1. Valvoline regular oil
2. 10w30
3. Approx 2500 miles since I re-built it completely.
4. Temps when I am driving the car range from 50 to 90 degrees. I live in Michigan, so only driven from late spring to early fall. Otherwise, it gets really cold when in storage.

Castrol GTX 10-30 with a K&N oil filter (very important).
About 3000+ on rebuild and I drive only when weather is
cool (max in the 80s). Oil pressure range after warm-up
is 25 at idle upto 60+ cruising with a high volumn oil pump.
I take oil seriously.
