Hi,

Can I pls have your expereince on below situation?

Recently I did my petrol car (2005 model) throttle body + injector (manual cleanup not that can stuff) cleanup and replaced s-plugs with platinum plugs. Reason to do all that was, I used to get 15+km/ltr km/ltr but it dropped about by 3km/l. After doing all above it has gained about 1.5km/ltr. Car pulls smoothly. Any caused why it didn't get to original status.

Thanks,

Sorry I seem to have miscommunicated it. It should be read as original 15+, dropped to 12.5, then after repairs got 13.5+.

Hi Nevile

That is embarrassing ,fuel consumption to fall from 15KMPL to 3 and then to 1.5 KMPL

actually the mechanic has not identified the real problem on it he might have thought

throttle body + injector cleaning would solve it, but not that you might have any other problem or either he

has not done the job properly.go to a good mechanic mate.

Thanks

Thanks Sumith. I miscommunicated the pciture. It is like this...original 15+, dropped to 12.5, after repairs 13.5.

If you are getting 13.5km per Litre.. on a petrol car.... you should be happy...

exactly

btw Neville....what's the car you drive?

those are very impressive figures!

and also...have you replaced the air filter? that clogged filter can affect fuel burn quite a bit

That's a serious possibility lol, once I had to replace a leaking fuel line hose, which has been leaking for sometime

You might also want to check on replacing the Fuel Filters as well - Generally there is one in the tank and one in the Throttle Body unit depending on what Car your driving...

Hi,

I just want to share my expereince on this matter. Finally I manage to bring my km/ltr back to its original status. In my post, I mentioned that I replaced old s-plugs with platimum (B**h) set. As I could not find any other cause to km/ltr drop aftger doing all that I took the car to agent (Toyota), and they did all checks (by their intelligent scanner) -nothing was wrong and all readings were as it supposed to be. But the service advisor sugessted to replace the platimum s-plugs with what is recommended by Toyota (Denso normal plugs), as the heat range is different (mind you my earlier mech. referred the conversion table -from Denso to B**h...not at all to say the latter is bad, ok) in what I had put. So, it seems that even if the conversion table is referred, this particular property of the s-plug was affecting the km/lt.

Rgds,

Goes to show that it's always better to stick to manufacturer specs.

so what's the car? under what driving conditions does it return 15 kmpl?

[topgear]

I have this feeling you're one of those guys who doesn't rev more than 2000rpm! ...which is actually not a bad thing since you're getting awesome fuel figures.

[Rebel]

So which Toyota is this??

It was Rs.4000+, and the normal s-plugs are about Rs. 450 each.

It is none other than an Allion

Well my driving habits are very sober...if I may say so...I belong to the community who who does not race nor do sudden deep acceleration...etc

Yes you are correct. Why should (or how could we) use more than even 1500rpm on our roads. If done, it will only make you break frequently. There are lot to learn on 'how to drive your car' <img src="style_emoticons/<#EMO_DIR#>/wink.gif" style="vertical-align:middle" emoid="" border="0" alt="wink.gif" /> . The only time you may drive 2000+rpm is on inside the country outstaiton, when road is empty.

hmmm.. very conservertive if i may add... 1500 RPM.. man i exceed that in my drive way...

why should we use more than 1500 rpm? To get to where we're going quicker and not hold up the rest of the road. (especially if, as in my case, your daily driver is an old diesel truck)

How could we do this? By pressing that thing called the "Accelarator" a bit further forward than a quarter inch of it's travel... Don't worry, it won't break!

Thanks for educating us on how and where we "May" or "may Not" drive. Im sure all of us are feeling very enlightened by this

[charitha19]

and another thing mr.nevile.. when u are driving at that pace.. i hope to god u are on the left side of the road.. if you are one of those people thank u sir.. and u can merrily go at 40KMPH and no one will bother u.. i hope..

but pray to god if u are hogging the road and using the right side of the road for ur antics... i will defa sweep u to the left.. i hate buggers who drive like thier car is broken and hog the right side...

At times I wonder why some people bother buying cars at all.... they are better off with a bicycle with a small basket on the handle.

[Neville]

I noted some 'intersting' comments coming out on my attempt to share the expereince.

So, if I have hurt anyone, sorry about it, but here is what my driving exepreinces are:

1. In the morning when I start driving rpm goes around 2500+ at 60km/hr until engine hits the right temperatur

2. Once engine hit the right temperature, 60km/hr works with 1200+rpm (in my car)

3. Our road speed limits (as I know), 60km in built-up areas, and 70km/hr in other areas. I maitian this all the time -if not an emergency -then I would use emergency (hazard) lights.

4. I wish I could drive on left track, but alas ! they are occupied by all sorts of road users who travel 1km - <60km/hr range

5. While maintaining the given road rules, if anyone ask the way, I quickly give with safety in mind

That's all I got to say...any other comments after this...you can enjoy.

Bye,

[Pericles]

In my case, coz my idle is at 1100 and if I change at 1500, it'll drop too low and make the car shudder.

And quite frankly even if you are puttering around at 1500 unless you stay on the 1st and 2nd the whole journey, you still need to brake frequently. I know, coz I tend to putter around at 1500 on the 5th.
