2012 Kia Rio

[2RI012]

Just my two cents guys because i don't know if you all notice this but i do notice that when its raining or when its colder like at night, the car response faster and stronger.

My research and conclusion:
Factors that MIGHT affect our Kia Rio's FC and Performance:
1.hot weather or too HOT air intake and hot engine + no temperature gauge
- hot engine + hot air intake can/might cause pre-ignition in which the ECU will retard the timing and makes the air to fuel ratio too rich = LOTS OF GAS and POOR FC
- since there is no engine temp we don't know if it is a bit above normal already or not.

2.Euro II gasoline (Should be Euro IV)
- another thing is we are putting in wrong type of gas which has a 10% ethanol blend into it, unlike in the US which only has 6% ethanol, but even they said the PURE Gasoline is better than the ethanol blend. The fuel we are using might also be not suitable for the compression ratio of the engine because since its hotter here in the Philippines compare to Korea's weather, their engineer might have forgot to take the hot weather and slow traffic into account.

- Another thing if the timing is too advance and you are using a low octane fuel like 91 or 93(w/ethanol)then you will have a lean mixture not to mention the hot air intake again = hot spots in the engine or pre-ignition, that means you will hear fuel knock!!!

Again take notice guys, if its raining or when it is at night (cooler) see how your Kia Rio response and FC's are
compared to a hot day even without slow traffic.

Kakafull tank ko lang ngayon..

Rio HB

Travelled - 108.7kms
Filled - 12.883 liter (automatic click)
= 8.437 kms/liter

About 40 hiway and 60 city with traffic
Eco mode on and eco driving, shift betwen 2k-2.5k
Caltex gold
803 odo

So far this is my best FC and first time to use ECO ON

hi 2RIO12 ganda ng analysis mo ito nga din gusto ko ipunto sa SA ng casa ko at mismo sa CAC ang kaso ayaw ako pansinin, ano ba ride mo kasi yun rio5 ko may temperature gauge naman at nasa normal level lang sya palagi,as of now ang nasa trip meter ko naglalaro sa 12-12.3km/100L,ave. last week nasa 12.8-13km/100L speed is 13km,odometer ko nasa 1600km na pero di ako nag rely masyado dito antayin ko muna uli full tank and manual computation ko.

nice c_cube ask ko lang ano lumabas na average speed mo sa trip meter?

11.0L/100km ang lumabas nun huli bago ako mag full tank. ngayon plano ko naman ECO On tas hataw mode para malaman din consumption. Natry ko na hataw mode with ECO OFF naglalaro sa 6.5-7kms/liter

sa manual, naka sulat doon: "avoid idling more than 2 minutes". maybe something sets-off after 2 minutes that contributes poor fc at traffic conditions. aircon?(good performance) alternator?(to charge small battery and power steering), or higher than normal engine temp that expands the cylinder walls and makes the piston travel with force required. kaya siguro walang temp gauge ang ex mt ko. kaya siguro dapat rev up once in a while to cool the engine? questions, questions everywhere and not a drop of answer.

Hi guys, just travelled to and from Tagaytay yesterday my route was SLEX and Skyway i'm not sure if its accurate
from half-tank full i reset ODO, up to my home i have 1/4 tank left of tank (V-Power Nitro+ Racing, i just tried it lol!)
i got a total of 130km w/ 1/4 tank or 4.25 liters? can you guys confirm can this be accurate? Revving up to 2.5-3k only and max speed of 100kph only with average of 80-100kph (130kph for few seconds only)

so am i correct to assume 130km / 4.25 liter = 30.58km/L ?? or even just 20+ km/L??
need some experts on computing FC here thanks!! please give me some opinions
i will post the pics of my dashboard tom thanks

He. He. Simple lang pag naka idle.... 0 km gained, x.xx liters of fuel consumed.

Fuel tank capacity is more than 40 L so 1/4 capacity can never be 4.25L. If that is so, you only have approximately 17 L Tank capacity and that is absurd. Correct computation is full tank then reset trip meter. On next full tank, divide trip meter reading by liters of fuel filled.

[chua_allan]

Not sure kung same ang tank ng sedan sa hatch.. pero sa hatch it's 43L. 1/4 nun is 10.75L so if you said 130km tinakbo mo sa 1/4. That's only around 12+ km/l not 20+

[spymaker]

correct. therefore, you have to be idle for 2hrs minimum to get that 6km/l fc for one fill-up cycle. makes sense.

[2RI012]

Hi guys, yeah sorry i did noticed the mistake i was thinking of 1/8 tank and 34 liters as full capacity lol
anyway i did some more research (including the car's manual) i drive an A/T sedan
2 things i notice:
1. Do our Rio's really support leaded fuel?? because it is indicated that we should run it with 95 RON Unleaded fuel, otherwise we might damage the CAT converter.
2. Why is it written in the break-in process to avoid idling the engine for more than 3min??? << what reason ??

Now i did some research again regarding the CAT converter if damaged:

1.The engine loses some function with a damaged catalytic converter. Your gas mileage can decrease as a result.

2.The engine's power may also be decreased. Slower acceleration and power may be noticeable, especially when going uphill.

3.Warning!
A damaged catalytic converter may also cause the engine to run hot, which can in turn cause other damage. The running temperature gauge will show if the engine is running hot.

Problem with # 3 in the list above is we don't have an temp gauge (for sedan) and remember what i said about the TOO HOT air intake + hot engine = retarding the timing = running a rich mixture which in return will mess up the ECU i think for all these variables

The last however i read is that running on a leaded fuel can/might foul our spark plug (can cause misfire) and damage the Oxygen sensor (the one controlling the air to fuel ratio mixture)

Dosent the Rio hatch have a temperature gauge

Sir, as far as I know, lead is no longer used in any gasoline variants. Outlawed na po ito because of it's detrimental effects to human health.

[2RI012]

Once again sorry for that, now i'm dumb founded lol.
So the only possible variable i can conclude now is either the Hot air intake or ECU Timing (air to fuel mixture) or Euro IV fuel.
Hope they fix this ASAP!

suspected ko din nga ito pero nakalagay sa brochure ng kia rio5 euro 3 compatible lang sya,gaya ng ginawa sa hyundai accent they did something sa ecu then ginawang euro 2 kaya ok na accent ngayon

again I will reiterate my early comment in this thread: ECU reflash to EURO2 might be the onlu solution to this preblem. This is the same problem as the Hyundai Accent engine 1.4L petrol in their early batch.

I might be wrong, but as far as I know in that 43L, the reserve fuel is already included which is usually 5-7L of fuel. Depends on the car.

there was a special edition sedan display sa theater mall

... may body sticker, black painted roof ala panoramic, may body kits nga, pero ang gulong yung stock hubcaps pa din hehe

1.2 variant diba? Sinong dealer nagbebenta and how much?
