[SIZE=5][SIZE=3]Experienced low fuel consumption, rough idling, lack of power at low rpm?
One Saturday morning, I opened the hood to look for the source of the lpg smell that settled in my garage. I leaked test all of the joints but found none. And so I repeated it, but with the engine running. Wala pa rin ako leak na nakita. But what I noticed was a very noticeable "hissing" sound coming from where the lpg mixer and intake manifold meet (I use an EROOM kit on my Ford 1.6 Lynx). I have suspected this before as early as when I was watching the kit being installed. This was a very likely source of air leaks because metal meets metal without an effective sealant or gasket. What they usually use for this purpose is the silicone sealant usually used for glass, tiles, and roof leaks. I doubt whether this is impervious to lpg.
And so I disassembled the joint, scraped the silicon sealant, cleaned both ends, AND
applied THREE BOND sealant/ gasket maker on both ends. Malabnaw ang Three Bond so you have to apply it sparingly, then wait around an hour for it to become putty-like before assembling the components. I made sure the joint is tight and centered, and that the locking bolts are equally tightened.
END RESULT: idling is smoother (of course the tach needle still wanders a bit, but not like before), there's low-end power (I can run at 2000rpm or below in 2nd gear w/o the engine stuttering), my FC is now at 9 kms/ltr city, up to 15 kms/ltr highway (took a trip to Lipa via Star Toll driving leisurely at 90-100kph).
THREE BOND sealant is tested to resist LPG. I bought it at just P65 from my suki auto supply (smallest tube).

The tank meter and the dashboard light will always be different. The tank contains about 20-40% air. It always does. This air reflects in the tank reading but not in the dashboard light. So even when we fill out tank to capacity (till there is No Flow sa pump), the tank reading will only read 60-80% full, but the dashboard light will already indicate full.
Kailan ba magroroll back ang price ng LPG?
Ilang beses na nagrollback ang Gas and its now 46 pesos/Liter nalang.
LPG sa Total Alabang 31.68 pa rin ganun na siya for more than a month or two.
I had my Mazda 3 converted at GreenFuel last August 2008.
Eversince then I had no problems with Normal Driving laging Idling problem lang.
I brought it back to them 2 times na kasi the engine dies when idling.
Usually in traffic. Siguro in a day mga average ko 3 times namamatayan.
GreenFuel naman is accomodating to fix the problem. I'll bring it back again probably tomorrow.
My observation. After driving about 20 to 30mins when the engine has reached its normal temp. Ayan na most likely when I stop there's a chance it'll die. It doesn't die immediately as in RANDOM siya.
My car on LPG always experience the coughing syndrom when idle. Na lessen yung coughing everytime i bring it back pero it still dies which is very irritating.
My FC...hmmm well city driving is at 8.5km/L in LPG its about 7.5 to 7.8km/L.
La lang just sharing.
Kailan ba baba ang LPG? hehehe (That's my rant for the day)
naging problema ko rin ito for 2 weeks after i had my car converted to LPG, binalik ko sa greenfuel for check up and adjustments. itinaas lang ng konting konti yung idling ko, after this wala na akong naging problema. no more rough idling during stops.
about the lpg rollback, ito din ang tanong ko..bakit ni piso hinde bumababa.. hay
btw, my car is using emulator kit.
Got the same recurring problem before and became a constant GreenFuel customer for LPG calibrationYou are right that GreenFuel is very accommodating, Mike at one time even suggested to fix my ride in my Makati workplace.

I thought it was spark plug related, so I have tried of all sort and brands and now I have handful of thembut I was wrong.
The culprit was LPG oil contamination, so I change filling station and chooses the very new Total LPG station in N. Fairview and all my previous problems are now eradicated. Engine runs smooth and no hesitation even on uphills.
Ok guys. Forgive me. Please bear with me. This is the third time I'm trying to post the same image.
Apparently, Tsikot Gallery was under maintenance the past couple of days so that could be the reason why I'm having difficulty posting this very simple picture.
Hope it works this time. Otherwise, I could really be doing something stupid...

nag cut pa pala ng metal part for the lpg filler. yung sa akin sa ilalim ng bumper less worries for water going into the trunk ang problema lang hirap ng konti ang mga attendant dahil kailangan lumuhod to connect the pump nozzle. thanks for sharing sir.
its been a while since i posted. some updates/questions:
1. failed emission test but i was running on gas while ngpaemission ako. anyone experience the same?
2. hows the tune up interval for LPG SUVs?
3. i used to have the same problem with paolorenzo, (taas baba ang idling, ng-stall, etc.) after Green fuel tuned it, ok na. although my mga occasional instances na namamatayan/ng-jejerk/low RPM ako specially when i turn -off/on my aircon. anyone experience the same?
4. I only fill up sa petron, no oil contaminants ba ang petron?
thanks sa LPG, i was able to buy a scooter.. hehe.. sana bumaba naman ang LPG like gas.![]()
no fail on emissions, catalytic converter still functioning.
Typically just keep your old tune up schedule. If you have it done every 5,000km, keep it the same when using LPG.2. hows the tune up interval for LPG SUVs?
My brothers had the same problem with their LPG-SGI cars. Return to greenfuel for tune up and problem solved. Either sparkplugs or oil contamination is usually the culprit.3. i used to have the same problem with paolorenzo, (taas baba ang idling, ng-stall, etc.) after Green fuel tuned it, ok na. although my mga occasional instances na namamatayan/ng-jejerk/low RPM ako specially when i turn -off/on my aircon. anyone experience the same?
Depends, the Petrol Wack Wack, Shaw station is known for "dirty" LPG. Avoid like plague.4. I only fill up sa petron, no oil contaminants ba ang petron?
I'm pretty much happy with my LPG tuning at this point. No significant power loss, idling quite stable although occasionally in traffic it fluctuates for a couple of seconds but quickly recovers (although namatayan na rin ako ng makina once in bumper-to-bumper traffic). I'm getting 5.9km per liter on LPG. I used to get around 6.5km per liter on gasoline.
That being said, if I bring my car to Speedlab, will I be happier?Will I accomplish anything significant? Also, will I need to bring my car back to Speedlab after my regular tune-up?
Salamat po!
We have been exchanging info on performance, maintenance, conversion quality, and fuel consumption for quite some time now. Maybe the time is ripe to put our vehicles to the test.
LPG Econo Run Anyone?
or what about an
LPG Time-Speed Rallye? :uptight:
i had problems with petron araneta ave's lpg. lots of oil contamination. i'm filling up at manila auto gas on the opposite side of sanctuarium.
previously, i had rough idling. it would go up and down erratically. but now, after having it tuned up at green fuel, changed my filling station, it idles more smoothly. although i don't get any more discounts (3% from petron), at least the car runs smoothly now![]()
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.
CannonBall Run nalang, from manila speedlab office to Subic Freeport...
discarte na ng driver kung saan ang best route.![]()
Mayroon na ba AutoLPG Club?
