To Impaler, What octane do you use, I use 87 octane but I don't get that kind of mileage... I get between 25-28 miles average.

my trip B is up to 53K with 24.6 mpg (accidentally hit reset around 100K and missed out on some good data..sigh). 140 miles a day highway so thats not too bad

this winter noticed i took a big hit for some reason . in summer i can get 3 days gas but now i have to fill up ever 2 days. unsure why. obviously my driving style is consistent so has to be the car.

i recently rented a maxima for across the country driving and was pretty impressed as i drive 90 to 100 in the wildnerness of NM and AZ (man theres nothing out there) 2900 miles and 26.3 mpg but that in cludes some local vegas driving too and my gfs slower foot helped too.

but nothing like the comfort of the impala. the maximas seats were way too form fitting.

2 RSA for sale. 7/32 good tread. berks county PA

166K on 2014 Blue Ray Metallic 2LTZ with 19s and nav. sadly new trans at 140K. Used to own 1995 DCM SS with only 260K!
