So you had somewhat lower mpg at 70-75mph. But you also had significantly lower in-town mpg during the same time. So it's hard to say what caused what. > Be interested in how your second test run goes - I would do it > sooner than later as the octane ratings will change in the coming > weeks as spring gets here and that will throw off your > calculation substantially I think. Actually I don't recall ever seeing the octane levels change around here. But our winters (in Colorado but not in the mountains) are a lot milder than yours. In any case, I'll do both the high- & low-speed tests at about the same time, probably on the same tank like I did last week, so the gas formulation shouldn't be an issue. Gary
