Any idea how can I possibly lower the fuel consumption of my '90 corolla gl? On the average nasa 6km/li lang eh. Kahit bagong tuneup, bagong oil filter, bagong air cleaner. Tried experimenting on using diff brands of gas pero walang significant effect. I also try as much as possible not to be heavy on the gas pedal. My friend recommended installing gas saver but I'm afraid na baka humina ang hatak. May pag-asa pa kaya to? Or talagang that's already the best I could get with an old car?
here are some things that i discovered about this car.
1. just like most cars, it hates short trip, less than 5 kilometers. travelling at least 6kms per trip will yield better fc.
2. it hates traffic too.
3. i've had some success combining shell's unleaded and premium, you might want to try. usually loading up blaze, yields good fuel consumption too.
4. keep your fuel and air filter clean. replace you air filter every 2,500 kms and not every 5,000kms.
5. you can have your air/fuel mix adjusted, baka you are running rich. adjust it clockwise until the engine vibrates, yung parang mamatay, then adjust it back counting 3 turns. if in doubt, ipasalang mo sa emission test center, turn the air/fuel mix screw until mag okay sa reading.
5. keep your carb clean, spray with carb cleaner regularly like when you change air filter.
6. from time to time, go for a long drive up north, hanggang pampanga at least, para ma decarbonize, pag puro city driving, carbon tends to accumulate inside the engine.
7. kung wala pang leaks, try using a 10w40 viscosity oil.
i would advise against changing to smaller jets as it will affect performance, you will have idling problems and acceleration will be significantly weaker.
