Mine is 2.0 Forte,
100% highway driving at +-110km/h : FC = +-6.1L/100km
If mostly city driving : FC = +-10L/100km
*
The FC on my 1.6ex seems significantly higher. sad.gif
In my two recent 100% highway journeys, the readings show

1) 6.8 l/100km (with 70-100 kph, 2 orang, just before 1st 1K service, to LCCT)
2) 7.6 l/100km (110-140 kph, 2 orang+40kg barang, after 1K service using mineral oil, from Ipoh to KL on PLUS toll-to-toll non-stop near mid-night)

Are these within expectation? Any comments on the higher FC, especially the 2nd one?

Use BHP 95 all along. My FC for urban driving around 11-13 l/100km.

The car is fitted with BK (from Naza, along with 15" alloy rims). Does it cause higher FC?

Mineral oil will give worse FC. For me, synthetic improved it by 1-2L/km.
But your numbers are pretty similar to mine (but mine SX la...)....

If ur EX model FC is high, even with full syn oil, i doubt something might be wrong with ur car....
mine SX FC not high at all....

Yaa..i have to admit that using the mineral oil will do the 'damage' to the FC as compared to fully synthetic oil. at least that was my personal experience. ...
...
As an addition, the BK might also (slightly) contribute to the extra FC as it added extra weight to the car + extra surface area to be dragged by the air when the car moves. ...
Note from the equation that more surface area (like installing BK) will contribute to more FD = more FC.
The most important thing & worth to note is that the FD increases with the square of velocity. So every km/h increase in speed will significantly contribute to the FD value thus the FC will also increases significantly. This explains why the FC is very high at a high speed coz the engine need to produce more power to overcome the high drag force. Am i sounds too technical?  whistling.gif

Appreciate your informative comments and explanations thumbup.gif , in particular from sifu izputra. notworthy.gif Now I understand why my EX's FC appears somewhat higher than expected, especially when it speeds.

Contrary to izputra's analysis, a SC manager asserted to me that BK improves FC, which I'd doubt, but lack the technical knowledge to question him then.

Also i did not realise fully syn oil does improves FC.. Used mineral oil for 1st service because i was told that for new car better get oil change more frequent, thus better use mineral oil in the 1st and 2nd service... then switch to fully syn subsequently. Anyway, will follow your advice in my next 2nd service: use fully syn oil. Thank you again. smile.gif

If there is such rule that we need to use back the "naza" logo, I think Forte sell will drop more than 30%......

Agree! I would not have bought the car if i am not allowed to replace the N logo... That was the 1st thing I did to my new Forte.

... Go to the Consumer Tribunal if they refuse to refund you. The Consumer Tribunal will fight for you for RM5 which is all you have to pay when you lodge a formal complaint. (Make sure you keep all the records)

No point highlight to HQ nor Careline. They are one and the same.... They are just good at saying, we will check and get back to you (which they never do). Personally, I have heard this more than 10x... even 2-3 emails from CMD Naza HQ saying the same.... Its total BS.... Naza could handle it better by not making empty promises every time they fail to deliver. This just goes to prove, NAZA CMD is a real joke and is 100% not committed to resolving your issue, they just log down ur complaint and thats where it ends.

I don't agree with making 1st class attention, it just frustrate you when there is nothing you can do about it but make yourself and some Naza staff miserable.....

Bro bmkia, i can understand your frustrations. Though not as bad as you, I have had almost similar feeling in my dealing with the company's Careline / CMD. Still, I think it is better to lodge any complaint there first, at least give them a chance to resolve it, despite their unmindful attitude, before (and be prepared in) going to The Consumer Tribunal.

But the worst experience I have with the company is their blatant denial and/or distortion at their management levels (such as sales manager) on sales promises made. shocking.gif vmad.gif The dishonor practice reflects little if any due respect to basic consumer rights. Perhaps this is not uncommon in Malaysia, but certainly a disgrace.

As a bro once put it, "the car is good, but company lousy." (as he sold me the k-emblems...)

The bitter lesson is: as or before you make booking and d/payment, insist that all sales promises are clearly documented, signed, and chopped.

Aiyaa..kindly dont call me sifu laa  blush.gif  Me also not expert enough. Maybe i'm wrong also. i just try to recall back the theoretical parts of Force & Aerodynamics for practical purposes. hopefully my memory still serves me well..already 9 years leaving college u know & i did not practice it either on my current job tongue.gif
Somehow your SC manager's  statement might be right also. If the BK was designed & tested properly in a wind tunnel (to get the best design for streamline air flow especially under the car), the BK might reduce the Drag Force (FD) under the car thus improving FC. But this improving FC figure are ignorable/unnoticeable at a low speed. It is somewhat more noticeable at a high speed cruising. In conclusion, i'm not sure enough whether our versions of BK that available here are properly design (for streamline air-flow) & fully tested (wind tunnel) or not? At least the BK do the justice to my eyes coz our Forte looks very nice & sporty with BK actually  thumbup.gif

Noted, and thank you for sharing your professional knowledge, bro izputra.
