At the suggestion of this forum, I swtched filter brands to Napa silver. And new OCI to Pennzoil High Mileage after dumping the previous from 1000 mi.
Now the pressure gauge reads slightly higher. OCI was 4 quarts of 5w30 and 1 of 10w30.
Is the higher pressure due to the oil mix or filter?
Motor is 4.7 Dodge Ram.
