big trouble with FC

[mazha]

Hi all, I really need help here. I just bought a Nov 2005 Latio 1.5A. Questions:

1. I pumped full tank SPC 95 but could only do 380+km! Thats very little right?

2. Whats the fuel tank capacity?

3. Is it true that other brands of fuel will help with fuel efficiency?

Thanks!

1. Check your tyres pressure
2. Check if the OD is activated
3. How heavy footed are you

Fuel tank size is 45 litres and normally lights up at about 38 litres. With 38 litres of petrol, I am able to achieve 500-520km (80% highway / 20% city).

if i may add on,
check the air filter if it is dirty

Just did tyres, 225 for both tyres. As for OD, how do i check it? please help as I am really new to Latio. I'm pretty lightfooted though, travel about 70-80 on highway.

just did 60,000 km servicing yesterday, changed Air Filter liao. will continue to observe some more and see how it goes. Thanks!

If the OD is activated, it will be lighted up in your dashboard. As for the tyres, I am at 240kpa both front and back

mazha,

Have you tried other brands of petrol?

SPC is known to give poor mileage.

[nakshire]

try going for Caltex... got discount for safra members or OCBC CC users. The techron they have inside can help u clean the engine a bit.

I changed to Caltex and it gave better FC.

I ever tried all brands of petrol(SPC, Mobil, Caltex, now using Shell), I doubt it will make so much difference. I also can travel till at least 500km then top up 37litres+/-, 380km a bit on the low side considering you light footed. Mine is CVT but dun think will differ so much from 4AT.

What about the tyre size ? Has the previous owner upgrade to 16" rims ? It would be about 10% lower than a 15" size.

[mazha]

I will most probably go for Shell cuz my company got corporate card. Gives us 15% discount. Not bad leh.

Shell has this new Fuelsave fuel which it claims can help motorists save UP TO 1 litre for every full 50 litres tank of petrol.

"UP TO" means the maximum it can save is 1 litre.

So it may save you 200ml, 400ml, or just 100ml of petrol.

Might be useful if you provide more info:

1. How many years have you been driving?

2. What is your travelling pattern? Eg. 70% highway 30% city?

3. How many liters of petrol did you fill when you said you travelled 380km?
    Do you fill petrol yourself or let petrol station uncle do it?   
    How many tanks did you monitor?

4. What is your driving style?
    Eg. always redline on pickup? 120kmh or 80kmh on expressway? Etc

5. Typical carrying load? Eg. always in the car alone, always with 5 adults on board? Etc

6. Do you have a habit of waiting in the car?
    Eg. need to pick up GF/wife and have to wait in the car with engine/aircon on?

Note that the most important factor in your FC is as follow (I also driving an 2005 model Latio Hatch CVT)

1. Road Condition - if you drive mainly on Highway without slow Traffic (>80%) (i.e. non peak hours) the FC will be very good at around 12 to 13 + km/lr. But if you are always driving in condition where there is lots of traffic light (start-stopped) or slow traffic (< 60km/h), the FC will not be very good ... at most 11 to 12km/l

2. Foot pressure ... this definitely determine the most. If I am light footed ... I will be at 12+ to near 13 (never reach 14 before as my light could still means heavier to other folks).... but most of the time... impatient driver like me are getting near 10 to max 11.

3. Weather condition - Hot weather I found will consume more fuel... so if you mainly driving in the middle of the day or hot sunny day .. it just consume more due to air-flow, air-conditioning and etc.

So far ... Latio FC can varies from as low as 9km/l to as high as 14km/l ++ as per recorded from our member in the forum.

Thanks

Been driving for about a year. Very light footed. 40%highway - 60% city. Latest fuel top up: 38.5L after travelling 420km. So its about 10.9km. Still topped up SPC 95. Will continue to monitor one more tank and then see how its improving.

I had began to accept the variance for FC of the Latio is alot.  In manufacturing, all factors have a variance from nominal value, and FC seems to varies alot from car to car..  Mine, also not good, around 11+ km/l

Yep, different types of petrol won't affect much, it depends on your driving style, condition of your car and mods.

Seriously ... variance not pertaining to only Latio ... I believe all car similar...

11km/l is common for me but I do know my driving style affect it greatly. Even Honda Fit/Jazz has big variance....

From the look ... your 40% highway is low to achieve good FC. It means in most of the time driving in City, you have a lot of stop/start and max 60km/hr.

The optimal speed for good FC is 80km/hr constant for at least 70% to 80% of the time. It reminds me in the previous forum, there is also a member complaining about poor FC but later we found that it is poor because he travel almost 90% of the time in short distance (< 10 to 15 min drive to work) and no more than 60km/hr. Such condition is never optimal for FC consumption, if you look at the recent Nissan Frugal challenge... the winner is driving around 80km/hr, light load without Air-Con!!!! to achieve around 28km/l for Latio. But we know we dont travel in such condition.

So ... in mainly city driving... 10 to 11km/l is a good number. Mainly smooth highway travel .. 13 to 14 @ 80km constant is good.
Why I say only 13 to 14 @ 80km/hr is good? cause if one is driving above 100 and 110km/hr ... the FC will dropped down to close 11... in fact will be between 11 to 12.

Please also know that pumping will also determine the variance. One pump uncle may squeeze extra 1 to nearly 2 litre of petrol after click, but another could squeeze a little or not at all. I found that after the pump stopped by itself, typically you still can potentially squeeze up to 2 litre in Esso Station.

Overall Latio FC is good in its category.

Cheers ...

hmmm after reading your post,..now I dont feel so bad abt getting 10-11km/l,..coz normal driving pattern,  my wife and I seldom go to expressways,..mainly Ubi to siglap then back to Ubi,..but mileage during  trips up north are amazing for this car,.. once drove up with a santa fe and another with a matrix,... both of them need to top up more times than this humble latio...
