ok, so the major brand companies for certain will have the same additive packages in the low grade as in thier higher grade fuels (such as Shell/Texaco and Chevron)? Thanks for the clarification. So, should I look for 86 (opposed to 87) octane if I can find it since it is the lowest reccommended level from Honda? Although it is only 1 point, it is only 2 extra for mid-grade. I guess I could call up because I don't think I have EVER saw a pump with less than 87 in my life.
