M800 mileage query

nosfreak · 9th March 2006, 10:08

Hey ppl, V bought a M800 2005 November. Till date done 5900 kms, Well on dec 23 v travelled to Vijaywada where the car first service was done already. The car gave 16-18 per litre, doin a avg of 80 to 95. Then again on March 4 v went to Vijaywada again, n the car gave 18-20 per litre, n the second service was done on Feb, Avg speed bout 85 to 95. So guys i wanna know whether in the next service will i get more mileage? n whts the max mileage of the m800 n speed? my old m800 used to give only 18 per litre, n did top speed of 120. n also i have few query of my music system, will upload pics n expalin the problem.

his nosfreak!

i have a m800 (mar, 2000) which i regularly take out for long journerys. within city i get a mileage of 15.5 to 16.5 while on the highway i dont get nything less than 20 (this car doesn't have a/c). once on a trip 2 agra i got a milage of roughly 24, i dont know how. i usually drive it between 80-90 kph with no sudden dashed.

also as u said 16-18, on a highway trip u are always sure of how much average ur car gives between refulling a tank, so pay little extra attention 2 this and u will know the exact average. cause between 16 and 18 there is a huge gap if u were 2 travel 300 kms. its almost 112% difference. no offence meant bro.

i m sure the mpfi engine will regularly give u 20+ average for highway travel. enjoy the best car ever built.

nosfreak, engines' fuel efficiency don't increase 10% after every service.

In ur case, the engine and other parts were slowly running-in. So, there was an increase.20kpl is pretty good and it might stay there.

hey thx guys, yeah i know i wont get more mileage increase in every service done. from Hyd to Vijay is bout 280 to 290 kmph, actually mr bros m800 gives 21-22 in highway, hes done 3rd service, he said actually after 3rd service the car sets its itself, u know wht i mean. anywayz i dont have a/c in my car, so in city i can expect 16-18 n highways bout 20+?

kmph? its kmpl right?

and shibup's M800 5speed gives him 17kmpl even with the freeflow. Impressive.

and nosfreak; see taht your post is more legible and try to avoid chat type post.

Easily. My M800 (non-a/c, 1985 model) used to give 22 and more on highways. Never really checked the FE in Chennai, but would assume that it must be between 16-18.
Don't worry mate. I don't think there is any other petrol car that can beat the M800 in FE in India. ie. unless the Suzuki Twin or some small car comes into the fray.

Erm, theoretically, a good free-flow exhaust will decrease back-pressure on the engine. This in turn increases overall efficiency, leading to slightly better mileage. Iceman's 12-13 kmpl Baleno (in town, with AC) is testament to that.

stop tempting me ! free flow is no good :((

karthik247 · 9th March 2006, 22:39

It might help to increase the FE, but people rev hard till the redline for the sound so naturally, FE drops

nitrous · 9th March 2006, 23:09

The reason FE goes down is that free-flows sound at mid & high revs.
We all want to hear that exhaust roar as often as possible and shift somewhere below the redline.

yeah and a certain Ikon 1.6 Sxi with free flow giving 12 kmpl as daily driver is another testament too.

hot_rod · 9th March 2006, 23:31

viper and karthik are right free flow is supposed to increase fuel effeciency as it takes presure off th engine so in short a free flow is good!as per the mileage of the 800 i get nothing less than 18 in my 96model!

nosfreak · 10th March 2006, 08:37

kmph? its kmpl right?

My Mistake , Kms. I dont rev the car so hard, hey also which r the best way to yeild better results on highways , like shifting the gear at wht speed? Also stock M800 v get radial tyres, so i put around 27 in front n back too. Is that Correct ? how much psi do i have to put?

Also i know this sounds a little awakrd but can abtter suspension be fitted in M800, caz my car was a lil low @back caz of the speakers, I have a Blapunkt Bass tube, Two Velocity 6 inch woofers (kinda old) boxes were made, n plus Two Pioneer Speakers fitted to the dig key, SO this kinda put weight on the car, where whenever theres a big speedbreaker ahead, the rear bumpere always touches, But for now v have removed da Velocity woofers, n the cae seems to be better nown the rear bumper doesnt touch a lot. But im kinda a sound freak so i really miss that rear woffers in the back, caz whenever i sit at the back i get to clean my own ears with my fingers while sitting @ the back in 2 min

. also got to 2 mid range speakers of velocity in front, crossovers, Pioneer amp(will check n tell u da watts of it), n Also got the Latest Pioneer Stero (will check that too).

So any chance of chaging the rear suspension for a better one n how much will it cost?
