Fuel Consumption : How to improve or retain efficiency

[Gian Paulo]

Gud AM tsikoteers. Aside from changing filters, what other means to bring back or improved FC? Thanks.

Keep the engine in tip-top shape. Change oil (in the proper viscosity) and perform all required PMS as prescribed by your car manufacturer. Engines will eventually lose efficiency as they age. However, keeping it healthy will prolong its life and keep it within its optimal operational efficiency longer.

Equally important is your driving style. Hard accelerations and decelerations will not only use up more fuel, it will also promote additional mechanical wear on the engine and powertrain, losing its efficiency somewhat. Even a hybrid that's driven hard will consume a lot of fuel.

Why are you experimenting with monograde oil?

perhaps if you investigated on how you lost it in the first place?

Still planning in my next OCI with Pertua Oil and Metal Treatment?

I keep my revs low (usually at around 1750-2000rpm, not exceeding 2500rpm), avoid abrupt throttle input, avoid excessive idling, change fluids and filters on time, keep the radiator clean, inflate tires to proper tire pressure... Did i miss anything? 😁

Set the a/c to 28-30c. Cover all windows

Use Uber na lng. Kidding

Remove all unnecessary loads and change to low rolling resistance tires

Monograde is a no-no from a fuel economy standpoint.

Here's a tip: Buy any recent issue of Top Gear Philippines... or the current one, preferably, and get a discount voucher for Shell Helix Ultra 0-40w.

Saves you about 250 pesos on the price of the oil. In other words, libreng magazine plus 75 peso discount.

-

But more seriously, you want a multi-grade with the lowest cold number possible for economy reasons... then stick with 30-40 for the second number in deference to our weather.

-

Also, buy a good spark plug wrench and periodically check your plugs. Learning how to read your plugs can tell you a lot about your engine.

guys, question. is 5 to 6 km/l reasonable for 100% pure city daily drive on a 9 year old Altis 1.6 A/T? moderate to heavy traffic mornings, light to moderate traffic afternoons (makati > ortigas, vice versa)

[GTi]

Bro, I expect that kind of gas mileage from our 2005 Accord 2.4 A/T. I'd be complaining of bad gas mileage already if I had a 1.6 doing 7km/L.

Quite high. Lowest I've gotten was 6 km/L and that was on a really really slow crawl, average speed of 3 kph.

On regular heavy traffic (10-12 kph), I get around 7-8 km/L.

damn.. ganon ba? Where's all that fuel going LOL. kaka change oil ko lang e 10w-40 Helix Hx7. Lifetime airfilter, Simota. Nag palinis na rin ng MAF.

Where should I start? spark plugs?

[minicarph]

Magpa-wheel alignment ka then change your tires to brandnew

Did you change the oil and fuel filters? When was your last ATF change? That may be a factor. As mentioned, wheel misalignment can also cause a spike in FC too, as does low tire pressure.

Given the car is in good condition, driving style will really make a good difference. Assess your driving habits from time to time (you can check for references here and on other sites on the internet).

Traffic is also quite bad already. Our M/T Altis hits around 8++ to 9 km/L in the city (morning and evening CBD traffic). If your car does nothing but city driving, maybe you also have carbon build-up as well (that can affect FC in the long run). Taking it out on a long drive after a tune-up or doing some hard, high rpm runs will help.... or you can spend for decarbonization.

Thanks for your replies, all of you.
only changed my engine oil and engine oil filter, not the fuel filter and ATF. from the looks of it eto ang assignments ko:

1. Wheel alignment and tire pressure.
2. Driving habits
3. ATF/Fuel filter?

During provincial/out of town holidays I have no problem reaching 13-14 km/l. Hope I can improve my City FC. Will update after checking.

It could also be your route. Ortigas to Makati, right? I get 6.5 km/L with my Altis (1.6 also but MT) on that route.

Of course, maintenance is a big factor as well. When I got my Mazda 3 (older than your Altis), it had a dismal 4.5 km/L. After changing its oil, ATF, spark plugs, fuel filter and air filter, I'm now up to an average of 5.5 km/L. Still bad, but considerably better than before.

yup, this is what I keep telling myself rin sir. When I switched jobs (used to live/work in Makati) dun lang nagbago. I was checking my fuelio logs and I was consistently hitting 7, 8 or even 9 km/l back then. Now swerte nako sa 6 km/l. Wala pakong 1 year sa new route ko. Baka rin mas aggressive ako mag drive pag traffic. Anyways, before anything sundin ko muna ung steps and report back.
