I have a 88 Iroc with a 305 TPI. The car has 149,000 miles on it. Would i
benifit from switching to a synthetic oil? If so what kind. I live in
seattle so it doesn't get very cold. One issue that i have is that my valve
seals leak moderatly. Would using a synthetic make it worse?

Far too late in the life of your vehicle to move to a synthetic, IMHO. You
can try to wean your car from petroleum/paraffin based oils using Mobil's
new petrol/synth mix, but frankly if you change your oil when needed you'll
be just fine. When your powerplant craps out in another 50-75K mi. then
might be a good time to change to synthetic.
