just finished the tank full on Shell V Power and damm i filled up with 12 gallons and drove a total of 210 miles, so doing the math 210/12= 17.5 mpg wow thtas way better than my 230/15= 15.33 and i did the same route and same speed on purpose just to monitor my results so Shell is great and i felt it while driving next stop BP.

One question if u have an exhaust leak does that mean bad fuel economy too?maybe i have a small exhaust leak gotta chaeck again

 

hmmmmm.... cold gas expands? and better to fill up before 1/4 i have never noticed that but i will try ur advice and c wat hapens since im open to advice on saving gas ahhaha who isnt right?

 

dude what are you guys talking about.... it makes a minimal difference...

thats like taking a **** before you go driving...
