ok i got this dohc with bout 260k miles on it and am swappin it out with my sohc that burns oil like no other, well anyway i had a t3/t4 turbo on dohc boostin bout 15 psi up and down the street, prolly bout 100 miles on it, never had chance to get tuning and car was trashed, so i sold kit to a buddy and bought this 89 coupe, well it burns oil like theres no tommorrow, gotta put about 2 quarts in after a 70 mile round trip to school and back, which sux, sooo anyway i got this dohc motor, it has new oil pan gasket and valve cover gasket, h20 pump etc. had no probs when was runnin turbo, but i was wondering if i should go synthetic, or stay with 10/30 regular oil in the dohc with tons of miles. any pros cons to this idea, cause its all i got right now, till of course i can save for my long awaited rb25det. lol (will prolly never happen) well thanx hope to hear from some peeps soon

I switched to mobil 1 10w-30 synthetic in my sohc that had 270k miles when I turbo'd it, no problems so far.
