100 + hypermiling tips ...

[redneck]

I was reading over the tips and found something that the administrators may want to amend.

44) The most efficient way to slow down
When you *have* to slow down, here's an approximate heirarchy of methods, from best to worst.

1) coasting in neutral, engine off (ie. roll to a stop);
2) coasting in neutral, engine idling;
3) regenerative coasting (hybrid vehicles)
4) regenerative braking (hybrid vehicles)
5) coasting in "deceleration fuel cut-off" mode (in gear, above a certain engine RPM)
6) conventional friction braking (non-hybrid or hybrid)

Choosing the right method depends on traffic conditions (following vehicles) and how quickly you need to stop.

Manual or automatic...???

As we know, EOC in neutral with a automatic is a no-no.

It is well addressed in tip number 55. However, a reference here may also be helpful. We wouldn't want newbies to make a expensive mistake should they not fully read all the tips or understand the implications and or limitations of "Engine off coasting" a automatic .

A reference to tip number 55 could be added.

Just a thought...

Good idea. Will add that.

The list actually needs a general going-over. The list... is on the to-do list.

I make a point to WARN everyone who posts about neutral coasing in an auto. In many cases the transmission damage can exceed the value of the vehicle.

It would be a disaster for someone, trying to get above living day to day, to loose a vehicle trying to save a small amount of fuel.

DO NOT COAST WITH THE ENGINE OFF IN AN AUTOMATIC TRANSMISSION EQUIPPED VEHICLE. THE DAMAGE TO YOUR TRANSMISSION CAN BE CATASTROPHIC AND REQUIRE A COMPLETE TRANSMISSION REPLACEMENT.

I know some may not understand that, but they MUST understand this. Auto transmissions require pressure lubrication. Spinning parts in your transmission (Auto) without the engine running is the same as running your engine without oil in the oil pan.
Coasting is turning the prop shaft (or half shafts) and that turns a significant portion of the internal parts which require pressurized lubrication.

I think we could use something like a top 10 list too. Maybe right on the main page? 100+ is a bit intimidating/overwhelming, especially if you're not a car person.

I just read through all these tips, they were great! I couldn't believe how many of these I've picked up on my own over the past 15 years. I especially liked the "accordian"!
