fuel consumption
-
can anyone give me some list of aftermarket products which can improve me fc?(now 1 tank less than 350km)
-
there is no aftermarket product that actually works in saving fuel, all those are snake oil...dont waste ur money on those. best fuel saving is ur driving style and expect a evo9 to drink so much, its normal.

wad car are u driving?

I am driving a manual Nissan Sunny FL. Everyone says it's a drinker but my average FC is 15km/liter.Originally posted by jashbonbon:can anyone give me some list of aftermarket products which can improve me fc?(now 1 tank less than 350km)
Not achievable? Some light modification and simple habit I have done:
1) Be merciful on your right foot....this is where most fuel are saved. I try to maintain 2000rpm but PLS DO NOT ROAD HOG.
2) After run in, change to full synthetic engine oil.
3) A simple cold air intake modification that cost me $60 (my car not fog lightso take the air from there)
4) Change spark plug every 20K(use only original parts)
5) If no need to much aircon, control abit cos this will saved u 5 - 10% fuel.
Pls take note city drive and highway makes a big difference.
Other gadget I have not tried but like someone says....machiam snake oil.
Good luck! -
i shift up before 3k i seldom use aircon leh ... maybe its the car type tat matters ... but somehow i think something could be done ... cause my car smell like petrol station when i stop at traffic like .. i think using too much excess petrol?

how long have u been driving?
estimated percentage of city/highway/idling at east coast? -
he driving evolution leh.. how to get good FC...
-
If you're lucky, you can get 8km/l on the rx-8, so your evo9 shouldn't be that bad.
-
you won't really notice the difference between city driving and highway driving in Singapore .... -
what a joke. buying an evo 9 and worrying about fc.
-
turbo engine usually run richer, thats why u smell alot of gas at the traffic light, it could also be tat u decat ur exhaust system. for tc car...min recommended requirement is 98. well, already said dont expect ur evo9 to drink less even if u dont rev hard and u shouldnt be worrying too much about ur FC if ure so concern then dont drive.
-
I'm not too sure about TC cars. But can you lean your fuel regulator. Get after market one that has a varible settings. Cause you said that you smell petrol when idling, my best bet is that the fuel is too rich. SO too much excess of fuel not combust.......
But i also got mechanic that says if the fuel is too little in the combustion chamber , it might cause some problems. I think better to get the car to a mechanic and tune the fuel regulator. At least, anything happens can blame on mechanic.
Sorry, if i can't be of much help.....

ty all ... its not really to the extend that i will reduce my travel ... but jus trying to save some money ... i mean doesn't mean buy evo then can anyhow throw away money ... got lotsa of loan to pay each month wat ... so need to save a bit here and there ...
-
Before you bought the evo9 you know its going to drink fuel like no tomorrow, and the loan that has to be settled monthly won't be cheap either, its like its like.......it just doesn't add up.Originally posted by jashbonbon:ty all ... its not really to the extend that i will reduce my travel ... but jus trying to save some money ... i mean doesn't mean buy evo then can anyhow throw away money ... got lotsa of loan to pay each month wat ... so need to save a bit here and there ... -
bro, i wouldnt recommend u lean ur mixture. its better to run rich then to run lean n risk blown engine. 12.3 afr would be gd,not the reco 14.3. i notice not much difference too when u rev full tank,or u drive conservatively full tank.just do ur regular servicing n change ur fuel filter at regular intervals. invest in gd tinting so ur aircon works less hard,all these helps. oh and reduce any weight u can. check ur oxygen sensor too.

my air fuel ratio is always 14 .+++ one

Change to a different type of aircon gas. Well, that's what one of my customers told me. He did it on his own car and said his FC was lowered by 10%. Got to do with rate of compression gas thingy which in turns lesser work load on the compresser.
-
diff type? theres only one type which is R134A....the older one R12 is long ago phased out cos it contains CFCs....Originally posted by newcomer:Change to a different type of aircon gas.

ok wad....thats norm ma...rich is 8:1 for AFR...Originally posted by jashbonbon:my air fuel ratio is always 14 .+++ one -
14.7 is usually the AFR used by most car manufacturers... turbo engines are usually hotter than NA engines so manufacturers will introduce more fuel to cool it as well....other than that, running richer is also to prevent knock...so if u want ur engine to blow, u can try to lean ur AFR

Nv heard of this type before, is it the same as HFC134A? Anyways, the person who recommended it to me is a businessman, so I don't think he'd try to cheat me bah.... Besides, the conversion cost less than a hundred bucks. Anyways, this type of gas is still new in the market and currently, only York (the aircon company?) uses it in their new lines of aircon units.Originally posted by AE86tofu:diff type? theres only one type which is R134A....the older one R12 is long ago phased out cos it contains CFCs.... -
