    Have 100 miles on my new Cat challenger. Have a couple of old muscle cars and use 100 octane low lead with them. Anyone know about the +/- of bumping up the octane on the girls?

    Well don't use leaded gas. That is no lead in your gas.
    BUT I personally used 93 and 91 octane this week, it makes a difference.

    For daily driving a good 92-93 gas is all it needs

    BTW, the 102 driving around is a waste and may even slow you down

    I love the smell of burnt AV gas.

    Motor last longer and smells good

    Lead really hurts nothing... except the oxygen sensors. They get poisoned by the lead and will stop reading correctly. So using leaded fuel isn't a real great idea.

    I remove them so it's irrelevant to me. If you do leave them in place the catalyst will just be rendered useless.

    I don't run leaded fuel. Really simple solution lol.
