DIY: Fuel Economy Gauge for your car (to lower your car's fuel consumption)

[vegetablejoe]

Hi.

Are most vacuum gauge brands available today reliable? I've only had experience with VDO which I bought 30 years ago.

If some are better than others, kindly let me know which are best. Would like to put one in a '98 Sentra 1.4 A/T that seems to guzzle gas more than it should.

Thanks!

Kindly note that a vacuum gauge (used as an economy gauge) will only help you to adjust your driving habits. if your car has problems/defects which would cause it to guzzle fuel, this mod will not fix that problem.

I used Auto-Gauge in my own mod. It's affordable and comes in styles/sizes to match my requirements.

Yup. Thanks. Just want to "calibrate" my light foot on that Sentra, and want to eliminate poor driving habits from the equation, before looking for mechanical problems. I got 9 km per liter when I drove that car a few weeks ago. The car isn't mine, but am told is malakas sa gas by the previous driver (mukhang lagi nakabukas makina and aircon while waiting).

I'd also like to put a gauge on a CRV, and on a Jimny I just acquired, but am afraid of voiding the warranty on the latter.

Will look around for that brand. Salamat!

The 1.4L a/t Sentra is a bit of a guzzler really due to it's small engine on a big body. We had one before and it consumed around 7km/L+ at the average if memory serves me correctly. Highway driving could get even worse as we had to push the pedal hard when the car is loaded up.

Do you want to improve your car's fuel economy and you think you have tried all you can with your car?

Have you tried installing a fuel economy gauge on your car?

A simple vacuum gauge will do.



You just have to remember which values are for poor, fair, and good fuel economy.



0-5 - poor
6-10 - fair
11 - 17 - good
18 - 23 - idle

----------------------------------------

Why a vacuum gauge? Because it gives the driver a visual reference how his "foot" will result in what kind of fuel consumption. This is only a reference to the driver.

If the driver ignores the gauge, then the gauge is pointless.

BTW, this assumes your engine is in 100% working order and have no vacuum/pressure leaks from the valves, manifold, hoses, etc.

good boy lol
