Another question I have that was mentioned earlier was the pressure relief valve. I took it apart and appears to be nothing but a spring in there. What function does that do. Not sure if I understand how it can control oil pressure??? Ken Clark

I use either Valvoline or Castrol petroleum based oil. 10-30 in the winter 20-50 in the summer. I change oil every 3,00 miles or so and I have a couple of small leaks, about a quart in 3,000 miles, so until I rebuild my engine, it doesn't seem worth the cost to go to synthetic.

I'm using a 10w40 mobil1 which I have not had any problem with any of my other cars.
