Re: Oil pressure gauge

Good posts so far. The rule of thumb is 10 psi for every 1000 rpm. So 7 psi at idle is okay, but minimal. I think going with heavier oil is a good idea. I like 10W40 for engines with low pressure.

Also, in my experience, bleeding the air out of the nylon tube won't work. Most oil in the tube will drain out when the engine is switched off. Also, the air in the tube will not affect accuracy, but make the gauge react slightly slower... but likely not enough to be noticable.
