    Great product just 1 issueEverything is great for most part, accuracy, simplicity, great contrast. Only issue I’ve noticed if you get wet weather condition, it builds up condensation from inside and is no longer readable.

    Does what I need it to do, looks great.Fast responding (it is mechanical anyway), accurate, looks great. Classic AutoMeter. Wish they would come with the copper line versus the plastic, but I can see why it doesn’t to keep pricing cheap otherwise people would complain I’m sure. The copper line kit was cheap, like $10-15 or something like that so definitely go with that over the plastic. LED upgrade is available from AutoMeter as well, but found them to be pretty expensive. Got some T3 194 LEDs from for half the price.

    Real oil pressure instead of idiot lightI finally got around to putting in an actual pressure gauge on my track car. I favor the mechanical type and these have worked for me on other cars. Works as promised and easy to install.

    Yep it’s a gaugeThe reason for the 5-star review is due to the fact that it is a great gauge. I won’t fault Amazon for an improper picture.The item recieved doesn’t look like the picture. I know, I know, in the description it states 0-100psi not the 0-150 shown, but I was hoping that the gauge would have been the new style of ultra-lite with the white face gauge. Instead it is the old version with the silver faceplate.Good gauge, easy to install.
