Yeap, Done my 1st 1K service last week and it doesnt help at all...

Now my full tank can only bring me up to 320 to 350KM only... Not sure why so bad..

Usually 60% highway and 40% city driving..

grippier tyres = Michelin PS3. i drove 3km down the road to my regular tyre shop and traded the stocks in the very hour i got my car. my City is the VTEC one. it's not exactly that efficient but still doing better. btw, mine is a FLX SE (CVT). so, there's nothing really to do except hit the accelerator or lift off.

I normally fill up when the warning light comes on. At that point about 29-30 litres will fit in the tank. Don't think I've pumped with one solid bar remaining before. Bear in mind that as pointed out above, only about 36 litres is usable. After many tanks you will know how far to push the warning light while preserving a safe reserve amount. When the nozzle trips, the tank isn't quite full, often you can fit another 2-3 litres by gently squeezing the nozzle lever gently repeatedly until the fuel nearly overflows.

Okay, about the fuel pump. Yes the fuel pump dissipates heat into the fuel as the pump is submerged in the fuel. When the warning light comes on there is still a substantial quantity of fuel left. The best way to find out is to take out the Gaga fuel tank, cut off the top part, fill just enough fuel to make the warning light disappear and see how much of the fuel pump is immersed. I don't believe the fuel pump is so fragile till the tank must always be at least half full. I've been doing this for two years and nobody here has reported a fuel pump failure. By not using the full capacity of the tank you drastically reduce the range of each tank (consumption doesn't change). I don't like filling up at the petrol station for three reasons. You have to handle the dirty nozzles, you breathe in the poisonous vapours and you expose yourself to robbery and car jacking. I'd rather run my tank low and fill up less often.

Hm.. Not sure what's the problem, but have you checked your tyre pressure? From what I know, cars that are being collected often run too high a tyre pressure, I can't say much on the highway/city drive coz a mixed drive, you can't always get similar results, traffic jams might occur and stuff like that.

Ah.. No wonder, that was my initial plan as well but I've decided to just use the stock tyres while I hunt for a set of Japanese wheels before changing the tyres together. Well.. Anyway, what I meant in terms of "driving like a manual" is the throttle input. I'm not so sure if you had driven a manual, but, sorta, in a sense, you rarely take your foot off the throttle, merely using the throttle to control the acceleration and deceleration. Driving it like an auto will mean you'll be stepping on the brakes and throttle heavily far too often than needed. Never driven a City VTEC so I can't comment on the FC, but the Jazz iDSi in my family is helluva decent FC car.

that's how i usually drive... the CVTs for both cars have a decent amount of engine braking so, stepping on brakes are not really necessary. in fact, i get annoyed when people step on the brakes for no good reason

Yes, I totally understand that it doesn't fully fill up even when the nozzle trips, sometimes, it trips as the displacement of air inside the tank triggers it. As for the fuel, it's not due to the overheating, as you mentioned, more like due to the impurities in the tank being sucked up(especially when your car grows older) as the fuel filter is AFTER the pump but BEFORE reaching the fuel rail, and also the possibility of pumping dry when your take corners.

Frankly, 2 years is not a very long time for the fuel pump to start showing signs of failure, give it 5 years or so, then we start talking, but, heck, I know most people changed their cars before the fuel pump even died. I never made any indication that the fuel tank needs to be always half full, I just merely mention that it's not advisable to let it run until the fuel warning lights comes on every single time. It's just my habit of refuelling before reaching 1/4 tankful. I would refrain to comment on your reasons, to each of our own reasons.

I used to get about 400-450 km on one tank, driving around KL and PJ. Occasionally a bit more. Unlike most people I don't really get caught in bad jams, that's why. My record is 546 km on one tank. I can't analyse your chart for now, on my phone.

Well.. I guess there's nothing wrong with the driving then. I can't comment much as I hadn't even touched 1k mileage on mine, and I'm running on them shitty stockies for tyres.

That's a very good point about the filter being after the pump. I accept that there may be sediments at the bottom of the tank which may be sucked by the pump when the level is low. I wasn't really referring to you about the tank being always at least half full, as you posted some more stuff while I was typing my reply. It was more towards the general habit that some people have.

Like you I am peeved about the small tank. It should be at least 50 litres, but maybe there's not enough space to fit one.

I got a question. Saga FLX CVT L mode is Low Gear or Sport Mode?
What use for it?

Well.. The pump is a submerged in-tank unit on most EFi fuel tanks, and the fuel filter is almost always after it, but before the fuel rail(where it's supposed to filter out most, or rather ALL sediments to prevent it from clogging up the injectors), hence my mention of NOT frequently running dry, or almost dry. Unless it's been modified to run an external pump where you could fit a high flow filter before it(which my now-no-longer-daily car is setup), the recommendation is still to refuel before it hits warning at best.

