Hi again, In a conversation with a truck mechanic, octane came up. My 2002 F53 chassis with a V10 has only been run on 87 octane. He went into a discussion about lower octane firing more suddenly that higher octane fires more slowly but longer in duration but burns more completely. I'm wondering if the electronics of the 2002 V10 engine would adjust to a higher octane resulting in a little better mpg. It wouldn't take very much of mpg improvement to off set the extra 20 cents out of 260 cents. Has anyone, tried or tested the value of using higher octane on this engine? Tim fm CT
