ROI for RAV4 is 21k - Nakakasave na ako ng 6,467.70 pesos
ROI for Outlander is 39k - 9,832.65 pesos pa para makuha ko yung ROI.

Guys,

I do not know if it is related to LPG driven cars.

I have replaced both cars their Valve Cover Gasket and Spark Plug Seal. I replaced them because a leak was visible on the engine.

Outy cost: Valve cover gasket 500 + spark plug seal 1000 + labor 470 - TOTAL: 1,970 pesos - March 21
Rav cost : Valve cover gasket 480 + spark plug seal 600 + labor 600 - TOTAL: 1,680 pesos - March 30

The mechanic told me that LPG is hotter than Unleaded, kaya mas nagiging brittle raw yung mga gasket and seals. If you experience this also, i guess its true...

Any comment?

ako estimate ko by the end of this year ang ROI. ayos talaga.

about the valve cover. nagpa change oil ako last weekend and i also observed the same thing. hinde naman totally valve cover but yung isang turnillo lang. 140pesos and isa. i will observe again kung meron pang nagpapawis. Thanks for the inputs.

Good day TSIKOTEERS!!!!

Sir GH Good day!

Big Mike (Tukayo) I've met Warren and Lorna sa AFCAP already....

FYI lang mga sirs,

I am no longer connected with EROOM Auto LPG Conversion and have stopped to do the business. But for those whom I have installed kits and have warranty and tunning issues please do not hesitate to bring their vehicles sa COOLMATE. Just look for Mang Boy and he will surely entertain you. or you can still call me at 0922888-6453

I am now connected with ECONOGAS Technology Inc. here in G. Araneta Avenue, Brgy. Talayan. We are using a whole new generation of SGI Systems. This system are already Toyota Philippines accredited and is dyno garanteed (autoplus) that power loss in city or highway driving is at most 2% or in some vehicles 0%. Our main line is the VOGAS plus system (dual core processor) and the VOGAS SPlit Fuel System.

Should anyone would liek to know more PM nyo lang me mga sir....salamat...

[samsung]

bigfootoz,

may vehicle system is vogas split and am using 20% petro and 80% lpg.

hmmm... kilala kita

Kamusta mga LPG users? so far 99% of the time LPG pa rin ang gamit ko. maganda naging improvement when i change my plug a step colder, until now naka isang linis lang ang ginawa ko (wire wire brush) FC is around 7-10km/lpg depende sa traffic conditions.

pansin ko lang parang madalas nagkaka leak sa tank fittings, naka dalawang adjust na ang greenfuel dito pero parang dun lagi nag leleak. possible cause ba nito yung pag refill ko, coz napansin ko pag tinatangal yung lpg nozzle sa filler ko, ang lakas ng pressure. My filler tip nga pala ay nasa ilalim ng rear bumper kaya wala talagang support maliban sa kinabit ng flat metal bar.

anu ba magandang gawin dito? any suggestions? ayaw ko kasing i relocate sa lagayan ng gas kasi magbubutas pa.

good day sa inyong lahat!!

So far all except one of the greenfuel installations are running fine.

The only one that had problems was the Mazda3. It required retuning about every month. In the end, the kit was removed (about a month ago) and transferred to my brother's 2nd gen CRV.

which tank fitting is always leaking? the filler?

I presume that you always put your tank as full tank because you are able to measure fuel mileage...

When filling up our lpg tank at full tank, there is a part when the lpg socket starts vibrating violently, It think this occurs when we are at about 60% full (because a full tank is acutally just about 80% full tank to leave space for air). This vibration could be part of the culprit causing your leak. I would suggest not putting your tank at full tank but to refill with smaller portions instead. This may also reduce the pressure inside your tank which as you suspect could also be another factor to the leak.

I need to verify again if it is from filler to tank or tank to vaporiser. thanks.

Thanks for your input. yes i usually fill my tank to the brim kasi to know roughly my FC if normal or abnormal based sa mga trips ko. for experiment i will try your suggestion next week by not stressing the tank and the gas line and see kung may mapapansin pa akong leak.

cheers!!

nag check ako kanina at nakita ko rin kung saan nangagaling yung leak. its coming from the solenoid valve area attached to the tank at hinde galing sa tube fittings. ang problema maski naka off ang sasakyan nag leleak pa rin. kailangan madala sa greenfuel ito at sayang ang nagleleak na lpg at naaamoy ko rin sa loob ng sasakyan.

wala pang isang taon ang kit ko ito na naman ang sira, ung una nagpalot ng vaporiser ngayon ito naman. hay.

Normal lang naman na malakas ang pressure pag tinanggal ang Filler Gun sa filler port. Kahit di ka magfull-tank malakas parin ang pressure pag tinanggal ang filler gun dahil doon sa filler port mayroong check valve (one way), and then pagdating sa tank multivalve mayroon na namang check valve. Yung pressure from tank check valve hanggang filler port check valve yun ang malakas ang pressure pag tinatanggal ang filler gun. Kahit mag-leak from filler port hanggang sa tubo papuntang tank di pa rin sisingaw ang tank dahil merong check valve doon. Actually puede mong pasingawin yung natitira sa filler port hanggang tubo papuntang tank, yun lang ang sisingaw pero di na sisingaw ang nasa tank.

