How to read Vacuum Gauge

Post by MX3ak »

After some research along our forum and some other sitesin the web about how to read a vacuum gauge. I came with this one http://www.classictruckshop.com/clubs/e ... ac/uum.htm for example.
Now, what about our mazdas, what are your specs?

Mine does show a maximum of 25'' doing downwilll with engaged gear.
While the gauge marks go to 30'' maximum, should I be worried because of my lower readings?

Leave your opinions please ;)

30"s is a complete vacuum, no engine sucks that hard. 25"s is strong. Note higher altitudes lower vacuum readings.
