ARTICLE: 6 Driving Tactics to Save Gas This Summer

[CVT]

Tactic No. 4: Cruise at a Slower Speed

Since the power required to overcome aerodynamic drag is a function of the velocity cubed (in other words, it shoots up quickly), a car's jump from 40 to 60 mph requires less fuel than the increase from 60 to 80 mph. (The hit to fuel efficiency is roughly twice as severe in the higher range.) So go slower, right? Well, yeah, but fuel efficiency isn't the only thing that matters. Some studies suggest that the old 55-mph limit saved fuel but cost us more in terms of lost work hours. Then there's safety: Going 55 mph when traffic is cruising at 70 can be dangerous to everyone. Just don't go 80. That will drain your tank quickly—and the costs add up if you also have to pay for a speeding ticket.


Tactic No. 5: Climb Slowly (When It's Safe)

Imagine driving on a flat highway and approaching an overpass. From a fuel-efficiency standpoint, the best strategy is to turn off cruise control and forget about maintaining a constant speed up and down both sides of the grade. The theory predicts that, and our data prove it. The physics work like this: Lifting off the accelerator while traveling up the hill and allowing your speed to decay trades some kinetic energy (related to speed) for potential energy (related to the car's tendency to roll downhill). You regain the kinetic energy—and get better gas mileage—on the backside. While hyper-milers—who are obsessed with getting the best possible gas mileage—claim significant economy benefits from this technique, our results showed only modest gains. Two things did happen, though: (1) We drew the wrath of a lot of drivers following us, as evidenced by their single-​finger salutes; (2) We were nearly sideswiped by an impatient 18-wheeler. Yes, the method does work. But we'll save it for lightly traveled roads.

Great tips! Ok ang "Right turn only" Thanks for posting this!

Guys is it true that coasting downhill in neutral will damage your automatic tranny?

delikado yan. you're just relying with your brakes

Why would you want to coast downhill, especially if it is a long drive downhill? You are more sure to encounter overheated brakes and the resulting loss of braking power.

Just put your shifter to L or 2 when going downhill with an AT car to control your speed.

I love going down hill in gear; on the fuel eco meter i get the best FC (99.9km/L) when the car is going downhill in gear and you don't have to press the gas.

From experience sa Dalton Pass (Nueva ecija to Nueva viscaya), engine brake rav4 gen 2 4x4 A/T

pag asa D going downhill 60kph
pag asa 2 going downhill 40kph

Meron pa ba gas ngayon na walang E10?
Petron blaze 100 yung Euro 4 ethanol free. Meron pa ba iba?
