Fuel saving tips [merged threads]

[BeetOls]

oo nga grabe talaga...kahit anong pagtitipid mo (driving style, etc.), ramdam paren talaga ang fuel price hike...whew!

advantage lang nito pag tumaas taas pa is that we might be seeing lesser cars on the road...less traffic = better mileage; pero nakakatakot na siguro pag ganon because it might mean that the economy is on a flap.

If only they look into developing local raw materials for fuel...like Biodiesel, laki siguro ng ibababa ng price ng crudo...

light foot the best.

although i am extremely amused with the boost gauge sa pajero, i can't resist in making it move around a lot. :lol:

Ang nagmamadali, madali rin mauubusan.
Iwasan ang biglaang arangkada, ratrat, at hataw. ‘Pag mabigat ang paa sa gas, madali maubos ang gas.

Ang tumakbo ng matulin, mabilis din maubusan.
Karamihan ng mga sasakyan, matipid ang konsumo kapag tumatakbo ng mga 80 km/hr kaya subukang ito ang itakbo kung maaari.

Dapat mahangin ka.
‘Pag kulang sa hangin ang mga gulong, mas maraming puwersa at mas maraming gas ang kailangan para paikutin ang mga ‘to.

Ang gaan-gaan ng feeling.
‘Pag mas mabigat ang sakay, mas malakas ang konsumo sa gasolina.

Pag naghihintay, patay.
‘Pag matagal-tagal kayong maghihintay, patayin ang makina para tipid sa gasolina.

Ang magaling mag-alaga, magaling magtipid.
Mahalaga ang regular maintenance ng sasakyan. Palitan ang spark plugs once a year o bawat 20,000 kms. Palitan ang brake fluid every 2 years. Palitan ang coolant every 12 months. Sa mga sasakyang may automatic tranmission, mag-fine tune regularly. ‘Pag alaga ang makina, sulit ang bawat patak ng gasolina.

Ang magaling magplano, malayo ang mararating
Planuhin ang paggamit ng sasakyan para makaiwas sa traffic at mga ‘di kinakailangang lakad.

Nasa timing ‘yan.
‘Pag nagmamaneho ng manual na sasakyan, kumambiyo sa tamang rpm (2800 rpm to 3200 rpm).

^^^Totoo ba to? kasi may nabasa ako dito sa forum to shift * 2000rpm to save more fuel..?

Most of the tips are correct naman, except for the last one.

I shift at 2000-2200 rpm if I want to save fuel. 3200 rpm? Parang medyo hataw-hataw na yan ah.

[niky]

Depends on the engine, probably. Some engines will bog down if you shift too low, and if you're on the highway, shifting at very low rpms means you will be lugging the engine hard to get to your cruising speed.

Personally, I shift at 2200 1st to 2nd (very short first gear), then 1800-2000 from there on up when I'm in tipid mode (lots of torque). Other times, I shift at 2500.

[squala]

It depends on the car. Shifting at 2K in a Corolla GLi and in an SiR are not the same. The latter needs to be revved harder since it's torqueless. The former doesn't have as much RPMs so it can carry more speed at less revs.

You should shift in such a way that your engine won't struggle, or if you can afford to still step lightly on the pedal. If you shift too early and step heavily on the next gear, you won't save fuel.

kung city driving, mabilis pa nga 80kph eh. Mostly 60kph lang ko, nakakainip pero ganun talaga eh, tiyagaan lang.

They should have added the value of using the 'a/c less often than the usual'. Eto crucial part din sa fuel savings (less power demand, more torque pati, hehe), makakatulong talaga. But depends on every driver kung kayang tiisin ang polluted environment naten.

However, I've been doing this for years narin (at night, madalas NO a/c na talaga <= nakagawian ko na!), obviously, kita ko yung benefits as well. :D

For shifting, mostly 2k rpm!

Top 10 Fuel Saving Tips

From Aaron Gold,
Your Guide to Cars.

