are you kidding? the fuel savings (if any) from those mods will take 2.3 million years of offset the initial investment...

 

i do agree, i have a Injen CAI and Borla full cat back and gained at most 2MPG highway lol but the HP/Sound is why i got them

 

Yeah, that seems about right to me I was getting about 310 to 320 per tank...then I added borla headers, Berk HFCs, and Borla exhaust, transgo, etc., and I get between 320 to 340. But the sound keeps me wanting to keep my right foot buried most of the time ...OHHHH Yeahhhhh!!!!

 

oh man i so know what you mean bro... that beautiful borla growl then throaty growl is so addicting

 

I get maybe 300 per tank, but that's pretty rare so i say 250 and that's most city/highway driving.

 

I am at 300 now, I can do another 50 miles easy. And can prob push it over 400.

 

I get 260 on a full tank. 91
Shell

 

This is such a useless question because there are so many variables on "miles per tank"

For example, are you talking about the 16 gal you burn until the fuel light comes on, or the 20 gal until the tank runs dry? That could be as much as 100 miles right there

Just ask people what their avg MPG is... no better yet, just SEARCH IT as this has been covered 10,000 times in the past.

 

The mods are gonna happen anyway, I've only had it for 8 days and I'm completely in love with it. It does better than the tahoe I drove, so there is a gain for me.

 

Just check yesterday. 17 miles avg. mpg. Maybe I should slow down on the freeway. Just doesn't feel right if I am not driving between 70-85 mph on the freeway. City that's different.

 

about 80/20 city to hwy. Get about 16-18 mpg w/ the AC a blasting

 

400-450 per tank, mix of city and highway. No mods.

 

Wow! This is way more split than I thought.

I have two 12" subs...would that affect anything? Would a grounding kit help me if the subs did interfere?

 

I average about 18-19 in town driving and about 20-22 open road.

 

I got the car 2 weeks ago on friday, got 350 miles out of the tank (lasted me a week), fill up again on the next friday with a can of BG 44k and some Shell V-Power (91) and drove for another week got 400 mpt. This last friday i switched to Valvoline Synthetic Oil (5w30), a replacement K&N Air filter, filled up with just Shell V-Power (91) and ended up getting 250 miles from the first half of the tank with the a/c on. I want to see if i get to 480 or possibly 500 mpt. I did mixed city and highway driving about 30/70 (C/H%)
