The oil filter in my truck was a Fram C-4.. and nasty.
Took the filter out all toghether, cleaned the housing, put 5 quarts in.. checked it.. put 6 in.. checked it.. ended up taking 7 quarts of oil.
I suspect that extra 7th quart was because the filter was gone.. which means if I put a filter in now, i'll have to drain a quart or so out.
Oil pressure gauge shoots up and stays solid at 15 during start and idle.. when you give it gas, the gauge rises up close to 30.
That sound normal/right?
