Yes the gauges are buffered, but the pressure is reading what the pressure is after the buffereing period, which is only a few seconds. Have you ever conntected an oil pressure gauge to an engine? It will bounce around a bit. I'd rather have the guages buffered.

WTF is the point of buffering?

I put a VDO mechanical oil pressure gauge on my Rabbit GTI (it didn't have a sensor, you had to hook up an oil hose to the back of it), and that thing was awesome how it responded. At startup it would stay pretty high for awhile, since cold oil is thicker......But after a few minutes it would start dropping down as the oil heated up. Eventually it would drop down to say 20-30 psi at idle, but then rise to 60-70 psi when you blip the throttle. I don't remember the exact pressure but that's not the point. Why would you want it buffered? A true enthusiast wants to know exactly what's happening when it happens.

its to keep mechanically illiterate fucktards from bringing the car back for unnecessary diagnostic service because "the gauges were moving". shit you not.

certain cars dont have them, the nsx's oil gauge is sensitive enough you can see a drop when the vtec system switches cam profiles. scc also made a big stink about the srt4 having "real gauges"

sad but probably true

100% true. i work for whats basically a car rental service and you'd be floored at the kind of stuff these morons report. my favorite is the seatbelt alarm, which they always SWEAR they wore.

While there is some truth to this, the main reason is for the aesthetic look of the guage needle. Who wants to look at guages that sit there and bounce around every half second? It gets annoying after a while.

The NSX guages are still buffered, just not as long as say a Buick.

.

Why would it bounce around every second? Mine didn't. It only moved when I revved the engine.

Simple...your gauge is not that accurate. It is prolly in the zone of +/-3 PSI in order for the spring to even move. It is just a mechanical buffer instead of an electronic one.

If you were measuring the oil pressure in 1kPa increments, the thing would be bouncing all around at steady RPM because the oil pump creates pressure oscillations. You just choose to buffer it to 300kPa instead of 1kPa. Get it? It is really no different that waiting a few seconds and averaging the results, but rather a different way of doing it.

Oil pressure in my park ave was actually pretty damned responsive. Could always tell at a look when it had burned through another quart

The buffered gauges are the same, but the accumulation is over a few seconds so the gauge doesn't sit there and bounce around.

You are not calibrating or diagnosing anything. You don't need instantaneous pressure readings other than to make yourself look cool. To me it is just shit moving around that I don't need to see. Let me know when the oil pressure drops below a level that will do damage to lower end bearings. That is really all I need to know.
