6 Gas Mileage Myths

6 Gas Mileage Myths

It takes more fuel to start a vehicle than it does to let it idle.
People are really confused about this one, and will leave a car idling for half an hour rather than turn it off and restart. Some kids I know started an anti-idling campaign in the suburbs and are shaming parents into shutting down their cars. Idling uses a quarter to a half gallon of fuel in an hour (costing you one to two cents a minute). Unless you're stalled in traffic, turn off the car when stopped for more a few minutes.

Vehicles need to be warmed up before they're driven.
Pshaw. That is a long-outdated notion. Today's cars are fine being driven off seconds after they're started.

As a vehicle ages, its fuel economy decreases significantly.
Not true. As long as it's maintained, a 10- or 15-year-old car should have like-new mileage. The key thing is maintenance–an out-of-tune car will definitely start to decline mileage-wise.

Replacing your air filter helps your car run efficiently.
Another outdated claim, dating back to the pre-1976 carburetor days. Fuel-injection engines don't get economy benefits from a clean air filter.

Aftermarket additives and devices can dramatically improve your fuel economy.
As readers of my story on The Blade recall, there's not much evidence that these "miracle products" do much more than drain your wallet. Both the Federal Trade Commission and Consumer Reports have weighed in on this. There are no top-secret 100-mpg bolt-ons out there.

Using premium fuel improves fuel economy.
You might as well write a check to BP if you believe this. Only use premium if your car specifies it.

Add ko lang po ang personal experience ko para makatipid sa gas ay iwas traffic.

1. Agahan ang gising para before 7:00am on the way na me sa opis.

2. Late umuwi para iwasan ang volume ng mga tao na sumasakay ng PUV na gusto din makauwi.

3. Work from home kung wala naman meeting.

[yebo]

add lang ako ng isa.

kung sa south nakatira dun sa south magtrabaho, kung sa north nakatira sa north magtrabaho. hindi yung sa valenzuela nakatira tapos work sa taguig, o kaya sa bicutan nakatira tapos work sa QC. lumipat ka ng bahay, di naman magagalit yung multo sa bahay mo kung iiwanan mo e. makakabawas ka pa sa traffic.

Yebo, sama mo na rin yun GF. Kung taga-North ka, dapat GF mo taga dun din. Hahaha.

di ako naniniwala na myth to.

di ako naniniwala na myth to.

by your own personal experience ba sir?

[robot.sonic]

^ parang based sa logic na alam ko. pag restricted ang airflow sa makina parang hirap sya tumakbo. tsaka pinapalitan/nililinis ang mga air filter pag tune up e. kaya palagay ko may effect yan.

disclosure: di ako expert sa oto ha.

bka yung aftermarket air filter vs stock air filters ang tinutukoy nung author..

pagkaintindi ko ung mga old school engine ang tinutukoy ng author pero ung mga direct fuel injector na engine natin ngayon, kahit clean o madumi ang air filter same pa rin FC.

Still disagree. Nung marumi na stock air filter ko pinalitan ko ng drop in K&N, balik sa normal ang FC.

If you google some more, mas marami ang magsasabi na ang dirty air filter is one of the causes of high FC and that you must check it regularly.

By that logic, wag na tayo magpalit ng air filter. :D Pareho lang pala FE, malinis man o marumi.

Seriously though, modern engines with ECM/PCM can adjust fuel delivery based on the amount of air. However, it can only do corrections up to a certain extent. If the air filter is dirty enough, you'll find yourself flooring the gas pedal more, which translates to frequent additional squirts of fuel from the injectors.

Yes sir, I have read some articles and nababanggit nga ung air filter for improving the FC. But wala akong nabasa regarding oil and fuel filter? wala ba ito bearing sa FC improvement?

Naniniwala ako dito. May carburator kasi yun engine ko. Manual adjustment kasi ang Air Fuel Mixture.

[yebo]

blocked air filter = more intake power during the intake stroke = less efficiency.

[Chikselog]

Parang malayo na ata ang relation ng oil at fuel filter sa FC.

[oj88]

Oil weight can also influence FE. honda recently started transitioning from 5W40 to 0W20 in their worldwide direction to improve FE on their car models going as far back as 2001.

Not a believer in this because this is exactly what I've been doing the past 6 years. I live in Parañaque and work in Mandaluyong and Libis, but my fuel economy still hovers around the 11-13 km/L range and I don't drive like a saint either.

One thing that works in my favor is timing. In the mornings I drive against the normal flow of people who are mostly headed to Makati from the north of the metro. Shooting for an early entrance at work usually means very little traffic. At night the reverse isn't as effective or as applicable but it's not an uncommon sight to see a relatively free flow of traffic either.

My drive to work is 20 km one-way. That's another factor that plays to a fuel economy advantage. On longer drives, traffic willing, the engine spends more time running in its normal temperature range - it's not wasting as much time trying to warm up only to be shut down after a relatively short drive. You can't say the same for a commute to work within the vicinity of the same municipality.

Just offering my input.

Yes, i have read a thread regarding honda's 0W20. It might give better FC but downside for me, it might hamper your engine protection.

It's somewhat of a misconception that a higher weight oil would necessarily offer better protection. It has more to do with engine tolerances. Simply put, modern engines that are certified for 0W20 have very tight tolerances and using thicker oils can prove to be detrimental. It takes more energy to push heavier oils into passageways, orifices and between moving components. If the oil is too thick, it may not be able to protect parts that are practically molecules apart. Thicker oils can also bring up the oil pressure that can weaken or break seals.

Just a word of caution.

yeah but did you get the point? it was not about FC. it was about living near where you work. save time, save gas, better life too. read it again please.
