My sig is full...so I might as well move some of it into a thread and just put in a single link to the thread, right? From now on, I'll add things here and send people here to see them rather than trying to squeeze them into my sig.

Why MPG (or any Distance Per Volume) can be a difficult measurement to use instead of l/100km (or any Volume Per Distance):
Why using higher octane rated gas isn't going to help FE or power:

It looks like Bentley ( http://www.bentleypublishers.com
) doesn't offer online content, but most of the other repair manual companies (Chilton's, Helm, Alldata) offer online access for a fee.

A tire and gear calculator in the form of a Microsoft Excel spreadsheet:
Collections of calculators mainly for off-road truck configurations but may be useful for other purposes:
Another tire size calculator somewhat like the miata.net one in my sig
This one has more detail about gear ratios and requires you to enter more data, but calculates more driveline data.

The generally accepted authority for questions, data, and myth-busting about motor oil:

Weight: Does it really make that much of a difference? Well, not for bicyclists:
Ram Air Wind Alternator
More on weight reduction, with actual measured results
Weight Reduction for better FE
When it's all said and done, some cars
can have a measurable FE difference of ~1% MPG per 1% weight change -- so, to get a 10% change in MPG, one would add/remove 230 pounds on a 2300 pound Civic. Other cars may not respond
to weight loss at all, such as a 2.5% MPG change resulting from a whopping 19 percent weight change.
Stuff that's still in my sig:
Hypermiling/FE "sleepers" -- cars that get better FE than expected or respond particularly well to hypermiling techniques:
What are the hypermile "sleepers"
Good threads about drafting:
- In summary: A draft at highway speeds extends to three times the length of the vehicle, resulting in a 2 to 3 second following distance behind standard sized tractor-trailers -- that's not close, probably further than you were going to be anyway.
My DIY fuel rate meter thread:
DIY Fuel rate meter/injector duty cycle meter/GPH
- Also contains links to many other DIY fuel rate meter / MPG meter / electronic info threads
Tire pressure myths, facts, observations, effects:
In summary: You would probably benefit from additional tire pressure.
The effect of tire width on rolling resistance:
Low rolling resistance tires, which models are good:
Tire size calculator -- tells you the difference in diameter for any two sizes, and calculates speedometer/odometer error (and therefore your fudge factor for figuring your FE):
You're probably not actually lugging your engine when you use too high of a gear, just making it growl a little:
