A question........I took my 92 coupe to a lube shop yesterday for the first oil change since I bought her 2 months ago. The vette has 40,780 miles on her and because I have been at sea most of the time hadn't got around to doing this until now. Anyway when they pull the drain plug the oil coming out was black and looked very old. I don't know what synthetic looks like having never had it before but didn't think it looked right :confused . Well the service people recomended a engine flush. I wasn't sure about the ramifications of this so I just had them change the filter and fill it back up. Is there any problems with flushing a LT-1? I figured I would ask and see before risking damage to my engine.......thanks for the help!
