Oil pressure?
I just installed a Voltmeter and a Electric Oil Pressure Meter, I was wondering what I should be seeing as far as oil pressure Hi & Low pressure? I own a 2003 Civic DX Coupe 5spd.

Re: Oil pressure?
Cold at start I see 50 psi, 12 normal, have seen as low as 6 (with needle going up and down) as 5-6 with the oil temp at 230, but that was after 15 minutes in open track day.
It's useful if you do high revs all the time and suddenly the pressure drops. Then it's time to brake and turn it off before it causes more damage.
If you never goes past 5k there's not much advantage.
An oil temp gauge is more useful a s long as you understand how engines and heat transfer happens over time, otherwise you just putting pretty watches

Re: Oil pressure?
Just out of curiosity, where/how did you install the pressure sensor for the e-gauge?
I ask b/c I tried this on another car, using an adapter at the oil filter, and the electronic gauge measured completely differently than a mechanics gauge connected to a service plug at the oil pump. Not only did the old-style mechanical gauge not measure the same as my readout, but the difference between the two was not even predictable, or proportional to the rpm.

Re: Oil pressure?
Remove stock oil pressure switch, screw in adapter "T" fitting, reinstall original switch and connect wiring for the warning light as stock, then connect whatever you have for the gauge.
I've never heard of a filter adapter.....but then I'm old school a lot of the time.

Re: Oil pressure?

They are sold on ebay, just have to look up something like Honda Filter adapter in automotive, or Honda sensor adapter, oil cooler adapter, etc.
I think I got mine from Summit Racing.
On my other car, the area behind the engine where the low pressure sensor screws in was not easily accessible, but there was a plug near the oil pump where a mechanic would connect a conventional oil pressure gauge... no such thing on this engine, I assume?
