My oil pressure read around 15 - 20 PSI on the gauge at idle, until know. I had the lines replaced, they where made by a hydraulics shop, the oil cooler was also replaced at the time. I also had oil changed and put on a K&N oil filter(just figured it'd be a good time to have it done). Now my oil pressure is just pegged above 110 PSI, I am just trying to make sure its the gauge and not something majorly wrong with my car. Thanks for the help.

 

Um, well that's crazy.

The oil cooler lines, what would be the ID (inner diameter) rating? I guess if they're a hydrolic shop they would have made them the same eh?

Just out of curiosity, why didn't you by mazda oil lines?

Sometimes the oil pressure sending unit goes wack, but in my case its always reads zero instead of 110.

Tap the sending unit arround a little. That's what I do to mine when every once in a while it reads zero

 

I talked to the owner of rotary resurrection and he said that he sees alot of people doing this, my guess would be that its just a more durable line. I think it might be the sending unit also but ill have to check it out this weekend. Thanks for the help
