My 1996 Buick Roadmaster with 244,000 miles and always used Castrol GTX petroleum oil, but with synthetic oil prices coming down I'll strongly considering changing to synthetic....any ideas or reasons why this wouldn't be good for this old 350 V8 LT-1? Would welcome any thoughts or experiences on this before I make the change...
