Vacuum Gauge / Happy with your brand & model?
 

Anyone have any good or bad experiences with your brand / model vacuum gauge?

What's the difference/advantage with the different types of vacuum gauge faceplates? Some needles rest in the middle. Some needles rest to the far left.

Searched, but can't find. Do they made a BlueTooth vacuum gauge so an app can give better analytics?

I've been using vacuum gauges since the 1950s to give me an idea of how hard the engine is working under various circumstances. I've never had one fail me, nor has any been more accurate than the others that I could tell. However, I like the ones with a 270 degree dial as they are easier to read precise values. They seem to be commonly available at local auto supply stores for $25 or so, a true bargain for the info they provide not just in regards to fuel economy, but for engine condition too.

Good advice on the dial face. Thanks for the response, Airstreamer67! :)

If your vehicle has a turbocharger you will need a gauge which will read both vacuum and pressure.

An OBDII reader like the Scanguage will also have manifold(vacuum) displays. They'll cost more than the basic vacuum gauge, but are easier to install and provide a lot more info on other parameters. There are OBDII plugs, including bluetooth, and apps for smart phones that do all the same as the readers.

Just research the reader and app to make sure it can get the data from your car. Some cars don't report everything to the OBDII.

Thanks, TrollBait, but my 1989 Civic is pre-OBDII. It was the first generation of Hondas to have fuel injection. That's the ONLY modern improvement. No airbags. Crank windows. No electric locks. But recently got 55mpg with it! :)
