Drop In Oil Pressure

Engines wear, 97k on a Vette engine is no longer a new engine. I am sure that you have 'dropped the hammer' more than a few times, that is what a Vette is for, to have fun. You could try a heavier oil and I really prefer a pure synthetic. If you are really concerned, have a shop do a mechanical oil pressure test to verify that the 20-30 psi ( which is still very good at idle) is legit. Go from a 10-30 to say a 10-40 Mobil One, if it is good enough for a $450k Ferrari, well you know, it may just be good enough for a Vette.
