How do you manage can you give your secret. i also have lmst 2004 and how to record km/l fuel consumption :/

saga lmst cannot achieve this mileage..so nonsense la..at most between 10km to 12km per little.old car where got fuel saving.

I enjoy driving...so I don't worry about fc... but since I know the "secret to good fc" , my fast launching and higher speed don't sap my fc too much... hahaha

idea being extra fuel burn in the short launch is offset by low fc during the longer drive... so must depends on situation

Fast launch and higher speed dont sap my fc much

Tbh, fuel consumption not much difference between speed. Lets say someone cruise 80kmh with someone cruise 100kmh.

The main culprit is acceleration. that is why cannot launch fast fast. Yeah, I met a lot people like u, fast launch then long driver hope the fc will be efficient. its not.

if u got fc reading on dashboard, u try drive
1) 2k rpm, then cruise 100kmh
2) 4krpm, then cruise 80kmh.

I had try above method and Option 1 is more fuel efficient. But option 1 cannot be follow by someone who easily butthurt at traffic light and want to win drag race like what 90% malaysian driver are.

I dunno why, the option 2 just dont work. Maybe too much fuel burning during that short period of times.

On most cars they have Instant FC meters for the driver to gently press as light as possible.
Though it needs more eyes and "concentration" on the meter to get the "lowest" FC reading possible.

No need to glance so frequently la bro..sometimes also can..the most important is rights leg is consistent.

fast launch doesn't mean burn rubber lah... aiyoh taken out of context a bit...hahaha... np

i meant fast/steady acceleration to cruising speed... so move through the gears quickly but do so without over rev, without dragging, or lugging when shifting up, is the key. 4k maybe over rev a bit that's why your fc suffer

anyways, most of the time i can meet manufacturers mileage claims...so i know i'm doing it right... also high speed do sap fuel...my cars have fuel meter so i know for sure
*
Cruising speed is the most efficient phase in any car..We use company car, my kolik drive at middle lane between 100kmh to 120kmh, but when times comes to overtake middle lane, he always rev, overtake then enter into middle lane back.kek. While me drive consistent 140kmh, very minimal rev. Even no use brakes, just let off from throttle if find slow cars.

U guess what, my driving style more economical.lol.

High speed may sap fuel, but its not as damaging as people think. But I do see if people drive fast they like brake hard when approaching slower cars then rev acceleration like mad want to achieve back high speed.

Its like high speed cruise but steady vs high speed but rough, got a lot of difference.

U cant have a cake and eat its too..at traffic light, even bmw 330i will lose to honda city if city do full throttle and 330i do partial throttle..

what I do is, usually will maintain 2500rpm, lets car beside fly to the moon then later usually will overtake them. most of them I see, drive slow later with the hope to save fuel, but fuel burn kaw kaw at the beginning they dont realize/care.kek.

you're complicating the issue.... constant 140 will use more gas than constant 100... for sure

and erratic driving style will hurt fc...as you know
*
Not far dude..100 can be as high as 140 if rough driving which is habit for malaysian.

it's not as simple as modern turbo + dct... it's all about matching engine power/torque with good gear ratios for the weight+load of the car

I drove a 3.5L NA, normal 6 speed auto, 2000kg 8 seater once, and it does better than your 9.5km/l...
*
Both drive 170kmh, but one accelerate madly from 110kmh to 170kmh, while another accelerate gently from 110kmh to 170kmh. Both will get very different fc reading.

And as always, u will disagree with me. Sometimes its really hard for someone to accept other people opinion rights.lol.
