How to handle Hills Up & Down
Yesterday I went from Las Vegas (2500ft) to Mt. Charleston (8000ft) My MPG started at 59MPG and by the time I got to the top had dropped to about 43.5 I said to myself no worried I will make it up and some more on the way down. And I was dead wrong…
I descended mostly in "D" then some downgrades I had to put it in "S" and the briefly in "L". I noticed that as the car was coasting downhill my MPG numbers never recovered. At times my RPM’s in "D" were at 2500 and when I would depress the gas pedel it would actually drop to 2000.
In the end My MPG was 48. What was I doing wrong. The scanguage showed 0 ign and MPG at 9999 for over 10 miles.
Any ideas???
