I myself could notice a difference between cheap 91 octane and the normal 92/93 octane Amoco I run.


...all I wish was 94 octane was available at the pump here... I sure could use it!!!



I usually run 93 octane in my '98 EO. When I use 92, there's a slight loss of grunt, most noticiably at the lower-end.

Sunoco has 94 octane here. But I haven't been curious enough to pay an extra .12 - .15 per gallon to experiment.
