Fuel Efficiency and the Yaris

[Boost Addicted]

lol my friend, I'm not driving an RX-8 with a wankel rotory engine... Our engine designs are nearly identical. Four pistons, same injection system, both gasoline engines, and so on... Theories that work on a Volkswagen will work on a Toyota, a Honda, a Ford, and so on. Both are manual transmissions... So think about it. And learn to read, because 34mpg is my combined city/highway. Pure highway is about 37mpg.


Must I say again, this is my two cents... Take it or leave it. I don't care. But please don't argue untill you read thuroughly and know the facts of the argument, like internal combustion engine function, and transmission syncro operation. Not tryin to be a dick here, my initial intentions were to help out. Clearly I am not, so I'll end this here... If I wanted to fight with people I'd head to vwvortex.

Actually, this can all be settled in a fairly straightforward way. As I've said before, we need data. And that's exactly what the Scangauge II collects very well.

To what temperature would you recommend warming the engine before starting to drive? (The "Cold" light goes off at 130F.)

I can simply pick, say, two very different courses. One which requires only light throttle to reach a particular close by destination. And another which involves getting right onto the highway.[1] Both courses can be run, always from a cold start at similar ambient temperature, with a warm up period, and without.

That should throw some illumination upon this subject of contention. And the results might suggest a further experiment or experiments. Arguing in a vacuum is kind of pointless.

This would address the fuel consumption issue. The engine wear issue is, unfortunately, more difficult to put numbers on.

That said, I'm off to the Rocky Mountains shortly, and will likely not begin to address this until at least early next week. But anyone with the proper instrumentation should feel free to start without me. ;-)

[1] Making certain, of course, that both courses are long enough that the engine is at 180F by the end of them, even without a separate warm up period.
