Auto-LPG Conversion Thread

Maybe we could call ourselves "United LPG Owners, Limited"? ULOL?

Hahaha... Start the club... we'll join. ;)


I'm looking at some of the weird idle issues being an issue of low vacuum at idle, with the LPG vacuum tap being made on the vacuum line leading to the idle air control valve.

This would be why aircon use would affect LPG. I'm going to research and see if there's a better way to connect the LPG to the vacuum system.

Do you guys have lubrication for your valves? Di ba mauubos yan in the long run? Also, you know anyone with a turbo car using LPG?

[tebs]

that's the reason why you should be using your petrol fuel every now and then, to lubricate the valves.

may oxygen sensor na pala sila, di ko naabutan the last time i went there last month. sayang!

Still none. Still none observed. And, like I said before, this is an issue that most likely affects only cars from the mid-80s and older, cars which need leaded gasoline to lubricate the valve seals. Ghosthunter has been using LPG for nearly four years on his 96-98 Corolla with no issues.

Er... not that old... more like over 2 years and few months. And it's a 99 Corolla.

Hi Guys! XOOM Auto Gaz, Inc. would like to inform everyone that we already accept VISA and Master Card credit cards for our Conversion. So inviting all to visit XOOM for your conversion requirements. To our fellow LPG enthusiasts, we are working on applying the same facilities for filling up at our Autogas Petronas Timog Station to serve you better. Look out for this.

I'd also like to apologize for the inconvenience experienced because of the Quezon City side walk project program being done. Thank you for all who support our station.

Cheers!

Xoomaster,

same price ba ang conversion par cash and card?

Xoomaster,

Hi userfriendly. Cash prices are card prices would differ but not much. Feel free to drop by our shop so we could discuss your concerns and needs! Cheers!

Assuming your system is from Greenfuel, you can get more advanced diagnosics on your engine and LPG system. But since greenfuel has acquired a wideband oxygen sensor (similar to the one at speedlab), it's possible to get a good tune up at greenfuel.

But if you have some weird problem in which greenfuel cannot find the source of the problem, a visit to speedlab would be advised.

In the earlier months of greenfuel, visits to speedlab were suggested because of certain longer term effects of using SGI-LPG system were showing up. These days, most of the problems have been solved so there is less need for a visit to speedlab.

Thanks ghosthunter. Appreciate it. Yes I have an SGI system from Greenfuel.

Guys, I have a couple of questions about filling up. Is there really a hazard when filling up LPG with the engine running? I know even gasoline stations recommend to turn off the engine when filling up but they're not really strict on that and I've always filled up gasoline without turning the engine off.

Secondly, have you experienced immediately after you fill up LPG, when you start the engine, the engine dies? And when you start it again, you get unsteady idling for about 30 seconds before it stabilizes again?

No, I don't experience such.

You got SGI, so it will start with Gasoline. Probably you have stale gasoline in your tank or clog gasoline fuel lines.

sharing some info after my PMS:

- one of the plugs are abit oily
- air filters are oily
- failed emission test (a week ago)

Im worried bout the oily plugs and air filters. Is it because of oil contaminants from dirty LPGs? or engine problem? Ive done some research and oily air filters could be caused by PCV. anyone familiar with PCVs?

I brought my xtrail to Greenfuel for tune up. Need to observe and check again my air filters and plugs... sana wag engine/loose compression problem..

[niky]

PCV is possible... but it ccould be your LPG.

I have experienced oily LPG contamination, but it only affects the spark plugs having black deposits and it does not affect the air filter. If LPG oily contamination all plugs will be affected and not only one, since all LPG injectors draw fuel from a single LPG rail (Valtek from GreenFuel).

It might be PCV or one of your cylinder has blown/loose valve seal.

Question:
How much peso do I save for every liter of LPG?

From my estimates, every car has its own answer with said question. As for a 2004 Outlander. Here is my answer:

GIVEN:

Unleaded E10 Fuel Consumption: 7.10 KM/L
Unleaded E10 Peso per KM: 7.5 P/KM
Price of E10 Unleaded: 45.72 Peso/Liter (as of 26 October)

LPG Fuel Consumption: 5.55 KM/L
LPG Peso per Kilometer: 5.75 P/KM
Price of LPG: 30.20 Peso/Liter (as of 26 October)

SOLUTION:

Compute for the Total Price per liter of LPG
1. Get KM/L difference of E10 and LPG

7.10 - 5.55 = 1.55 KM/L = KM/L difference

2. Using Ratio and Proportion: Get the Price of the P/L difference:

KM/L KM/L 5.55 1.55
____ = ____ = ____ = ____ = 8.43 P/L = Difference P/L

P/L P/L 30.20 ?

3. Get total price of LPG = LPG P/L + Difference P/L

= 30.20 + 8.43 P/L = 38.63 P/L

4. ANSWER: Get the difference between E10 P/L and No.3

= 45.72 - 38.63 =7.09 Peso/L

[SIZE="5"]Currently, I save 7.09 pesos for every liter of gasoline.[/SIZE]

mas maganda kung per kilometer driven
P45.72/7.10km=6.44pesos/km pag gas
P30.20/5.55km=5.44pesos/km pag lpg

in essence for every kilometer driven, P1 ang nasave mo, so kung 50km ang travel mo per day P50-ang savings mo a day.

kung 10 km ka lang a day, P10 lang ang savings mo not worth it.

Question lang sa long time users ng LPG:

baket pag sa TOTAL ako mag load ng LPG umaabot ako ng 39-40 liters, pag sa Petron ako mag load 32liters lang tops.

edit:

parehong from empty, as in ayaw ng umandar ng kotse unless gasolina ang gagamitin

The cut-off pressure for that "TOTAL" station is higher than at Petron.

Sa akin baligtad.....

Pag sa Petron(Buendia) ako : 37 - 38 liters
pag sa Total(Kamagong) ako : 30 - 32 liters

Depende po ata sa calibration/pressure cut-off ng pump nila......
(pero yung consumption/mileage ko is pareho.....so lumalabas lugi ako pag dun sa Petron na yun ako nag pi-fill..)

[n5110]

kung 10 km ka lang a day, P10 lang ang savings mo not worth it.

not really worth it kung 10km (ave) ang tinatakbo mo everyday. more benefits pag ave mo is 50km and above. tsaka hinde nag roroll back ang lpg natin

my experience sa total alabang until 36 li, sa cleanfuel 29-30 lang for a 40li donut tank. hinde naman ako lugi kasi kino compute ko based sa cut off pressure per station. try niyo i monitor on a week basis per station para more or less you get the same amount of lpg, then compare the mileage.

Hi guys,

What's the best LPG conversion kit for my 1.6 Lancer with EFI? Where do you suggest I get it, and how much will it cost me?

Of course "best" doesnt necessarily mean "most expensive"

hi anybody,
i'm thinking about converting my ford escape 4x4 v6 engine to lpg and have been reading the previous posts regarding greenfuel and denso, open and closed loop...and have just gotten overwhelmed. Can anybody recommend the best lpg kit for a ford escape, where and at what price range? how long will it be until i see a return in the investment considering that fuel prices have gone down? help!
