I’m using royal purple on this tank, 93 octane, and I can feel the difference, running map 2. I feel a stronger pull using Royal Purple than running 2 gallons of e85 on a full tank of 93 octane. I also ordered Torco and Race Gas concentrate, I’m going to run one bottle each on 93 and see how they compare with feel. I’d like run on a dyno to compare as a controlled expirement, but so far Royal Purple has a noticeable difference on map 2.
