Problems with Wagon R Duo Mileage

y a..i m sure u shud be gettin that much.... get the Gas filter cleaned too....it requires cleaning more frequently wen the car is new...because the black paint inside the toroidal tank mite affect the filter... also make sure ur Vacumm pipe is in good shape.. cheers... the Valve which Ashish is talking abt the changeover valve...... its got ntn to do wid the MPFI engine... well.. i m in Delhi ..n ppl here normally get 12-14.Depends on traffic....

1. sreemoye ...... cars shud not giv less avg on ptrol .... merely coz .. they r dual fuel ..... unless ur mechanic has unnecessarily changed sum petrol settings

2. sreemoye .......mpfi cars like th duo do not run only on lpg .....they r designed to start always on petrol ... so th q of adverse effect does not arise ....

3. karan ....... has th maruti co recomended that th duo shud b turned off on petrol mode only ..?

4. shrikant ....... most duo owners i hv met at pumps at mumbai hv reported av of 8-9 in ac

5. shrikant .............some servicing might help ... but changing to a better kit wud definitely help

6. jaideep  ....... no repurcussions per se ........even if u use automode for life

7.jaidep ... it is improbable ur av will increase ,,,,normally it wl only decrease with running

Vidhur,

I hope you have asked averages of Mumbai Duo owners who have been using for quite a few months. In which case I should better not expect more than 9kmpl in Mumbai city. FYI, I got 13.5 kmpl on highway.

If Karan is getting 13-14 in Delhi that is because the road network & traffic is far better. I have travelled in Delhi where I could see the change Sheila Dikshit has made in the roads after reducing traffic signals.

turned off on PEtrol mode ???...no dey never sed dat

well ya flyover after flyover !!!....dats true...(to sum extent though)

well karan .... sombody did tell u to switch off ur mpfi lpg car after running few kms on petrol always ..............well juss that in all these yrs ....... i nvr heard of anythin like that ..... n m wondering who might hv invented th theory

well dey've told me to turn in on on Petrol only.... but they havent told me abt turning it off on petrol too..... dats a bouncer !!....

Normally, people installing lpg kit in their petrol cars are advised by the installation company that they should always start their cars in petrol & after 1-2 kms can switch to lpg. Why? I do not know - maybe Ashish can throw some light on this?

My dealer never asked me to do any such exercise with my Duo. He asked me to simply keep in lpg mode, if I want to run only in lpg. The machine will take care of when to go in auto mode & when in lpg.

well the its the Auto mode.. in this mode the car always starts on Petrol,n then changes over to Lpg one the engine ticks 2,000 Rpm...

Jaideep,

It is advised to start the cars (that run on alternate fuel) on petrol because the engine is developed keeping a certain octane number and/or octane range in mind which is available with petrol. The cumbustion properties/characteristics of petrol is different from LPG or CNG. So in order to let the engine settle down well and reach its ideal operating condition it should be ignited with petrol after which the engine can switched over to LPG.
