No i am not !! im just trying to make sense of why this happenned ..and asking you pros to throw some light on this ...

and yeah if ford dealers cud gimme the answer for this shan , that would be the DAY !!

[Shan2nu]

I've already explained it to you. Get your tacho, speedo and clutch checked. There is nothing else that can cause this.

That is funny! They can't even get your wheel alignment right, let alone diagnose anything.

Just an update guys -

The FE after a tankful of 98 Octane has turned out to be - 12.50 Kmpl. and thats after driving hard and fast as on the day of the T-BHP meet.

thats a jump from 12.10 Kmpl on the last tankful of speed .

infact it was closer to 13 - but the last few litres were wasted by stopping and starting frequently - so i guess i lost out.

cheers

hey Nc i waited for ur answer.
now let me say my story.


i got a superb figure of abt 15kpl with 98 octane fuel.this included some very high revving driving at the t-bhp meet and at 150kph on the return journey for abt 2-3kms.i.e i cud have got better if i had driving normally.

this is obviously better than the 12-13 that i used to get under similar driving previously with POWER.

i think the reliance 98 octane fuel is total paisa vasool.before anyone jumps on me let me explain.

my tank has a capacity of 36 liters.


cost/liter 48rs(98) 45rs(PWR)


total cost for (48x36)= 1728(98) (45x36)=1620(pw)

fuel

FE 15kpl (98) 13kpl(pwr)

range 540kms(98) 468kms(pwr)

toll to and from reliance petrol pump=40rs
and fuel consumed to and from reliance petrol pump =2litres max.=96rs=100rs max.

total cost involved in full tank using 98 octane=1728 for fuel filled
+100 rs for fuel consumed
+40rs for toll
-----------------------------
total= 1868rs
-----------------------------------------






so for 540kms to be done using POWER i will need 540/13=42 liters of fuel=2016 rs

thats saving of rs150 even under bad driving.so imagine wat it wud be if the speedlimits are kept under control



the economy Fe figures are cuming soon.

Hey SS,

Thanks for the math man...I was considering tanking up my car but was put off by the toll & travel involved in going to the pump. But as you have pointed out that there's actually saving in it..I'm going to go there ASAP!

[speedsatya]

but thats from Mulund.for ur place u have to travel all the way from powai.so before u go take all this into consideration.
mabbe u cud take a jerry can and store fuel ,not in ur car or dicky but in ur garage.
still i suggest u go for it.as the throttle response has improved .also the engine performs better.


only thing that sukks is the exhaust.its become silent

[RJK]

Do they give fuel in jerry cans? I don't think so..if yes then it could really save me serious money man...NC are you listening

[Rehaan]

Hey NC and Speedsatya,

Please try your test again. With 98 and with the fuel you usually use. Note your RPM at 60, 80 & 100kmph, and make sure you are holding a constant speed (not accelerating past the speed) in a constant gear. Let us know if this is still happening.

Also, another possibility is that you were in 5th gear with the 98octane because the engine just felt so much smoother and more powerful that it was only natural, whereas you were in 4th at that speed with the usual fuel. Check it out, im as eager to figure out this peculiarness as you guys are.

RJK, pumps usually dont give fuel in cans due to "safety reasons".

hey NC,
why Speed??
speed is gonna cost u abt 45rs for 87octane whereas u get 98 for 47.xx

[normally_crazy]

dude ,

speed becoz i was outta fuel and was in chembur - dint wanna take a chance with gals in the car - so got speed and besides it will help understand the things going on .. R & D !!

yeah the sound from the exhaust is back !!

cheers

[kbk_75]

Guys, is this Reliance pump a 24 hour pump? I would happily make a run out there at night to gas my cars up, but I can't imagine driving there during the day!

[Shan2nu]

But to tell you guys. 98 oct in our cars is a waste, you can get the same performance and FE even with 91 oct. High octane is directly related to compression ratio. For an engine to gain from 98 oct, it will have to have a comp ratio of more than 11:1.

So, don't get into the habit of using 98 all the time. 91 is as high as our Indian cars will go (except a few that might need 93 or 95 - like the Vectra).

Shan,

except the 95 and the 97 0ctane,i have tried almost everything.but never did i get the sort of FE and performance that i got with reliance 98.and it works out more economical in the long run as i have written earlier.
still would check again and confirm.
