After my 5th tank, Esso 5000, still around 6-6.5km/l. my god

 

cause leaving it in nuetral is as gd as letting the engine idle. this engine drinks more during idling. must make it work for its meal.

 

Renesis SE3P,

Never leave car in neutral going downhill for any stretch of time. You may get brake overheat and even failure and go off the road !

-Ringer-

 

Oh, I see, I thought I was going crazy when my mpg went down quick when in neutral....

 

Yikes, I drive a lot and America is full of mountainous terrain especially when you're traveling from one State to another, every time I hit a downhill section, I always leave it in neutral. I'm going to start leaving it in gear now, I also need to change my brakes too.... thanks for the tip.

 

I generally do 75%-80% highway driving during off-peak hours, and so usually average 8 - 8.5km/l. Best was 8.991 = 9km/l.

At the 1/4 mark it's usually anything from 380km to 400km.

And oh, I'm light-footed as well!

 

what's your car model? 4AT? 6AT? Type S?

 

Anyone currently using fuel saving devices on their 8? How's the FC after that? Great if can share your experience.

Seriously considering one after my 6km/l FC. Not much difference whether I drive light footed or slightly heavy on my 6AT...

 

4AT / 18" Toyo T1R / 33 PSI all round

 

Hi all bros, i am pretty new in this forum, getting my 8 in Sept. I understand that keeping smaller rims enables better FC but Just wondering if keeping a 16/17 inch rim will actually big diff in the FC .

 

My experience with my current 18" tells me there's little or no difference using them; lighter rims lower profile tyres COULD possibly mean less weight and mass, or otherwise just a negligible increase.

I mean, I've yet to hit anything less than 7.5km/l (but I do mostly highway driving!)

 

04 6MT USA 15-19 miles per gallon. normally about 280 miles on a full tank. tank is about 15 gallons.

 

I'm doing around 5.5km/l n heavy footed. Tried to rev less but also not much diff hence I gave up. Might as well just whack lah... haha!

Anyway, i'm 90% city driving so i think 5.5 is still acceptable to me...

 

Thanks for the reply! will be checking out some fuel savings device once i get my 8. Will update bros here if there's anything worth looking at.

 

there isnt any fuel saving device. if there is, power stations would use it to save fuel already. a 10% saving to them is in millions

 

just did my second tank, 445km with 54.3 litres Shell 98. 1 year old 4AT stock. But something strange. I did 250km up to the halfway mark shown on the fuel meter, so that means I only did 195km on the remaining half. Driving profile didnt change much other than slightly poorer FC on a SAT with city driving while doing errands. Perhaps that means what is shown on the fuel meter is not exactly proportional?

 

I suppose its like that...I always get more mileage on my 1st quater tank...

 

All along i thought Fuel tank is from big to small.
The top part is usually larger then the bottom and thus you can drive more distance.
I believe the fuel tank look something similar to a cone.


Anyway i am getting between 6-7km/l.
never rev much. but give up on asking abt petrol anymore.

 

Has anyone used the Octane Booster before? any particular brand? NOS? Snap?

 

don't use octane booster - it does nothing for the renesis

 

About the disproportionate mileage/litre of petrol on the fuel gauge...
The needle drops much faster in the first quater than last quarter for me...
when u drive on a full tank with 60 litre of petrol which is equivalent of 60 kg, the fuel efficiency is poorer than when there is less petrol in the fuel tank after the second half. Hence the fuel efficiency is slightly better in the second half, thus the needle drops slower in second half than the first half...
my 2 cents worth...

 

Actually i noticed that mine is quite proportionate. 70km for 1st quarter mark, 80km for both 2nd and 3rd quarter mark, warning light usually appears ard 260km or 30km into the final quarter and i'll usually drive on for 30km or so before refuelling.

If what you said is true, maybe someone can try topping up to only half tank everytime or even just $20 of fuel daily and share with us if your fuel efficiency improve?

 

Mine really plunge really fast on the last QTR. But its strange that fuel efficiency is higher when u are heavier? It should be the other way round? My first QTR I can do 120-150km, second QTR 100km. third 110km, last one 85km. hmmm?

Another observation, i was stationary on a slope (about 30 deg upwards) and tank was 1/8. within the 1 min I saw the needle go from 1/8 to zero. Cool.. But when got moving again on level ground it bounced back to 1/8. nevertheless still quite a big fluctuation.

 

Has anyone tried the ion accelerator called Calski before on their 8?

 

The calski is damn gd man....i put like 20pcs and my fc went from 7.2km/l to 7.25km/l
