Fuel consumption affected by gasoline's Octane number?

[cast_no_shadow]

About sa tires alin ba dapat ang masmataas? Front or rear tires?

Mine's front is 2psi higher stated sa door jamb.

On a front wheel drive car, you will typically find higher pressures recommended for the front, because the engine is there.

-

For fuel eocnomy, you can increase tire pressures, but mindful of the limits of the tires. There are those who swear by pressures as extreme as 60 psi, but on rough roads, the energy lost to bouncing outweighs the drop in rolling resistance.

Typically, for daily use, you can go up to 35 or 40. The percentage increase in efficiency from 40 upwards gets smaller and smaller, so it's often not worth going over 45.

The only way to (relatively) accurately test the effects is to do a controlled test. Easiest in your case, since you're from the south, is fill the tires to the higher pressure, top up at Shell Mamplasan (first click) - drive to Southwoods, exit, turn south - drive to Cabuyao, exit, turn north - and repeat twice. Then refill, lower tire pressures (with a hand gauge, don't start the car yet!), repeat route (twice again) then refill (same pump!)

For effects of fuel... difficult to check. Only way to make sure is via multiple tanks, and as jut says, your average is still affected by the differing conditions... as well as the fact that your engine is still breaking in. (not break in as we traditionally think of it... more like "loosening up" from ultra-tight factory tolerances)

Most cars will keep gaining economy for the first 40,000 to 60,000 kilometers. Hell, our CR-V's economy peaked at around 100,000+++ kilometers!

So ibaba ko po sya sa 32 psi? Kasi un ung nasa manual at sa driver side door

Alin ung break in period

Not to be rude, but I think it is better for you to read the Owners' Manual first before asking people who might not own a car similar to yours.

usually mas mataas sa front ng around 2-3psi kumpara sa rear. akin 32 front 29 rear ang nasa manual pero usually ginagawa ko 36 front 34 rear since luma na sasakyan ko at medyo malakas na sa gas para mas matipid konti at hindi naman gaanong matagtag tolerable lang.

with regards to octane rating, if i'm using 95ron 10km/l lang maabot ko pinakamataas na 12km/l kung highway. pero kung blaze 100 or phoenix 98 gamit ko mix driving is 12km/l normal at 15km/l kung hiway lang talaga.i dunno pero ganun talaga experience ko kung hi octane. siguro kung old na ang car mas better kung hi octane ang gamit?i'm not expert on this pero yun experience ko.

you dont need to be an expert, all you need is to be observant

phoenix petroleum came out with a commercial about its premium gasoline fuel (98 octane). notice the car utilized is an old mustang car and driven in an urban setting at night with not much cars riding along. the commercial claim a restoration in power which leads to a question among consumers, is it true or not?

its TRUE, because an open road will result in a pronounced effect for such a product just like in your highway driving experience. but its a waste of money in a heavy traffic

With our Navara and X-trail I find that with the way I drive, premium fuel gives better mileage. That may mean nothing because every trip to the pump is different. Road and traffic conditions change so much it's impossible to compare. That's not even counting other factors like weather, elevation, your mood, etc. Only way to really tell is through a controlled test where there are no variables.

For gasoline I fill up with Petron 93 Ron or Shell 95 Ron. For diesel I fill up with Petron Turbodiesel. There's a big difference in how much more fun the cars are to drive vs a small increase in price. I stopped measuring fuel economy a long time ago. Useless with today's traffic.

Oo nga naman.if long drives, i would still prefer hi-octane since iba talaga ang hatak.pero kung traffic, good luck. but here in Davao, traffic isn't much of a problem naman kaya I still prefer using hi-octane since nakakasave naman ako ng about .60 to .70 cents per kilometer. So i wouldn't mind using it everyday since halos same lang naman ang gas expenses ko.

With regards to the tire pressure, follow the car brand's recommended but don't exceed the tire brand's recommended pressure. The higher the pressure, the harsher the ride. Check the pressure in the morning when tires are cool & weekly fill up. As tire temp increases, so does the pressure. Nitrogen is more stable than air. Play around with the pressure till you find one that suits you.

Pa OT lang mga sir.
Ano best way para ma compute ang fuel comsumption ng car?
.
Ang alam ko kasi full tank ko. Then set to zero ang ODO. Then after ilang ride. Full tank again then check kung ilang litro na karga devide sa ODO.
.
Any way? O ito lang talaga,,

Yup that's the best way to compute. Do it over several full tanks to get a consistent reading.

There are apps for Android and iOS that help you with that. I use Road Trip for iOS and aCar for Android.

Ok sir thanks.

MIT researchers take on high octane fuel

[Tj_abs]

Sir, medyo ot lang, na try niyo na phoenix 95-97 octane? Ok ba siya?

Been using the 98 octane of phoenix for 1yr. Have no complaints.

Vpower nitro from shell. Maganda takbo ng 04 jimny. Better on my 16 swift

Q: i let my dad to drive Cx-5 with skyactive i-stop function and Lancer Gt-a. .4B11 engine., and both car resulted on avg FC of 11.1L/100km, does this means that he drives that efficiently no matter what car he droves??
