Just not sure if the vacuum and other stuff are operating at normal level

bighatch65 Rookie Author Newfoundland Posts:29 Points:177,265 Joined:Aug 2012	Message Posted: May 23, 2013 12:19:34 PM Ignore bighatch65 Report Abuse In neutral the engine is always burning fuel. Some newer cars shut off the fuel if left in gear and coasting (down hill) i.e. no throttle so you get distance with zero fuel burn. My manual trans Dodge Challenger shuts off fuel when coasting in gear. If I go to neutral or press in on clutch fuel is being burned...

dontuknowOH Champion Author Ohio Posts:2,100 Points:36,605 Joined:Aug 2009	Message Posted: May 15, 2013 8:38:53 PM Ignore dontuknowOH Report Abuse Today I went 40+ miles into the country and nailed several downgrades in N.. cog, on the way back, took another route going then had only gradual up grades therefor I was able to stay in O-Drive and keep rpms lower. Strong winds hurt mileage today, better coming back home.

mybigtruck Sophomore Author San Jose Posts:141 Points:201,600 Joined:Oct 2009	Message Posted: May 11, 2013 10:54:01 AM Ignore mybigtruck Report Abuse Coasting down a hill in neutral costs fuel to keep the engine spinning at least at idle speeds. In a diesel, leaving it in gear especially when the torque converter is locked consumes zero fuel. So, no, I never coast in neutral

Only if the hill is steep enough as the generator acts as a brake.

It works for some and not for others. Surprising how under informed some are, with comments like giving up control of your car. Slopes can be gentle, moderate or steep, on a gentle slope most cars would probably lose speed in neutral, just like with engine braking, no big deal. On a moderate slope the car might maintain speed, perfect solution, rather than lose speed under engine braking. Steep slopes, be careful. Enjoy what you drive.

How about this - - How many people shut off their engine when sitting at a RR crossing with a train going by or just waining for sonething or another ?? I have heard that that saves a lot, a surprising lot !!

More efficient (and way less dangerous) than letting my engine idle on the way down.
