I am running 93 and one bottle of Gunk Lead Subsitute per tank in my stock 230. The dash plate says Min Octane 85(where the h#!! do they sell 85?) but a friend of mine says that the old leaded gas was rated differently than the new stuff. He recommened the 93.

What do those of you with the 230 run?
Is the lead subsitute doing me any good?

Thanks,
Karl
