My sister is giving me her husbands 1995 Corvette that was in storage for 10 years. He passed away last year from cancer and she wants to keep the car in the family and driven. I have changed the coolant, rear diff fluid, auto trans fluid, belts, hoses, and new tires. The V8 has 60,000 original miles and it was well maintained until put away for a long time. My question is should I do any kind of engine flush? I plan to use a quality synthetic either Mobil 1, PP, Royal Purple? Should I just do a few short oil changs? Also what weight oil should I run? I can't seem to locate the owners manual. Thanks!
