Hey everyone, so I replaced my oil with 5 quarts of Valvoline High Mileage 10w-30 and a Mobil 1 Extended Performance oil filter. The oil pressure gauge is immediately behaving normally again and wonder if there was actually less oil in the engine than my dip stick was showing. I dont have enough experience to be able to eyeball the amount of oil coming out of the pan to know. I did keep the filter, which was a Fram PH5, which I wont be using again hearing about how you guys talk about Fram, and plan to cut it open to see what if any debris is caught in there.

Hopefully that lifter noise will go away now that there is plenty of oil back in the system, time will tell once I take her on the freeway again.

Thanks for all the tips.
