Re: [St] Using Regular Gas In A Sprint ST

maybe so, but our Sprints are spec'd at 87 (or is it 89? -- no matter) so
using anything HIGHER will not improve your gas mileage as a great many
users 'think'

my point about mileage assumes that all else remains the same, which
apparently is not the case for all motors
