MPG updates

Thought Id give an update, after switching to Sunoco 89 for 87 mpgs went up and are now at 11 from 9.8-10.. Still a huge drop from before this issue came about, 12.2, but I didnt buy her for gas mileage!!! And yes you should switch to 89 as per factory recommendations..

Okay, I think I will do the switch and let it get to E then fill it w/ 89

I know this post was originally targeting HEMI's. But for you V6'ers. I just wanted to update that I haven't reset my mpg in almost 2 months, my combined MPG's is still going up. I'm getting 16.5.

Don't forget your odometer & speedometer are going to be off due to the tire size change. Until that's corrected, your "mpg" reading will be lower (you'll be traveling further than the computer thinks due to the increased tire diameter)

After my lift and tires im at 12.9 to 13.2 according to my evic. I have a light foot and was getting 13.5 to 14 prior (city driving). A lift and tires will get you less mpg if im not mistaken ;p?

I stopped looking at my evic because I just dont.care anymore LOL

Im at 12.3-12.5 with a lead foot and the sounds of the HEMI with the intake and exhaust is orgasmic!!! Lift, tires, added weight from skids will all affect mpg, but as long as its not 9.6 like I was getting before Im good with it

[Core XK]

lol Yeah 9.6 is pretty bad

I'm at 15.9 right now

After driving to gym/lunch, Im down to 12.2 cause its nice and cool out, so I was stretching the legs on her a bit!!! Interested in how the headers and possibly high flow cats will affect this... honestly I wont care!!!

I'm getting about 15.5 hwy(65mph) now 14 mixed and 11-12ish city with the 91oct tune from superchips. I'm pretty happy with that. Bet I could be 16 something hwy without my rack on top.
