Auto-LPG Conversion Thread

[dencio1976]

it's true with the toyota engines regarding sludge problems. ive used low oil grades before and even now. im thinking i got away with it since i had drivers using premium gasoline before. the post regarding lubrication in premium gasoline may have been the key why i didnt get sludge problems with premium as compared with unleaded n lpg. ill be experimenting with the best suited oil. be trying toyota motor oils. i hear even some eg hatchback racers use this oil. any confirmation on this?

i cant have semi synthetics or full synthetic oils as options for now. i change oil every 2weeks to a month depending on the color of oil.

air filter change can be as fast as less than a month for our taxis. less air to pull in thru the intake meant more lpg to be pulled thru. therefore af is rich. but then engine would run cooler? wont it?

if it's color orange with the sparkplug that's the average color of what you'll find on taxi's because it seems to be the one with the best km/liter consumption. with a private car, this would be ok to lean. preferred with red colored sparkplugs to run cooler. this may definitely be one reason why engine temps run higher. but then again if u turn it to red, consumption aint as efficient as compared with the orange colored sparkplug.

what color of sparkplugs do you have normally on your lpg cars?

im seeing 2 potential problems now, low grade oil and lean mix(orange). with the 1st potential prob, that's easy. few additional pesos and wham, better engine oil. but with the lean mix of colored orange sparkplugs, could prove to be more difficult with drivers wanting more kms/liter. i think id prefer the "more maintainance" than lose the drivers. unless i can source out a red colored sparkplug with the same fuel efficiency.
