    Chrome Digital Oil Pressure Gauge is rated 2.3 out of 5 by 3.
    Rated 3 out of 5 by from Pressure Gauge is aggravating. The gauge must have been made some where else other than in the USA. I can set the gauge to PSI and the next time I look it has changed back to BAR. The default setting should be PSI not BAR ! !

    Rated 3 out of 5 by from Great gauge if you like to read oil pressure in bar This is a beautiful gauge but my complaint is that you cannot lock it in one display mode. Every time I get on the bike I can pretty much be assured that the units will change from psi to bar or bar back to psi. No way to lock it out as far as I can see. Once they come up with a way to lock it I would then recommend it and give it 5 stars.

    Rated 1 out of 5 by from Does not last, will break. I have had 3 of these and they have all stopped working, the one on my bike is blank as we speak. Not designed very well...

    Asked by: cableguy2117

    any reason you couldn't mount this up near the speedo?

    less shaking may make the gauge last longer
    Asked by: mike01fxd
    Hello Mike01fxd The use of Parts and accessories not designed and tested for your motorcycle may have negative consequences on the performance of your motorcycle and may create conditions not covered by the limited factory warranty. There are a couple of reasons why a part may not be recommended fitment: 1) Testing could not be completed prior to printing of the catalog – Always check for the latest fitment information. 2) Specific fitment not recommended on all models because a configuration did not meet our Harley-Davidson performance criteria.

    Why would I need to know my oil pressure and/or how does a gauge like this benefit me?

    Asked by: EddieG
    Hello EddieG, The reason it is beneficial to know your oil pressure is to make sure your engine and oil pump are functioning properly. If you loose oil pressure and continue to ride your bike, you will do major damage to your engine. Thank you for your question!
