Posted January 12, 20196 yr comment_565799 With today's gasoline, should I revise the timing curve for my S130 1981 280ZX? If so, can someone provide appropriate information? My plan is to use 91 Octane fuel without additives. I can get it here locally. Engine is designed forĀ "Unleaded Fuel Only" as labeled outside of the fuel filler.