Yeah.. It would had been great if it had 45 or 50 litres, but I supposed as it's based on the Savvy platform, it's probably due to the lack of space to fit a larger one. One of the bigger peeves I had about it, others are pretty minor like the lack of a one-touch power window for the driver's window, lack of factory brake lock etc.

Another thing I've encountered, but I suppose this relates to the CVT owners only. Do you guys find that shifting from L to D, it nudges into N momentarily? Mine does and it kinda annoys me, not that I find the need for L-gear yet.

It's supposed to be Low Gear instead of Sports Mode(like the Preve CFE Premium).

Engine Braking...

One thing I no longer have. XD

Engine Braking what mean?

go drive your car to a slope

when going down slope, release your foot of the throttle. Dont press any brakes unless necessary.

you'll notice the engine will start to rev @ 2,500rpm and your speed gradually dropping. Itulah engine braking.

Added on July 25, 2012, 12:01 amneed to adjust. coz not very use to the tightness of the shifter. Sometimes we will input more than required amount of energy when shifting from L to D and that makes it jumps to N. I always practice it when idling before really dare to tarik from D to L then back to D. The point is not to much, nor too little. Adequate.

oic... mean is low gear lo?

DUDA, fairly reasonable lar. I've been suffering for 30 tanks before I reach 400km/tank, provided that is after ma kar being "touched" by lhwj

Errr... I used to dieded a few fuel pump on different vehicles, normally AFTER tank being sucked dried The worst case I had was 1 of my imported car(can't remember what car/model is it ady), the ranjiao fuel pump is INSIDE the blardy tank! We had to take out the entire tank, open it up to fix the pump. So, since we need to open the tank, we get to see what is inside... so damn much of residue in the tank continue we grind open the koyaked fuel pump, all those rubbish was stucked inside the fuel pump that causes it dieded.

So, we(with my magicians) had an argument in the workshop for days/weeks/months/years/decades until recently I went back Ipoh talked about my GaGa's bad FC, the fuel pump KO issue still in argument. Below is our supporting fact, you make your own decision.

1) Whatever rubbish we pumped in, it will still flow inside the tank and get sucked by the fuel pump. So, be it fuel up at the most top of the brim every 1/2 tank, your fuel pump still die
2) Normally fuel pump didn't do any filtration, its the fuel filter that does it. However, fuel pump 1st, then fuel filter, that's why if those object stuck in the fuel pump, in the logrun it became blood clog, then heart attack liao.
3) Dares + Grexer type of saying, always keep the tank atleast half full to make sure nothing float to the fuel pump

Our unsettled conclusion is, regardless how bad it harm with considering the above facts, my fuel pumps always died"ed" after tank being dried. So, don't let it totally dried.

Well.. I have to again, clarify that I never mentioned anything about always keeping the tank at least half full, I mentioned to NOT always run until the fuel warning comes up with the probability of running dry. It's always a known fact that any liquid pump is not meant to run dry a.k.a. pump air. Only air pumps could survive doing that.

Fact: Trying to NOT ever run your fuel tank dry as it'll kill the fuel pump sooner or later.

I've never experienced the fuel warning yet. Whenever it comes to 1 bar, I feel nervous and straight away find petrol station

Soli, unker type sloe, I already saw your latest reply

p/s: Soon dares is coming to shoot ady," I where got say half tank refuel "

I see. And I suppose putting the filter before the pump would create too much resistance for the pump? Or is it the inconvenience of the restricted access when the filter needs to be changed?

I'm okay with the lack of one-touch power window. Brake lock is easily installed so that's not a prob. I'm the kind who likes to use their wipers as little as possible, even to the extent of turning them off when I wait at traffic lights, so the lack of a single wipe function (push stalk upwards to wipe once) and variable intermittent speed control is kinda annoying. Also, there should be a clearer indicator that the rear demister switch is on. I tend to turn it on then forget about it until much later. Cruise control would be nice for long distance highway driving, but I guess that's asking for too much in an entry level model

I've been throughly enjoying my Gaga these past two days, chalking up about 150 km cos being in Penang the roads and corners are really familiar, and now that I'm back the difference made by the FSB is more apparent compared to in KL/PJ where I drive less hard.

Actually I've realised, there are lots of good driving roads in Penang. The Tanjung Bungah - Batu Ferringhi - Teluk Bahang stretch is great, provided you don't get stuck behind a slowpoke. Just drove on it in the morning as I went hiking at the national park. Another nice one is the road between Batu Maung (at the end of the TLCE highway) and Bayan Lepas, which goes across the southern end of the airport runway. I used to use that road every day after work to avoid the jam in the Bayan Baru area. As for the Teluk Bahang - Balik Pulau - Teluk Kumbar stretch, I will try it soon, within the next few days. Gotta bring my friend sightseeing.
