Rec'd Octane for 911SC?
What type of gas (87, 89, 93, 94+ octane) runs best in '79 911SC? Mainly interested in street use with light track use.
Any suggestions?

If I put less than 91 of the pig swill AZ calls gasoline, my '81 pings like mad.

Mine is happy as a clam on 87 here in the Pacific Northwest. I don't think I've ever heard it ping.
As far as I can tell, the only thing higher octane will get you on these relatively low compression engines is a bigger fuel bill

But the minute the car gets further South (as in OR and CA), the quality of fuel seems to diminish. Then, have to fill with 91+. Still good fuel available in the Rainforest.
