I am on a road trip across the country and noticed that my oil pressure gauge is pegged at above 5, unless am at idle. Then it reads about 1 bar, which is correct. But the moment I rev engine it jumps to above 5. Along with that, I have noticed that at times it will bonce between 3-4 and 5 a few times, then peg back out above 5.
Checked oil level, its within specs.
Any ideas on where to start to diag this issue?
