Hi Richard -
I'll assume you're looking for feedback in this discussion thread, so everyone doesn't reply via email with the same suggestion(s).
One big oversight: In the
Tools of the Trade – Knowledge is Power section, I was very surprised you didn't mention using a digital fuel consumption gauge (whether factory equipped, aftermarket Scangauge/OBD-II or equivalent). That's consistently one of the
very first pieces of advice given to new members here. It's critical, in my opinion.
Yes, an inexpensive vac gauge will let a driver fine tune load while accel/cruising, but a resettable average MPG display is the proof in the pudding that the driving techniques (or mods) are working or not. Once a driver starts to monitor results on regular short trips (eg. commutes), modifying the nut behind the wheel becomes a much more satisfying & challenging game. There's a good reason the devices are called "game gauges" by some people, and you need a MPG display to provide the score.
There's a very good reason hybrids and EV's have sophisticated consumption displays (my 12 year old Insight has FIVE different ways to track fuel use - six, if you count the fuel gauge
).
Logging fuel consumption tank by tank at the gas station is way too slow / low resolution for most people who are serious about saving fuel.
