My FC getting worse.......help!!

[jliow]

Dear Bros and Sis

lately my Latio 4AT drinking petrol like water, and net yet 5K servicing yet......my driving conditions worsen a bit lately as I encounter a number of jams, but lately my last 2 full tank dry up before reaching 400Km, and I top up abt 36-38L. I used to get abt 12.5FC, but now less than 11....somethings wrong? I also try to maintain my rpm at 2K most of the time, sometimes overtake will hit 3K, but very very seldom...

any suggestion ?

Yo Bro....i believe alot of lations share the same setiments as yours with lots of qns on the FC....like mine also has drop but mainly due to my route of travelling and % of highways vs cities area..so really gotta gauge the rational behind lor... Anyway, few factors that may cater to the reasons behind although some may / may not agree lah 

Air Con adjustment (How cold / hot you adjusted)
Tyres (Air inflation did you check freq)
Traffic Congestion (Traffics also need to consider the idling time, stopping period)
Foot how heavy (Heavier you are, more it will lim your petrol)
Speed constant (Maintain proper speed all the way to avoid unnec wastage of petrol)
Way of driving - Sudden brake / pickup, etc..(rem any sudden movement sure pump our ride heart heavy big time)
Route Area (City vs highway %)

Any more to add on Lations????

Hi Bro....for your queries....I did the following

Air Con adjustment - usually 23-24, after I drop my wify I turn off aircon for the rest of my ride.
Tyres (Air inflation did you check freq)- yup every 2 weeks
Traffic Congestion -variable, route in the morning always go via Kaki bukit viaduct. sometimes jam, just roll and roll,
Foot how heavy (Heavier you are, more it will lim your petrol) - not always, only when I encounter idiot drivers hogging road....
Speed constant (Maintain proper speed all the way to avoid unnec wastage of petrol) - usually between 70-90kmph
Way of driving - Sudden brake / pickup, etc..(rem any sudden movement sure pump our ride heart heavy big time) - seldom la, but sudden brake sure have when u kena idiots driving or cutting in dangerously
Route Area (City vs highway %) humm...no highway, but 50% road jams, 50% no road jams..

I scraped the curb a couple of times, but dun think that will siong my car FC...then again who knows.....

Add on:
1) Dont forget any modifications that u had made.


By right on mineral oil should have the best FC.

All very original.....

Huh? I tot syn oil will have better FC than mineral oil?

[beluga]

What's the recommended pressure for the tyres? Using stock tyres here...

[Jazz]

Yep, synthetic oil should have better FC. 

[jliow]

I think I know what happen.....last 2 full tank I use SPC 98, KNN the oil burn like no tomorrow, 80K, reach 1st quater tank.....

Today I went to pump Esso 5000, reaching 60Km, but not even hit a quarter of my quarter tank......

Got like that one meh?

Anyone got such experience?

Try to recount if u recently had done anything to ur car..a friend of my driving a Toyota Isis once had his wheel scratch a kerb..he thought it was fine..but as he drives..his FC plummets and after sending for investigation..the mechance told him his wheel was like actually slanted in..and he had to spend some $ to repair and eventually his FC returns...i cant recall whats the part that was spoilt though

[law]

my last tank hit 377km only, pumped 35L, 100% city driving 

so far noticed tat 95 gives better mileage than 98.

Humm..thanks....ut I am very sure the wheel never kena, just the lower part of the bumper scratches kerb, i think its me, not used to the low bumper skirtings, lucky the scratched parts are not visible, i checked the heels alignment also...looks ok

I pumped 230PSI on front wheel and 215PSI on rear wheel...not sure what bros and sis who got good FC pump here, I just follow th e label.

Yep, synthetic oil should have better FC. 

Just to share with you guys, during 10K (Km) service, I was told by TCM staff, changing to synthetic oil can give better FC. So I spent my hard-earn $80 for the so-call top oil. 0w30.

End up, my FC drop from 11km/l to <10km/l. I've already monitored for two full tank. The bloody FC stuck at 9.5~10km/l. My driving patten never change, 10% highway.
My $ thrown into drain. I'll never trust TCM guys again.

hi bro try pumping to front 270psi rear 250 psi as after i did that my fc from 12.5 become 14.5 after pumping. max for stock tire is 300 psi.

Is this pressure able to be used for 215/45/R17 as well? i not surre what pressure to pump..

[totallypatrick]

i pumped 240psi for tat size. My fc is about 12.X per km on 17".

actually he is not lying, thiiner oil should yield better fuel efficiency.

not advisable..... ur tire thread will wear out faster in the middle & given tat stock tires already skidded easily.... u are contributing more postential to skidding with such PSI.

dangerous, so take care.

[Novellus Legends]

10% highway...even any car will also has issue FC unless u driving a HCH wich will fetch u a crazy FC of 22km/l upwards for ur scenario

Ya very agree the stock tyres already don't grip very well. maybe I will increase a little to the front....say 245 and  rear 225...

So far this is what I feel when I change petrol

SPC 95 CMI, no power at all so make me squeeze more oil
SPC 98 got power, but burn like no tomorrow, esp when idling or kena jam
Esso 5K....Good power, burn slowly
Esso 8K Good power, burn somewhat quicker?? To be confirmed
Caltex sliver: not bad power, good burn rate, not too quick
Caltex Gold and above: no chance to try yet, too exp.
Shell 95, no diff from SPC 98
Shell 98, no diff from Esso 5K but pricier
V-power, dun think will try until they day I drive to Malaysia.


My conclusion....stick to Esso 5K ....
