Because of the way gas engines are designed...with a throttle plate...it is usally more efficient to accelerate briskly...due to the fact that there is less restriction on the intake air when the throttle plate is farther open...WITHIN LIMITS of course. So you CAN have your cake and eat it too? This only works if you THINK AHEAD....and anticipate traffic/stops ahead.

What LOAD/RPM ranges have you observed that yield the best fuel economy? It seems the faster and harder I accelerate, the worse my numbers are yet I stay out of efficient gearing longer by accelerating slowly.

* I do try to coast down to 25 at stops and corners...but I don't mess with neutral or shutting the engine off (auto). I use a SG...and can see an obvious difference in mpg in N vs D. But it's too easy to get sloppy and possibly get into the wrong gear messing with neutral...so I don't do it.

Ive tried both methods of coasting using D and N. DFCO aside, which I have, the MPG numbers are about the same, spanning from the 50s to the 200s...depending on the speed and terrain. I like D just in case I need to accelerate to make it through a light or to avoid an accident.

* For a while I tried scrubbing speed off on corners by entering them a bit fast...but this WILL result in inner edge tire wear....so considering the cost of tires...not likely to be a winner.


Yes! Also, the gasoline splashes around and is harder on your suspension.


As far as auto transmissions...I always flush then from the radiator cooling lines....and also change the filter (no cheapies here!)/clean the pan. I also add a large neo magnet under the trans pan. I use synth trans oil...plus some Lubegard additive. This is preventive maintenance. Trannies are expensive to have fixed...and most can't do them themselves.

I don't know much about transmissions, so I usually have mine serviced at Toyota with OEM fluid.
