The marketing of fuels as "regular" and "premium" was absolutely genius, as they have the majority of the public totally fooled into thinking higher octane fuel is somehow better for their car. It isn't. Use the lowest octane fuel that your car requires. Period. No boosters, no additives, no nothing. Unless you enjoy spending money for the sake of spending money, in which case why not donate it to charity instead? Then it might actually do some good.
I have heard this several times before and I am in agreement, but a lot of people seem to agree that the "lead substitute" is necessary if you are running an old engine that hasn't been upgraded with the hardened valve seats. What are your thoughts on this?
