I've rebuilt a 1952 Chevy 216. Two questions: (1) Would it be good to use synthetic oil (Mobil - which I understand is a synthetic/regular oil mix)? If yes, how many miles should I wait in using the synthetic oil, to let everything seat-in (with regular oil)? (2)If "no" to the above, is it now okay for me to use regular detergent oil, vrs. non-detergent? Thanks. Bob
