Wow!!! You folks here have a wealth of knowledge/expertise to share! Thanks for making this possible.
I've been reading through the site for about 2 weeks now and began to use some of the techniques for the past 2 fill ups. I drive a 1998 Mazda 626 (4cyl auto) 25 miles (one way) to work everday here in the Chicagoland area and take regular trips to see family in Peoria & the Upper Pennisula of Michigan (U.P.) about 2x's per month. Peoria is 170 mi & the U.P. is 400 mi one way. To say the least I can save a forture by learning to increase my FE by even 5 mpg let alone the 15-20 mpg I am reading may be possible.
I became very excited on my first tank using the hypermiling techniques of FASing (while at lights), Nice on Coasting, DWB, DWL, Drafting, RR & increasing tires to max pressure (44 psi). Best MPG before was 32.05 & I attained 37.97 over 241 miles (170 was highway). Now I am a little dissapointed as I thought my techniques would have improved but I find that over the next 370 miles my mpg is only 32.70. As I reflect on the possible contributing factors (besides my lack of skill) I'm wondering what how much effect switching from RFG to straight gas & temperature has on MPG? In the Chicagoland area we have RFG but when taking trips it becomes a switch to straight gas for a 2 or more fill ups. I've noticed a trend when switching from RFG to straight I'm losing 3-4 mpg. I've read that the other, straight to RFG, you typically lose but not the other way around. Is this normal?
Now about this Pulse & Glide... what is the rate of acceleration? I've read much but and learn a ton but don't seem to know how quickly to accelerate. Do you creep up to the desired speed, 1/4, 1/2, 3/4 throttle? Seems that much can be determined by the terrain and traffic but let's just consider a 40 mph flat stretch of road with little traffic. What would be the expected acceleration rate. Range of speed would probably be 45-30 mph. Same question for warm up P&G. What is a good accel. rate? I think the 45 degree mornings the past few days have robbed me of a couple mpg and if I can master the warm up P&G I'm thinking it would greatly offset this loss.
Also - What mpg do you think this car is capable of?
So, Your comments, corrections & suggestions are welcomed as I can see considerable savings 'down the road'.
