CODFISH driving
 

I did a search on CODFISH and only got the glossry.
1.Do I have to go in neutral before shutting off my engine and coasting?
2.Also sometimes when I am off I'm thinking if my cluster guage is reading speed = 0 mph, then I have to turn the key to accessory so the miles rack up. Otherwise I would not be adding mile to odometer while I'm coasting until engine is turned back on, right?
3.My 2006 Dodge GrandCaravan SXT will not start up from neutral. So It means I have to pull over and stop, put car in Park, then start engine. Does this sound right?

Miles on the Nissan look good from doing this CODFISH technique a little: 320 miles 3/4 of a fuel tank used.

I have never heard it called Codfish Driving, EOC, would be the term we kick around here alot.
If and when you do EOC, turning the key back to its on position is best because your digital meter will keep reading miles plus your safety equipment will be powered up and function in case of an emergency. In addition that position is the one where your steering wheel unlocks and allows you to steer also.
If your van will not start from neutral then it has to be the way the neutral safety switch is configured on that vehicle. I always assumed all vehicles could be started from neutral. But if it can't, then suspend EOCing all together, because it is to dangerous otherwise to drive that way.

Simply consider neutral coasting with the engine on. On my 100 mile daily commute EOCing only gives me 2-3 mmpg bump, I consider it an advanced technique in order to meet agressive FE goals.

Changing your driving habits along with vehicle maintenance, practical aero mods and neutral coasting should set you on your way to MPG's well beyond the vehicles sticker without having to go nuts.

Good Luck ..

CODFISH was a joke acronym made up by a former GasSavers member: "Coasting On Demand, Fuel & Ignition SHut off", if memory serves. He was just poking fun at the ridiculous number of acronyms that seem to have been made up by the hypermiling community. (Also he was a native Newfoundlander, so there was some regional humour in there too...)

As for actually USING the technique, I wouldn't if your car isn't specifically designed for "flat towing". You may be causing cumulative damage to the transmission from lack of lubrication if the engine isn't turning the input shaft while the vehicle is coasting. Your owners manual should say whether it's acceptable or not.

trikkonceptz' advice of engine-on coasting is a decent option (if not quite as efficient).

I also think it's odd that the Caravan won't start in N. That strikes me as a potential safety concern. (If the engine should ever stall for any reason when in motion, you'd want to be able to attempt restarting it without having to come to a full stop.)

Try pressing the brake lightly while starting, most cars i've had will not start in park or neutral unless you press the brake. That's my guess.

Care to explain about FASing:p?

Forced auto stop is just a fancy acronym for shutting the engine off with the key - whether stopped or coasting.

It's called "forced" because the people who made it up mostly drive hybrids, which come with engine auto stop, but which don't shut off off under all conditions (thus some drivers were forcing it with the key).

Thanks! Then it is a form of EOC, just an even fancier term when done with non-hybrid cars.
Now back to CODFISH driving (basically the same thing, is it not?). Sorry for the interruption!

The distinction is that you can "FAS" when you're stopped. EOC (or CODFISH - which nobody really says around here :)) by definition includes coasting.

Thanks again for the quick response, and the patience, Captain Slow:turtle:! Hehe......

Driving on thin ice
 

I seem to have been able to ovecome the turning engine back on while costing in nuetral problem. I may have been coasting in "D" on the PRNDL.
Can I say PRNDL here? (Shifter)
As far as the Flat towing only I have to look that up in the manual and get back to you. Thanks for the heads up MetroMPG. I'm thinking I shouldn't because the car has a different smell to it after EOC driving.

Smoke the tranny to save a pint of gas. Sounds about right, for me.
Soon we will all be saving fuel al-a "Death Race 2000" I hate to say.......:eek:
