Unleaded fuel in 80 EuroS - should I add something?
My Euro 80S does not have a catalyzer (and sounds great). But, since leaded fuel is no longer available in Europe, what should I do? Add something, leave alone?
I have an old Triumph convertible, and the advice there is not to bother with any additives. Apparently, those engines build up a protective coat on the valves, which means you can go unleaded for a long, long time, once they have have drunk enough lead earlier. What is the advice for an early 928 in Europe? SimonC |

Hi,
Definitely 98 unleaded, and no need for lead substitutes. My owner’s manual only makes a reference to don’t use fuel with LESS than 98 octane. Regards :thumbup: |
All Porsche's since about 1977 have hardened valve seats - can use unleaded with no modifications or issues on all 928's.

Thats great. The previous owner had been using some swedish additive, which I didn't like the look of, so its nice to be able to drop that.
Thanks for the answers. |
