Just wanted to share this. Recently I changed my air filter (3.6L) to a K & N drop in and went full synthetic. I drove 140 hi-way miles yesterday, cruise control set at 69 -70 mph. I was getting 26.9 MPG at one point it went over 27. Before I made these two changes my gas mileage was 24 to 25 mpg.
I too went full synthetic right after I bought my JGC V8 and a little later, I installed an AFE dry filter. I'm getting 20+ mpg in mixed city/highway driving. I have a 'soft' foot.
I have been tempted on getting a higher flow filter like K&N but after reading a test report and seeing the below graph and test reports, I immediately scratched off KN. AFE and AEM seem like better choices.
I added the AEM air filter. Notice no changes, but wasn't expecting much. We will see if anything changes in mpg dept. after this and synthetic oil which I would be surprised if it did.
That's nice milage in minnesota we have so much clean burn additional stuff added in the gas it kills milage when I get out of cit amd fill up it changes by 5 miles a gallon in my 5.7....
I was asked what my speed was when i averaged 30mpg on my trip from NJ to Indianapolis and back. I was driving 70 to 75 mph, sometimes better. This was with four passengers, luggage, and 10 bowling balls, driving in 90 degree heat with the air on. Both of my kids were competing in a national tournament in Indianapolis, thats why all the bowling balls.

Nice. I should receive my AEM tomorrow. I did an oil change last Saturday with Mobil 1 full syn. Crossing my fingers I get a bump in MPGs and a little extra low end torque for towing my little camping trailer.
