Went to Cat gas sa Visayas Ave. The one beside Caltex, kinausap ko at ang sabi nila na yung gamit nila ay galing NAIADSS din. Parang branch kung baga. Cat gas is also known as Autogas Manila.

Price of conversions is based on engine displacement and if EFI or carb. EFI is more expensive. I don't have a price list but I think the 25K is for a 1.6 carb engine.

My cousin had his honda civic converted. 3 years na, wala naman problema. Safe na safe. Sa renewal ng registration no need for smoke emissions testing. Tahimik pa. Same power observed with non-converted.

our group here in cebu have converted an F-150 V8 4WD pickup and a "96 Lexus LS400 4.0Liter V8, BOTH vehicles are MPFI's. mileage for both vehicles is almost similar to using gasoline, savings are on the costs difference between LPG (26\ltr) and gasoline (over 40/ltr). uphill power and acceleration is not an issue as long as correct tuning of the system has been done.

would it be worth it?

**ale828** · July 19th, 2006 06:38 PM

i think its the car and its engine na talaga ang problem. The Optra is a gas guzzler talaga, changing to LPG doesn't change the fact that the engine dynamics are not in sync with the car. The car being a gas guzzler from the start doesn't pertain that you will get better mileage if you switch to LPG because your using the same engine. It will only mean that you are spending less money on the gas as compared to before but that wont change the fact that the Optra is still a gas guzzler.

dear ed chua:

have u tried installing those free flow k & n air chargers they are less constricting and give you more power as your engine can suck in more air

Wondering lang, is it safe to assume na parehas lang ang ratio ng stoich ng LPG vs Gas? 14:1 din? If not, pano yung mga settings ng ECU? With a carbed car or a non-EFI car I don't see why LPG conversion can't be done, with later model cars, pano yun?

Given these conversion kits are available in other countries, I assumed they already have figured it out.

I'm sure they have, but how?

Parang tipid siguro (bottom line in peso) kung sinalpakan mo ng LPG system ang Pride, Charade etc...

Then again, how long (in savings) will it take before you recoup your 25-30K back from the conversion?

it really depends on how much you use your vehicle. In my car, I would probably get the ROI in 7 to 8 months. In a smaller engined car, it would take a fair bit longer, like 30% more time.

I wonder why there is not LPG conversion kit for diesel engines since I have seen referense to such in other countries...

bilis lang pala... Hmmm...

Let me read through the thread before I ask another question hehe... thanks GH.

Simple computation lang naman eh.

Assuming you get the same fuel milage with LPG as with gasoline. So the difference in fuel price will be you savings factor.

so if the difference in fuel price is P20/L ... and multiplying that to the number of Liters of fuel you use in a month. Assuming you are getting the standard EFI kit costing P28,000... divide that number with the savings per month. That would be your ROI time.

**theveed** · July 21st, 2006 03:35 PM

GH: Did the math, laking tipid nga hehe... Tipong pwede ka mag full tank less than 1K...

Technical question lang... Yung LPG route nya is from tank to the valve thing and then vaporizer and then fuel injector?

How will the injectors work if vapor nalang ang squinisquirt sa makina? Or binabypass na yung fuel rails?

2nd... Does the LPG tank utilizes the same fuel pump as the petrol tank o ibang linya sya talaga?

Salamat, just wanna know more about how it works and how the juices flow... Makes a lot of sense to get this than to buy a newer, small engined car.

Parang pwede ka nang bumili ng gwapong A31 Cefiro tapos LPG or any other older large cars hehe.
