Timing Curve for L28 with today's gasoline

Featured Replies

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 for "Unleaded Fuel Only" as labeled outside of the fuel filler.

You should be fine with stock timing
