I don't want to do anything that will require the ICE to be turned off.
I'm sure with a couple of mods I should achieve 45mpg. Thanks to Matt's help I found the parts that I wanted to replace.
Here is my plan so far...
-NGK spark plug wires
-NGK spark plugs
-Replace entire PCV system(not just the PCV valve)
-Tires at max psi
-Get 2 LRR tires since I still have 2 tires that are good.
-Belly for the rear of the car
So do you think with these things 50mpg can be achieved?
It really depends on your drive. How long is your typical drive? Can you provide speeds, %city? How many cold starts per tank? Cold starts kill your FE.
With the Del Sol I could get 55MPG without turning off the engine. That is with 20 cold starts per tank and each trip was 25 miles, 50/50 city/hwy, 55 MPH max speed. I would think that you should get similar results with your DX.
Can 50MPG be achieved? Depending on your commute I don't see why not...
By comparison my Civic is ~200# heavier than yours, is sporting 4.07 final drive automatic transmission, and I clicked off my first 50.X MPG at this morning's fillup. No ICE off tactics - engine spinning the entire time I'm driving.
I'll argue that you need to get instrumented to really push yourself (my scangauge has been the difference), but I take it from past threads that that's not what you want to hear...
Congrats lindermant - looks like a record tank? I think it's possible (personally) to eke out very good city FE without instrumentation (p&g and codfishing oriented), but it's crucial for decent highway numbers. The difference between good and great cruising/instant mpg is imperceptible without feedback - unfortunately, unless you've tried it you likely won't believe that statement.
