Default Re: Miles Per Gallon

Another factor that influences economy which is not mentioned so far is gearing. My '28 Tudor has a 3.54 diff and Mitchell 26% O/D and B engine. The end result is not good. It is comfortable at 60 mph but even if I see an incline on the horizon, it slows down. Because the motor is lugging in O/D, it guzzles fuel. I have had it as low as 13 mpg - that is not much more than 10 miles per US gallon. I'm on the lookout for a standard gear set (3.78:1)
