fuel

I have a 2007 Miata MX-5. The owner's manual says to use 95 octane fuel. My previous 1999 MX-5 had no such requirement. Does this engine really need the higher grade gas? Has anyone used 87 octane routinely and found a difference? Thanks. Jim

Hello all, I am needing to find a fuel tank for an 02/03 Protege 5. Rust has apparently eaten through part of it. However, apparently they are on backorder until October. I'm a little hesitant to believe that, so if anyone knows of another part source, I'd appreciate it. :-)
