I recently changed engine oil to synthetic and picked up 1.5 mpg city and 3 hwy. This data is by computer but something changed as a result of oil. Will hand calc it next fill up. Was getting ready to switch over to synthetic trans fluid for towing and wondering if that will contribute to better mpg. Always had 14-15 in city and no better than 17 hwy with 285 tires. Getting ready for gauges this month and maybe tunes later on.
