I think I'm going to install an oil pressure gauge.
I've been reading about mechanical vs electrical.
I Can't even find an electrical one, but anyway,
What are the real everyday chances of the nylon line bursting and oil coming in the car?
Thanks

Wise idea. Oil can be a crucial thing to monitor. I usually install one on a used car.
The one in my Mark is digital but I've used the tube ones before. Not really any chance that oil will leak out as long as you follow the instructions.
