Don’t coast downhill in neutral. When you’re in gear and foot off the gas you’re in defco (deceleration fuel cutoff) using zero fuel.yesterday I mis-judged how many miles it was to Culpepper by way of an end-run around a nasty accident on US-29 so I looked at my GPS and it said 16 miles to town, and my dash read 12 miles to empty. I short-shifted and used all down-hills to coast in Neutral. I was on hinky backroads with no centerline and little traffic. Was hoping one of the county 'thru-roads' merited a run-down garage with a gas pump of any kind. No such luck and I'm having to up and down some hills. Got to the first gas station on the outskirts of town 1 mile after it hit 'zero'. There was probably a few more miles left in there but I didn't feel like pushing the car or having to get a can and walking back.
Was glad to pay $4/gal for 93 octane from the Marathon gas company.
