Sure, I may feel better seeing a difference in oil pressure reading, but what does it actually accomplish in my daily driver, if said pressure reading is within operating spec?
Well lesee, being that most cars on the road today don't have oil pressure gauge and the ones that do are either useless or ignored by the general driving public, no a gauge really isn't of much use(how many cars do you see setting along side the road because they didn't have a oil pressure gauge?)...
For the ones that want to push the limits of how thin of a oil can I safely get away with, yes they are a good instrument to have... Me, I tend to error on the side of caution so will bump my oils up a grade and not worry, neither of my daily drivers have a real oil pressure gauge and I don't care... My Marauder and '69 Fairlane do have gauges that verify my method is working, haven't lost a engine due to a oil related failure in the 45 years I've been owning vehicles...