Whether you drive a two-seat hybrid or a three-ton SUV, chances are you can squeeze a bit more distance out of each gallon of fuel. These ten fuel saving tips have served me well over the years, and they can help you improve your car's fuel economy and take some of the sting out of high fuel prices. Most of these tips will give you a very slight increase in miles per gallon (MPG) -- but use several together and the gas mileage improvements will really add up.

1) Check your air filter
A clean air filter is the key to good fuel economy. A dirty air filter restricts the flow of air into the engine, which harms performance and economy. Air filters are easy to check and change; remove the filter and hold it up to the sun. If you can't see light coming through it, you need a new one. Consider a K&N or similar "permanent" filter which is cleaned rather than changed; they are much less restrictive than throw-away paper filters, plus they're better for the environment.

2) Check your tire pressure
Next to the air filter, under-inflated tires are one of the most commonly ignored causes of crummy MPG. Buy a reliable tire gauge, check your tires when they are cold (driving the car warms up the tires and the air inside them, increasing the pressure), and keep them properly inflated. Use the inflation pressures shown in the owner's manual or on the data plate in the driver's door jamb.

3) Slow down
As speed increases, fuel economy decreases exponentially. If you one of the "ten-over on the freeway" set, try driving the speed limit for a few days. You'll save a lot of fuel and your journey won't take much longer. Just be sure you keep to the right, so you won't impede the less-enlightened.

4) Hang with the trucks
Ever notice how, in bad traffic jams, cars seem to constantly speed up and slow down, while trucks tend to roll along at the same leisurely pace? A constant speed keeps shifting to a minimum -- important to those who have to wrangle with those ten-speed truck transmissions -- but it also aids economy, as it takes much more fuel to get a vehicle moving than it does to keep it moving. Rolling with the big rigs saves fuel (and aggravation).

5) Accelerate with care
Jack-rabbit starts are an obvious fuel-waster - but that doesn't mean you should crawl away from every light. If you drive an automatic, accelerate moderately so the transmission can shift up into the higher gears. Stick-shifters should shift early to keep the revs down, but don't lug the engine -- downshift if you need to accelerate. Keep an eye well down the road for potential slowdowns. If you accelerate to speed then have to brake right away, that's wasted fuel.

6) Get back to nature
Consider shutting off the air conditioner, opening the windows and enjoying the breeze. It may be a tad warmer, but at lower speeds you'll save fuel. That said, at higher speeds the A/C may be more efficient than the wind resistance from open windows and sunroof. If I'm going someplace where arriving sweaty and smelly could be a problem, I bring an extra shirt and leave early so I'll have time for a quick change.

7) Back off the bling
New wheels and tires may look cool, and they can certainly improve handling. But if they are wider than the stock tires, chances are they'll create more rolling resistance and decrease fuel economy. If you upgrade your wheels and tires, keep the old ones. I have fancy sport rims and aggressive tires on my own car, but I keep the stock wheels with a good narrower-tread performance tire in the garage. For long road trips, the stock wheels give a smoother ride and better economy.

8) Clean out your car
The more weight your car has to haul, the more gas it needs to do the work. If you're the type who takes a leisurely attitude towards car cleanliness -- and I definitely fall into that group -- periodically go through your car and see what can be tossed out or brought into the house. It doesn't take much to acquire an extra 40 or 50 lbs. of stuff.

9) Out with the new, in with the old
Many people keep their old cars around even after they buy a new one. A spare car, especially if it's an econobox, can be good insurance against temporary spikes in gas prices due to world events. The costs of keeping the car may or may not be less then the fuel saved, but it does allow for more predictability in your budget. My old beater doesn't look like much, but it goes 10 miles further on a gallon of gas than our regular car. For that, I can afford to look bad!

10) Don't drive
Not a popular thing to say on a car site, I know, but the fact is that if you can avoid driving, you'll save gas. Take the train, carpool, and consolidate your shopping trips. Walking or biking is good for your wallet and your health. And before you get in your car, always ask yourself: "Is this trip really necessary?"
