AM and reach my office by around 8:30 AM ( a total of 26KM one side), I would expect 17-18 Km/Ltr. I fuel in Extra Mile Diesel from Indian Oil. Please also advice should I switch to Shell Diesel ( which my friend suggests is damn good)

Thanks,
Maximers

For driving sake, car sake and maybe some kmpl sake i would take the longer but less denser traffic route.

No you wont get 40% more kmpl but it should be marginally better on the second route.

@ cutdcrap: I agree with Jaggu.......Consider this eg: I was travelling to Electronics city every day by hosur road and the FE of my car was around 12 kmpl. Now I'am driving on NICE road and the FE has drastically increased to 16~17 kmpl.....though the no of kms travelled is more. The meaning of this is even tough the NICE road is little long than normal Hosur road, the newly constructed road is empty and roads are pretty good. I can drive with 1500~2000 rpm @ 80 kmph with any signals and stops.

The idea is if you have more stops in between the FE will obviously come down......

Folks,
Just completed my third service for my scorpio crde @20k Kms.Changed all the oil etc.But not the oil filter or air filter.
My highway mileage which was 12.75/ltr has dropped to 10+ immdtly after service.
Full tank of 60ltrs gives me 640+kms with city/highway.After service the tank dried out (560 kms)just before pondy last week and had to organise cans and fill it up.
Spoke to MPL service Manager-says not possible b'cos we have "not touched anything other than oil change".
Experts pls advice ,what could be wrong? Second fill also confirms 10+.

coming back to the original discussion, i second abhi's point. varying speeds helps in FE.

let me explain this way. you need engine (and fuel) for accelerating. then you can let it coast for sometime and accelerate again. leaving it at a constant speed means leaving your fuel line on just to overcome drag.

you have the drag anyway. in my view the fuel you save is from the saved revs (and friction) of the engine. I have also tested and used this phenomenon. only problem, it irritates fellow road users, and i am still afraid to use it on US highways.

Default Stupid Doubt!

Is there a difference in FE for the following options?

1. A/C always on the Automatic climate control
2. A/C always on the Manual zone

Please don't kick me if this is a stupud question
