Mechanical Oil Pressure Gauge
Part No. 6144
Retail Price (Wal-Mart)
We threw this wildcard in the mix just for fun. Even though
the Equus 6144
is a 2" gauge, not a 2-5/8" gauge, it does come
with its own face plate
and Wal-Mart retails it for a shocking $7.28. Being the last
gauge in our comparison and given the fact that almost every
other gauge was spot on at 40
psi, we were dying to see if this thing would measure pressure
accurately... considering the price. According to the Equus
website, the Equus brand targets the "value-conscious
do-it-yourselfer". A bad sign. Here's what we found.
The hardware kit and instructions were complete with the
added feature of an extremely cheap face plate that matched
the $7.28 retail price.
Like the Summit gauge, this Equus gauge listed the grommet
as optional. Since Wal-Mart is not a performance store
we let the grommet omission slide.
It's true, you get what you pay for. Of the six mechanical
gauges in this evaluation, the Equus was the only anomaly.
It read 10 psi above all the others at idle. 50 psi.
In our opinion the clear winner in this simple
evaluation of mechanical oil pressure gauges was the Auto Meter
3421 with the Stewart Warner 114521 coming in a close second.
Auto Meter's attention to the entire installation rather than
just the gauge itself supports their position in the industry.
This is most clearly demonstrated by their integrated and
ergonomic hardware kit. We do commend Stewart Warner for applying
the same rigorous standards to their enthusiast gauges as
they do to their OE gauges. Stewart Warner's "face-forward"
design is also an important requirement in racing applications.
Either way, both of these products are made here in the United
States and that is what should be taken away from this evaluation.
Spend the extra money, it's your project car for Pete's sake.
