Using Oil Pressure to Gauge Oil Change Intervals
#21
i've used mobil1, shell ultra, royal purple, valvoline synpower, plain castrol gtx... over the 9yrs i've had the car with a oil pressure gauge.. there is no diff in oil pressure between the oils, nor is there a diff in oil pressure from the time i put the oil in to the drainage time ~5000km later.. and this is checking oil pressure cruising on the highway at 100kph with oil temp at ~85C
so imo using oil pressure to check when to change oil is a FAIL

what's the resolution on your gauge, and what make is it? 5000 km (about 3100 miles) is not a very long OCI, so I wouldn't expect to see a significant change in viscosity that quick