Also, pag mahaba yung thread ng filler cap mo sisingaw yung LPG kasi tatamaan ng thread yung release button ng check valve, pero ang sisingaw lang ay yung na nasa tubo papuntang tank, yun lang natitira sa tubo ang sisingaw pero di na sisingaw yung nasa tank dahil may check valve na doon.

Kung gusto mong magmeasure ng LPG FC, always fill up on the same station and the same pump. Sa Total North Fairview ganyan ang ginagawa ko, kaya parating more or less 10 liters ang consumption ko daily.

Buti nakita mo agad Sandali lang naman palitan yan sa GreenFuel, ubusin mo muna laman ng tank at magtira ka lang ng kaunti, para makita nila ang singaw.

Yung sa akin mahirap makita pag naleak sa multivalve kasi naka-mount sa ilalim ng sasakyan yung tank ko at yung tank cover naiipit ng car flooring.

Nice photo of the leak! I think its the Plunger's O-ring baka naging brittle na overtime. the function of the solenoid is to open the plunger to deliver LPG to the Vaporizer upfront. Either O-ring yan or sira na mismo Plunger mo kaya Passing na LPG. Meaning hindi na sya nagsasara kahit walang koryente Solenoid mo.

As for the leak...it should be contained within your gas box and should exhaust out of your car through the vent hoses. Unless its a major leak it should not enter your car.

Hi Sir, This should not be the case on properly installed systems and ECE67:01 Multivalves. If everything is installed properly the pressure while filling up wont have any problems. As long as you fill up your car at around 80-85% you should be ok.

Yup! This is good advise sir Mile2. This is effective in measuring FC. Also pls. be wary of stations that have uncalibrated dispensers as well. Uncalibrated dispensers can give you an impression that you are filling up more than 80%. for example a normal 60 liter tank should only be filled from 48-52 liters. If on a certain station it goes to 58 or close to 60 that means that station is pumping in less LPG than it should.

Yes, that was my experience with other filling station, if they fill my tank above 80% I never go back to that station again. Other known stations have pumps than do gunning effect on the tank, it fills like 1..2..3 and done!

Right now, I'm settled with Total North Fairview even if their price per liter is a little over than those known stations, It is my impression that their pump is the most accurate and the most slowest filling rate I ever encountered. Kaya pag nagpapafull tank ako dito inaabot minsan ng 10mins...hehehe pero okay lang at least I know eksato ang kinakarga nila. and the most imprtant of all, I do not get oily LPG contamination.

thanks, taken from a camera phone pa yan hehe, i always have the impression na pag switch off ang engine mamatay lahat ng leak sa lpg since it was design to have check valve etc, kaya nagulat talaga ako kahapon when i was observing the leak after switching off the engine, kaya ito kailangan ko na naman dayuhin ang greenfuel to fix this.

siguro nga major leak na ito kasi naghahalo ang amoy ng car freshener at lpg, di maganda kaya i always roll down the windows from time to time para mawala yung smell.

yup i always fill up on one station (total alabang) last time i suspected their pump was not calibrated kasi umaabot ng 32-34 liters, pero ngayon hinde na lumalagpas ng 25li ang full tank. pwede na rin.

sa dinami dami ng check valves hinde pala niya macacapture pag ito na ang bumigay. with engine on or off im leaking lpg. so mag iimprove pa pala ang FC once i have this fix by greenfuel. planning to go there next weekend. Thanks.

Kinda ironic a luxury car having LPG. I guess the previous owner just wanted to buy things beyond his means yun pala nahirapan sa gas bills ayun nag pa-LPG...

Nope. It just means the owner was being practical in converting it to LPG. It makes good financial sense to use LPG if the foreseeable price of fuel is above P50/L for the long term.

And given you can "afford" it, it doesn't mean you shouldn't save money on areas you can save money.

I have seen bigger and more expensive luxury cars converted to LPG. Why pay for expensive gasoline when you can use a fuel that costs a third or half of gasoline by simply installing a conversion kit?

[Horsepower]

If you'll ask taxi drivers driving LPG-fed units, they'll usually tell you that their throat always feels dry and most of them developed lung spots. Word has it that Govt officials are stopping the campaign to restrict auto-LPG systems. Even DOE Secretary Reyes scoffed at an impromptu interview over the radio by Ted Failon if I remember it right.

Anyway, since Taxis are maybe less maintained than say private units, it's best to weigh these things.

If you find the fuel expense of a big engine hideous, then it's best not to get one.

[Gerbo]

There are some who want to taste the lap of luxury without shelling more for it.

To be honest, i have yet to hear any validation of its long-term effects.
