One tank on the Paseo - no P&G, no EOC - place your MPG bets

I've been thinking about doing this for a while now, and I am finally doing it. I'm going to drive one tank (maybe half a tank, we'll see) without using P&G (pulse and glide) or EOC (engine off coasting). I'm very interested in seeing how much my mileage drops due to abandoning these driving techniques. I'll still be using all other techniques, just getting rid of these more advanced ones.

The alternator disable won't be used since its still winter and that has killed the battery's capacity. But, everything else will be in use.

Winter has already hit the Paseo's mileage very hard, so I'm very unsure of what I'll get. Anyone want to take a guess at what kind of mileage I'll see?

Here is my mileage log:





One of the other reasons for doing this is that the EGR mod will be pretty useless if I still P&G. It was aimed at trying to find a solution to improve steady state driving mileage. This will give me a very rough idea of where I'd be starting from.

Well, your EPA highway rating is 34 mpg (US), and I definitely think you'll still beat that, since your commute is mostly highway. (And it's not high-speed, right?)

Plus you'll still be using your brain, and the car still has some efficiency boosting mods on it that raise its highway MPG above stock.

In which case I'm guessing 41 even.

My commute is mostly 55 mph highway. I will be doing 50-55. I'll also be doing the speed limit on normal streets.

I'm guessing 44mpg. Or maybe more, but 44 is my bet. Like Darin noticed, you'll be using your brain. Unless that also counts as a "more advanced technique"?

Thankfully, using my brain isn't an advanced technique. IMO this kind of driving is something ANYONE can do, even your grandma. I wouldn't tell her to go try and P&G or EOC haha.

51. It looks like the difference between two tanks between February and March '08 was about 6 mpg, I would expect that again if you were using the same techniques. Since you are not, the techniques will offset the gains from weather.

It looks like your winter mpg average is ~42-44 mpg. HS P&G doesn't raise mpg much - maybe 10%. So I'll guess 38-40 mpg sans P&G and EOC.
