Maybe I'm not as smart as i think I am. Started the vette a while ago. Man It made a lifter racket, like I've never heard it do. Only ran it 10 min on idle so I doubt the oil even got to room temp. Just long enough for the t-stat to crack open. It's about 34 deg today.
Valvoline 0W-20 I got on AZ sale last fall.
It's been fine with Pennzoil 5W-30 dyno and syn from Jiffy Lube Bulk. 15W-40 syn from Valvoline oil change with German Castrol make-up oil.
May have to rethink the thin oil bias.
