Hello, I just recently acquired my dad's 1995 Dyna Super Glide. It has 13,000 miles on it and hasn't been ridden since 2010. He never rode it much and changed the motor, transmission, and chain case fluid only once back in like 2005. So now that its out of storage id like to change it before I ride. But, back in 2005 he bought a big case of HD brand synthetic oil, that he says can be used in motor, tranny, and chain case and theres still half a case of unopened bottles in the garage. Since this synthetic oil is 8 years old but still technically "new" and "unused" will it be just find to use it in my oil change? Or do I buy new? Thanks.
