bosch super 4? well i'm using it right now... i think the only problem with these plugs is that if it fails.. you dun know it... i've been plagued by slightly higher than normal consumption for the past month or so and also difficult starts and frequent engine mati... sometimes can hear the car sputtering on three cylinders... so i suspect that one of the plugs is firing inconsistently thereby causing a reduction in power and response and also causing a bad jerk occasionally due to the inconsistent combustion...

when i change... i'm gonna go for the 2 or 3-pin Valeo plugs... i think these are the most recommended by the members and i think is rather the best... i should have these plugs in my car by end of next week...

>>>Heretic, i think the bosch type plugs are not impedance matched to the rest of the ignition system supposedly by magnetti marelli or valeo. Though they may work finer details would bad and could really be damaging sometimes. I would just stick to valeo for these reasons.

cheers

Hi all,

Just did a massive re-do on the car. Engine flush, changed engine oil,
gear oil, oil filter, plugs, timing belt + bearings, alternator belt,
drained, cleaned container,bled and changed power steering oil, re-
alligned my front bumper, re-alligned my dashboard and changed petrol
filter. Cost was about RM600 but well worth it. The funny bit was when the
mechanic took out my petrol filter, he asked me sarcastically what petrol
I used. I told him Shell and he emptied the contents on the filter on the
floor. I think the previous owner never changed it cos all I saw was
sediments flowing out. It was black as hell. After this re-do, I'm getting
about 350km per tank, with quite an amount of power tests on the road. I
would say it's much better now. Quite confident I could get 400km with
normal driving.

Just to check, is the pricing expensive or reasonable?

sounds reasonably cheap... or rather, sounds very cheap

[dereklaw]

My consumption is roughly 400km for about RM50, plus or minus, depending
on the traffic situation. I have asked around and its quite good for a 2
litre car. Its definately better than my colleagues Waja 1.6 (A), with
RM50 can only get 300+ km.

heretic...regarding your filter situation... make sure you dun use V-
power...

also another thing is that i recommend that you get your fuel filter
changed at within the next two oil changes... this is because the old fuel
filter would have left sediment within the fuel tank itself due to the
lack of maintenance by the previous owner... so now that it's being
cleaned... and filtered properly... the new filter would dirty rather
quickly as well... i suffered from a similar fate and when the second
filter was changed... there was black sediment as well...i still on my
third one... but will probably change it soon...

consumption for the ZX is reasonable... but you have to remember that you
should compare the Auto with and Auto's consumtion... derek... i'm not
sure whether yours is an auto or not... but if you get 400+ it's
commendable... but in fact the 2.0i can do far better if well taken care
of... i haven't heard of the ZX 1.9is doing very well in terms of
consumption but then again... they are usually being driven hard and
fast... my filling this morning was around RM38 310+kms... that's pretty
good... it's mixed driving of course... kesas and town... about 1/2hr jam
everyday... so... that's what i get... am i correct in stating that it's
about 12sen/per km? dunno how to really calculate this...

[rfbu]

vonnig... it's very easy to count, I count it like this:

310km for RM38 or 3800sen

hence,

1km( i.e. 310 divided by 310 ) is

3800 sen divided by 310 km = 12.5 sen / km

u knew this right!!?!?!

to check, 12.5 sen multiply by 310(because there're 310 km, and each km
costs 12.5 sen) is about RM38

[vonnig]

hahaha... i still suck at my maths... ... well.. i'll go figure... i
guess i got it approx right ler...

[puginfo]

>>>$38 for 310kms is surely good as compared to mine doing $48 for 310kms.
I usually change gears at 3000rpm and try & maint. What about measurement
method? You check every fuel tank top up till the max? When do you start
topping up again, which min mark do you use?

I have not seen better than 8-9kms/ltr on this engine yet.I'm currently
working on the ignition part to see if makes any diff.

Cheers

i usually refill at the quarter mark... my meter stays on full until
almost 120km then it drops to the 3/4 mark... after which the drop
continues at an accelerated rate... by 230kms it's slightly below the
half mark and by 300km it's almost at the quarter mark... usually i'd
push on to slightly below the quarter mark... depending on whether it can
coincide with my usual filling time which is early in the morning...
cooler air less evaporation... (i wonder if this is a myth but it seems
to work better than when i fill up during hot afternoons)...

i'm now pretty light on the throttle... but an occasional rev or so up to
140km/h during the last filling was ok... i therefore think that i could
still get better mileage off this if i drove highly conservatively...
ie... no more than 100km/h but above 80km/h
