    ... errr... use your car less?
    seriously, you might want to start playing with the jets. experiment with smaller jet size. but i don't know where you can get 'em anymore.

    You can cut your fuel costs by 1/3 to almost 1/2 by converting to Auto-LPG. The savings vary depending the the price difference between gasoline & lpg during the year.

    A carb type conversion to auto-lpg should be between 14K to 18K. Depending on your amount of use, the conversion can pay for itself (in cost savings) between a year to two years.

    whoa... mura na lang ha... i think it used to be 25-30K for carb cars di ba sir GH?

    i wonder how much for EFI V6 cefiros?

    to the threadstarter:

    dude ganyan yata talaga nissan sentra na carburator pa ang fuel system. nagkameron din kami nyan, ex saloon nga lang, parang LEC din with power steering nga lang.

    i had one of the carb expert guys in kamuning replace the carburettor jets with smaller ones and then tune the engine to run lean, that is, more air but less fuel.

    tumipid nga, pero ang panget ng takbo. parang taxi na karag-karag. if you can live with this, then eto pagawa mo.

    else, you can just ensure na malinis lagi ang air filter mo (carb cars are sensitive like that), laging tune up, palit ng mas malabnaw na langis (10w-30 will do) at magmaneho ng mahinahon.

    lower engine oil weight might cause the engine to run hotter specially in older engines. if this happens, you can try cooler plugs but with the ethanol/gasoline blend, the engine will probably be sluggish. try lowering the a/c thermostat to half the range.

    I've always thought that LEC-PS Sentras were DOHC 16 valve EFI's. Or is it only pertaining to the earlier models? I have a relative who owns one, and its true that it consumes quite a lot for a 1.3 liter. As for fuel saving, I'd say shift earlier (perhaps you can invest in an aftermarket tach), take it easy with the right foot, get the right tire pressure for your car and clean/replace the filters. That should help you save some. BTW, what kind of FC do you get?

    Tune the carb and clean it regularly. The issue with the carbureted 1.3 is that they're sensitive to running condition. I had to clean mine every oil change.

    Ang pagbalik ng comeback...

    Fuel saving tips.

    1. Keep your engine tuned-up always.
    2. Clean your air cleaner.
    3. Make sure your tire pressures are adequate.
    4. Be easy on the accelerator pedal. If you can maintain your speed below 100 kph.
    5. Plan your trip and choose the shortest route to your destination.
    6. Avoid abrupt lane changes on the highway.
    7. If possible turn your A/C off.
    8. Gas up with the cheaper Petron Pinoy Gasoline (88 octane). I recall your generation 2 Sentra can use a minimum 87 octane of gasoline.
    9. Minimize the weight of your car.
    10. Use public transportation or be with a carpool.
