pg - am i doing this right?

If I downshift, the pulse MPG is a little lower, but I'm done with it a lot quicker.

I suppose I can ease up on the gas half-way through the pulse, letting it upshift back into 5th, then resume accelerating. (Assume I'm doing a 40mpg-50mph P&G). I guess this fits in line with the quote post.

What do y'all think?

That sounds right - force the shift, and then give it as much gas as you can without downshifting again.

I'll give it a shot.

Trying doing it, sort of, on the highway. Kept forgetting that it's not really worth it to P&G above 60mph.

So there's where my glass ceiling is! All my drives are either on 60km/h city streets or 100km/h highways and I'm only confident enough to do it on those highways, when it should be the opposite.

tried comparing rolling distance in a parking lot between nice on and nice off and didn't see a difference. Guess it was all in my head.

Finding that p&g works best for me on declines and at lower speeds( 30 to 45).

On highway p&g with nice-off in 40-55mph range I can only seem to get as good as 37.5 mpg. I'm just not getting enough benefit out of the glide at highway speed. I think I'.m going to try a little more air - perhaps 60 to 65psi. Currently I'm at 51psi(sidewall max). I. Nervous about trying lighter oil - car has less than 700 miles on it... Still breaking it it.

37.5 isn't bad considering my combined mpg is 22. Thinking that perhaps the ceiling for this vehicle is very close.

That appears to be the case. Rolling from 35 -> 25 mph takes a LOT longer than rolling from 65 -> 55 mph due to wind resistance, yet doesn't take as much to accelerate (neglecting the fact one is in different gears).

I took a trip the other week and sort of tested this. SR-520 from Brevard County to Orlando, FL (for those who know the area). 65mph speed limit. I pulsed pretty much from 55 to 65. I noticed that my fe really didn't increase as compared to DWL. In fact, I think it went slightly lower (numerous resets of trip FE on the scangauge). Now, if I was only pulsing 35-45 or so, it might be different...maybe even 45-55. But I couldn't go too slow...traffic was pretty non-existant (thankfully) but have a wife who complains about going too slow just to get a few extra miles out of the tank. *sigh*

I suppose even using CC at high speeds is better (not as good as DWL but a lot easier on the foot...I get cramps after a while).

What do others think? Does what I said sound about right?
