Yes I am. They just have to make a template for my carb on Saturday. Quote was for 25-28k. I drove their Optra.... I was convinced!

may contact number na din ito baka gusto nyo kalabanin ang NAIADSS ahahahah

chua ed:

nakausap ko si weng rowena ng naiadss she tells me the 60 liter tank capacity is really only 48 liters

how come you were able to fill in up to 50 plus liters into your tank??

1979,

Ang mura ng quote sa iyo. I hope they can lower the price to 25K so I won't have to choose between the one in Pioneer and AmbiEnt. By the way, will they fabricate the mixer for your carb or they'll order it from Italy? They don't have a mixer for my car in stock so it will take a week for the part to arrive.

These are shots of my trunk with the fabricated cover for the LPG tank.

I hope they stay with their price. No, they won't fabricate and the part arrives in 5 days, so they say. Let's see.............

pareng Chuaed:

baga may leak ang system mo kaya matakaw din pa check mo kay MR. Yu yan yung medyo matangkad na koreano magaling din yun at medyo marunong mag english yun. it shouldnt get more than 51 ang full tank ko talga is just 40 plus liters after that wala na

Gud pm! newbie here. Just came for the autogas talk since i'm a newbie there too. My 1999 KIA Pride GTX was converted by NAIADS last March. It has been all that I hoped it would be.

Am particularly impressed by low-end torque, smooth and quiet operation, clean engine and exhaust, clean oil and power.

am also more aware of limitations and imperfections of the "conversion" process being at best a bi-fuel compromise.

I think autogas is ideal green fuel but I think we have to use an "autogas engine" to get the most out of it.

Hope to hear more about your experiences driving on gas!

Cheers!

im new here and would just like to share what i know or rather experienced with the LPG conversion kit. im a taxi operator with my dad and mostly use the Macro LPG conversion kit. (italy brand)

as compared to the naiadss lpg kit, i find that it's harder to maintain rather than using the macro lpg kit. however, both are fuel cost efficient.

a typical taxi driver would drive around 400kms per day and would usually consume P1.2k worth of LPG. around the time when we last used gasoline price was about P44/L for premium and most drivers would atleast consume about P1.8-2K/day.

so it was a big difference for the drivers since they'd save about 600/day. that almost concluded to be what is advantageous for taxi operators like me since taxi drivers would come applying to you becoz you use LPG.

then came the maintainance. running your car on LPG especially on this hot summer was unspeakable. im only speaking for taxis btw. a lot of operators and machine shop owners know of the hazards a lpg does to your engine.

compared with gasoline, when gasoline evaporates on your hand, u'd feel there is lubricant left. whereas with the lpg, after it evaporates, it's almost gone completely aside from the smell. having that in mind, the lpg wasnt intended for your gasoline engine (having said that there is no/not enough (if any) lubricant in the lpg). which i think would result in higher temps. im not entirely accurate about why it has higher temp but that was just a theory i came up with. but that's definitely what i came across having a LPG conversion kit on the taxis.

since private cars run typically less than 150kms, i guess it's ok. but that's up for you to decide. personally, i dont like the idea of a tank in my trunk and the idea that its not engine friendly. it's not a perfect conversion. im hopeful that a better conversion kit will come up.

Ei! Dencio! thanks for your insight from the taxi operators point of view...though I believe your overheating problems are less LPG-related than it is the usually inadequate vehicle maintenance of local taxis fleets (though I noticed D'Avis seems better maintained than most.)

If you check out all the links I sent in a previous post you will find that LPG is particularly "engine-friendly" though I don't believe it will improve a poorly maintained or defective engine!

maybe you can mention some of those hazards? The summer in Australia is even hotter than here, reaching over 40C, yet, its fine to use LPG powered vehicles there. Some are even fitted straight from the factory to run on LPG.

compared with gasoline, when gasoline evaporates on your hand, u'd feel there is lubricant left. whereas with the lpg, after it evaporates, it's almost gone completely aside from the smell. having that in mind, the lpg wasnt intended for your gasoline engine (having said that there is no/not enough (if any) lubricant in the lpg). which i think would result in higher temps. im not entirely accurate about why it has higher temp but that was just a theory i came up with. but that's definitely what i came across having a LPG conversion kit on the taxis.

Gasoline burns hotter than LPG. That is the reason why an engine running on LPG is cooler than when it is running on gasoline.

Also, engine lubrication for a four stroke engine, comes from the motor oil, not from the fuel.

since private cars run typically less than 150kms, i guess it's ok. but that's up for you to decide. personally, i dont like the idea of a tank in my trunk and the idea that its not engine friendly. it's not a perfect conversion. im hopeful that a better conversion kit will come up.

The best conversions for LPG would require a higher compression ratio and adjusted (more advanced) ignition timing. But that would mean the engine will NOT run on gasoline anymore. Given we don't have an extensive number of Auto-LPG filling stations yet, a LPG dedicated car is not yet practical.

In the end, its still your personal choice if you want to save some money in the long run with Auto-LPG or staying with your belief that gasoline is better even if you have to pay a third more for the same liter of fuel.

Myself and a few other guys here have converted our rides to LPG and we all haven't encountered problems beyond basic engine maintenance issues.

[dencio1976]

what i gave was input from my end. im not to discourage private car users using lpg kit conversion. like i said, taxis drive on an average of 400kms a day. private cars probably less than a hundred. this leads me to conclude that it almost wont affect the private cars the way it does taxis in general.

and i would have to agree that it's not all the lpg's doing that it overheats. it also depends on the driver and maintainance. i was simply saying that it does more than having gasoline on a gasoline intended engine.

im not saying anything bad about the lpg itself. after all its much safer to the environment. also that there are cars that run on lpg out of the factory. which are great. also that they(Macro) have this new type of lpg kit that has a control unit that comes along with it for fuel injected vehicles. more expensive than your regular kit however more effective. but with the tank still in the trunk, id still want an lpg car with an engine intended for lpg. im not too sure but japan uses lpg cars. that may be the typical lpg car that id want instead.

hazards are all typically overheating related. from hardened oil seals, blown head gaskets to busted engine parts like the exhaust valves even. never had a busted cylinder head thou but i hear there's a case like that.

id have to agree that d'avis is one of the best maintained taxis along with toyota alabang. but even their maintainance department would have to agree.

heck even guys from macro agrees with me. im not too sure with the naiadss guys thou.

why not have inputs from d'avis? try your research with them. and prove me wrong after.

oh and also, it's not only the engine parts that need lubrication. you also need lubrication for your combustion chamber. that's why lpg guys recommend that you run your cars atleast once a month with gasoline.

Dencio, actually the combustion area needs no lubrication at all. Any lubrication in that area would result in more smoke and would increase pollutants in the exhaust pipe. Only two stroke engines receive oil in the combustion chamber.

Besideds, all engines after 1992 are already designed to run without lead sulfides in the fuel (thus "unleaded fuel") and do not depend on the fuel for "partial" lubrication. You are arguing on a myth.

please read a bit more on fuel theory and practice so you can distinguish urban legend and opinion from facts. Tom Jennings article is a practical and scientific analysis, and would be quite informative for any machine head who wanted the facts, check it out at:

with these basics you might be able to explain why your taxis do what they do!

cheers!

regarding this point, isn't it more that the gasoline in the fuel system will not "stagnate" than lubrication?
