Auto-LPG Conversion Thread

[daneklog]

In my experience with high tension wires, they tend to fail after a year or so after installation. They either "leak" (failed insulation) or conductor breaks at the sockets by mechanical failure or corrosion.

Stock wires are still better unless you have fully upgraded your engine's ignition system.

What is the color of your spark plugs tip? If your spark plugs have these black deposit, you probably have oily lpg contamination on your tank. The only solution would be bleeding all your lpg out of your tank and change filling station.

Spark plug colors are whitish. Ang naging basis lang sa diagnosis is the used of testers, hindi pumapalo ang reading pagdating sa isang wire.

hinde pa pwede i verify by changing the affected tension wire lang muna from other cars. kasi mahirap naman bumili ng bago then kung hinde mawala ang problem sayang ang pera. mahal pa naman ng high tension wires.

update mo na lang kami sir. thanks.

Why not just use the original wire-set that came with the vehicle to test if the source is the high-tension wires currently in use?

actually that will be our next move para talaga ma-assure na tension wires nga ang pinagmumulan ng problem.

im wondering kasi that i run smooth on gas then when using LPG, tindi ng back fire as in maririnig talaga even inside the advie.

question lang po:
1.0 has anyone tried using resistor type plugs? if yes does it improve your lpg performance?
2.0 how about iridium and other type of spark plug aside from the plugs recommended by OEM. may nakagamit na ba and does it also improve your lpg performance.

reason for the question:
im using lpg for almost 5 months now with stock plugs * 7K km running on lpg. the problem now is when the car is idling without AC, nag ddrop and RPM to the point na mag stall na yung kotse. during the first 3 months naman hinde ganito.

as recommended by greenfuel yesterday (alvin) try to replace the plugs with resistor type or the 6pbs type. i want to check with lpg user first para malaman kung may significant impact ba ito otherwise i will stick with the stock plugs. Thanks.

Resistor plugs are also recommended on any vehicle that has other on-board electronic systems and as a rule, performance is in no way impaired by resistor spark plugs. Best to consult your vehicle specification booklet or search it via Internet.

Toyota Innova stock spark plugs uses (R) resistor type spark plugs (Denso K20HR-U11) because it has OB electronic system. Furthermore, I have been using one step colder Iridium (Denso IKH22 also resistor type) now running more than 10K++ kms with no hesitation and the engine runs a little bit colder too. I see not much difference using Petrol or LPG, but engine runs smoother on LPG

The only consolation of using Iridium and one step colder was extended life of the spark plugs, if you are comfortable with your stock plugs then just replace them shorter than normal schedule.

Just maintain the same type of sparkplug you are currently using and simply change to one step colder.

From what I have been reading, platinum cold sparkplugs seems to solve sparkplug related problems.

LPG prices keep getting higher. So the price difference between LPG and petrol keeps getting smaller. With the high cost of conversion, the ROI is getting longer. It seems it is now harder to convince other people to convert than it was a few years ago.
It is somewhat similar to what happened between diesel and gas. Years ago, their price difference is big, but not now.
You think that would also happen to LPG, that the price difference between LPG and gas would soon catch up to just a few pesos?

It'll get higher, but I don't know if it'll reach diesel-gas levels (and remember, diesel here is artificially cheap due to government subsidy). LPG has diverse sources, and is not reliant upon crude oil production.

The price inflation locally seems artificially induced. We'd been talking about the possibility of hoarding a few days ago, and lo and behold, the government has already caught at least one trader hoarding LPG canisters.

I'm sure there will be many more to follow.

* mile2 &GH : thanks for the advice. will replace the plugs with a step colder, check ko sa suking tindahan. update ko kayo. maraming salamat
