I have used Mobil gas with 93octane and I experience lunging and stalls. When I have used Shell gas with 93octane it seems to run fine. Anyone else experience this??:shrug:

I use Mobil and if there isnt a Mobil station around when i need gas then I will hit Sunoco. I try to NEVER use Speedway gas. I only experience the lunging when Im going a steady 25 to 30 mph, when the tach is around 2200 to 2800 rpm's. But I havent gotten the YFRO update yet! I bet you pay a premium price for 91 out there in Cali dont you? I think I paid $1.59 for 93 octane the other day. :burnout: :rockon:
never noticed any difference, sheetz-mobil-exxon-shell, whatevers cheaper for premium i just let the computer figure it out. :shrug: Now my 11-1, .62 lift 327 roller motor 67 firebird was a little different;-)
Man , I'd love to be paying 2.09 a gal for 91. I use Sheetz, and the cheapest I have seen here in northwest pa is 2.55 a gallon. I was paying upwards of 3.60 a gallon this past fall. My region sucks. Costs over 25 bucks to fill up on empty
