High FC on Nissan Sunny 1.6 FL Manual
-
Hi Guys
Please tell me is my FC 11.4Km/L normal for manual car? I am changing gear each time at 2000 rmp the most and why I can't hit 13 Km/L ????? My mileage now is just 4600KM. Going for my second servicing soon. Hope to hear from anyone soon.
Cheers,

yes my sister in law also has a 4 months old Nissan Sunny and it is Auto yet the FC is very low, average only 10km/l so your manual sounds quite right in the range. It is a characteristic of Nissan's high revving engine (notice the gears change down too fast each time and revs pick up too quickly, hence FC is higher , instead of the better low-end torque from VVTi engines from other makes like Honda and Toyotas.
Save fuel by using 95 Octane and pump up your tyres a few pounds higher. Empty out your boot of excess weight - all these may help. Enjoy your ride...cheers

that figure looks normal though...

one other tip, Carbonsmilth, if your Sunny is still new, use the Mobil-One Synthetic 0-30 specially formulated for newer engine (Stated on the quart bottle). Definitely will see improvement in FC. I bought some of these at Carefour for $10 per quart. You need 4 quarts. When the engine is older, say over 40000 then you can use thicker oils like 10-50..... cheers

Just curious: how are you measuring your fuel consumption?

fill up full t0 the brim. Drive to whatever distance, doesnt really matter. Record the distance, Go fill up full to the brim again and see how many litres you put in . Then take the travelled km $ divide by the litres used
and there you have it.
Some cars have varying FC with different octane grade, some cars make no difference as long as it meets its min.octane requirement.
Some cars have on-board on-the spot read out of km per litre consumption, so this is more accurate.
But age of car, driving condition, tyre pressure, oil viscocity, air-filter, plugs, your right foot, weight of the car, passengers carried, etc also pay an important part to get optimum FC,
I'm averaging 13.8km per L on my new (5000km driven-in)1.8vvti MPV , using 95Octane, with an occasional heavy-footed driving and carry 2 passengers 30% of the time on 60% highway, 40%urban traffic -
My Sunny FL(M) is coming to 2 years old and I would like to share with you the performance of my car so far:Originally posted by Carbonsmith:Hi Guys

I get an average FC of 14-15km/l. 70% highway 30% urban driving. Aircon low usuage and speed try to keep 80- 90km/hr.Petrol using Shell 95ron. Engine oil Castrol RS.
I have done the following so far:
1) Install Splitfire spark plug.
2) Gounding. (took the combo package with item 1 @ $156)
After a few months,I get a simple Cold Air intake done.
After doing item 1) n 2), FC and performance reach what I have now. I personnaly think gounding is good for older car only.
As for the CAI, I realise it doesn't help much when I keep to 80km/hr. But when I try to go faster @ 90km+, it doesn't have high impact on my FC.
Everything else is original stock. Even my wheels are original steel rim type.
Hope that helps. -
i noticed sunny's rpm is around 3k while crusing at 100km/hr. maybe thats the reason why its FC is pretty poor. i guess u haf to travel at a lower speed if u wanna maintain a gd FC.

i own a nissan 1.5AT for 4 years, initialy e FC was high at @10.5km/l
i install grouding, feul max and ES68 and the C improves to 12km/l
but when i change to hte new nissan N16 1.6AT with the so call improve engine.........but e FC is still 10.5km/l
i install again the ES68, grounding and voltage stablelizer and change the air filter......FC now is 11.4km/l
anyone has more to share on FC
-
Carbonsmith,not a surprise of your FC. my sunny only clock 7km/l.So think how bad it is.

high revs don really mean high consumptionOriginally posted by so_nice:i noticed sunny's rpm is around 3k while crusing at 100km/hr. maybe thats the reason why its FC is pretty poor. i guess u haf to travel at a lower speed if u wanna maintain a gd FC. -
Hi Guys,
Thanks for all your info. Will try to monitor my FC again.
Cheers, -
high rpm is equals to high fc. reason? what is it that causes your engine to rev? its the fuel.
-
btw its 2.5k not 3kOriginally posted by so_nice:i noticed sunny's rpm is around 3k while crusing at 100km/hr. maybe thats the reason why its FC is pretty poor. i guess u haf to travel at a lower speed if u wanna maintain a gd FC.

edit: its a 4 speed car and travel 100km/h at 2700rpm also.. -
i'm not talking about changing gears at a certain RPM. and its certainly not a matter of your mz6 2.0 vs sunny 1.6. i'm talking about the RPM while crusing at a constant speed. if u get what i mean.

Hi, can anyone advise me on how much pressure should I pump for my tyres under my new Nissan Sunny 1.6A?? How much is appropriate for better FC??
(200, 205, 210 or 220??) I am pumping 210 at this moment.......the tyres seems to be abit noisy on highways.......

my nissan sunny is 1.5yrs, 1.6MT. FC is also abt 11km/litre. jus do a simple comparison of the kerb weight of the cars base on the information from the websites of the various brands and u will notice tat ceteris paribus, nissan cars are heavier.
