I commute every day for 25 miles and 20 miles are pure interstate with a 70 mph limit. I own a 98 Nissan Altima GXE and I was wondering if there is a specific speed I should go on the interstate to save gas. I was told 50 but its hard to believe I think its too low. Any ideas?

I am thinking of down grading to a Nissan Xterra 4×4 from my Chevy Tahoe 4×4. I am wondering how much better gas mileage the Xterra will get compared to the Tahoe? Any help would be great! Thanks!
