Auto-LPG Conversion Thread

Just acquired an A33 Cefiro with 40L LPG tank. Did all the fluid changes but I noticed it consumes a lot of LPG. Approx 4km/l. What needs to be checked?

Maybe it's just the large engine (3.0L V6)? You can have the LPG system checked with it's installer. IF the air/fuel setting is on the rich side it could explain your car's gas guzzling ways.

BTW, what is your normal daily route from home to work, etc? How heavy is the traffic?

Sampaloc area to Roxas Blvd. Mostly moderate traffic. Just had the MAF, TB and plugs checked. They're all ok.

Try getting some highway driving as well to observe your FC. The case with my Altis, i average between 9.5 to 10.5km/L in city driving, the same as my gasoline figures however in highway driving, i'd get around 10.5 to 11.5km/L with LPG as against 13km/L to 16km/L with gasoline. When Xoom checked out my tuning, he saw that i was basically stoich in the low rpm range and running rich at the high rpm range so we would have to work on tuning that.

Thanks. BTW I insisted to spray some contact cleaner on the MAF and Carb Cleaner on the T/B. There was a slight improvement in engine response. Hopefully an improvement in FC. But I'll definitely need to have the LPG system tuned. Its an SGI kit BTW.

Update: Found out that the car has no thermostat installed. It takes a while for the engine to warm up. Will install a thermostat today...

Hi guys, i am currently deciding whether to convert my car to 100% lpg nextweek.
My ride is a 2004 4x2Honda CRV 2.0
Regarding the conversion, can you guys help me out choose between Manila Auto Gas and Petron Xtend?
I would gladly appreciate other opinions.
And can i refill on any lpg stations? I have read that refilling on "that" particular lpg station caused them a decrease in car performance.
My area is Las Pinas and budget for conversion is 40-70k.
Thanks!

That's good to hear. That should help improve your FC outright IMO. Do give an update if it helps.

I'd suggest you have your VQ engine compression tested. Since the thermostat was removed, chances are it may have overheated before and a badly overheated VQ plain sucks

Medyo maliit yung tank niya for a V6 engine. Most biggies use a 65 (or 70/80L?) tank.

I'd suggest a complete tune up of the kit first. The 2.0 V6 Cefiro does around 6km/L+ at the average in Metro Manila traffic before.
