Not really "best". Like I said earlier in this thread, the fuel economy gauge is just a visual tool to help you adjust your driving habits. It will not automatically result in better FC. If you think your driving habits could be improved to maximize FC, then have one installed. You can make it like a game to try to keep your Vacuum gauge to read closer to "green" as much as possible.

extra unleaded para mak tipid sa gas kung de gasolina oto at dipende din kung ganu na katanda ang isang sasakyan, pero kung mga 2013-2014 model na sasakyan yan sigurado matipid pa mga yaan.

yes, if you have leaks in the installation, your engine can run a little "funky" because the air-fuel ratio will be leaner than it should be.

Seyoso hindi ito pwede sa diesel engines?

Pero nakita ko sa ibang UV express (Crosswind, Advies, Urvan, et al.) meron sila nito? So, saan kaya nila kinabit yung mga vacuum gauge nila?

By the way, para sa mga non-OBD or non-scannable cars you could also use your vacuum gauge to diagnose engine problems.

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
