How many gallon fillup for accurate MPG readings?
Hello all,
How much gas per fillup will give fairly accurate MPG readings? I am starting to pop regularly into the 40+ mpg range ("I'd like to thank the academy for this wonderful trophy- and of course, ecomodder for all the learnin"....) and am getting impatient driving 400 miles for results.....
I have a '87 CRX, so no scangauge, and I'm still researching mpguino, etc options....
- Is 5 gallons enough for a rough idea of MPG?
- I'm planning on 5 gallon fills(I still have a bunch of mods I want to test out), then if something causes a mpg spike, going back and averaging larger tanks for better accuracy.
---thoughts?
